Answer 1

I'm not sure if this is correct, but I think you add up all the numbers, and then divide them by how many numbers there are.

Answer 2

The number is way to big lol

Answer 3

\[(74+64+90+74+92+68+71)/7=\]

Answer 4

76.1428571429

Answer 5

The answer was 28...

Answer 6

Thanks tho

Answer 7

To find the range, you have to subtract the lowest value from the highest value.

Highest value: 92
Lowest value: 68

\[92 - 68 = 28\]
