Question

If the mean of 6,7,x,13 and 10 is 8,find range

Answer 1

Answer:

9 is the answer

Step-by-step explanation:

step:1

mean=sum of the observations/number of observations

8=6+7+X+13+10/5

8=36-x/5

step:2

find the value of X

8×5=36+X

40=36+X

40-36=X

X=4

Therefore,the value of X is 4

step:3

to find the range

highest number - lowest number = range

13-4=9

hence,the range is 9

Answer 2

Step-by-step explanation:

mean=6+7+x+13+10/5(using formula of mean)

8=36+x/5

8×5=36+x(crisscross multiply)

40-36=x

thus, the value of x is 4

Now,

To find range:

Range=Highest no. - Lowest no.

=13-4

=9

Hence, the range is 9
