Question

question

9 + 8 + 1 = 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 $n = 3$, $x_1=9$, $x_2 = 8$, $x_3=1$. First, find the sum.
$9 + 8+1=18$

Step2: Calculate the mean

Since $n = 3$, the mean $\bar{x}=\frac{18}{3}=6$.

Answer:

6
