Find the mean of the following data set.
42, 45, 58, 63
52
42
47

~49.9

Step-by-step explanation:

To get the mean, we must add all the numbers then divide by the amount of numbers there were.

42 + 45 + 58 + 63 + 52 + 42 + 47 = 349

Since we have 7 numbers we can do

349/7 ~ 49.9

49.8 (50 if rounded to the nearest ones place)

Step-by-step explanation: First, let's put the number from greatest to least...and we also have to add all the numbers...

42 + 42 + 45 + 47 + 52 + 58 + 63 = 349

Lastly, we have to divide the total by how many numbers there are on the data set...there's 7

349 ÷ 7 = 49.8 (50 if rounded to the nearest ones place)

Therefore, the mean is 49.8 or 50, I hope this helps!
