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
mayadc821
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.
