Answer:
5
Step-by-step explanation:
The mean represents an average of all the numbers, so we have [tex]\frac{sum-of-all-numbers}{total-amount-of-numbers}[/tex]. 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 [tex]\frac{25}{5}[/tex] which can be simplified to 5.
