Question

find the mean 13,15,12,20,17​

Answer 1

Mean = 13+15+12+20+17/5 = 77/5 = 15.4

Answer 2

Answer:

The mean of the given data will be$\frac{77}{5}$.

Step-by-step explanation:

The given data set is$13,15,12,20,17$.

We have to find the mean of the above data set.

• As we know, the mean of a data set is the sum of the terms divided by the total number of terms.
• The formula for mean is:

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

We are solving in the following way:

We have,

The given data set is$13,15,12,20,17$.  

Here,

$\text { Sum of terms }=13+15+12+20+17=77\\\text { Number of terms }=5$

So, the mean of the above data will be:

$\begin{aligned}\text { Mean } &=\frac{\text { Sum of terms }}{\text { Number of terms }} \\\\\text { Mean } &=\frac{77}{5}\end{aligned}$
