PLEASE HELP!!!!!

Answer 1

In a random sample of students at a middle school 24 wanted to change the mascot and 30 wanted to keep the current mascot.

So total number of students in the sample = 30+24= 54

Number of students in random sample who wanted to keep the current mascot = 30

So out of 54 students 30 wanted to keep current mascot.

So for 1140 students = (30/54)*1140  = 633 students want to keep the currect mascot.

Answer: Third option 633 students.

Answer 2

D is the best answer because when you subtract you get close to 950.
