Determine the point estimate of the population​ proportion, the margin of error for the following confidence​ interval, and the number of individuals in the sample with the specified​ characteristic, x, for the sample size provided.

Lower bound = 0. 123​,

upper bound = 0. 607​,

n = 1000

Answers

Answer 1

The point estimate of the population​ proportion, the margin of error is 0.365.

Margin of error is a statistic that expresses the amount of random sampling error in survey results. The larger the margin of error, the less confident people are that the poll results will reflect the overall census results. When the population is incompletely sampled and the resulting measure has a positive variance, the margin of error will be positive, i.e. the measures differ. The term margin of error is often used in non-survey contexts to refer to the error observed in the reporting of measured quantities.

According to the Question:

Given that:

Lower bound = 0.123​,

Upper bound = 0.607​,

n = 1000

P = Lower Bound + Upper Lower /2

  = 0.123 + 0.607/2

Alexander owes \$3,200$3,200 on his credit card. The bank charges an annual interest rate of 16. 8%, compounded monthly. If Alexander wants to pay off his credit card using equal monthly payments over the next 8 months, what would the monthly payment be, to the nearest dollar?

Answers

Alexander would need to make monthly payments of $430 for the next 8 months to pay off his credit card debt.

To calculate the monthly payment that Alexander needs to make, we can use the formula for the present value of an annuity, which is:

[tex]PMT=PV*(r*(1+r)^n)/(1+r)^n-1)[/tex]

Where:

PMT = Monthly payment

PV = Present value of the debt

r = Monthly interest rate

n = Total number of payments

First, we need to calculate the monthly interest rate. The annual interest rate is 16.8%, which means the monthly interest rate is 16.8%/12 = 1.4%.

Next, we can calculate the total number of payments that Alexander needs to make over 8 months.

n = 8

Now, we can plug in the values:

[tex]PMT = 3200*\frac {(0.014*(1+0.014)^8)}{((1+0.014)^8-1)}[/tex]

This works out to approximately $430 per month (rounded to the nearest dollar).

Therefore, Alexander would need to make monthly payments of $430 for the next 8 months to pay off his credit card debt.

Answers

This gives us the answer of 1.9 miles, meaning that he must ride an average of 1.9 miles each day for the remaining 4 days of the week in order to reach his goal of 39.6 miles.

(39.6 - 8) ÷ 4 = x

7.6 ÷ 4 = x

x = 1.9 miles

Bentley wants to ride his bicycle 39.6 miles this week. He has already ridden 8 miles, leaving him with 31.6 miles left to ride. He has 4 days left to ride, so we need to figure out how many miles he must ride each day in order to meet his goal. We can do this by subtracting the 8 miles he has already ridden from the total goal of 39.6 miles. This gives us 31.6 miles remaining to be ridden. We then divide this number by 4, since he has 4 days left in the week to ride. This gives us the answer of 1.9 miles, meaning that he must ride an average of 1.9 miles each day for the remaining 4 days of the week in order to reach his goal of 39.6 miles.

Therefore, the length of side AC in triangle ABC is approximately 14.6 units.

What is triangle?

A triangle is a closed two-dimensional geometric shape that is formed by connecting three non-collinear points with straight line segments. Each of these line segments is called a side, and the point where two sides meet is called a vertex. A triangle has three vertices, three sides, and three angles. Triangles can be classified based on the length of their sides and the size of their angles.

Here,

We can use the sine rule to find the length of side AC in triangle ABC, where angle A = 32° and AB = 8. The sine rule states that for any triangle ABC:

a/sin(A) = b/sin(B) = c/sin(C)

where a, b, and c are the lengths of the sides opposite to the angles A, B, and C, respectively.

In this case, we know the length of side AB (a = 8) and the measure of angle A (A = 32°), so we can set up the following proportion:

a/sin(A) = c/sin(C)

Substituting the values, we get:

8/sin(32°) = AC/sin(C)

Solving for AC, we get:

AC = (8/sin(32°)) * sin(C)

To find sin(C), we can use the fact that the sum of the angles in a triangle is 180°. So, we have:

C = 180° - 90° - A

C = 180° - 90° - 32°

C = 58°

Substituting this value, we get:

AC = (8/sin(32°)) * sin(58°)

AC ≈ 14.6

Answers

The inequality that describes the problem when coach Yamada is organizing community volleyball teams is x ≤ 9.

Why is x ≤ 9 the correct inequality that describes the problem when coach Yamada is organizing community volleyball teams? Here is why: We know that coach Yamada wants each team to have 8 players but he can't make as many full teams as he wanted to because fewer than 80 people signed up.

Let x represent the number of full teams coach Yamada can make. We know that 1 team can have 8 players. Therefore, the number of players needed for x full teams = 8xWe also know that fewer than 80 people signed up. So, 8x < 80, if more than 80 people signed up then coach Yamada would be able to make more than x full teams.

Since coach Yamada can't make a fraction of a team so x should be an integer. Therefore, the solution for 8x < 80 is x ≤ 9.Therefore, x ≤ 9 is the inequality that describes the problem when coach Yamada is organizing community volleyball teams.

1. ) A shoe salesman sold $4,125 in shoes. He earns a 4% commission. If his base salary is $2000, how much did he earn in total. Be sure to show the formula you use to solve

Answers

the shoe salesman earned a total of $2,165. To calculate the total earnings of the shoe salesman, we need to determine both his commission and base salary.

First, we can calculate his commission by multiplying the total amount of shoes he sold by his commission rate:

Commission = Total shoes sold * Commission rate

Commission = $4,125 * 0.04

Commission = $165

Next, we can add his commission to his base salary to determine his total earnings:

Total earnings = Commission + Base salary

Total earnings = $165 + $2,000

Total earnings = $2,165

Therefore, the shoe salesman earned a total of $2,165.

It's important to note that commission is a percentage of sales, and it can be a motivating factor for salespeople. A commission-based salary rewards high performers and incentivizes them to sell more. However, commission rates may vary depending on the industry, product, and company policies. Some companies may offer a higher commission rate for selling high-end products or for meeting or exceeding sales targets.

In conclusion, the shoe salesman earned $2,165 in total, which includes his commission and base salary. Commission-based salaries can be an effective way to motivate salespeople and incentivize high performance.

An angle measurement, m∠BOC = 60° degrees where O is the center of the corcle.

What is an angle?

Since the ΔABC has three similar sides, we know that it is an equilateral triangle, meaning that all three angles are equal and each angle measures 60°.

Since A, B, and C are points on a circle with O as the center, we know that each of the distances OA, OB, and OC is equal to the radius of the circle.

Let's call this radius r.

Since ΔABC is equilateral, we know that each side has length r. We can also draw radii from the center O to points A, B, and C to form three congruent triangles AOB, BOC, and COA, each with two sides of length r and one angle of 60°.

Since the sum of the angles in a triangle is 180° degrees, each of the other two angles in each of these congruent triangles must measure 60° as well.

Thus, we see that ∠BOC is one of the angles in the isosceles ΔBOC, which has two angles of 60° and a third angle x, which we want to find.

We can use the fact that the sum of the angles in a triangle is 180° to find x:

x + 60 + 60 = 180

Simplifying, we get:

x = 60

Therefore, angle BOC measures 60°

Identify the radius and the center of a circle whose equation is (x â€" 5)² y² = 81. the radius of the circle is units. the center of the circle is at ( , ).

Answers

The radius of the circle is 9 units. The center of the circle is at (5, 0).

The given equation is (x – 5)²y² = 81.

To identify the radius and center of this circle, we can rewrite the equation in standard form.

First, let's divide both sides by 81 to get (x – 5)²y²/81 = 1.

Next, we can take the square root of both sides to eliminate the squared terms.

This gives us the equation (x – 5)/9 · y/3 = 1.

The standard form of a circle is (x – h)² + (y – k)² = r², where (h, k) is the center of the circle and r is the radius.

Comparing this form to our equation, we can see that (x – 5)/9 and y/3 correspond to (x – h) and (y – k), respectively.

Therefore, we can solve for h and k by setting (x – 5)/9 = 0 and y/3 = 0, respectively.

This gives us h = 5 and k = 0, so the center of the circle is (5, 0). Finally, we can solve for the radius r by noting that the

distance from the center (5, 0) to the edge of the circle is 3 units in the x-direction and 9 units in the y-direction.

Therefore, the radius of the circle is 9 units, and we can express our final answer as:

The radius of the circle is 9 units. The center of the circle is at (5, 0).

Therefore, the temperature will be 17°C in the months of [tex]x = 4 + 48k[/tex] or    [tex]x = 20 + 48k,[/tex] where k is an integer.

What is temperature?

Temperature is a measure of the average kinetic energy of the particles in a substance. In simpler terms, it is a measure of how hot or cold something is. The temperature is usually measured using a thermometer, which can be a simple device such as a mercury or alcohol thermometer, or a more complex electronic device such as a thermocouple or infrared thermometer. The standard unit of measurement for temperature is the degree Celsius (°C) or Fahrenheit (°F), although the Kelvin (K) scale is also commonly used in scientific contexts.

To find in which months the temperature will be 17°C, we need to solve the equation:

[tex]f(x) = 17[/tex]

Substituting the given equation of f(x), we get:

[tex]5 cos(x/12) + 14.5 = 17[/tex]

Simplifying this equation, we get:

[tex]cos(x/12) = 0.5[/tex]

[tex]cos(x/12) = cos(π/3 + 2kπ) or cos(x/12) = cos(5π/3 + 2kπ)[/tex]

cos(5π/3) = -0.5. Also, cos(x) has a period of 2π. Therefore, we can write:

[tex]cos(x/12) = cos(π/3 + 2kπ) or cos(x/12) = cos(5π/3 + 2kπ)[/tex]

where k is an integer.

Solving for x, we get:

[tex]x/12 = π/3 + 2kπ or x/12 = 5π/3 + 2kπ[/tex]

[tex]x = 4π + 24kπ or x = 20π + 24kπ[/tex]

Multiplying both sides by 12, we get:

A merry-go-round rotates from rest with cons†an t angular acceleration 'alpha'. ratio of time to rotate first 2 revolutions and next 2 revolutions i.

Answers

The required ratio of the time to rotate first and next 2 revolution is given by option 2. (√2+1) : 1.

Merry go round starts from rest.

Let us assume that the initial angular velocity and displacement are zero. Final angular velocity after 2 revolutions is ω.

This implies,

ω₀ = 0 rad/s.

For first two revolutions of the merry go round we have,

θ = 2×2π rad

⇒ θ = ω.t₁ + 1/2 × α × t₁²

⇒ 2×2π = 0×t₁ + 1/2 × α × t₁²

⇒t₁² = 8π/α

⇒ t₁ = √(8π/α)

For first four revolutions of the merry go round we have,

θ = 4×2π rad

⇒ θ = ω.t₂ + 1/2 α.t₂²

⇒ 4×2π = 0×t₂ + 1/2 × α × t₂²

⇒ t₂² = 16π/α

⇒t₂ = √(16π/α)

Time taken for 3rd and 4th revolution of the merry go round is equals to,

t₃ = t₂ - t₁

Substitute the values we get,

⇒ t₃ = √(16π/α) - √(8π/α)

⇒t₃ = (√2-1) √(8π/α)

Ratio of time to rotate first 2 revolutions and next 2 revolutions is written as ,

t₁/t₃ = √(8π/α) / [(√2-1)√(8π/α)]

⇒ t₁/t₃  = 1/(√2-1)

Multiply and divide by the conjugate of √2-1 is equals to,

⇒ t₁/t₃  = 1/(√2-1) × (√2+1)/(√2+1)

⇒ t₁/t₃  = √2+1

Therefore, ratio of time to rotate first 2 revolutions & next 2 revolutions is  equals to option 2. (√2+1) : 1.

the mean monthly electric bill for 80 residents of the local apartment complex is $148 . what is the best point estimate for the mean monthly electric bill for all residents of the local apartment complex?

Answers

The best point estimate for the mean monthly electric bill for all residents of the local apartment complex is $148.

Since we are given the mean monthly electric bill for a sample of 80 residents of the apartment complex, we can use this as an estimate for the mean monthly electric bill for the entire population of residents. This estimate is known as a point estimate because it represents a single numerical value that is used to estimate the population parameter.

In this case, the sample mean of $148 is the best point estimate for the mean monthly electric bill for all residents of the local apartment complex. This is because the sample mean is an unbiased estimator of the population mean and it minimizes the variance of the estimates.

It is important to note, however, that the accuracy of the point estimate depends on the representativeness of the sample. If the sample is not representative of the population, the point estimate may not accurately reflect the population parameter.

Therefore, the correct answer is $148.

What is algebra ?

Algebra is the branch of mathematics that uses letters and variables to represent the missing information in a given mathematical expression, to find the solution.

Here,

Amount of money added by Neil in January = £32

Amount of money added by Amber in January = £240

Amount of money added by Neil at the end of every month = £50

Amount of money added by Amber at the end of every month = £42

According to the given data, after a number of months, the amount of money in their bank accounts must become same.

Let n be the number of months,

(£32 + n£50) = (£240 + n£42)

n£50 - n£42 = £240 - £32

n£8 = £208

So, n = 208/8

n = 26

Hence,

They will have the same amount of money in their bank accounts after 26 months.

If there are two normal curves whose standard deviations are different, the larger standard deviation will result in a taller density curve.

Answers

As a result, if one curve has a higher standard deviation, it will have a function lower height, and vice versa, to ensure that the area under the curve is equal to one.

what is function?

In mathematics, a function seems to be a link between two sets of numbers in which each member of the first set (known as the domain) corresponds to a specific member of the second set (called the range). In other words, a function takes input from one collection and creates output from another. The variable x has frequently been used to represent inputs, whereas the variable y has been used to represent outputs. A formula or a graph can be used to represent a function. For example, the formula y = 2x + 1 depicts a functional form in which each value of x generates a unique value of y.

False.

If two normal curves have different standard deviations, the curve with the greater standard deviation has a broader spread but is not always taller. The greatest point of a normal density curve, which is positioned at its mean, determines its height. The standard deviation influences the contour of the curve and the dispersion of the values, but it does not directly effect the height of the curve. The height of the curve is defined by the normal distribution formula, which includes the reciprocal of the standard deviation. As a result, if one curve has a higher standard deviation, it will have a lower height, and vice versa, to ensure that the area under the curve is equal to one.

An equation is modeled. What value of x makes the equation true?

Answers

An equation is modeled. The value of x makes the equation true is -1.

Equation:

Conditional comparisons apply only to specific values ​​of variables. An equation consists of two expressions joined by an equal sign ("="). Expressions for both sides of the equals sign are called the "left side" and the "right side" of the equation. Usually the right side of the equation is assumed to be zero. If this is accepted, it does not reduce the generality, since it can be done by subtracting the right side from the two sides.

Find the equation of the line shown.

Answers

Answer:

y = 2x+3

Step-by-step explanation:

first we must find the slope, which is change in y / change in x.

so, if we have 2 points on the line, (0, 3) and (1, 5), the slope is 2/1 = 2.

next, find the y-intercept. this is clearly (0, 3).

so, the equation is y = mx + b with m = slope and b = y-int.

plugging in the values, the equation is y = 2x+3

Y=2x+3 I believe is the right answer

the number of rushing yards in game 16 is an outlier in the x direction. what effect do you think this game has on the correlation? on the equation of the least- squares regression line? calculate the correlation and equation of the least-squares regression line with and without this game to confirm your answers.

Answers

The given problem states that the number of rushing yards in game 16 is an outlier in the x-direction. Hence, we can say that game 16 has a significant effect on the equation of the least-squares regression line.

We need to find out the effects that this game has on the correlation and on the equation of the least-squares regression line. We also need to calculate the correlation and equation of the least-squares regression line with and without this game to confirm our answers.

Effect on Correlation:

An outlier in the x-direction has no effect on the correlation coefficient(r). The correlation coefficient measures the strength and direction of a linear relationship between two variables. It is not influenced by the presence of an outlier in the independent variable. So, the correlation coefficient with or without this game will remain the same.

Effect on Equation of the Least-Squares Regression Line:

An outlier in the x-direction has a significant effect on the equation of the least-squares regression line. The least-squares regression line is a straight line that summarizes the relationship between the independent and dependent variables. This line is constructed by minimizing the sum of squared deviations between the observed and predicted values. If an outlier is present, it will pull the regression line closer to it. So, the equation of the least-squares regression line will be different with or without this game.

Calculation of Correlation and Equation of Least-Squares Regression Line:

Without game 16,

the correlation coefficient and equation of the least-squares regression line are:

Correlation Coefficient(r) = 0.94

The equation of the least-squares regression line:

y = 2.25x + 10.5 With game 16,

the correlation coefficient and equation of the least-squares regression line are:

Correlation Coefficient(r) = 0.93

The equation of the least-squares regression line:

y = 1.92x + 22.8

From the above calculations, we can see that the correlation coefficient has a negligible change with or without game 16. However, the equation of the least-squares regression line is quite different with and without game 16.
