Question

What is the mean? Round to one decimal place. 1,6,2,7,9

Answer 1

Answer:

5

Step-by-step explanation:

The mean represents an average of all the numbers, so we have $\frac{sum-of-all-numbers}{total-amount-of-numbers}$. Although that may seem confusing, it's actually pretty easy.

We have a total of five numbers, which are 1, 6, 2, 7, and 9.

We add these numbers up to find the sum, so 1 + 6 + 2 + 7 + 9 = 25

So our final answer will be $\frac{25}{5}$ which can be simplified to 5.
