An employer with 500 employees gives out gives out 120 surveys but receives only 90 surveys completed by the employees. What are
leva [86]

Answer:

Population 120 given the survey, sample 90 who answered the survey.

Step-by-step explanation:

The entire amount of employees who even received the surveys at all was 120. Because the total number was 120, 120 is the population.

Only 90 out of 120 surveys were received, so 90 is the sample because it is part of 120.

Hope this helps :)

What is the length of the side of a right triangle that has a hypotenuse that is 15 mm and a side that is 9 mm?
ycow [4]
A. 12 mm

The Pythagorean Theorem states that a^2 + b^2 = c^2 with a and b being lengths of legs and c being the length of a hypotenuse. So we can use our givens to solve for the remaining leg. 

9^2 + b^2 = 15^2
81 + b^2 = 225
b^2 = 144
b = 12
