The administration of a large university is interested in learning about the types of wellness programs that would interest its employees. To do this, they plan to survey a random sample of employees. Under consideration are several plans for selecting the sample. Which of the following sampling strategies is the stratified sampling?
a. There are five categories of employees (administration faculty, professional staff, clerical and maintenance). Randomly select ten individuals from each category.
b. Fach employee has an ID number. Randomly select 50 numbers.
c. Randomly select a school within the university (eg, Business School) and survey all of the individuals (administration, faculty, professional staff, clerical and maintenance) who work in that school.
d. The HR Department has an alphabetized list of newly hired employees (hired within the last five years). After starting the process by randomly selecting an employee from the list, then every 5th name is chosen to be included in the sample.
Step-by-step explanation:
Stratified sampling is a sampling strategy from a population that involves sampling by dividing or partitioning the population into smaller subgroups.
So the correct answer is "There are five categories of employees (administration faculty, professional staff, clerical and maintenance). Randomly select ten individuals from each category." because it involves dividing the population into subgroups.

Answer: x = 0
Explanation
The idea is to replace h(x) with 3. Then we isolate x. Follow PEMDAS in reverse to get x by itself.
Here are the steps:
h(x) = -5x+3
3 = -5x+3
-5x+3 = 3
-5x = 3-3
-5x = 0
x = 0/(-5)
x = 0
As a check,
h(x) = -5x+3
h(0) = -5*0 + 3
h(0) = 0 + 3
h(0) = 3
Therefore, the input x = 0 in the domain leads to the output h(x) = 3 in the range. We have confirmed the answer x = 0
Another way to confirm the answer is to use a graphing tool like GeoGebra or Desmos.

Answer:
Mean = 5 feet 2 inches.
Step-by-step explanation:
1 feet = 12 inches
Height of Dad = 6 feet 2 inches = {(6 × 12)+2} = 74 inches
Mom is 3 inches shorter than dad = 74 - 3 = 71 inches (5 ft 11 in)
Since mom is 2 inches taller than Ivan,
Height of Ivan = 71 - 2 = 69 inches (5 ft 9 in)
Marica is 5 inches shorter than Ivan,
Height of Marica = 69 - 5 = 64 inches (5 ft 4 in)
Marica is twice as tall as Sally-Jo.
Height of Sally-Jo = 64 ÷ 2 = 32 inches (2 ft 8 in)
Hence the mean height of the Schuller family
=
= 62 inches
converting 62 inches to feet = = 5 feet 2 inches
Mean height of the Schuller family is 5 feet 2 inches.

There is no effect of denominator to find equivalent fraction of any rational number, whether the denominator is greater than 6 or less than 6, but denominator should not be equal to Zero.
We can find equivalent fraction of any rational number , the denominator of that rational number should not be equal to Zero.

Answer:
13,250,000 feet or 13.25 million feet
Step-by-step explanation:
Each person in the line has a shoulder width of 1.325 feet.
For each person, there is a width of 1.325 ft. There are 10 million people.
Since:
10 million = 10,000,000
The total length must be:
Answer: 13,250,000 feet or 13.25 million feet
Final answer:
By simply multiplying the average shoulder width of the people (1.325 feet) by the total number of people in the line (10 million), the total length of the line would be 13,250,000 feet.
Explanation:
This problem can be solved by using simple multiplication. Given that the average shoulder width of the people in the line is 1.325 feet, we simply need to multiply this by the total number of people in the line, which is 10 million in this case.
So, 1.325 feet * 10,000,000 = 13,250,000 feet.
Therefore, if there were 10 million people in line, and the average shoulder width of each person is 1.325 feet, the total length of the line would be 13,250,000 feet.
