Answer 1

Answer:

=10+20+30+40+50+60+70+80+90+100/10

=550/10

=55

Average = 55.

Answer 2

Given,

10 20 30 40 50 60 70 80 90 100​

To Find,

The average =?

Solution,

We can solve the question as follows:
It is given that we have to find the average of the numbers 10, 20, 30, 40, 50, 60, 70, 80, 90, 100.

The average of a given set of observations is given as the sum of the observations divided by the total number of observations.

$Average = \frac{Sum\: of\: all\: observations}{Total\: observations}$

Here,

$Sum\: of\: all\: observations = 10 +20+ 30 +40+ 50+ 60+ 70+ 80+ 90+ 100= 550$

$Total\: number\: of\: observations = 10$

Therefore,

$Average = \frac{550}{10}$

              $= 55$

Hence, the average is equal to 55.
