The height of the square pyramid is 58.95 units.

To find the height of the square pyramid, we can use the Pythagorean theorem. Let's call the height "h".

The slant height is the hypotenuse of a right triangle with legs equal to half the length of one side of the square base and the height of the pyramid. The length of one side of the square base is given as 22, so the length of half a side is 11. Using the Pythagorean theorem, we get:

[tex]h^{2}[/tex] + [tex]11^{2}[/tex] = [tex]60^{2}[/tex]

Simplifying, we have:

[tex]h^{2}[/tex]  + 121 = 3600

Subtracting 121 from both sides, we get:

[tex]h^{2}[/tex]  = 3479

We need more information about the property and the specific services required to determine the price of Hillary's home.

Answer:

Unfortunately, without additional information, it is impossible to determine the price of Hillary's home. The range of closing costs provided does not provide enough information to calculate the price of the home.

To determine the price of the home, we would need to know either the exact amount of the closing costs or additional information about the home's value, such as its appraised value or sale price.

Therefore, we cannot determine the price of Hillary's home based on the given information.

Step-by-step explanation:

We only know that the estimated closing costs for her home range from $11,600 to $40,600. Closing costs can vary based on a variety of factors, such as the location of the home, the type of mortgage, and the specific fees charged by the lender and other parties involved in the transaction.

To determine the price of Hillary's home, we would need additional information, such as the appraised value of the home, the amount of the down payment, and the specific closing costs that were incurred.

Answer:

Mr. Johnson should be paid $285 for a job requiring 60 hours of work.

Step-by-step explanation:

If Mr. Johnson was paid $190 for 40 hours of work, then we can write:

190/40 = x/60

Where x is the amount he should be paid for 60 hours of work.

To solve for x, we can cross-multiply and simplify:

190 * 60 = 40 * x

11,400 = 40x

x = 11,400/40

x = 285

Therefore, Mr. Johnson should be paid $285 for a job requiring 60 hours of work at the same rate.

The probability that the student chosen at random is male AND got a "C" is 0.0227.

Conditional probability is the probability of an event (A) occurring given that another event (B) has already occurred. It is denoted by P(A | B) and is read as "the probability of A given B".

The formula for conditional probability is:

P(A | B) = P(A and B) / P(B)

Where P(A and B) is the probability of both events A and B occurring, and P(B) is the probability of event B occurring.

Here we have

The total number of students is 88

Out of these 88 students, 36 are male

Number of males that got grade C =  2

P(male AND C) =  number of males who got C / total number of students

= 2/88 = 0.02272727272  

Rounding this to 4 decimal places, we get:

P(male AND C) = 0.0227

Therefore

The probability that the student chosen at random is male AND got a "C" is 0.0227.

The value of test statistic is -2.23.

What is test statistic?

In statistics, a test statistic is a value calculated from a sample of data that is used to assess the evidence against a null hypothesis.

We can use a one-sample t-test to test the hypothesis:

Null hypothesis: The true population mean cost of weddings is $25,549

Alternative hypothesis: The true population mean cost of weddings is less than $25,549

The test statistic can be calculated using the formula:

t = ([tex]\bar{x}[/tex] - μ) / (s / √n)

where [tex]\bar{x}[/tex] is the sample mean, μ is the hypothesized population mean, s is the sample standard deviation, and n is the sample size.

Plugging in the given values, we get:

t = (24,342 - 25,549) / (5054 / √60) = -2.23

According to the information, the maximum infection rate is:  k * 2500 * (5000 - 2500) = 6250k = 40

To address this problem, we can use the law of the infection rate, which states that the infection rate is directly proportional to the product of the number of people infected and the number of people not infected. Therefore, we can write:

where "k" is a constant of proportionality. Since we want to find the number of people infected that produces the maximum infection rate, we can consider the infection rate as a function of the variable "x" representing the number of people infected. Therefore, we can write:

To find the value of "x" that maximizes the infection rate, we can derive this function and set the derivative equal to zero:

This implies that 5000 - 2x = 0, and therefore:

Therefore, the number of infected people that produces the maximum daily rate of infection is 2,500.

However, we must verify that this result is consistent with the information given in the problem. We know that when there are 1,000 people infected, the flu spreads at the rate of 40 new cases per day. Therefore, if we add 1,500 more infected people (for a total of 2,500), the infection rate would be:

Answer:

I'm pretty sure the answer is 14 feet. hope this helps!

Answer:

To find the p-value, we need to first find the corresponding area in the normal distribution table for the test statistic of 1.75.

Since the sample size (n) is greater than 30 and the population standard deviation is unknown, we use the t-distribution to calculate the p-value.

The degrees of freedom (df) for the t-distribution is n - 1 = 20 - 1 = 19.

Using a t-table or calculator, we can find that the area to the right of 1.75 (with df=19) is approximately 0.049.

Since this is a one-tailed test (the alternative hypothesis is that the mean wait time is greater than 2 minutes), the p-value is equal to the area to the right of the test statistic, which is 0.049.

Therefore, the corresponding p-value is 0.049 (rounded to three decimal places).

x² + (y - 3)² = 36; x² + (y + 8)² =36 represent the circles that have a diameter of 12 units and a center that lies on the Y axis.

We know that the abscissa of coordinates of a point on Y axis is 0.

So the equation of a circle center at (0, k) and radius 'r' is given by,

x² + (y - k)² = r²

Here given that the diameter of the circle must be = 12 units

So the radius of the circle = 12/2 = 6 units.

So the equation of the required circle looks like

x² + (y - k)² = 6², where k is an real number.

x² + (y - k)² = 36

So we can see that the equations x² + (y - 3)² = 36; x² + (y + 8)² =36 can be the equation of the required circle.

Check the picture below.

After considering all the given data we conclude that the generated answers to the sub questions are

a) 120 feet

b) 1200 inches

c) 120 inches tall

d) 72

e) 1

f) 1

g) proportional

a. To evaluate the height of the flagpole needed to support a 30 by 42 feet flag, we can apply the ratio of the height of a flagpole to the width of any flag which is 4 to 1.

This projects that the height of the flagpole is be four times the width of the flag. The width of the flag is 30 feet, so the height of the flagpole should be 4 × 30 feet = 120 feet.

b. If the individual have a model of Ft. McHenry that you need to add a flagpole to that will be proportional to the real pole at the fort and the ratio of the model is 1 inch to 10 feet, then you can apply this ratio to determine how tall the individuals model flagpole should be.

The real pole at Fort McHenry is 120 feet tall (as determined in part a), so you can multiply this by 10

10 × 120 = 1200

to get 1200 inches. This means that your model flagpole should be 1200 inches tall.

c. It is given that a model flagpole that is 8 inches tall; this is not the correct size. To evaluate how tall it needs to be, we can use the same ratio as in part b.

The real pole at Fort McHenry is 120 feet tall (as determined in part a), so you can multiply this by 10 to get 1200 inches.

This means that your model flagpole should be 1200/10 = 120 inches tall.

d. To evaluate if the model flag and original flag are similar figures, we can compare their corresponding sides.

The original flag has dimensions of 30 by 42 feet, which is equivalent to 360 by 504 inches. The model flag has dimensions of 5 by 6.3 inches. To determine if they are similar figures, we can compare their corresponding sides using ratios.

The ratio of the length of corresponding sides must be equal for two figures to be similar. The length of corresponding sides for these two flags are:

- Original Flag: Length = 360 inches; Width = 504 inches

- Model Flag: Length = 5 inches; Width = 6.3 inches

To compare these lengths, we can divide each length by its corresponding length on the other figure:

- Length Ratio: (360 / 5) = 72

- Width Ratio: (504 / 6.3) = 80

Since these ratios are not equal, these two flags are not similar figures.

To find out what dimensions would make them similar figures, we can use these ratios as scale factors:

Length Scale Factor: (360 / x) = 72

- Width Scale Factor: (504 / y) = 80

Evaluating for x and y gives us:

- x = (360 / 72) = 5

- y = (504 / 80) = 6.3

This means that if we scaled down the original flag by a factor of 72, its dimensions would be equivalent to those of the model flag.

e. To evaluate the ratio of the perimeter of the model flag in comparison to the original flag using the scale factor from part d:

Perimeter Scale Factor: (72 + 80) / 2 = 76

Model Flag Perimeter: (2 * (5 + 6.3)) = 23.6

- Original Flag Perimeter: (2 * (360 + 504)) = 1688

The ratio of these perimeters is:

Perimeter Ratio: (23.6 / (1688 /76)) ≈ 1

This means that the perimeter of the model flag is approximately equal to that of the original flag.

f. To evaluate the ratio of area between these two flags using scale factor from part d:

- Area Scale Factor: (72 × 80) = 5760

- Model Flag Area: (5 × 6.3) ≈ 31.5

- Original Flag Area: (360 × 504) ≈ 181440

The ratio of these areas is:

Area Ratio: (31.5 / (181440 /5760)) ≈ 1

This means that area of model flag is approximately equal to that of original flag.
