Hello.
The symbols | | mean the absolute value, which is keeps the numbers postive.
Of the answers shown, the correct answer is {-8, 8) because |-8 + 2| = 10, because of the absolute value symbols | |. (Also |8 + 2| of course equals 10.)
To find the average, find the mean: add all the numbers together and divide by the number there is.
First add all the numbers together:
39 + 43 + 28 + 36 + 29 = 175
Next, divide 175 (the total) by 5 (because there are 5 numbers)
175/5 = 35
35 is your average.
hope this helps
