Answer:
D. Obtain a cluster sample by randomly selecting 20 counties and visiting every restaurant within those counties.
Step-by-step explanation:
Since this executive wants to minimize cost and expenses he should use a cluster sample of 20 counties and using the selected counties as a representative of the whole. Cluster sampling is a good and useful way of doing market research. It is more economical than other sampling methods and as the executive cannot get information on the whole population, he would be able to get information from the clusters.

For each of the following sampling situations, identify the population as exactly as possible. That is, say what kind of individuals the population consists of and say exactly which individuals fall in the population. If the information given is not complete, complete the description of the population in a reasonable way.
a. A college has changed its core curriculum and wants to obtain detailed feedback information from the students during each of the first 12 weeks of the coming semester. Each week, a random sample of 5 students will be selected to be interviewed.
b. The American Community Survey (ACS) will replace the census "long form" starting with the 2010 census. The main part of the ACS contacts 250,000 addresses by mail each month, with follow-up by phone and in person if there is no response. Each household answers questions about their housing, economic, and social status.
c. An opinion poll contacts 1161 adults and asks them, "Which political party do you think has better ideas for leading the country in the twenty-first century?"
Here are the options that complete the questions;
For question 1. (a):
A) The population is all current students.
B) The population is students in the college during the first 12 weeks of the coming semester.
C) The population is the 60 students selected during the first 12 weeks of the coming semester.
D) The population is students in the coming semester.
For question 2. (b):
A) The population is 250,000 households.
B) The population is all U.S. households.
C) The population is all households that are being contacted by the ACS.
D) The population is U.S. households in 2010.
For question 3. (c):
A) The population is 1161 U.S. adults that supply information.
B) The population is all adult residents of the U.S.
C) The population is political parties.
D) None of the above.
Answer:
For question 1. (a) = B) The population is students in the college during the first 12 weeks of the coming semester.
For question 2. (b): = D) The population is U.S. households in 2010.
For question 3. (c): = B) The population is all adult residents of the U.S.
Explanation:
a) We can conclude that the research population would consist of students in the college during the first 12 weeks of the coming semester because students that failed to register for the 12 weeks of the coming semester are would not be counted in the random sample selection process.
b) The American Community Survey (ACS) as the name implies serves the entire American community; thus the population of the census is all U.S. households in 2010.
c) Although 1161 adults are been contacted, they do not represent the entire population, but just a sample out of all adult residents of the U.S.

If f(x) = 3^2 + 1 and g(x) = 1 – x, what is the value of (f – g)(2)?
Answer:
(f - g)(2) = 11
Step-by-step explanation:
f(x) = 3² + 1
g(x) = 1 - x
(f - g)(2) = f(2) - g(2)
f(2) = 9 + 1 = 10
g(2) = 1 - 2 = -1
10 - (-1) = 10 + 1 = 11
(f - g)(2) = 11

The double number line shows how many bananas are needed to make 1 loaf
of banana bread.
Answer:
(1, 2.5) (2, 5) (4, 10)
Step-by-step explanation:
The first blank is 1 because that's how many loaves are made while using the equivalent point on the second number line. Then you just use that same input for the second blank (2). The second blank is just the first one multiplied by 2. For the final blank you want to multiply 4 by the unit rate of bananas: 2.5. The last blank is 10.
PLEASE MARK BRAINLIEST!!!
The number of bananas is represented by the set of coordinates (1, 2.5) (2, 5) (4, 10).
What is a number line?A number line in elementary mathematics is a representation of a graduated straight line that serves as an abstraction for real numbers, represented by the symbol R." It is assumed that every point on a number line corresponds to a real number and that every real number corresponds to a point.
The first blank is 1 because utilizing the equivalent point on the second number line, one loaf is produced. The second blank is then filled in using the same input (2). The second blank is simply the first blank times two. You need to multiply 4 by the banana unit rate of 2.5 for the final blank. The final space is 10.
Therefore, the number of bananas is represented by the set of coordinates (1, 2.5) (2, 5) (4, 10).

A box has length 6 feet, width 4 feet, and height 5 inches. Find the volume of the box in cubic feet and in cubic inches.
The volume of the rectangular box will be 120 cubic inches.
What is the volume?Volume is defined as the space occupied by any object in the three dimensions. All three parameters are required for the volume like length, width, and height of cube or cubes.
Given that the box has a length of 6 feet, a width of 4 feet, and a height of 5 inches.
The volume will be calculated by the formula,
Volume = 6 x 5 x 4
Volume = 120 Square inches
Therefore, the volume of the box has dimensions of a length of 6 feet, a width of 4 feet, and a height of 5 inches.

New glasses cost £80. If the prices fall by 5% in the sale – what is the new price of the glasses?
Answer:
£76
Step-by-step explanation:
5% is the same as 0.05. 100% is the same as 1. To get the price of the new glasses we have to subtract 0.05 from 1 and multiply that by the original price. We get 0.95 and 0.95 times 80 and now you have 76 pound.

r(x) is the same as a(x) - b(x)
a(x) - b(x)

10. Two angles are supplementary. The smaller angle is 201° less than twice the larger angle. What is the measure of the
larger angle?
Answer:
The larger angle is 127 degrees
Step-by-step explanation:
Given
Represent the two angles with a and b
[tex]a = 2b - 201[/tex]
Required
Determine a and b
Since a and b are supplementary, then:
[tex]a + b = 180[/tex]
Substitute 2b - 201 for a
[tex]2b - 201 + b = 180[/tex]
Collect Like Terms
[tex]2b + b = 180 + 201[/tex]
[tex]3b = 381[/tex]
[tex]b = 381/3[/tex]
[tex]b = 127[/tex]
Recall that
[tex]a = 2b - 201[/tex]
[tex]a = 2 * 127 - 201[/tex]
[tex]a = 254- 201[/tex]
[tex]a = 53[/tex]
Hence:
The angles are 53 and 127 degrees, respectively
