Data table

F 7 4 6 2 4 2 6

X 40 41 42 43 44 45 46

Median = ((31 + 1) / 2)th item

Median = (32 / 2)th item

Median = 16th item

Arranging the discrete data in ascending order, We go get:

40, 40, 40, 40, 40, 40, 40, 41, 41, 41, 41, 42, 42, 42, 42, 42, 42, 43, 43, 44, 44, 44, 44, 45, 45, 46, 46, 46, 46, 46, 46

2x – 2/5y + 2 1/4x + 1/2y + 2y = 180

LCM = 20

40x – 8y + 45x + 10y + 40y = 3600

40x + 45x + 10y – 8y + 50y = 3600

95x + 42y = 3600

95 (6y/5) + 42y =3600

19(6y) + 42y = 3600

114y + 42y = 3600

156y = 3600

Y = 3600/156

Y = 23.08

Sub for y in eq 1

X = 6(23.08)/5

X = 27.69
