Question

Q18. If the median of data 12,24,30,35,37,40,3 x 3 x + 4,52,57,59,62,67,70 which are arranged in ascending order is
47 then find the value of x.​

Answer 1

Step-by-step explanation:

n= 14 even

median of even = 1/2 ( n/2 + n/2+1) th term

47 = 1/2 (7th term + 8 th term)

47 =1/2 (3m+3m+4)

94= 6 m +4

90 = 6 m

m= 90/6

m= 15
