Find the mean of this set of numbers.
Lilit [14]
The answer would C. You must remember for the mean you need to add up all of the numbers, then divide the answer by the number of numbers you have.
Ex:
5,3,7,2,1
All of these numbers added up together is 18.In order to find out the mean, we need to divide the answer(18) by 5 because there are 5 numbers.
Hope this helps!
