12. The median of observations 12, 14, 18, x + 2, 22, 25, 35, 41 arranged in ascending order is . Find the value of x?

=20

Step-by-step explanation:

if 12, 14, 18, x + 2, 22,25 ,35, 41

we r going to get the number which is before and after the the unknown number

18 is the one before the number

22 is the one after the number

x + 2= 22

x+ 2 -2 = 22- 2

x + 0 =20

x = 20

or

we make our 18 equalling to x

18 =x

x+ 2

18 + 2

= 20

70

step-by-step explanation:

2*5=10

4*15=60
