Question

The very last question. i need this now its an important grade.

Answer 1

158

Explanation:

So the sample size said 15 out of 50. Using the sample size to relate to the total number of students, we get this ratio

`(15)/(50) = (x)/(526)`

Let's cross multiply

`50x = (15)(526)`

`50x = 7890`

Last, divide by 50 to get X alone

`x = 157.8`

Which rounds up to 158
