Answer 2

The mean of all factors of 30 is 9.

Step-by-step explanation:

We have,

Number = 30

To find, the mean of all factors of 30 = ?

The factor of 30 are:

1, 2, 3 , 5, 6, 10, 15 and 30.

The mean of 1, 2, 3 , 5, 6, 10, 15 and 30.

Here, number of observations = 9

∴ Mean = $\dfrac{Sum of observations}{Number of observations}$

$=\dfrac{1+2+3+5+6+10+15+30}{8}$

$=\dfrac{72}{8}=9$

Hence, the mean of all factors of 30 is 9.
