Answer:
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.
Since we <u>already know the sum</u> and we <u>know how many numbers there are</u> (8), we can substitute inside our expression to find the average.
Therefore, the average of all these numbers is 11.25.
