The mean of the test is 20.

To determine the mean of the test, we need to use the information provided about the scores falling above the mean in terms of standard deviations.

Let's denote the mean of the test as μ, and the standard deviation as σ.

We are given that a score of 29 falls three standard deviations above the mean, so we can write this as:

29 = μ + 3σ

Similarly, we are told that a score of 23 falls one standard deviation above the mean, which can be expressed as:

23 = μ + σ

Now we have a system of two equations with two variables (μ and σ). We can solve this system of equations to find the values of μ and σ.

From the second equation, we can isolate μ:

μ = 23 - σ

Substituting this value into the first equation, we have:

29 = (23 - σ) + 3σ

Simplifying the equation, we get:

29 = 23 + 2σ

2σ = 29 - 23

2σ = 6

σ = 3

Substituting the value of σ back into the second equation, we find:

μ = 23 - 3

μ = 20

Answer:

Step-by-step explanation:

Based on the information provided, the residual plot makes sense based on the scatter plot.

In the given scatter plot, the points are plotted with horsepower on the x-axis and observed MPG (miles per gallon) on the y-axis. The scatter plot shows the relationship between horsepower and MPG for the motorcycles.

The residual plot, on the other hand, shows the differences between the observed MPG values and the predicted MPG values based on the regression line or model. Residuals represent the vertical distances between the observed data points and the regression line.

Looking at the residual plot, we can see that the residuals are scattered randomly around the zero line. Some residuals are positive, while others are negative, indicating that the observed MPG values deviate both above and below the predicted MPG values.

Given this information, option A is the correct answer: "The random residual plot makes sense because the scatter plot appears to have a linear relationship." The scatter plot does not necessarily suggest a positive or negative relationship between horsepower and MPG. It simply shows the general trend or pattern. The random distribution of residuals in the residual plot indicates that the regression model is capturing the relationship adequately, and the variations or deviations from the regression line are random, which is expected in a good regression model.

The residual plot created by Jorge does make sense as it reflects the negative relationship between horsepower and miles per gallon present in the original scatter plot. As the horsepower increases, the miles per gallon decreases which is depicted accurately in the residual plot made.

The best answer for this is B. The random residual plot makes sense because the scatter plot appears to have a negative relationship. A residual plot is a graph that is used to examine the goodness of fit in regression and ANOVA analysis. It is the differences between the observed and predicted values of data. The points in a residual plot are randomly dispersed around a horizontal axis if the corresponding regression model is appropriate for the data.

In this case, the scatter plot demonstrates a negative relationship between the horsepower of motorcycles and miles per gallon. As the horsepower increases, the miles per gallon decrease. This negative relationship is reflected in the pattern of residuals, which fluctuates around the zero line on the y-axis of the residual plot. Consequently, the random distribution of residuals on Jorge's plot does make sense given the scatter plot data.

The probability that exactly 9 of the chosen apartments are on the ground floor is approximately 0.3088 or 30.88%.

The number of favourable outcomes and the total number of possible outcomes must be determined in order to determine the likelihood that precisely 9 of the chosen flats are on the ground floor.

The total number of outcomes is the number of ways to select 14 of the 17 available flats. You can compute this using the following combination formula:

C(n, r) = (n!/(n-r)!)

In this instance, the total number of flats is 17 and the number of units that were selected is 14. In other words, C(17, 14) = 17! / (14!(17-14)!) = 17! / (14!* 3!) = (17 * 16 * 15) / (3 * 2 * 1) = 680.

The solution to the given system of equations is x = 0 and y = 5.

To find the solution of the system of equations:

Let's write the given system of equations:

Equation 1: 4x + 3y = 15

Equation 2: x - 3y = -15

We can solve this system using the method of substitution or elimination. Let's use the method of elimination in this case.

To eliminate the variable 'y', let's multiply Equation 2 by 3:

Equation 2: 3(x - 3y) = 3(-15)

3x - 9y = -45

Now, we can add Equation 1 and Equation 2 together to eliminate the 'y' variable:

(4x + 3y) + (3x - 9y) = 15 + (-45)

4x + 3x + 3y - 9y = -30

7x - 6y = -30

Rearrange the equation to isolate 'x':

7x - 6y = -30

7x = 6y - 30

x = (6y - 30)/7

Substitute the expression for 'x' into either Equation 1 or Equation 2. Let's substitute it into Equation 1:

4x + 3y = 15

4((6y - 30)/7) + 3y = 15

(24y - 120)/7 + 3y = 15

Simplify the equation and solve for 'y':

(24y - 120 + 21y)/7 = 15

45y - 120 = 105

45y = 225

y = 5

Substitute the value of 'y' back into the expression for 'x':

x = (6y - 30)/7

x = (6(5) - 30)/7

x = 0

The solution to the system of equations is x = 0 and y = 5.

The Range of the total number of travelers constraint (x + y ≥ 100), it is feasible.the maximum number of first-class tickets they can sell is 100 (at the point (100, 80)).The maximum profit they can achieve is $38,500 when they sell 100 first-class tickets and 80 coach tickets.

(a) Let's create a system of constraints based on the given situation:

1. First-class ticket constraint: First-class ticket sales must be at least 20.

  x ≥ 20

2. Coach ticket constraint: Coach ticket sales must be at least 45.

  y ≥ 45

3. Total number of travelers constraint: The plane must have at least 100 travelers.

  x + y ≥ 100

4. Maximum capacity constraint: The plane has a maximum capacity of 180 travelers.

  x + y ≤ 180

(b) To graph the system of constraints, we plot the inequalities on a coordinate plane:

The first-class ticket constraint (x ≥ 20) is a vertical line passing through (20, 0).

The coach ticket constraint (y ≥ 45) is a horizontal line passing through (0, 45).

The total number of travelers constraint (x + y ≥ 100) is a line passing through (100, 0) and (0, 100).

The maximum capacity constraint (x + y ≤ 180) is a line passing through (180, 0) and (0, 180).

(c) The feasible region is the shaded area where all constraints are satisfied.

The corner points of the feasible region are (20, 45), (20, 100), (80, 100), and (100, 80).

(d) To determine if it is feasible to sell 150 coach tickets and 25 first-class tickets, we check if these values satisfy the constraints.

150 coach tickets and 25 first-class tickets would give us a total of 175 travelers (150 + 25). Since this is within the range of the total number of travelers constraint (x + y ≥ 100), it is feasible.

(e) From the graph, we can observe that the maximum number of coach tickets they can sell is 80 (at the point (80, 100)), and the maximum number of first-class tickets they can sell is 100 (at the point (100, 80)).

(f) To maximize profits, we need to determine the corner point within the feasible region that gives the highest profit. We calculate the profit for each corner point and select the maximum.

For (20, 45): Profit = (225 * 45) + (200 * 20) = 10,125 + 4,000 = $14,125

For (20, 100): Profit = (225 * 100) + (200 * 20) = 22,500 + 4,000 = $26,500

For (80, 100): Profit = (225 * 100) + (200 * 80) = 22,500 + 16,000 = $38,500

For (100, 80): Profit = (225 * 80) + (200 * 100) = 18,000 + 20,000 = $38,000

The maximum profit they can achieve is $38,500 when they sell 100 first-class tickets and 80 coach tickets.

(g) The minimum profit they can achieve from the flight is $0 if they don't sell any tickets or if the number of travelers is below the minimum required for profitability.

To find the mean of the population based on the given data, we need to calculate the sum of all the responses and divide it by the total number of campers.

The given responses are: 3, 2, 0, 1, 0, 2, 3, 4, 1, 2, 2, 1

Sum of the responses = 3 + 2 + 0 + 1 + 0 + 2 + 3 + 4 + 1 + 2 + 2 + 1 = 21

Total number of campers = 48

Mean of the population = Sum of the responses / Total number of campers = 21 / 48 ≈ 0.4375

Rounded to the nearest unit, the mean number of siblings for the population is 0.

To find mean, first add everything together.

3 + 2 + 0 + 1 + 0 + 2 + 3 + 4 + 1 + 2 + 2 + 1

This equals to 21.

Then, divide the total by the amount of campers there are.

The total amount paid in the first month would be $32 for the minimum payment plus $9.20 for the interest, totaling $41.20.

If you have a credit card with an annual percentage rate (APR) of 30% and a minimum payment requirement of 8% of the balance, and you have a balance of $400 on the credit card, you decide to stop charging and pay it off by making the minimum monthly payment each month, here's how it would work:

The minimum monthly payment would be 8% of the balance, which is 0.08 x $400 = $32.

Each month, you would make a payment of $32 towards your credit card balance. However, keep in mind that the interest will continue to accrue on the remaining balance.

Since the APR is 30%, the monthly interest rate would be 30% / 12 = 2.5%.

To calculate the interest charged each month, you multiply the remaining balance by the monthly interest rate. For example, after the first payment, the remaining balance is $400 - $32 = $368. The interest charged for that month would be 2.5% x $368 = $9.20.

Therefore, the total amount paid in the first month would be $32 for the minimum payment plus $9.20 for the interest, totaling $41.20.

Each month, you would continue making the minimum payment, and the interest charged would be based on the remaining balance. The process would continue until the balance is paid off in full.

There are a total of 40 students in the class after these changes.

Let's use j to represent the number of juniors in the class and s to represent the number of seniors in the class. We know that the ratio of juniors to seniors is 3:2, so we can write:

j/s = 3/2

Multiplying both sides by 2s gives us:

j = (3/2)s

We also know that when six more juniors join and one senior drops, the ratio becomes 4:1, so we can write:

(j + 6) / (s - 1) = 4/1

Multiplying both sides by (s - 1) gives us:

j + 6 = 4(s - 1)

j + 6 = 4s - 4

Substituting j = (3/2)s into this equation gives:

(3/2)s + 6 = 4s - 4

s = 14Therefore, there are 14 seniors in the class. Substituting s = 14 into j = (3/2)s gives:

j = (3/2)(14) = 21

Before the changes, there were 21 juniors and 14 seniors in the class. After six more juniors join and one senior drops, there are:

21 + 6 = 27 juniors

14 - 1 = 13 seniors

The value of the variable x that helps us to find  the lengths of the triangle is: x = 3/2

We know that when we have an Isosceless triangle, that we have two equal sides and two equal base angles and as such we can easily see that the given triangle is an Isosceles Triangle.

We are given the two equal sides to be represented by the lengths:

(8x - 1) and (4x + 5)

Thus:

8x - 1 = 4x + 5

8x - 4x = 5 + 1

4x = 6

x = 6/4

x = 3/2

Thus, that is the value of x to solve for the lengths of the triangle.

In Container B, there are roughly 1.7643 kg of sand.

Compared to Container B, Container C had about 0.7057 kg less sand.

Let's say that Container B contains 'x' kilogrammes of sand.

The amount of sand in Container A is 2x kg since it has twice as much as Container B does.

The amount of sand in Container C grew by 20% after 15% of the sand from Container A and 20% of the sand from Container B were transferred there.

Let's figure out how much sand is in Container C:

Sand moved from Container A to Container C weighed 0.15 x 2 x kg.

The amount of sand moved from Container B to Container C is equal to 0.20 * x kg.

After the transfer, Container C now contains 20% more sand overall. Sand in Container C therefore contains 1.2 times as much as it did initially.

After the transfer, the total amount of sand in Container C is equal to 1.2 * (0.3x + 0.2x) = 1.2 * 0.5x = 0.6x kg.

Therefore, we can conclude that Container C held 2.47 kg more sand than Container A. Thus, we can construct the following equation:

0.6x - 2x = 2.47

Simplifying the equation:

-1.4x = 2.47

Dividing both sides by -1.4:

x = -2.47 / -1.4 ≈ 1.7643

So there is roughly 1.7643 kg of sand in Container B.

To determine the variation in sand content between Containers C and B:

Sand in Container C less Sand in Container B equals the difference.

Difference = 0.6x - x

Difference = -0.4x

Substituting the value of x:

Difference = -0.4 * 1.7643 ≈ -0.7057

Container C therefore contained around 0.7057 kg less sand than Container B.
