Answer 1

Answer:

42.25

Step-by-step explanation:

42+42.5+40.5+44=169

mean = total observation / no.of observation

=169/4

=42.25

Answer 2

Answer:

The mean of the given data will be$\frac{169}{4}$.

Step-by-step explanation:

Given: $42,42.5,40.5,44$

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  is used to calculate the mean is:
• $\text { Mean }=\frac{\text { Sum of terms }}{\text { Number of terms }}$

       

We are solving in the following way:

We have,

$42,42.5,40.5,44$

Here,

$\text { Sum of terms }=42+42.5+40.5+44=169\\\text { Number of terms }=4$

So, the mean of the above data will be:

$\begin{aligned}\text { Mean } &=\frac{\text { Sum of terms }}{\text { Number of terms }} \\\\\text { Mean } &=\frac{169}{4}\end{aligned}$
