if the mean of a distribution is M=48, what is the new mean if each score is divide by 3/4, and then 35 is subtracted from each

mmmmhhh?

if the mean is 48, that means the average number was 48
so we divide each by 48, then subtract 35 to get 1

so what is the average of a bunch of 1's ??
then new mean is 1

illustration: lets simplify the question
you are given the numbers 12, 18, and 24
the mean would be 18
let's divide each number by 2, then subtract 3
12 ---> 3
18 ---> 6
24 ---> 9

new average (mean) = 6
