how to solve if 6,8,5,x,4,7,8 mean of 7 find value of x

Answer 1

Dear Student!!

Question;-


how to solve if 6,8,5,x,4,7,8 mean of 7 find value of x.

Method of Solution;-



What is Mean?

The average of a given set of numbers is called the Arithmetic mean or simply the mean of the given numbers.


Now,

Using Mean Formula!!


Mean = Sum of observations / Number Of Observations


Here, Given;

Mean of the data = 7

Observation = 6,8,5,x,4,7,8.

Now, Using mean Formula to find the value of x

Mean = Sum of observations / Number Of Observations

7 = 6+8+5+x+4+7+8/ 7

7 × 7 = 38+ x

49 = 38+x

•°• x = 49-38

= 11


Hence, Value of x for the Data = 11

Answer 2

Here is your solution

Given:-

Term are 6,8,5,x,4,7,8

Total term is 7.

Mean is also 7 (given)

We have to find value of x

We know that :-

Mean = Sum of observations / Number Of Observations

=>7 = 6+8+5+x+4+7+8/ 7

=>7 × 7 = 38+ x

=>49 = 38+x

=>x = 49-38

=>X=11

Hence

The Value of x is 11

Hope it helps you
