Question

what is the average for 10 12 14 13 10 15 11 12

Answer 1

To find the average of the numbers 10, 12, 14, 13, 10, 15, 11, and 12, you first add them together and then divide by the number of values.

1. Add the numbers:
\[
10 + 12 + 14 + 13 + 10 + 15 + 11 + 12 = 10 + 12 = 22
\]
\[
22 + 14 = 36
\]
\[
36 + 13 = 49
\]
\[
49 + 10 = 59
\]
\[
59 + 15 = 74
\]
\[
74 + 11 = 85
\]
\[
85 + 12 = 97
\]

So, the sum is 97.

2. There are 8 numbers in total.

3. Now, divide the sum by the number of values:
\[
\text{Average} = \frac{97}{8} = 12.125
\]

Therefore, the average of the numbers is **12.125**.
