Sagot :

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!
