Answer:
Choice D
Step-by-step explanation:
Choice D, 3072ft^2 is the correct answer.
Here's how! The length AND width are both 24, so we know that 24 * 24 is our start. Then the height of the pyramid is 16, which now makes our equation 24 * 24 * 16. When finding the volume of a pyramid, you must divide by 3, so now the answer is (24 * 24 * 16) / 3. Making the answer 3072ft^2.
Hope this helped!
Answer:
3072
Step-by-step explanation:
volume =(1/3) hight ×width×length
v=(1/3) × 16 × 24 × 24

6) The cost of a computer system increases with increased processor speeds. The cost C
of a system as a function of processor speed is estimated as C = 1234 - 35 + 1900,
where S is the processor speed in MHz. Find the processor speed for which cost is at a
minimum. [4 marks]
Answer:
The speed is: 0.0142MHz
Step-by-step explanation:
Given
[tex]C(s) = 1234s^2 - 35s + 1900[/tex]
Required
The processor speed when the cost is at minimum
First, differentiate C(s) with respect to s
[tex]C(s) = 1234s^2 - 35s + 1900[/tex]
[tex]C'(s) = 2468s - 35[/tex]
The cost is at minimum when [tex]C'(s) = 0[/tex]
So, we have:
[tex]C' = 2468s - 35 = 0[/tex]
[tex]2468s - 35 = 0[/tex]
Solve for s
[tex]2468s = 35[/tex]
[tex]s=\frac{35}{2468}[/tex]
[tex]s\approx0.0142[/tex]

Angle W is shown in the diagram.
w
400
What is the measure of Angle w in degrees?
Answer:
The measure of Angle w in degrees is 50°
Step-by-step explanation:
We know that in a straight line, 180°
So,
90° + 40° + w = 180°
130° + w = 180°
w = 180° - 130°
w = 50°
Thus, The measure of Angle w in degrees is 50°

6.18 heart transplant success. the stanford university heart transplant study was conducted to determine whether an experimental heart transplant program increased lifespan. each patient entering the program was officially designated a heart transplant candidate, meaning that he was gravely ill and might benefit from a new heart. patients were randomly assigned into treatment and control groups. patients in the treatment group received a transplant, and those in the control group did not. the table below displays how many patients survived and died in each group.22 control treatment alive 4 24 dead 30 45 suppose we are interested in estimating the difference in survival rate between the control and treatment groups using a confidence interval. explain why we cannot construct such an interval using the normal approximation. what might go wrong if we constructed the confidence interval despite this problem?
We cannot construct a confidence interval using the normal approximation in this case because the sample sizes of the control and treatment groups are relatively small (less than 30), and the data does not meet the assumptions required for the normal approximation.
The normal approximation assumes that the data follows a normal distribution, and for sample sizes less than 30, the distribution of the sample mean may not be well approximated by a normal distribution. In addition, the normal approximation assumes that the observations are independent, which may not hold true in this study due to the nature of the treatment and control groups.
If we constructed a confidence interval despite these problems, the interval may not accurately reflect the true difference in survival rates between the control and treatment groups. The interval could be biased or too wide/narrow, leading to incorrect conclusions about the effectiveness of the heart transplant program. Therefore, it is important to use appropriate statistical methods that account for the specific characteristics of the data and study design in order to obtain reliable estimates and valid inferences.

Roger brought some sponges. The number of packages he bought was 14 less than the number of sponges per package. Roger bought 51 sponges in all. How many packages of sponges did roger buy?
Answer:
the number of sponges per package bought be 32.5
Step-by-step explanation:
Let us assume the number of sponges per package be x
So the number of packages he bought be x - 14
And, the overall he bought 51 sponges
So
the number of packages of sponges did roger buy is
x + x - 14 = 51
2x = 51 + 14
2x = 65
x = 32.5
So the number of sponges per package bought be 32.5

Right triangle EFG it is known that the side opposite of acute angle F has a length of 18 inches and the leg adjacent to F has a length of 14 inches. Which of the following is closest to angle F
1. 38° 2. 65° 3. 52° 4. 72°
Answer:
3
Step-by-step explanation:
The closest angle to F in the triangle is 52 degrees.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
Given that Right triangle EFG it is known that the side opposite of acute angle F has a length of 18 inches and the leg adjacent to F has a length of 14 inches.
We can use the tangent function to find the measure of angle F:
tan(F) = opposite/adjacent = 18/14
we can find the inverse tangent of this value:
F = tan⁻¹(18/14)
= tan⁻¹(1.28)
F= 52.15°
Hence, the closest angle to F in the triangle is 52 degrees.

Bryan is a waiter. He waits on a table of 4 whose bill comes to $110.31. If Bryan receives a 15% tip, approximately how much will he receive?
If Bryan receives a 15% tip, then he will receive an amount of approximately $16.55 as a tip.
In order to calculate the tip-amount, we need to multiply the total-bill by the tip percentage. In this case, the "bill-amount" is $110.31, and the tip percentage is 15%.
To find the tip amount, we can use the formula:
Tip amount = (Total bill) × (Tip percentage),
Simplifying further,
We get,
Tip amount = $110.31 × 0.15,
= $16.5465 (rounded to the nearest cent)
Therefore, Bryan will receive approximately $16.55 as a tip.

A telephone company representative estimates that 40% of its customers have call-waiting service. To test this hypothesis, she selected a sample of 100 customers and found that 37% had call waiting. At α-0.01 , is there enough evidence to reject the claim?
Using the null-hypothesis to calculate the test-statistic at a significance level of 0.01, there is not enough evidence to reject the claim that 40% of the telephone company's customers have call-waiting service based on the sample data.
Is there enough evidence to reject the claim?To test the hypothesis that 40% of the telephone company's customers have call-waiting service, we can conduct a hypothesis test.
Let's set up the null and alternative hypotheses:
Null hypothesis (H₀): The proportion of customers with call-waiting service is 40%.
Alternative hypothesis (H₁): The proportion of customers with call-waiting service is not 40%.
We can use the t-test for proportions to perform the hypothesis test. The test statistic is given by:
z = (p - p₀) / √((p₀ * (1 - p₀)) / n)
where p is the sample proportion, p₀ is the hypothesized proportion, and n is the sample size.
In this case, p₀ = 0.40, p = 0.37, and n = 100.
Calculating the test statistic:
z = (0.37 - 0.40) / √((0.40 * (1 - 0.40)) / 100)
z = -0.03 / √(0.24 / 100)
z = -0.03 / 0.049
z = -0.612
To determine if there is enough evidence to reject the null hypothesis, we compare the calculated z-value with the critical z-value at a significance level of α = 0.01.
The critical z-value for a two-tailed test at α = 0.01 is approximately ±2.576.
Since -0.612 falls within the range of -2.576 to 2.576, we fail to reject the null hypothesis.

If angle A=320∘, what is the radian measure of A? Give your answer as an exact fraction in terms of π.
The radian measure of angle A is (16/9)π.
To convert degrees to radians, we use the conversion factor:
[tex]1\ degree = \pi /180\ radians[/tex]
Given that angle A is 320 degrees, we can calculate its radian measure as follows:
Angle A in radians = (320 degrees) * (π/180 radians/degree)
= (320π)/180 radians
= (16/9)π radians
Therefore, the radian measure of angle A is (16/9)π.
