Question

the following data arranged is ascending order (9,1012,13,7x,7x+1,17,17,9,21)if the median of the is 14.5 then what is the value of x
​

Answer 1

Step-by-step explanation:

median =middle term ( if n is odd)

median=sum of middle terms /2

9,10,12,13,7x,7x+1,17,17,9,21,

first arrange in ascending order

9,9,10,12,13,7x,7x+1,17,17,21

no.of terms=10(even)

7x+7x/2=14.5

14x=29

x=29/14

x=2.07

x=2
