​

Answer 1

• As per the data given in the question, we have to find the average.

       Given data- $9,11,13,15$ and $17.$

       To find - Average=?

       Solution:-

• Average:- It is the ratio of the sum of all given numbers to the total number of items.
• It is calculated as,

       Average=Total sum of all numbers/number of items.

       So, we are using the average formula. we get,

        $\R\frac{9+11+13+15+17}{5}\\\Rightarrow \frac{70}{5}\\\Rightarrow 14.$

      Hence, the value will be $14.$

     

Answer 2

Given that:- $9,11,13,15$ and $17.$

As we have to find the average,

For, finding the average we have to sum up the given number and divide it by the total no. of items.

Therefore,

Average $=\frac{total sum}{no. of items}$

$=>\frac{9+11+13+15+17}{5}$

$=>\frac{70}{5}$

$=>14$

Hence, the average value is 14.
