Answer 2

Answer:

The required average of the given numbers $40,50,60,70,80,90,100$ is $70$.

Step-by-step explanation:

Concept: The ratio of the sum of the values in a particular set to all the values in the set is the mean value, which is the definition of the average.

Given: The numbers are $40,50,60,70,80,90,100$

To find: The objective is to find out the average of the given numbers.

Solution:

The given numbers are $40,50,60,70,80,90,100$

We know, Average = Sum of all observations/total observations

Sum of all numbers

$=(40+50+60+70+80+90+100)\\=490$

Total observation$=7$

Average:

$=\frac{490}{7} \\=70$

Therefore, the required average of the given numbers is $70$.
