Question

Please tell me answer of this question ​

Answer 1

Step-by-step explanation:

The first 5 multiplesof 3= 3,6,9,12,15

Mean = Sum of observations /Number of observations

Mean =3+6+9+12+15/5

=45/5 =9

Answer 2

The first 5 multiples of 3 = 3, 6, 9, 12, 15.

Mean =$\frac{ Sum of observations}{ Number of observations}$

∴ Mean of the first 5 multiples of 3

$= \frac {(3+6+9+12+15)}{5}$

Then, the first 5 multiples of 3 are summed and the total value can be divided by 5 (total numbers).

$=\frac {45}{5}\\\\=9$

Thus, the mean of first five multiples of 3 is 9.
