Question

find the mean of 7,19,31,43,70

Answer 1

7+19+31+43+70/5
170/5
34

Answer 2

Given: $7,19,31,43,70$

We have to find the mean of the above data.

• As we know that 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,

$7,19,31,43,70$

Here,

$\text { Sum of terms }=7+19+31+43+70=170\\\text { Number of terms }=5$

Now, the mean of the given data will be:

$\begin{array}{l}\text { Mean }=\frac{\text { Sum of terms }}{\text { Number of terms }} \\\\\text { Mean }=\frac{170}{5} \\\\\text { Mean }=34\end{array}$

Hence, we get,

$\begin{array}{l}\text { Mean }=34\end{array}$
