Answer 1

The answer is 540.8





To find the mean all you have to do is add all the numbers together then divide that by how many numbers there are

Answer 2

The mean can be calculated by adding all of the values and dividing the sum by the number of values:

582 + 505 + 548 + 578 + 511 + 506 + 521 + 546 + 570 = 4867

There are 9 values.

4867 ÷ 9 ≈ 540.78 ≈ 540.8

The mean is about 540.78, or, rounded to the nearest tenth, 540.8.
