Answer:

27/5 or 5.4

Step-by-step explanation:

We know that, Mean =

Sum of all the numbers/ the no. of number given

Then,

3+4+5+7+8/5

=5.4

Answer 2

Answer:

The mean of the given data will be$\frac{27}{5}$.

Step-by-step explanation:

Given: $3,4,5,7,8$

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,

Given data is$3,4,5,7,8$.

Here,

$\text { Sumof terms }=3+4+5+7+8=27\\\text { Number of terms }=5$

So, the mean of the given data will be:

$\begin{aligned}\text { Mean } &=\frac{\text { Sum of terms }}{\text { Number of terms }} \\\\\text { Mean } &=\frac{27}{5}\end{aligned}$
