Answer 2

Answer:

Mean of first five multiples of 3 is 9

Step-by-step explanation:

First five multiple of the 3 are 3, 6, 9, 12, 15

Mean = Sum of all observation/ Total No. of observation

Total No. of observation = 5

Sum of all observation = 3 + 6 + 9 + 12 + 15

Mean = (3 + 6 + 9 + 12 + 15)/ 5 = 45/5 = 9.

Mean of first five multiples of 3 is 9
