Hello.

To find the mean of a set of numbers, add all of the numbers together, then divide by the amount of numbers.

There is 5 numbers.

(68 + 75 + 72 + 90 + 80) / 5

All numbers added together is 385.

385 / 5 = 77

The mean is 77.
The answer is 77

The mean is all the numbers added together and divided by how many numbers they’re are.
Take 68,75,72,90,80 and add them and you get 385. Then divide by 5 because there are 5 numbers and you get 77.
