If represents a mean, it would be a sample mean.

When we develop statistics studies, we define a sample, which represents a sub-group of the population. All statistics analysis are applied to the sample, because it's easier to deal with. So, to develop a correct analysis, the sample has to represent the population, it has to be large enough to generalise its results.

That's why the mean would represent the sample 187.

step-by-step explanation:

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24
