Question

The mean of 20,12,29,15,49

Answer 1

To find the mean of this set of data you must add all the numbers together, then divide by the numbers that you have. Since you have 5 numbers you would divide by 5 after adding them together. 

1st: ADD!!
20 + 12 + 29 + 15 + 49 = 125

2nd: divide by 5!
125 ÷ 5 = 25

So the mean of this data set is 25. 

Good Luck! :)
