Question

The average of 13 , 20 , 7 , x and 10 is 13 . ... The value of x is​

Answer 1

Step-by-step explanation:

13+20+7+10+x/5. (average=sum of total/total no)

50x/5=13×5

10x=65

x=15

Answer 2

Answer:

The value of x = 10

Step-by-step explanation:

Given data 13, 20, 7, x, 10  

Average of the given observations = 13

here we need to find value of x

Average of data = sum of the observations /number of observations

                           = 13+20+7+ x+10 /5

                           = (50+x)/5

from given data   $\frac{50 + x}{5} = 13$

                            50+x = 60

                                  x = 60-50 = 10

                                  x = 10
