8 numbers have a sum of 90. Whats the average number?

ehidna [41]

Answer:

$\huge\boxed{11.25}$

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.

$\frac{s}{n}$

Since we already know the sum and we know how many numbers there are (8), we can substitute inside our expression $\frac{s}{n}$ to find the average.

$\frac{90}{8}$
$11.25$

Therefore, the average of all these numbers is 11.25.
