Question

Find the mean of all factors of $10$?

Answer 1

Compute the required mean:

Factors of $10$ are: $\left\{1,2,5,10\right\}$

We know that,

$\text{Mean=}\frac{\text{Sum of all the abservations}}{\text{Total number of observations}}$

Mean calculation:

$Mean=\frac{1+2+5+10}{4}=\frac{18}{4}=4.5$

Hence, the mean of all the factors of $10$ is $4.5$.
