Statistics Question re: Mean
#1
The mean of a set of 10 numbers is 40, the mean of a set of 30 numbers is 60, and the mean of a set of 60 numbers is x. If the mean of these 100 numbers is 34, what is the value of x?

Sad

What do I do?
Don't miss out on something great just because it might also be difficult.
