Answer:

M = (13, - 6 )

Step-by-step explanation:

The coordinates of the midpoint are the average of the x and y coordinates of the endpoints.

L (- 9, 4 ) , let M = (x, y ) , then

\(\frac{-9+x}{2}\) = 2 ( multiply both sides by 2 )

- 9 + x = 4 ( add 9 to both sides )

x = 13

and

\(\frac{4+y}{2}\) = - 1 ( multiply both sides by 2 )

4 + y = - 2 ( subtract 4 from both sides )

y = - 6

Then

coordinates of M = (13, - 6 )

Given: The base of a solid is the area enclosed by y = 3x2, x = 1, and y = 0.

We know that, when slices are made perpendicular to the x-axis, the cross-section of the solid is a semi-circle.

Given, the solid has base as the area enclosed by y = 3x2, x = 1, and y = 0.

The graph is as shown below: Here, the base is from x = 0 to x = 1.

The radius of semi-circle at any point x is given by r = y = 3x2

The area of semi-circle at any point x is given by A = (1/2) πr2 = (1/2) πy2 = (1/2) π(3x2)2 = (9/2) πx4.

The volume of the solid is given by the integral of the area of the semi-circle with respect to x from x = 0 to x = 1, which is as follows:

∫V dx = ∫(9/2) πx4 dx from x = 0 to x = 1V = [9π/10] [1^5 − 0^5] = 9π/10

Thus, the volume of the solid is 9π/10. Hence, this is the required answer.Note:Here, the cross-section of the solid is not the same for all x. The cross-section is a semi-circle, which is perpendicular to the x-axis and has a radius of 3x2.

Hence, we can compute the area of the cross-section by finding the area of the semi-circle with radius 3x2. The volume of the solid is the integral of the area of the cross-section with respect to x, from x = 0 to x = 1.

By dividing the figure in a rectangle and a circle, we will see that the area of the composited figure is equal to 149.25 square units.

The area will be the area of the rectangle plus the area of the semicircle.

We can see that the width of the rectangle is equal to the diameter of the semicircle, and the radius of the semicircle is 5 units, so its diameter is:

2*5 = 10 units.

Then the rectangle measures 11 units by 10 units, then its area is:

A = 10*11 = 110 square units.

In another hand, for a semicircle of radius R the area is:

A = 0.5*3.14*R^2

In this case we have R = 5, replacing that we get:

A = 0.5*3.14*5^2 = 39.25 square units.

Adding these two we get:

Area = 110 square units + 39.25 square units = 149.25 square units.

Ans - The random variable, x, represents the number of 1's showing when rolling 4 fair standard 9-sided dice , and The possible numerical values for x, in ascending order, are 0, 1, 2, 3, and 4.

When rolling a fair standard 9-sided die, the numbers that can appear are 1, 2, 3, 4, 5, 6, 7, 8, and 9. We want to determine how many 1's show up when rolling 4 dice.

Let's consider each possibility:

1. No 1's: This means that none of the 4 dice shows a 1. In this case, x would be 0.

2. One 1: One of the 4 dice shows a 1, while the other 3 dice show numbers other than 1. We can choose any of the 4 dice to be the one showing a 1, so there are 4 possibilities. In this case, x would be 1.

3. Two 1's: Two of the 4 dice show a 1, while the other 2 dice show numbers other than 1. We can choose any 2 dice to show a 1, so there are (4 choose 2) = 6 possibilities. In this case, x would be 2.

4. Three 1's: Three of the 4 dice show a 1, while the remaining die shows a number other than 1. We can choose any 3 dice to show a 1, so there are (4 choose 3) = 4 possibilities. In this case, x would be 3.

5. Four 1's: All 4 dice show a 1. There is only 1 possibility in this case. In this case, x would be 4.

The rate of change of temperature with respect to distance is given by dT/dd = 2T / d, where T is the temperature function and d is the distance function defined as the square root of the sum of squares of x and y.

To find the rate of change of temperature with respect to distance, we need to determine the distance function in terms of x and y. The distance function can be defined as the square root of the sum of squares of x and y, i.e., d = √(x² + y²).

We are given the temperature function T(x, y) = 1 + x² + y². To find the rate of change of temperature with respect to distance, we need to compute dT/dd, where dd represents the derivative of the distance function.

Using the chain rule, we can express dT/dd as follows:

dT/dd = ∂T/∂x * ∂x/∂d + ∂T/∂y * ∂y/∂d,

where ∂T/∂x and ∂T/∂y represent the partial derivatives of T(x, y) with respect to x and y, respectively.

Let's compute the partial derivatives:

∂T/∂x = 2x,

∂T/∂y = 2y.

To find ∂x/∂d and ∂y/∂d, we can differentiate the distance function with respect to x and y, respectively:

∂x/∂d = x/d,

∂y/∂d = y/d.

Now, substituting these values into the equation for dT/dd:

dT/dd = 2x * (x/d) + 2y * (y/d),

= (2x² + 2y²) / d,

= (2(x² + y²)) / d,

= 2T / d.

Therefore, the rate of change of temperature with respect to distance is given by dT/dd = 2T / d.

The distance between two trains is 224 miles.

The speed of one train is 75 miles per hour and the speed of the second train is 85 miles per hour.

The train is moving towards each other. So the relative speed of the train is,

So the distance between trains 224 miles is covered at the speed of 160 miles per hour.

Determine the time after which trains meet each other.

So two trains meet after 1.4 hours.

The exact solution of this equation involves solving a quadratic equation, which may not result in a simple integer value for x.

To find the point (x, y) on the function f(x) = 6 - 7x that is closest to the point (-10, -4), we need to minimize the distance between the two points.

The distance between two points (x1, y1) and (x2, y2) is given by the formula:

d = sqrt((x2 - x1)^2 + (y2 - y1)^2)

In this case, we want to minimize the distance between the point (-10, -4) and any point on the function f(x) = 6 - 7x. So we can set up the distance equation:

d = sqrt((-10 - x)^2 + (-4 - (6 - 7x))^2)

To find the point (x, y) that minimizes the distance, we can find the value of x that minimizes the distance equation. Let's differentiate the distance equation with respect to x and set it equal to zero to find the critical point:

d' = 0

Differentiating and simplifying the equation, we get:

(-10 - x) + (-4 - (6 - 7x))(-7) = 0

Solving this equation will give us the value of x at the closest point. Plugging this x-value into the function f(x) = 6 - 7x will give us the corresponding y-value.

A) Approx. 1067 is the required sample size to ensure 95% confidence that the sample proportion will not differ from the true proportion by more than 3%.

B) When the previous estimate is 65%, approx. 971 is the sample size needed to achieve 95% confidence that the sample proportion will not differ by more than 3% from the true proportion.

To determine the sample size needed for estimating the proportion of drivers exceeding the speed limit, we can use the formula for sample size calculation for proportions:

n = (Z² * p * (1 - p)) / E²

where:

n = the sample size.

Z = the Z-value associated with the confidence level of 95%.

p = the estimated proportion or previous estimate.

E = the maximum allowable error, which is 3% or 0.03.

We calculate as follows:

A. No previous estimate for p is available:

Here, we will assume p = 0.5 (maximum variance) since we don't have any prior information about the proportion. So, adding the values into the formula:

n = (Z² * p * (1 - p)) / E²

n = ((1.96)² * 0.5 * (1 - 0.5)) / 0.03²

n= (3.842 * 0.5 * (0.5))/0.03²

n = (1.9208*0.5)/0.0009

n ≈ 1067.11

Thus, to be 95% confident that the sample proportion will not differ from the true proportion by more than 3%, a sample size of approximately 1067 is required.

B. Supposing previous studies found that the sample percentage of drivers who exceeded the speed limit is 65%:

Here, we have a previous estimate of p = 0.65:

Putting the values into the formula:

n = (Z²* p * (1 - p)) / E²

n = ((1.96)² * 0.65 * (1 - 0.65)) / 0.03²

n= (3.842 * 0.65 *(0.35))/0.0009

n ≈ 971

Hence, with the previous estimate of 65%, a sample size of approximately 971 is necessary to be 95% confident that the sample proportion will not differ from the true proportion by more than 3%.
