mean:74.285
so this is your mean
hope it may help you

Answer 2

Answer:

The mean of the given data will be$\frac{520}{7} \approx 74.2857$.

Step-by-step explanation:

Given: $45,84,64,86,84,84,73$

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,

$45,84,64,86,84,84,73$

Here,

$\text { Sum of terms }=45+84+64+86+84+84+73=520\\\text { Number of terms }=7$

So, the mean of the above data will be:

$\begin{aligned}\text { Mean } &=\frac{\text { Sum of terms }}{\text { Number of terms }} \\\\\text { Mean } &=\frac{520}{7}\end{aligned}$

$mean=\frac{520}{7} \approx 74.2857$
