Step-by-step explanation:

The equation of the regression line is: y = 1.5 + 0.95x

To find the equation of the regression line, we can use the formulas:

b = [n(Σxy) - (Σx)(Σy)] / [n(Σx²) - (Σx)²]

a = [(Σy)(Σx²) - (Σx)(Σxy)] / [n(Σx²) - (Σx)²]

Given the following data:

n = 4

Σx = 20

Σy = 25

Σxy = 144

Σx² = 120

Let's calculate the values step by step:

b = [4(144) - (20)(25)] / [4(120) - (20)²]

  = (576 - 500) / (480 - 400)

  = 76 / 80

  = 0.95

a = [(25)(120) - (20)(144)] / [4(120) - (20)²]

  = (3000 - 2880) / (480 - 400)

  = 120 / 80

  = 1.5

Therefore, the equation of the regression line is:

y = 1.5 + 0.95x

The correct option to the sentence "The percentage of people who have an IQ between 70 and 130 ?" is:

b. 95%.

To solve for the percentage of people who have an IQ between 70 and 130, we will have to use the standard deviation and the mean IQ.

It is given that: Mean = 100, Standard deviation = 15

Now we will use these values to find the percentage of people who have an IQ between 70 and 130.

The first step to this process is to standardize the IQ scores by converting them to Z-scores.

The formula for Z-score is:

Z = (X - µ) / σ, where X represents the IQ score, µ represents the mean IQ, and σ represents the standard deviation.

IQ score of 70:

Z = (70 - 100) / 15

Z = -2

IQ score of 130:

Z = (130 - 100) / 15

Z = 2

Now that we have the Z-scores for IQ scores of 70 and 130, we can find the percentage of people who have an IQ between these two scores. We will use the Z-table to do this. The Z-table provides the area under the standard normal distribution curve for a given Z-score.

From the Z-table, we can find that the area under the curve between Z = -2 and Z = 2 is approximately 0.9545. This means that approximately 95.45% of people have an IQ between 70 and 130.

Therefore, the correct option is: b. 95%.

The value of the exterior angle (x) in a regular heptagon is approximately 51.43 degrees.

Given is a regular heptagon with one of the exterior angle be x we need to find the value of x

To find the value of the exterior angle of a regular heptagon, we can use the formula:

Exterior Angle = 360 degrees / Number of Sides

In this case, the heptagon has seven sides, so we can substitute the values into the formula:

Exterior Angle = 360 degrees / 7

Exterior Angle ≈ 51.43 degrees

To perform a statistically valid comparison of the two loader options, we can use simulation and common random numbers. We simulate the process over a 40-hour time horizon and compare the mean system response times for each loader option.

For the two slower loaders, we generate random numbers uniformly distributed between 1 and 27 minutes to represent the time taken to fill a truck. For the fast loader, we generate random numbers uniformly distributed between 1 and 19 minutes.

By simulating the process multiple times using the same set of random numbers (common random numbers), we can compare the mean system response times between the two loader options.

After running the simulation, we calculate the mean system response time for each loader option by averaging the response times of all trucks. We repeat the simulation multiple times (e.g., 100 or more) to obtain reliable estimates of the mean system response times.

Once we have the mean system response times for each loader option from multiple simulation runs, we can perform a statistical analysis to determine if there is a significant difference between the two options.

This analysis can be done using a suitable statistical test, such as a t-test or confidence interval analysis, depending on the distribution of the response time data and the assumptions made.

The statistical analysis will provide insights into whether the fast loader option significantly reduces the mean system response time compared to the slower loader options. A lower mean system response time would indicate better performance in terms of faster truck processing.

The optimal solution to minimize cost while meeting the building code is to use 0 Sitka spruce planks and 150 basswood planks.

To minimize the cost while meeting the building code, let's assume we use x Sitka spruce planks and y basswood planks.

We want to minimize the cost, so our objective function is the cost of the planks. The cost is given by:

Cost = 3.25x + 3.75y

We also have the constraint that the total weight of the planks must be between 600 and 900 pounds:

3x + 4y ≥ 600

3x + 4y ≤ 900

To solve this optimization problem, we can use linear programming. We'll use the Simplex method to find the optimal solution.

Let's rewrite the constraints in standard form:

-3x - 4y ≤ -600

3x + 4y ≤ 900

Now we have the following system of equations:

-3x - 4y ≤ -600

3x + 4y ≤ 900

The feasible region is a quadrilateral with vertices at (0, 150), (0, 225), (300, 150), and (225, 0).

To minimize the cost, we need to find the corner point of the feasible region that lies on the cost line, which is given by 3.25x + 3.75y.

Let's evaluate the cost at each corner point:

Cost at (0, 150) = 3.25(0) + 3.75(150) = 562.50

Cost at (0, 225) = 3.25(0) + 3.75(225) = 843.75

Cost at (300, 150) = 3.25(300) + 3.75(150) = 1500.00

Cost at (225, 0) = 3.25(225) + 3.75(0) = 731.25

From the evaluations, we can see that the minimum cost is achieved at (0, 150), which means we should use 0 Sitka spruce planks and 150 basswood planks.

a) The x-intercepts of p(x) are x = 3 and x = -4/3.  b) The y-intercept of p(x) is y = -12.

a) To find the x-intercepts, we set p(x) = 0 and solve for x:

x + 3x² - 4x - 12 = 0

Simplifying the equation, we get:

3x² - 3x - 12 = 0

Factoring, we have:

(x - 3)(3x + 4) = 0

Setting each factor equal to zero, we find the x-intercepts:

x = 3 and x = -4/3

b) The y-intercept is the value of p(0), so we substitute x = 0 into the equation:

p(0) = 0 + 3(0)² - 4(0) - 12 = -12

Therefore, the y-intercept is -12.

c) To sketch the graph, we plot the x-intercepts (x = 3 and x = -4/3) and the y-intercept (y = -12) on a coordinate plane.

Answer:

Least Likely: Arrow lands on a section labeled with an odd number.

_____: Arrow lands on a section labeled with the number 1.

Most Likely: Arrow lands on a section labeled with a number less than 4.

Step-by-step explanation:

The spinner:

There are 8 sections, 4 labeled with the number 1, 2 labeled with the number 3, 1 labeled with the number 3, and 1 labeled with the number 4.

Probabilities of the spinner:

The options:

A - Arrow lands on a section labeled with an odd number.

B - Arrow lands on a section labeled with the number 1.

C - Arrow lands on a section labeled with a number less than 4.

The probabilities are:

P(0 < z < 1.96) = 0.4750

P(-1.23 < z < 0) = 0.3907

P(z > 0.82) = 0.2061

P(z < -1.77) = 0.0384

P(-0.20 < z < 1.56) = 0.5199

P(1.12 < z < 1.43) =0.0550

P(z > -1.43) = 0.9236

To locate the chances of the usage of the same old ordinary distribution, we will use a well-known normal desk or a calculator. Here are the calculations for the given possibilities:

P(0 < z < 1.96):

Using the standard everyday desk, the place to the left of one.Ninety-six is 0.9750, and the vicinity to the left of zero is 0.5000. Therefore, the chance between zero and 1.96 is:

P(0 < z < 1.96) = 0.9750 - 0.5000 = 0.4750

P(-1.23 < z < 0):

Using the usual ordinary table, the vicinity to the left of -1.23 is 0.1093, and the area to the left of zero is zero.5000. Therefore, the possibility between -1.23 and 0 is:

P(-1.23 < z < 0) = 0.5000 - 0.1093 = 0.3907

P(z > 0.82):

Using the standard everyday table, the region to the left of zero.82 is zero.7939. Therefore, the possibility of z being extra than 0.82 is:

P(z > 0.82) = 1 - 0.7939 = 0.2061

P(z < -1.77):

Using the same old regular desk, the vicinity to the left of -1.Seventy-seven is zero.0384. Therefore, the chance of z being much less than -1.77 is:

P(z < -1.77) = 0.0384

P(-zero.20 < z < 1.56):

Using the standard ordinary desk, the area to the left of -0.20 is 0.4207, and the area to the left of 1.56 is 0.9406. Therefore, the opportunity between -0.20 and 1. Fifty-six is:

P(-0.20 < z < 1.56) = 0.9406 - 0.4207 = 0.5199

P(1.12 < z < 1.43):

Using the standard regular desk, the place to the left of 1.12 is 0.8686, and the location to the left of one. Forty-three is zero.9236. Therefore, the opportunity between 1.12 and 1. Forty-three is:

P(1.12 < z < 1.43) = 0.9236 - 0.8686 = 0.0550

P(z > -1.43):

Using the same old normal desk, the location to the left of -1.43 is zero.0764. Therefore, the possibility of z being greater than -1. Forty-three is:

P(z > -1.43) = 1 - 0.0764 = 0.9236
