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

Number of 7th Graders = 360 - X

Step-by-step 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.

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.
