Question

Find the mean of all factors of $10$.

Answer 1

Find the mean of all factors of $10$

The factors of $10$ are $1$, $2$, $5$ and $10$

$\mathrm{Mean}=\frac{\mathrm{Sum}\mathrm{of}\mathrm{terms}}{\mathrm{Number}\mathrm{of}\mathrm{terms}}$

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

$\Rightarrow Mean=\frac{18}{4}$

$\therefore Mean=4.5$

Hence, mean of factors of $10$ is $4.5$
