Sum = 85
Number = 5
So mean = 85/5 = 17

To find the mean of the numbers 20, 12, 20, 15, 8, 20, 12, and 10, first add them together: 20 + 12 + 20 + 15 + 8 + 20 + 12 + 10 = 117. Then, divide the total by the number of values, which is 8: 117 ÷ 8 = 14.625. Therefore, the mean is 14.625.
If you mean 20% of 15 that's 3. If you mean 20% off that's 15-3 or 12.

20 - 15/100 * 20 20 - .15 * 20 20 - 3 $17

Add up all the numbers together and then divide by 12 to find the average mean:- 68/12 = 17/3 or as 5 and 2/3
13, 15, 17, 19
10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20
If you mean 20% of 15 that's 3. If you mean 20% off that's 15-3 or 12.
13, 15, 17 and 19
The median of {10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20] is the 6th values which is 15.
10, 20, 15, 17, 13
If you mean -17 = 15n -20 then the value of n is 1/5
