3.9+3.9 = 7.8
7.8 * 3.9 * 3 = 91.26
5.7 * 3.9 * 3 = 66.69
66.69 + 91.26 = 157.95
Answer is A
Answer:
No, none of the number need to be 48 for the mean to be 48. To get a mean, you add up all the number and divide it by the amount of numbers.
Example:
the mean of 10, 79, 42, 88, 19, and 50 is 48, but the actual number 48 was not part of the set.
10 + 79 + 42 + 88 + 19 + 50 = 288
288 ÷ 6 = 48
