Question

What is the mean of x+77,x+7,x+5,x+3 and x-2

Answer 1

Answer:

Mean = sum of observations / total no. Of observations

x+77+x+7+x+5+x+3+x-3 / 5

5x+90 / 5

= x+18

Step-by-step explanation: see the formula is sum of observation by total number of observation so put their value and the answer will come

Answer 2

Given:

Given values: x+77, x+7, x+5, x+3 and x-2.

To find:

The mean of the given values.

Solution:

The mean of some given values can be found out by dividing the sum of the given values by the total number of values.

The mean of the given values in this situation will be:

Mean = $\frac{(x+77) + (x+7) + (x+5) + (x+3) + (x-2)}{5}$

On simplifying the whole equation, we have:

$= \frac{5x + 90}{5}$

On further simplifying, we get:

$= x + 18$

Thus, the mean of the given values will be x+18.
