The dimensions of the garden that minimize the cost are approximately 2.5 feet by 64.8 feet.

To find the dimensions of the garden that minimize the cost, we can use optimization techniques. Let's denote the length of the garden as L and the width as W.

The cost of the brick wall is $60 per foot, and since only one side is enclosed by the brick wall, the cost for that side is 60L. The cost of the metal fence is $40 per foot, and since three sides are enclosed by the metal fence, the cost for those sides is 40(2L + W).

The total cost C is the sum of the costs for the brick wall and the metal fence:

C = 60L + 40(2L + W)

Given that the area of the garden is 162 square feet, we have L * W = 162.

To minimize the cost, we can take the derivative of the cost function with respect to L and set it equal to zero:

dC/dL = 60 + 80 = 0

Solving for L, we find L = 2.5 feet.

Substituting L = 2.5 into the area equation, we get W = 162 / 2.5 = 64.8 feet.

Answer: Use a point-slope equation to find the amount he will raise if he completes the walk.

Step-by-step explanation:

We can start by using the point-slope equation:

y - y1 = m(x - x1)

where y is the amount James raises, x is the number of miles he walks, m is the rate at which he raises money per mile, and (x1, y1) is a point on the line.

We know that James raises $15 extra for every mile he walks, so m = 15. We also know that he has received $600 in fixed pledges, which is the amount he would raise if he walked 0 miles. So (0, 600) is a point on the line.

Using this information, we can write the point-slope equation:

y - 600 = 15(x - 0)

Simplifying, we get:

y = 15x + 600

This equation tells us the amount James will raise, y, for any number of miles he walks, x. For example, if he completes the 6-mile walk, we can plug in x = 6 to find:

y = 15(6) + 600 = 690

Therefore, if James completes the walk, he will raise $690.

By Simplifying the expression, [tex](π(0.175)^2 - π(0.125)^2)/π(0.175)^2 * 100.[/tex] we find the percentage reduction in the area of the sample due to the test.

To find the percentage reduction in area of the sample, we need to calculate the difference in cross-sectional areas before and after the tensile test.

The cross-sectional area of a rod can be calculated using the formula: [tex]A = πr^2[/tex], where r is the radius of the rod.

Given that the initial diameter of the rod is 0.350 inches, the initial radius (r1) is 0.350/2 = 0.175 inches. Therefore, the initial cross-sectional area (A1) is[tex]π(0.175)^2.[/tex]

Similarly, the final diameter of the rod is 0.250 inches, and the final radius (r2) is 0.250/2 = 0.125 inches. The final cross-sectional area (A2) is [tex]π(0.125)^2[/tex].

Now, we can calculate the percentage reduction in area using the formula: (A1 - A2)/A1 * 100.

Substituting the values, we have: [tex](π(0.175)^2 - π(0.125)^2)/π(0.175)^2 * 100.[/tex]

Therefore, by Simplifying the expression, we find the percentage reduction in the area of the sample due to the test.

The total number of dolls they had in the beginning was 35, and after Jacky gave Peter 15 dolls, they each had 25 dolls. So, they had a total of 50 dolls in all.

Let the initial number of dolls Jacky had be 5x, and the initial number of dolls Peter had be 2x. So, the total number of dolls they had in the beginning was 5x + 2x = 7x.

After Jacky gave Peter 15 dolls, Peter had (2x + 15) dolls, and Jacky had (5x - 15) dolls. As they had an equal number of dolls after this, we get the equation:

5x - 15 = 2x + 15

Simplifying this, we get:

3x = 30

x = 10

So, the initial number of dolls Jacky had was 5x = 50, and the initial number of dolls Peter had was 2x = 20. Therefore, the total number of dolls they had in the beginning was 50 + 20 = 70.

Based on the sample data and the hypothesis test, Bill McWaffle should not take a public position on the issue of gambling legalization.

Using the normal approximation, we can calculate the test statistic, which follows a standard normal distribution under the null hypothesis. The test statistic is given by:

Z = (p - p₀) / √(p₀(1 - p₀) / n),

where p₀ represents the proportion specified under the null hypothesis, which is 0.65 in this case.

Substituting the values into the formula, we have:

Z = (0.34 - 0.65) / √(0.65(1 - 0.65) / 200) ≈ -9.91.

Looking up the z-value in a standard normal distribution table or using statistical software, we find that the critical value for a one-sided 99 percent confidence level is approximately 2.33.

Since the test statistic (Z = -9.91) is much smaller (in absolute value) than the critical value (2.33), we have strong evidence to reject the null hypothesis. This means that the proportion of constituents in favor of legalization is significantly less than 65 percent.

The probability of x not lies in BD = 0.264

Given that,

Number of points between AE = 19

Number of points between BD = 14

Then number of total outcomes = 19

Thus, favorable outcomes are those that satisfy an event's condition, while probability refers to how probable something is to occur.

Then number of favorable outcomes = 14

Since we know that,

Probability is the ratio of number of favorable outcomes and total number of outcomes. it deals with finding out the likelihood of the occurrence of an event.

Therefore,

Probability = (favorable outcomes)/(total outcomes)

Then,

P(X in BD)  = 14/19

x = 14

Therefore, Bart's current age is x = 14, and Paul's current age is 3x = 42.

To check our answer, we can verify that in 14 years, Paul's age will be twice Bart's age:

Let's assume the height of the rectangle is h cm. According to the problem, the base is 1 cm more than the height, so the base would be (h + 1) cm. The formula for the area of a rectangle is given by A = length × width.

Given that the area is 100 cm², we can write the equation as follows:

100 = h × (h + 1)

To solve this equation using a trial and improvement method, we can start by assuming a value for h and check if it satisfies the equation. Let's try h = 9:

100 = 9 × (9 + 1)

100 = 9 × 10

100 = 90

Since 90 is not equal to 100, we can try a different value. Let's try h = 10:

100 = 10 × (10 + 1)

100 = 10 × 11

100 = 110

Again, 110 is not equal to 100. We can continue this process until we find a value of h that satisfies the equation. Let's try h = 9.5:

100 = 9.5 × (9.5 + 1)

100 = 9.5 × 10.5

100 = 99.75

Now, 99.75 is close to 100 but not exactly. Let's try h = 9.6:

100 = 9.6 × (9.6 + 1)

100 = 9.6 × 10.6

100 = 101.76

101.76 is greater than 100, so we can conclude that the value of h is closer to 9.5 than 9.6. Therefore, the value of h, correct to 1 decimal place, is approximately 9.5 cm.
