Question

6.Find the mean of the first 5 multiples of 3.

Answer 1

Step-by-step explanation:

Mean =

$\sf \dfrac{sum \ of \ quantities}{ number \ of \ quantities}$

$\sf \dfrac{3+6+9+12+15}{5} = \dfrac{45}{5} = 9$

Mean = 9

Answer 2

First 5 multiples of 3 are 3, 6, 9, 12, 15

Mean is 3 + 6+ 9 + 12+ 15/5 = 45/5 = 9

Thus mean = 9
