Step-by-step explanation:
Median means the middle number
number already order
Median is 4 as there are 3 numbers to left and right
4,8,12,16,20,24
4x1=4
4x2=8
4x3=12
4x4=16
4x5=20
4x6=24
Answer:
3+sqrt(13/2)
3-sqrt(13/2)
Step-by-step explanation:
2 (x-3) ^2 =13
Divide each side by 2
2/2 (x-3) ^2 =13/2
(x-3) ^2 =13/2
Take the square root of each side
sqrt((x-3) ^2) =±sqrt(13/2)
x-3 = ±sqrt(13/2)
Add 3 to each side
x-3+3 = 3±sqrt(13/2)
x = 3±sqrt(13/2)
