Step-by-step explanation:

Answer 2

Answer:

16.5

Step-by-step explanation:

We know that mean of a collection of data is = sum of data points / number of data points.

Here we have to find the mean of first ten multiples of 3. The first ten multiples of 3 are : 3 X 1 = 3

                               3 X 2 = 6

                               3 X 3 = 9

                               3 X 4 = 12

                               3 X 5 = 15

                               3 X 6 = 18

                               3 X 7 = 21

                               3 X 8 = 24

                               3 X 9 = 27

and                          3 X 10 = 30

Therefore, mean

=>   $\frac{3+6+9+12+15+18+21+24+27+30}{10}$

=>  $\frac{165}{10}$

=>  16.5

Thus the mean of the first ten multiples of 3 is 16.5
