Answer:
[tex]\huge\boxed{11.25}[/tex]
Step-by-step explanation:
When finding the average of a set of numbers, we
- A) Add up all the numbers
- B) Divide that sum by the total number of numbers in the data set
Let's represent this with a formula, s being the sum of all numbers, n being the total number of numbers.
[tex]\frac{s}{n}[/tex]
Since we already know the sum and we know how many numbers there are (8), we can substitute inside our expression [tex]\frac{s}{n}[/tex] to find the average.
- [tex]\frac{90}{8}[/tex]
- [tex]11.25[/tex]
Therefore, the average of all these numbers is 11.25.
Hope this helped!
