With wait times of 12 and 15 minutes for the most popular ride, bimodal distribution is the best way to describe the form of the data for

The line plot shows the wait time in line for a ride at a local fair, with the number of dots above each time interval representing the frequency of wait times falling in that interval.

The data is not symmetric, according to the provided line plot, which shows that there are more dots above 12 and 15 minutes than at other time intervals. This shows that the data is not normally distributed, and that the symmetric distribution assumption is consequently incorrect.

The claim that "the wait times were less than 13 minutes for all the rides" is untrue is further supported by the absence of dots over time intervals of less than 10 minutes. While there are dots above time intervals less than and equal to 13 minutes, it is equally untrue to say that "the wait times were over 13 minutes for all the rides."

Because there are two peaks in the distribution with wait times of 12 and 15 minutes for the most popular ride, bimodal distribution is the best way to describe the form of the data. This may indicate the existence of two popular rides with distinct wait times, or it may indicate that the popularity of some rides fluctuated over time, resulting in a bimodal distribution.

Answer:

shortened height = h(1 - tan(20))

Step-by-step explanation:

To solve this problem, we need to use trigonometry to find the height that the airplane reaches at a 20° angle, and then subtract this height from the height of the cell tower to determine how short it needs to be.

Let's assume that the cell tower has a height of "h", and that the airplane takes off at a 20° angle. We can use trigonometry to find the height "x" that the airplane reaches above the ground:

tan(20) = x / h

Multiplying both sides by "h", we get:

x = h * tan(20)

So the airplane reaches a height of "x" above the ground. To find how short the cell tower needs to be, we simply subtract this height from the original height of the tower "h":

shortened height = h - x

Substituting the expression we found for "x", we get:

shortened height = h - h * tan(20)

Simplifying, we get:

shortened height = h(1 - tan(20))

So, the cell tower needs to be shortened by "h(1 - tan(20))" to ensure that the airplane can take off safely at a 20° angle.

The customer margin on sales to Interstate Trucking for the year is $33,581.

Indirect costs are expenses that cannot be directly linked to a specific product or service. Instead, they are costs that are incurred for the general operation of a business and are shared among different products or services produced by the business.

In the given question,

To calculate the customer margin on sales to Interstate Trucking, we need to use the activity-based costing system to allocate the indirect costs to the order and then subtract the total costs from the sales revenue. Here are the steps to follow:

Calculate the total indirect costs for the order:

Batch processing cost = Number of batches x Batch processing activity rate

Batch processing cost = 3 x $95 = $285

Order processing cost = Number of orders x Order processing activity rate

Order processing cost = 1 x $285 = $285

Customer service cost = Number of customers x Customer service activity rate

Customer service cost = 1 x $2,624 = $2,624

Total indirect costs = Supporting direct labor cost + Batch processing cost + Order processing cost + Customer service cost

Total indirect costs = Number of direct labor-hours x Supporting direct labor activity rate + Batch processing cost + Order processing cost + Customer service cost

Total indirect costs = 0.7 x 2,200 x $8 + $285 + $285 + $2,624

Total indirect costs = $20,289

Calculate the total costs for the order:

Total costs = Direct materials cost + Direct labor cost + Total indirect costs

Total costs = $110 x 2,200 + $13.70 x 2,200 + $20,289

Total costs = $147,739

Calculate the customer margin on sales:

Customer margin = Sales revenue - Total costs

Customer margin = $141.60 x 2,200 - $147,739

Customer margin = $181,320 - $147,739

Customer margin = $33,581

Therefore, the customer margin on sales to Interstate Trucking for the year is $33,581.

Answer:

a) 0.0281

b) 0.6924

c) 0.3081

Step-by-step explanation:

Probability that one of those sampled saying that Roosevelt was the best president since World War II = 345/2055 = 0.17

Probability that one of those sampled don't mention Roosevelt = (2055 - 345)/2055 = 1710/2055 = 0.83

a) The probability that both adults picked say Franklin Roosevelt was the best president since World War II = (345/2055) × (344/2054) = 0.0281

b) The probability that neither of the two adults say Franklin Roosevelt was the best president since World War II = (1710/2055) × (1709/2054) = 0.6924

c) The probability that at least one of the two adults says Franklin Roosevelt was the best president since World War II = Probability that one of the two adults mention Roosevelt + Probability that the two adults mention Roosevelt

Probability that one of the adults mention Roosevelt = [(345/2055) × (1710/2054)] + [(1710/2055) × (345/2054)] = 0.280

Probability that two of the adults mention Roosevelt has been done in (a) and it is equal to 0.0281

Probability that at least one of the two adults says Franklin Roosevelt was the best president since World War II = 0.280 + 0.0281 = 0.3081

Answer:

The best measure of center for the data shown is the median, and its value is 11.

Step-by-step explanation:

In statistics, measures of central tendency are used to summarize a set of data and provide a single value that represents the center or typical value of the data. The three commonly used measures of central tendency are the mean, median, and mode.

The mean is calculated by adding up all the values in the data set and dividing by the total number of values. The mean is affected by outliers and can be heavily skewed by extreme values.

The median is the middle value of the data set when the values are arranged in order. It is not affected by extreme values and is a more robust measure of central tendency compared to the mean.

In the given box plot, the distribution appears relatively symmetric, with the box extending from 9 to 15 on the number line and the median line located at 11, which is the middle value of the box. Therefore, the best measure of center for the data shown is the median, and its value is 11.

The best measure of the center for the data shown is the median, and its value is 11 thus the correct option is  C.

The mean is the average value which can be calculated by dividing the sum of observations by the number of observations

Mean = Sum of observations/the number of observations

Median represents the middle value of the given data when arranged in a particular order.

In statistics, the measures of central tendency are used to summarize a set of data and provide a single value that shows the center or typical value of the data. Also, it is known that three commonly used measures of central tendency are the mean, median, and mode.

With mean=2.2, the training program was effective in increasing the production rates.

What is mean?

In mathematics, the mean represents the average value of a dataset. It is calculated by summing all the values in a dataset and dividing by the total number of values. The mean is often used as a standard measure of the central location of a dataset

Now,

The hypotheses for this problem are:

Null hypothesis (H0): The training program did not have any effect on the production rates. In other words, the mean difference in production rates (d) is equal to zero.

Alternative hypothesis (Ha): The training program was effective in increasing the production rates. In other words, the mean difference in production rates (d) is greater than zero.

To compute the test statistic, we first need to find the sample mean and standard deviation of the differences:

d = After - Before

Worker Before After   d

1            6           9         3

2           10          12        2

3           9            10       1

4           8             11       3

5           7            9        2

The sample mean of the differences is:

mean(d) = (3+2+1+3+2)/5 = 2.2

The sample standard deviation of the differences is:

s = √(sum((d - mean(d))²)/(n-1)) = √((1.04)/4) = 0.57

The test statistic for testing the null hypothesis is:

t = (mean(d) - 0)/(√(n)) = (2.2 - 0)/(0.57/√(5)) = 6.07

Using a t-distribution with n-1 = 4 degrees of freedom and a significance level of 0.05, the critical value is 2.776.

Since the calculated t-value (6.07) is greater than the critical value (2.776), we reject the null hypothesis and conclude that the training program was effective in increasing the production rates.

If the radius of the pastry stamp Petra uses to stamp circles in the dough for the donuts is 4.25 inches, then the diameter is 2 * 4.25 = 8.5 inches. The area of each donut can be calculated using the formula for the area of a circle:

Area of a circle = π * radius^2

So, the area of each donut is:

π * (4.25)^2 = 56.75π square inches (rounded to two decimal places)

If the radius of the pastry stamp Petra uses to stamp out circles for the donut holes is 0.4 inches, then the diameter is 2 * 0.4 = 0.8 inches. The area of each donut hole can be calculated using the same formula:

Area of a circle = π * radius^2

So, the area of each donut hole is:

π * (0.4)^2 = 0.16π square inches (rounded to two decimal places)

According to the given information, the cyclists will meet after x hours of riding, and the distance from the orchard where they meet is given by either A(x) or B(x)

What is speed?

Speed is defined as the distance traveled by an object in a given amount of time. Speed is a scalar quantity, meaning that it has magnitude but no direction.

Mathematically, speed is calculated as follows:

speed = distance/time

where "distance" is the distance traveled by the object, and "time" is the time it takes for the object to travel that distance.

Let's assume that the distance function for cyclist A is given by: A(x) = ax + b, where a and b are constants that depend on the cyclist's speed and initial distance from the orchard, respectively.

Similarly, let's assume that the distance function for cyclist B is given by: B(x) = cx + d, where c and d are constants that depend on the cyclist's speed and initial distance from the orchard, respectively.

Since both cyclists left home at the same time, we know that their initial distance from the orchard must be the same. Therefore, we can set b = d and rewrite the distance functions as:

A(x) = ax + b

B(x) = cx + b

The cyclists will meet when their distances from the orchard are equal, so we can set A(x) = B(x) and solve for x:

ax + b = cx + b

ax - cx = b - b

x(a-c) = 0

Since x cannot be zero (they are riding for some positive amount of time), we know that a - c must be zero, which means that their speeds are equal:

a - c = 0

a = c

Therefore, we know that the cyclists are traveling at the same speed. To find the meeting point, we can set A(x) = B(x) = D, where D is the distance from the orchard where they meet, and solve for x:

ax + b = Dx

cx + b = Dx

ax + b = cx + b

ax - cx = 0

x(a-c) = 0

Since a = c, we can simplify this equation to:

x = 0 or x = D/(a-c)

Since we know that x cannot be zero (they left home at the same time and met later), we can conclude that:

x = D/(a-c)

Therefore, the cyclists will meet after x hours of riding, where x is given by the above formula, and the distance from the orchard where they meet is given by either A(x) or B(x) (they are equal at the meeting point).

What is the Law of Sines?

The Law of Sines is a mathematical formula used to relate the side lengths and angles of any triangle. It states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all three sides of the triangle.

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

To find the length of side z in triangle XYZ, we can use the Law of Sines, which states:

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

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

In this case, we know the length of side x, and the measures of angles Y and Z.

We want to find the length of side z. So, we can use the Law of Sines as follows:

z/sin(180° - 141° - 25°) = 830/sin(141°)

z/sin(14°) = 830/sin(141°)

Cross-multiplying:

z = (830*sin(14°))/sin(141°)

z ≈ 261.8 cm

Therefore, the length of side z to the nearest tenth of a centimeter is approximately 261.8 cm.

What is distance?

Distance is a measurement of how far apart two objects or points are, either numerically or rarely qualitatively. Distance can relate to a physical length in physics or to an estimate based on other factors in everyday language.

To find the distance made good, we need to calculate the total displacement of the ship. This can be found using the Pythagorean theorem, which states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides.

In this case, the 120 nm southward and 230 nm westward movements of the ship form the legs of a right triangle, and the hypotenuse represents the total displacement. Using the Pythagorean theorem, we get:

Total displacement = √((120²) + (230²)) nm

Question 4:

To factor the expression. [tex]2x^5+4x^3-6x^2-12[/tex], we can first take out a common factor of 2 from all the terms:

[tex]2(x^5+2x^3-3x^2-6)[/tex]

Next, we can factor the expression in the parentheses by grouping the first two terms and the last two terms:

[tex]2(x^5+2x^3-3x^2-6) = 2(x^5-3x^2) + 2(2x^3-6)[/tex]

[tex]= 2x^2(x^3-3) + 4(x^3-3)= (2x^2+4)(x^3-3)[/tex]

Therefore, the factored form of the expression[tex]2x^5+4x^3-6x^2-12 is (2x^2+4)(x^3-3).[/tex]

Question 5:

To factor the expression [tex]3x^7-8x^6-9x^5+24x^4[/tex], we can first take out a common factor of [tex]3x^4[/tex] from all the terms:

[tex]3x^4(x^3-8x^2-3x+8)[/tex]

Next, we can factor the expression in the parentheses by grouping the first two terms and the last two terms:

[tex]3x^4(x^3-8x^2-3x+8) = 3x^4(x^2(x-8)-1(x-8))= 3x^4(x-1)(x-8)(x^2+1)[/tex]

Therefore, the factored form of the expression[tex]3x^7-8x^6-9x^5+24x^4 is 3x^4(x-1)(x-8)(x^2+1).[/tex]

Question 6:

To factor the expression. [tex]-5x^3+10x^2-3x+6[/tex], we can first take out a common factor of -1 from all the terms:

[tex]-1(5x^3-10x^2+3x-6)[/tex]

Next, we can factor the expression in the parentheses by grouping the first two terms and the last two terms:

[tex]-1(5x^3-10x^2+3x-6) = -1(5x^2(x-2)+3(x-2))= -(5x^2+3)(x-2)[/tex]
