Question 972137: the mean of a set of six numbers is 2 and the mean of another set of ten numbers is m. if the mean of the combined set of sixteen number is 7, find the value of m. Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! mean= total/number
total of first must be 12
total of the combined 16 must be 16*7, or 112. If we subtract the total from the first, we get 100.
Therefore, the 10 numbers must have a mean of 10, a total of 100.
