10 11 10 y 10 8 if the mean is 10 what number could y be?

11

Step-by-step explanation:

There are 6 numbers and the mean is 10. When finding the mean, you divide the sum by the number of values.

All we need to do is find the sum and go backward.  

10*6 = 60, the sum is 60 of all the numbers, including y.

Now find the sum of the numbers excluding y, 10+11+10+8 = 49.

The sum of the numbers without Y is 49.

Subtract 60-49 to see what y is.

60 - 49 = 11

Y=11

If you don't understand why I subtracted 60 and 49, it is because all I did was take away y from the sums, therefore we can see the differences with and without y.
