Question

The mean of 8, 13, 6, 4, x ,7 ,9 ,16, 12 is (x + 3). Find the value of mean and median.​

Answer 1

Answer:

Given: mean of numbers is 8

The numbers are:7,9,x,13,6

To calculate mean we have formulation,

=(Sum of total numbers)/(count of total given numbers)

So the Mean is given that is 8 therefore,

8=(7+9+x+13+6)/(5)

8*5=35+x

40=35+x

X=40–35

[X=5]

The value of X is 5.

Answer 2

7,9,x,13, 6 are given

Then,its mean

(7+9+x+13+6)/5

But here given mean of given members is 8

So,

»(7+9+x+13+6)/5=8

»(35+x)=40

»x=40–35

x=5,Ans

Hope this helps..❤️
