8 + 10 = 18
what is the average value?
answer attempt 1 out of 2
you must answer all questions above in order to submit.

Explanation:

Step1: Recall mean formula

The mean (average) of a set of numbers $x_1,x_2,\cdots,x_n$ is $\bar{x}=\frac{\sum_{i = 1}^{n}x_i}{n}$. Here $n = 2$, $x_1=8$ and $x_2 = 10$.

Step2: Calculate sum and divide by number of values

First, we find the sum $8 + 10=18$. Then, since $n = 2$, the mean is $\frac{8 + 10}{2}=\frac{18}{2}=9$.
