if I have the numbers 8,4,11,13 and need a 5th number to make my mean 10 what would the blank number be?

14

Step-by-step explanation:

If you want to solve this question, you would need to know the sum of your number right now and after you add the blank number.

First one is: 8 + 4 + 11 + 13 = 36.

Second one: Sum = mean x [how many numbers there are], which means:

sum = 10 x 5 = 50.

Then, subtract the 36 from 50, and you get the 14.
