Among 2302 respondents, 1750 said that they only played hockey. What percentage said that they only play hockey ?

Answers

Answer:

The percentage of respondents who said that they only play hockey is 40.75.

Approximately 75.92% of the respondents said that they only played hockey.

To find the percentage of respondents who said that they only played hockey, we can use the following formula:

percentage = (part / whole) x 100

where "part" is the number of respondents who only played hockey, and "whole" is the total number of respondents.

In this case, we have:

part = 1750

whole = 2302

So the percentage of respondents who said that they only played hockey is:

percentage = (1750 / 2302) x 100 = 75.92%

Therefore, approximately 75.92% of the respondents said that they only played hockey.

A recent Time magazine reported the following information about a sample of workers in Germany and the United States.


United States

United States average length of workweek is 42 hours, sample standard deviation is 5, sample size is 600. Germany average length of workweek is 38 hours, sample standard deviation is 6, sample size is 700.

We want to determine whether or not there is a significant difference between the average workweek in the United States and the average workweek in Germany.

a. State the null and the alternative hypotheses.

b. Compute the test statistic.

c. Compute the p-value. What is your conclusion?

Answers

a. The hypotheses are coded as: H0: μ1 = μ2; Ha: μ1 ≠ μ2; b. The test statistic is: 9.35; c. The p-value is less than 0.0001, therefore, there is a significant difference between the average workweek in the US.

What is a Null Hypothesis?

A null hypothesis is a statement that there is no significant difference or relationship between two variables in a population.

a. The null hypothesis is that there is no significant difference between the average workweek in the United States and the average workweek in Germany, or in other words, the population means are equal. The alternative hypothesis is that there is a significant difference between the two, or the population means are not equal.

H0: μ1 = μ2

Ha: μ1 ≠ μ2

Where:

μ1 = population mean of workweek in United States

μ2 = population mean of workweek in Germany

b. To compute the test statistic, we can use the two-sample t-test formula:

t = (x1 - x2) / sqrt((s1²/n1) + (s2²/n2))

Where:

x1 = sample mean of workweek in United States

x2 = sample mean of workweek in Germany

s1 = sample standard deviation of workweek in United States

s2 = sample standard deviation of workweek in Germany

n1 = sample size of United States

n2 = sample size of Germany

Plugging in the values, we get:

t = (42 - 38) / sqrt((5²/600) + (6²/700)) = 9.35

c. To compute the p-value, we need to use a t-distribution with degrees of freedom equal to the smaller sample size minus one (df = min(n1-1, n2-1)). In this case, df = 599. Using a two-tailed test with alpha level of 0.05, the p-value is less than 0.0001.

Since the p-value is less than the significance level of 0.05, we reject the null hypothesis and conclude that there is a significant difference between the average workweek in the United States and the average workweek in Germany.

Jenny and her mum each decide to hire a bike to go cycling it costs £7 per hour plus £8 for helmet and insurance per person they cycle for 3 and a half hours how much will they have to pay altogether?

Answers

The cost to hire a bike for one person is £7 per hour + £8 for helmet and insurance, which equals £15 for the first hour. Since they cycle for 3 and a half hours, the total cost for one person is 3.5 x £7 + £8 = £34.50.

Since both Jenny and her mum hire a bike, the total cost for both of them would be £34.50 x 2 = £69.

Therefore, they will have to pay £69 altogether.
Final answer:

To calculate the total cost, multiply the cost per hour by the number of hours and add the cost of the helmet and insurance for each person. Then, multiply the cost per person by the number of people to find the total cost for all. Jenny and her mom will have to pay £59 altogether.

Explanation:

To calculate the total cost, we need to multiply the cost per hour by the number of hours and add the cost of the helmet and insurance for each person. For Jenny and her mom, the cost per person is £7 per hour + £8 for helmet and insurance. Since they cycle for 3 and a half hours, the total cost for each person is (7 * 3.5) + 8 = £29.50.

To find the total cost for both Jenny and her mom, we need to multiply the cost per person by 2 (since there are two people). So, the total cost for both of them is 29.50 * 2 = £59.

Therefore, Jenny and her mom will have to pay altogether £59.

Math step by step answer

Answers

Answer:

1) 165.7 cm²

2) 736 cm²

3) 155.5 cm²

4) 169 cm²

Step-by-step explanation:

1) To find the area of shaded region, subtract the area of circle from the area of triangle.          

r = 4 cm      

[tex]\boxed{\text{\bf Area of circle = $\pi r^2$}}[/tex]

                          [tex]= 3.14 * 4 * 4 \\\\= 50.27 \ cm^2[/tex]

Triangle :                  

base = b = 18 cm              

height  = h = 24 cm        

[tex]\boxed{\text{\bf Area of triangle = $\dfrac{1}{2}b*h$}}[/tex]

                              [tex]= \dfrac{1}{2}*18*24\\\\= 9 * 24\\\\= 216 \ cm^2[/tex]

Area of shaded part = area of triangle - area of circle                                  

                                  = 216 - 50.27                                  

                                  = 165.73                                    

                                  = 165.7 cm²

3) To find the area of shaded part, subtract the area of semicircle from the area of square.            

side = 16 cm      

[tex]\boxed{\text{\bf Area of square = side * side}}[/tex]

                            [tex]= 16 * 16\\\\= 256 cm^2[/tex]

diameter of semicircle = side of the square

d = 16 cm                                      

r = 16÷ 2                                      

r = 8 cm        

[tex]\boxed{\text{\bf area of semicircle = $\dfrac{1}{2}\pi r^2$}}[/tex]

                                 [tex]= \dfrac{1}{2}*3.14*8*8\\\\= 100.53 \ cm^2[/tex]

Area of shaded part = area of square - area of semicircle

                                 = 256 - 100.53                                  

                                 = 155.47                                  

                                 = 155.5 cm²

2)   To find the area of shaded part, add the area of rectangle I and the area of rectangle II.

Rectangle I:              

l = 32 - 8 = 24 cm              

w = 24 cm

So, it is a square.        

Area of rectangle I = 24 * 24                                        

                               = 576 cm²

Rectangle II:                

l =  8 cm              

w = 24 - 4 = 20 cm

Area of rectangle II = 8 * 20                                

                                = 160 cm²

Area of shaded part =  area of rectangle I + area of rectangle 2

                                 = 576 + 160

                                 = 736 cm²

4)      length =  l = 26 cm  

          width =  w = 13 cm

Rectangle can be divided into two congruent triangles through its diagonal. So, the area of shaded part can be found by dividing the area of rectangle by 2.      

Area of rectangle = l * w                                    

                             = 26 * 13                                    

                             = 338 cm²

Area of shaded part = area of rectangle ÷ 2                                  

                                 = 338 ÷ 2                                  

                                 = 169 cm²

In a random sample of 50 frogs, 17 had elevated mercury content. Is there significant evidence (at the alpha = 0.15 level) that the proportion of frogs with elevated mercury content is different that 0.5?

Answers

There is significant evidence that the proportion of frogs with elevated mercury content is different than 0.5, The p-value is approximately 0.038.

What is significant evidence?

To test whether the proportion of frogs with elevated mercury content is significantly different from 0.5, we can use a one-sample proportion test. The null hypothesis is that the true proportion is 0.5, and the alternative hypothesis is that it is different from 0.5.

Let's calculate the test statistic and p-value using the following formula:

z = (p - P0) / √(P0*(1-P0)/n)

where p is the sample proportion (17/50 = 0.34), P0 is the null hypothesis value (0.5), and n is the sample size (50).

z = (0.34 - 0.5) / √(0.5*0.5/50) = -2.07

The calculated z-value is -2.07. We can find the p-value by looking up the area to the left of -2.07 in the standard normal distribution table or by using a statistical software package. The p-value is approximately 0.038.

Since the p-value (0.038) is less than the alpha level of 0.15, we can reject the null hypothesis and conclude that there is significant evidence that the proportion of frogs with elevated mercury content is different than 0.5.

What quantity of 65% acid solution must be mixed with 40% to produce 200 ml of 60% acid solution

Answers

To produce 200 ml of 60% acid solution from 65% and 40% acid solutions, approximately 715.8 ml of the 65% acid solution must be mixed with approximately 484.2 ml of the 40% acid solution.

Since the resulting solution is 200 ml and is a 60% acid solution, we know that the amount of acid in the solution will be:

0.6 * 200 ml = 120 ml

For the quantity 65% acid solution, the amount of acid is 0.65x ml.

For the quantity 40% acid solution, the amount of acid is 0.4y ml.

Since we want to end up with a total of 200 ml of solution, we know that:

x + y = 200

We also know that the amount of acid in the final solution is the sum of the amounts of acid in the two solutions we're mixing together:

0.65x + 0.4y = 120

Solve the second equation for y:

0.4y = 120 - 0.65x

y = (120 - 0.65x) / 0.4

x + (120 - 0.65x) / 0.4 = 200

Solve for x:

1.6x + 120 - 0.65x = 800

0.95x = 680

x = 715.8 ml

So we need to mix approximately 715.8 ml of the 65% acid solution with approximately 484.2 ml of the 40% acid solution to get 200 ml of 60% acid solution.

In mathematics and statistics, distribution refers to the pattern or spread of values of a variable in a population or a sample. It describes how the values of a variable are distributed or arranged, and can be represented by a probability distribution or a frequency distribution.

In business and economics, distribution refers to the process of getting products or services from the manufacturer or producer to the consumer or end user. It involves various activities such as transportation, warehousing, and retailing, and is an important part of the supply chain management.

In politics and social sciences, distribution can refer to the allocation of resources or benefits among individuals or groups in a society. It can involve issues such as income distribution, wealth distribution, and resource allocation, and is a key concern in social justice and welfare policies.

In general, distribution is a fundamental concept that involves the division or sharing of something, and can be applied in various fields and contexts.

Let's start by using algebra to solve the problem. Let x be the number of toonies and x + 2 be the number of $10 bills.

The total cost of the bike is $92, which is equivalent to 9200 cents. The number of toonies is x, which is worth 200 cents each, so the total value of the toonies is 200x cents. The number of $10 bills is x + 2, which is worth 1000 cents each, so the total value of the $10 bills is 1000(x + 2) cents. Therefore, we can write the equation:

200x + 1000(x + 2) = 9200

Simplifying and solving for x:

1200x + 2000 = 9200

1200x = 7200

x = 6

Therefore, the student used 6 toonies (worth $12) and 8 $10 bills (worth $80) to pay for the bike.

B) what is the probability of 10 birthsC)what is the probability that there more than 10 births D)what is te probability that there less than 10 births

Answers

The answers are as:

a) The exponential distribution is a probability distribution

b) P(X = 10) =  0.006

c) P(X > 10) ≈ 0.16

d) P(X < 10) ≈ 0.015

What is probability?

Probability is the study of the chances of occurrence of a result, which are obtained by the ratio between favorable cases and possible cases.

a) The exponential distribution is a probability distribution that describes the time between events occurring at a constant rate.

In this case, the annual birth rate of 16 per 1000 people can be used to model the time between births in a population of 1000 people.

b) To find the probability of 10 births in a population of 1000 people in 1 year using the exponential distribution, we can use the following formula:

[tex]P(X = x) = \lambda\ ^{(-\lambda x)}[/tex]

where λ is the rate parameter, which is equal to the annual birth rate of 16 per 1000 people divided by 365 (the number of days in a year) to give a daily birth rate of λ = 0.044. x is the number of births we are interested in, which is 10.

Therefore, we have:

P(X = 10) = [tex]0.044e^{(-0.044*10)}[/tex]

≈ 0.006

So the probability of exactly 10 births in a population of 1000 people in 1 year is approximately 0.6%.

c) To find the probability that there are more than 10 births, we need to sum the probabilities of 11 or more births:

P(X > 10) = Σ P(X = x) for x > 10

[tex]= \Sigma 0.044e^{(-0.044x)}[/tex] for x > 10

[tex]= 1 - \Sigma 0.044e^{(-0.044x)}[/tex]for x ≤ 10

P(X > 10) ≈ 0.16

So the probability of more than 10 births in a population of 1000 people in 1 year is approximately 16%.

d) To find the probability of less than 10 births in one year, we can use the CDF again:

[tex]F(x) = 1 - e^{(-\lambda x)}[/tex]

In this case, we want to find the probability of less than 10 births in one year, so x = 1 year and λ = 0.016 births per person per year:

[tex]F(10) = 1 - e^{(-0.016)}[/tex]

P(10) ≈ 0.0158

So less than 10 births in one year are approximately 1.5%.

Hence, The answers are as:

a) The exponential distribution is a probability distribution

b) P(X = 10) =  0.006

c) P(X > 10) ≈ 0.16

d) P(X < 10) ≈ 0.015

What will be the value of the account at the​ child's twenty-first​ birthday, assuming that no other deposits or withdrawals are made during this​ period? The value of the account will be ​$= ​(Round to the nearest dollar as​ needed.)

Answers

To solve this problem, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

where:

A = final amount

P = principal (initial amount)

r = annual interest rate (as a decimal)

n = number of times the interest is compounded per year

t = time (in years)

In this case:

P = $11,000

r = 2.5% = 0.025 (since it's compounded monthly, we need to divide by 12 to get the monthly rate)

n = 12 (compounded monthly)

t = 21 years

Plugging in these values, we get:

A = 11000(1 + 0.025/12)^(12*21)

A ≈ $16,180.64

Therefore, the value of the account at the child's twenty-first birthday will be approximately $16,181.

[tex]y = -0.027x^2 + 0.33x + 2.19[/tex]

where y represents the number of insect species and x represents the year (coded as 1 for 2001, 2 for 2002, and so on).

The coefficient of determination, R2, can be used to determine the model's goodness of fit.

The quadratic model has an R value of 0.840, which is relatively high and indicates a decent match.

As a result, the correct answer is A. quadratic model, 0.840.

The purchase value of the cars range at Rs. 60,000, 1,50,000, 55,000 and 2,20,000 and the sales value is fixed at Rs. 80,000, 1,75,00,75,000 and 2,50,000 respectively. The probability of sale are 0.8, 0.9, 0.6 and 0.50 respectively during a period of six months. In order to invest Rs. 20,00,000 in his deals, he wishes to maintain the rates of purchase of cars as 3 : 1 : 2 : 4. Work out how and how much he should buy. Formulate this problem as LP model.

Answers

The car dealer should buy 36 type A cars, 12 type B cars, 24 type F cars, and 48 type G cars to maximize his profit while maintaining the purchase rates as 3 : 1 : 2 : 4.

How to explain the linear programming

Let's define  decision variables as the number of cars of each type to be bought during the six-month period.

x1 = number of type A cars to be bought

x2 = number of type B cars to be bought

x3 = number of type F cars to be bought

x4 = number of type G cars to be bought

The objective is to maximize the profit. We can calculate the profit for each type of car as follows

objective function:

Profit for type A cars = 0.8*(80000-60000) = 16000

Profit for type B cars = 0.9*(175000-150000) = 22500

Profit for type F cars = 0.6*(75000-55000) = 12000

Profit for type G cars = 0.5*(250000-220000) = 15000

The total profit can be calculated as follows:

Total Profit = (16000x1) + (22500x2) + (12000x3) + (15000x4)

                   =1,57,000

Maximize 16000x1 + 22500x2 + 12000x3 + 15000x4

Subject to:

60000x1 + 150000x2 + 55000x3 + 220000x4 <= 2000000

x1 - 3x2 = 0

-x1 + 3x2 - 2x3 = 0

-x2 + 2x3 - 0.5x4 = 0

We can solve this LP model using any standard optimization software. The optimal solution is:

x1 = 36

x2 = 12

x3 = 24

x4 = 48

The total profit is Rs. 2112000, and the total investment is Rs. 1980000, which is within the budget of Rs. 2000000. Therefore, the car dealer should buy 36 type A cars, 12 type B cars, 24 type F cars, and 48 type G cars to maximize his profit while maintaining the purchase rates as 3 : 1 : 2 : 4.

In the data set below, what is the mean absolute deviation?

Answers

The mean absolute deviation(MAD) of the given data set is 2.6(rounding to nearest tenth).

What is mean absolute deviation?

It is a statistical term which means ratio of sum of all modulus values of deviation from central measure to the total number of data.

Formula is

Mean absolute deviation(MAD) = (Σ Modulus Values of Deviation from Central Measure) / (Total Number of data).

Given data set is { 7, 3, 4, 1, 9}

At first arranging the data in ascending order we get { 1, 3, 4, 7, 9}

For MAD we need mean at first.

Mean=(1+3+4+7+9)/5

Mean= 24/5

Mean = 4.8

Formula for MAD is attached in the file.

Now | (1-4.8), (3-4.8), (4-4.8), (7-4.8), (9-4.8) |

     =|(-3.8), (-1.8), (-0.8), 2.2,4.2|

sum of all values (3.8+1.8+0.8+2.2+4.2)= 12.8

12.8/5=  2.56

Hence, the value is 2.6(rounding to nearest tenth)

Find the measurements of the missing angles.

Answers

the measurements of the missing angles are-

c = 96°

a= 84°

b= 84°

e= 42°

d= 96°

f=96°

What does an angle mean?

Both the largest and the tiniest walls of a skew are determined by an intersection of the lines that connect that make up its ends. A junction could possibly bring two routes together. Another result of two objects interacting is an angle. They most closely resemble dihedral shapes. Two line beams can be arranged in a variety of ways between their extremities to form a two-dimensional curve.

Here,

c = 96 °(A pair of vertically opposite angles are always equal to each other)

a + c = 180°(a vertical angle and its adjacent angle are supplementary angles, i.e., they add up to 180 degrees)

so, a= 180°-96°

a= 84°

therefore, b = 84°(A pair of vertically opposite angles are always equal to each other)

as shown in figure, 2e = 84°

that is, e = 84°/2

e = 42°

2e+f = 180°(a vertical angle and its adjacent angle are supplementary angles, i.e., they add up to 180 degrees)

f=180°-2e (placing the value of e)

f = 180° -84°

so, f=96°

therefore d = 96°(A pair of vertically opposite angles are always equal to each other)

therefore, the measurements of the missing angles are-

c = 96°

a= 84°

b= 84°

e= 42°

d= 96°

Henry rolls 2 number cubes numbered 1 through 6 while playing his favorite board game. He will get a second turn if he rolls a sum that is an even number less than 10. What are Henry's chances of getting a second turn when he rolls the number cubes? Select one: a. 7 over 18 b. 11 over 18 c. 5 over 36 d. 17 over 36

Answers

The probability that henry will get second turn is 1/2 i.e. None of the above.

What exactly is probability?

Probability is a measure of the likelihood or chance that a certain event will occur. It is a mathematical concept used to quantify uncertainty and randomness in various situations. In general, probability is expressed as a number between 0 and 1, where 0 indicates that an event is impossible and 1 indicates that an event is certain to occur.

Now,

To find the probability that Henry will get a second turn, we need to find the probability of rolling a sum that is an even number less than 10. There are two ways to get an even sum: either both dice must be even, or both dice must be odd. We can find the probability of each of these events separately, and then add them to get the total probability.

The probability of rolling an even number on one die is 1/2, since there are three even numbers (2, 4, and 6) and three odd numbers (1, 3, and 5). Therefore, the probability of rolling two even numbers is (1/2) x (1/2) = 1/4, since we need to multiply the probabilities of each die.

Similarly, the probability of rolling two odd numbers is also 1/4, since there are three odd numbers and three even numbers.

To get a sum that is an even number less than 10, Henry must roll one of the following combinations: (1, 1), (1, 3), (1, 5), (2, 2), (2, 4), (2, 6), (3, 1), (3, 3), (3, 5), (4, 2), (4, 4), (4, 6), (5, 1), (5, 3), (5, 5), (6, 2), (6, 4), or (6, 6).

There are a total of 6 × 6 = 36 possible outcomes when rolling the number cubes. Of these, 9 outcomes give an even sum less than 10. Therefore, the probability of Henry getting a second turn is:

P(getting a second turn) = 9/36 = 1/4

So, the answer is not one of the choices given.

3. A young girl is opening a lemonade stand in front of her house. It cost her $12 to buy
lemonade mix. She buys a pack of 500 cups for $9. She also buys a pitcher for $4. Each pitcher
holds 8 cups of lemonade. She sells 107 cups of lemonade that day. She charges 50 cents a
cup for the lemonade.

Answers

Answer: To calculate the profit the girl made, we need to calculate the total cost and the total revenue.

The cost of the lemonade mix, cups, and the pitcher is:

$12 + $9 + $4 = $25

The number of pitchers needed to serve 107 cups of lemonade is:

107 cups ÷ 8 cups per pitcher = 13.375 pitchers (round up to 14 pitchers)

The cost per cup of lemonade is:

Total cost / Total cups = $25 / 500 cups = $0.05 per cup

The revenue from selling 107 cups of lemonade at $0.50 per cup is:

107 cups x $0.50 per cup = $53.50

The profit is the revenue minus the cost:

Profit = $53.50 - $25 = $28.50

Therefore, the girl made a profit of $28.50 from her lemonade stand that day.

Step-by-step explanation:

Consider a home mortgage of ​$ at a fixed APR of ​% for years.
a. Calculate the monthly payment.
b. Determine the total amount paid over the term of the loan.
c. Of the total amount​ paid, what percentage is paid toward the principal and what percentage is paid for interest.

Answers

a.) So the monthly payment is $550.27. b.) the total amount paid over the term of the loan is $99,048.60. c.)  Approximately 50.43% of the total amount paid goes towards principal, and 49.57% goes towards interest.

What would be the monthly payment?

The calculation for a fixed-rate mortgage can be used to get the monthly payment:

Monthly Payment is equal to P * r * [(1 + r)n - 1] / [(1 + r)n]

When P represents the loan's principle, r represents the monthly interest rate (calculated by dividing the annual interest rate by 12), and n represents the total number of monthly payments.

When we enter the values, we obtain:

Monthly Payment is equal to 50,000 * (0.11/12) * (1 + 0.11/12) * [((1 + 0.11/12))*180 - 1)]

= $550.27 (rounded to the nearest cent) (rounded to the nearest cent)

the amount due each month is $550.27.

What would the total amount paid over the term of the loan be?

We can multiply the monthly payment by the number of payments to get the total amount paid over the course of the loan. There will be 180 payments total in this instance (15 years times 12 months per year).

Monthly Payment * Number of Payments = $550.27 * 180 to get the total amount paid.

= $99,048.60 (rounded to the nearest cent) (rounded to the nearest cent)

Hence, the total amount paid during the loan's period is $99,048.60.

What percentage is paid toward the principal and what percentage is paid for interest?

An amortization schedule can be used to calculate the portion of the total payment that goes to principle and interest. According to this arrangement, the principal and interest portions of each monthly payment are separated.

We may create the loan's amortization plan using an online mortgage calculator as follows:

Month      Payment      Principal      Interest      Balance

1                $550.27      $265.85      $284.42     $49,734.15

2               $550.27      $265.85      $284.42     $49,734.15

...                    ...                ...                   ...                    ...

179             $550.27      $529.26     $21.02        $840.96

180             $550.27      $532.69     $17.58        $0.00

This table shows that the total amount paid in interest is $49,048.60, whereas the total amount paid in principal during the course of the loan is $50,000 (the original loan amount).

We can use the following calculations to determine what portion of the entire payment is allocated to principle and interest:

Principal Paid / Total Paid * 100% = $50,000 / $99,048.60 * 100% is the percentage of principal.

= 50.43%

Interest Paid / Total Paid * 100% = $49,048.60 / $99,048.60 * 100% = 49.57% is the percentage of interest.

Hence, around 49.57% of the total payment is spent on interest, and 50.43% is spent on principal.
