Question

Find the average following set of numbers: (65,85,70,90 and 150)​

Answer 1

Concept Introduction:

Average of numbers is sum of given numbers divided by number of numbers.

Given: set of numbers: $(65,85,70,90,150)​$

To Find:

We have to find the value of, average of given numbers.

Solution:

According to the problem,

Given numbers are $65,85,70,90,150$

Number of given numbers =$5$

Average = sum of all numbers / no.of given numbers

=$\frac{ (65+85+70+90+150)}{5}$ = $\frac{460}{5} =92$.

Final Answer:

The value of average of given numbers is $92$.

Answer 2

Concept:

In mathematics, the mean of a list of data is an expression of the central value of a set of data. Mathematically, it is defined as the ratio of the sum of all data to the number of units present in the list. In terms of statistics, the mean of a given set of numerical data is also called the mean. For example, the average of 2, 3, and 4 is (2+3+4)/3=9/3 =3. So here 3 is the central value of 2, 3 and 4. So the point of the average is to find the middle value of a group of numbers.

The mean is defined as the mean value, which is equal to the ratio of the sum of the number of a given set of values to the total number of values present in the set.

Find:

We have find the average

Given:

Given data is 65,85,70,90 and 150

Explain:

Given numbers are 65,85,70,90,150

Number of given numbers =5

$average = \frac{sum \: of \: all \: observation}{no \: of \: observation}$

$average = \frac{65 + 85 + 70 + 90 + 150}{5}$

$average = \frac{460}{5}$

$average = 92$

Hence the average is 92
