Question

A sample of students is taken from the school's A honor roll. The school estimates that there are actually 360 students on the A honor roll. Using this sample, how many students on the A honor roll are 7th graders

Answer 1

There are 99 students that are 7th graders on the A honor roll.

Explanation:

Answer 2

Number of 7th Graders = 360 - X

Explanation:

As you can see this question is not complete and lacks the essential data. But we will try to create a mathematical expression to calculate the number of students on the A honor roll which are from &th grade.

As we know:

Total number of students on the A honor roll = 360

We are asked to calculate, number of students from 7th grade on the A honor roll.

So, let's assume that "X" represents the all the students who are on the A honor roll except 7th grade.

Mathematical Expression:

Number of 7th Graders = Total number of students on the A honor roll - X

Number of 7th Graders = 360 - X

So, if you know the value of X, you can easily calculate the number of students which are from 7th grade on the A honor roll.
