Answer:

Step-by-step explanation:

Assuming that the given dimensions of 13, 13, 13 refer to the base of the rectangular pyramid, we can calculate the surface area of the pyramid as follows:

First, we need to calculate the area of the rectangular base, which is simply length x width:

Area of rectangular base = 13 x 13 = 169 square units

Next, we need to calculate the area of each triangular face of the pyramid. Since the rectangular base has two sets of parallel sides, there are two types of triangular faces: the isosceles triangles on the sides and the right triangles on the front and back.

To calculate the area of the isosceles triangles, we need to first find the length of the slant height, which can be found using the Pythagorean theorem:

a² + b² = c²

where a and b are the base and height of the triangle (both equal to 13 in this case), and c is the slant height.

13² + 13² = c²

338 = c²

c ≈ 18.38

Now that we have the slant height, we can calculate the area of each isosceles triangle using the formula:

Area of isosceles triangle = (1/2) x base x height

Area of isosceles triangle = (1/2) x 13 x 18.38

Area of isosceles triangle ≈ 119.14 square units

To calculate the area of each right triangle, we need to use the same slant height of 18.38, along with the height of the pyramid, which is also 13. Then we can use the formula:

Area of right triangle = (1/2) x base x height

Area of right triangle = (1/2) x 13 x 18.38

Area of right triangle ≈ 119.14 square units

Since there are two of each type of triangular face, the total surface area of the pyramid is:

Surface area = area of rectangular base + 2 x area of isosceles triangle + 2 x area of right triangle

Surface area = 169 + 2 x 119.14 + 2 x 119.14

Surface area = 546.28 square units

Therefore, the surface area of the rectangular pyramid with base dimensions of 13 x 13 and height of 13 is approximately 546.28 square units.

Considering that the surface area and the volume of the cylinders are equal, the surface areas are given as follows:

108π ft².

250π ft².

Here, we have,

the surface area and the volume of a cylinder:

For a cylinder of radius r and height h, the surface area is given by:

S = 2πr(h + r).

The volume is given by:

V = πr²h.

For item 14, the parameters are given as follows:

r = 6 ft, h = x ft.

Hence we solve for x equaling the surface area and the volume as follows:

V = S

36πx = 12π(x + 6)

3x = x + 6

2x = 6.

x = 3.

Hence the surface area is:

S = 12π(3 + 6) = 108π ft².

For item 15, the parameters are given as follows:

r = 10 ft, h = x ft.

Hence we solve for x equaling the surface area and the volume as follows:

V = S

100πx = 20π(x + 10)

5x = x + 10

4x = 10.

x = 2.5.

Hence the surface area is:

S = 20π(2.5 + 10) = 250π ft².

The missing test scores were both 8.3. The standard deviation for the test scores was 21.66. The difference between the harmonic mean and the geometric mean of the 12 students was 3.26.

The sum of the scores of the 10 students is 63. The average score of the 10 students is

(63 + x + x) / 12 = 8.3

Solving for x, we get

x = 8.3 * 12 - 63 - 13.8 - 10.4

x = 100.6 - 63 - 13.8 - 10.4

x = 13.4

Therefore, each missing script has a score of 13.4.

To find the standard deviation, we first need to find the variance

Find the mean

(2.7 + 6.3 + 4.1 + 6.4 + 3.5 + 4.7 + 13.8 + 79 + 12.1 + 10.4 + 13.4 + 13.4) / 12 = 11.0

Subtract the mean from each score and square the result

(2.7 - 11)², (6.3 - 11)², (4.1 - 11)², (6.4 - 11)², (3.5 - 11)², (4.7 - 11)², (13.8 - 11)², (79 - 11)², (12.1 - 11)², (10.4 - 11)², (13.4 - 11)², (13.4 - 11)²

Add up the squared differences

5697.36

Divide by the number of scores minus one, to get the variance

5697.36 / 11 = 517.03

Take the square root of the variance to get the standard deviation

√(517.03) = 22.76

Therefore, the standard deviation for the test scores is 22.76.

The harmonic mean is calculated by dividing the number of scores by the sum of the reciprocals of the scores, and then taking the reciprocal of the result

12 / (1/2.7 + 1/6.3 + 1/4.1 + 1/6.4 + 1/3.5 + 1/4.7 + 1/13.8 + 1/79 + 1/12.1 + 1/10.4 + 1/13.4 + 1/13.4) = 5.04

The geometric mean is calculated by taking the product of all the scores, and then taking the nth root of the product, where n is the number of scores

(2.7 * 6.3 * 4.1 * 6.4 * 3.5 * 4.7 * 13.8 * 79 * 12.1 * 10.4 * 13.4 * 13.4)^(1/12) = 8.30

Therefore, the difference between the harmonic mean and the geometric mean is

We can conclude here that we have sufficient evidence that the mean score is not equal to 571.

The test statistic here is computed as:

Now the p-value for n-1 = 25 degrees of freedom here is computed from the t-distribution tables as:

p = 2P( t25 > 1.9953 ) = 2*0.0285 = 0.0570

0.05 < P-value < 0.1

As the p-value here is 0.0570 < 0.1 which is the level of significance, therefore the test is significant and we can reject the null hypothesis here.

The total surface area of the clubhouse including the floor is approximately 95.98 square feet.

We have,

The surface area of a square pyramid can be found by adding the area of the base to the sum of the areas of the four triangular faces.

Since the base is a square, its area is 6^2 = 36 square feet.

Each triangular face is an equilateral triangle with a side length of 6 feet, so its area can be found using the formula.

A = (√(3)/4) x s²,

where s is the length of a side.

The area of each triangular face.

A = (√(3)/4) x 6² = 9 √(3) square feet.

The total surface area is then:

A = 4 x 9 √(3) + 36

A = 36 √(3) + 36  ≈ 95.98 square feet

(rounded to the nearest hundredth)

An exponential function models situations in which a quantity grows or decays by a constant percentage or factor over equal intervals of time.

Let's analyze each situation:

A. The number of fish in a tank increases by five per month.

This situation represents a constant increase (addition) of fish every month. It can be modeled by a linear function, not an exponential function.

B. The number of people in a city increases by 100 every year.

This situation also represents a constant increase (addition) in the number of people per year. It can be modeled by a linear function, not an exponential function.

C. The value of a car at the end of a year is 8 percent less than the value at the beginning of the year.

This situation represents a constant percentage decrease (multiplication) in the value of the car each year. It can be modeled by an exponential function (e.g., V(t) = V_0 * (1 - 0.08)^t, where V(t) is the value of the car after t years and V_0 is the initial value of the car).

D. The value of a phone drops $100 per year.

The 46th term of the sequence is 324.

We have,

To find the 46th term of the sequence, we need to determine the pattern or rule that generates the terms.

Since the difference between consecutive terms is a constant value of 7, we know that this is an arithmetic sequence with a common difference

of 7.

To find the 46th term, we can use the formula for the nth term of an arithmetic sequence:

a(n) = a(1) + (n - 1) d

where a(1) is the first term, d is the common difference, and n is the term number we want to find.

Using the given information, we have:

a(1) = 9

d = 7

n = 46

Plugging these values into the formula, we get:

a (46) = 9 + (46 - 1)7

a (46) = 9 + 45 (7)

a(46) = 9 + 315

The results of the two-sample t-test, there does not appear to be enough evidence to support the claim that the mean FICO score of borrowers with high-interest mortgages is different than the mean FICO score of borrowers with low-interest mortgages.

To test the claim that the mean FICO score of borrowers with high-interest mortgages is different than the mean FICO score of borrowers with low-interest mortgages, we can perform a two-sample t-test.

Using the given data, we can calculate the test statistic as follows:

t = (492 - 508) / sqrt((49^2 / 19) + (38^2 / 26)) = -1.57

The degrees of freedom for this test are 19 + 26 - 2 = 43. Using a t-table or calculator and a significance level of 0.2, we can find the critical value to be approximately ±1.301.

Since the absolute value of the test statistic (1.57) is less than the critical value (1.301), we fail to reject the null hypothesis. This means that we do not have enough evidence to support the claim that the mean FICO score of high-interest mortgage borrowers is different than the mean FICO score of low-interest mortgage borrowers at the 0.2 significance level.
