Answer:
n ≤ 6
Step-by-step explanation:
Representing the number of goldfish that can live in a small tank as n, we can express this constraint as
n ≤ 6
Standard deviation is a number used to tell how measurements for a group are spread out from the average (mean), or expected value. A low standard deviation means that most of the numbers are close to the average. A high standard deviation means that the numbers are more spread out.
Answer:
A. 
Step-by-step explanation:
I could not make clarifications of what you are asking, but this is similar to

To find the ratio of their perimeters, you need to know that the ratio of a perimeter is the square root of the ratio of the areas. (Area is 2 dimensional, so what you do to the perimeter will have twice or be squared for the area).
So, you would simplify the ratio of 18/32 to 9/16.
Then take the square root of 9 and 16 separately to find the ratio of the perimeters.
Square root of 9 is 3.
Square root of 16 is 4
So, the ratio of the perimeters is 3 in/4 in.
Letters that can stand for numbers. When we substitute a specific value for each variable and then perform the operation, it's called evaluating the expression
For Example: Let's evaluate the expression
3y + 2y when 5 = y.
