The composite figure can be decomposed into a triangle, a rectangle, and a semicircle to determine its area.
To decompose the composite figure and determine its area, we can break it down into simpler geometric shapes based on its components. In this case, the composite figure consists of a semicircle, a small rectangle, and a triangle.
We can decompose the figure as a triangle, a rectangle, and a semicircle. Here's how:
Triangle: The upper part of the figure is a triangle. Calculate its area using the formula A = (base * height) / 2, where the base and height are the appropriate measurements.
Rectangle: The small rectangle connects the semicircle to the triangle. Find its area by multiplying the length and width.
Semicircle: The bottom part of the figure is a semicircle. Calculate its area using the formula A = (π * r^2) / 2, where r is the radius of the semicircle.
Once you have determined the areas of each individual shape, add them together to find the total area of the composite figure.

1. (15 points =5 ′×3) Draw two indifference curves (IC) for each of the following pairs of goods and indicate which IC provides a higher utility. Put the quantity of the 1st good on the horizontal axis and the quantity of the 2 nd good on the vertical axis. 1.1 Rhonda likes carrots and dislikes broccoli. 1.2 Emily likes hip-hop iTunes downloads and does not care about heavy metal downloads. 1.3 Steven dislikes both potatoes and fish. Each fish he eats decreases his utility by a smaller amount that the previous fish.
1.1 For Rhonda, who likes carrots and dislikes broccoli, the indifference curves would show a higher level of utility as they move away from broccoli and towards more carrots. The indifference curve representing a higher utility would be the one farther away from the origin and closer to the carrots axis.
This indicates that Rhonda prefers more carrots and less broccoli, and each indifference curve represents a different level of utility. 1.2 For Emily, who likes hip-hop iTunes downloads and doesn't care about heavy metal downloads, the indifference curves would be upward sloping. As the quantity of hip-hop iTunes downloads increases, Emily's utility would increase. Since she doesn't care about heavy metal downloads, the specific shape of the indifference curves would depend on the individual preferences within the hip-hop downloads. The indifference curve representing a higher utility would be the one farther away from the origin and representing a larger quantity of hip-hop iTunes downloads.
1.3 For Steven, who dislikes both potatoes and fish, the indifference curves would be downward sloping. As the quantity of potatoes and fish increases, Steven's utility would decrease. However, the statement mentions that the utility decrease for each additional fish is smaller than the previous one. This suggests that the indifference curves would have a diminishing slope as they move away from the origin. The indifference curve representing a higher utility would be the one closer to the origin, indicating a lower quantity of potatoes and fish.

Many of a bank's customers use its automatic teller machine to transact business after normal banking hours. During the early evening hours in the summer months, customers arrive at a certain location at the rate of one every other minute. This can be modeled using a Poisson distribution. Each customer spends an average of 90 seconds completing his or her transactions. Transaction time is exponentially distributed. Answer the following questions: Compute the probability that a customer will not have to wait upon arriving at the automatic teller machine (2 decimal points)
The probability that a customer will not have to wait upon arriving at the automatic teller machine is 0.78 (rounded to 2 decimal points).
To compute the probability that a customer will not have to wait upon arriving at the automatic teller machine, we need to determine the arrival rate and the service rate.
Customers arrive at a rate of one every other minute. This means the arrival rate (λ) is 1 customer per 2 minutes, or λ = 1/2 customers per minute.
Each customer spends an average of 90 seconds completing their transaction. This means the service rate (μ) is 1 customer per 90 seconds, or μ = 1/90 customers per second.
To calculate the probability that a customer will not have to wait, we can use the M/M/1 queueing model, where M represents the exponential distribution for both arrivals and service.
The formula for the probability that the system is in the empty state (no customers in the system) is given by:
P0 = 1 - (λ/μ)
Substituting the values:
P0 = 1 - (1/2) / (1/90)
P0 = 1 - (45/2)
P0 = 1 - 22.5
P0 = 0.775
Therefore, the probability that a customer will not have to wait upon arriving at the automatic teller machine is 0.78 (rounded to 2 decimal points).

What is the area of the cross section of a sphere with a volume of about 5575. 3 m³
The area of the cross-section of the sphere with a volume of approximately 5575.3 m³ is approximately 330.29 m².
To find the area of the cross-section of a sphere, we need the radius of the sphere. However, given only the volume of the sphere (approximately 5575.3 m³), we cannot directly determine the radius.
The volume of a sphere is calculated using the formula:
V = (4/3) * π * r³,
where V is the volume and r is the radius of the sphere.
To find the radius, we can rearrange the formula:
r = ((3 * V) / (4 * π))^(1/3).
Substituting the given volume into the formula, we have:
r = ((3 * 5575.3) / (4 * π))^(1/3).
Using the value of π as approximately 3.14159, we can calculate the radius:
r ≈ ((3 * 5575.3) / (4 * 3.14159))^(1/3) ≈ 10.25 m.
Now that we have the radius (approximately 10.25 m), we can calculate the area of the cross-section of the sphere.
The formula for the area of a cross-section of a sphere is:
A = π * r².
Substituting the radius we found, we have:
A = π * (10.25)² ≈ 330.29 m².
The area of the cross-section of the sphere with a volume of approximately 5575.3 m³ is approximately 330.29 m².

Indicate whether the statement below is true or false, explain why. Convenience samples are generally not representative of the population
a.False; convenience samples are only representative of small populations.
b. False; convenience samples are usually representative of the population since those readily available are typically the majority. c.True d. False; convenience samples are generally very representative of the populations since they tend to be unbiased.
The statement "Convenience samples are generally not representative of the population" is true.
Convenience samples are a type of non-probability sampling in which the researcher selects participants based on their convenience. This means that the researcher selects participants who are easy to reach or who are available at the time of the study. Convenience samples are often used in research because they are quick and easy to collect.
However, convenience samples are not representative of the population because they do not include all members of the population.
For example, if a researcher is interested in studying the effects of a new medication on people with high blood pressure, they might select participants from a convenience sample of people who are easy to reach, such as people who are already taking medication for high blood pressure. However, this convenience sample would not be representative of the population of people with high blood pressure because it would not include people who are not taking medication for high blood pressure.
Here are the reasons why convenience samples are generally not representative of the population:
Bias: Convenience samples are often biased because the researcher selects participants who are easy to reach or who are available at the time of the study. This can lead to a sample that is not representative of the population because it may include more people from certain groups, such as people who are more educated or people who are more likely to respond to surveys.
Small sample size: Convenience samples are often small in size, which can make it difficult to generalize the results of the study to the population.
Heterogeneity: Convenience samples are often heterogeneous, which means that they include people from different backgrounds and with different experiences. This can make it difficult to identify patterns or trends in the data.
If you are conducting a research study, it is important to use a sampling method that will give you a representative sample of the population. Probability sampling methods, such as simple random sampling and stratified random sampling, are more likely to give you a representative sample than convenience sampling.

Frank is going to rent a truck for one day. There are two companies he can choose from, and they have the following prices. Company A has no initial fee but charges 80 cents for every mile driven. Company B charges an initial fee of $70 and an additional 60 cents for every mile driven. For what mileages will Company A charge more than Company B? Use m for the number of miles driven, and solve your inequality for m. O
Company A will charge more than Company B for mileages greater than 70/(0.60 - 0.80) = 350 miles.
To determine the mileages for which Company A charges more than Company B, we need to compare the cost functions of the two companies. Let C_A(m) represent the cost for Company A and C_B(m) represent the cost for Company B.
For Company A, the cost function is C_A(m) = 0.80m, as there is no initial fee and they charge 80 cents per mile driven.
For Company B, the cost function is C_B(m) = 70 + 0.60m, as there is an initial fee of $70 and an additional 60 cents per mile driven.
To find the mileage at which Company A charges more than Company B, we set the two cost functions equal to each other and solve for m:
0.80m = 70 + 0.60m
0.80m - 0.60m = 70
0.20m = 70
m = 70 / 0.20
m = 350
Therefore, for mileages greater than 350 miles, Company A will charge more than Company B.

Given: The radius of a sphere is increasing at a constant rate of 2 inches per minute. At the instant when the radius of the sphere is 9 inches,
We need to find the rate of change of volume.
Using the formula of the volume of the sphere:
V = (4/3)πr³Where V is the volume and r is the radius.
Now differentiate it with respect to time t on both sides to find the rate of change of volume.
dV/dt = d/dt[(4/3)πr³]
dV/dt = 4πr²(dr/dt)Put the given values in the above formula and solve for dV/dt.
r = 9 inches, dr/dt = 2 inches/minute
So, dV/dt = 4πr²(dr/dt)dV/dt
= 4π(9²)(2)
