Answer:
How to Find the Median
Step-by-step explanation:
To find the Median of a number you can put the numbers in order and cross each one until you get a one number
Example:
1,2,3,4,<em>5</em>
The Number 3 that is bolded will be the Median
But if there is two numbers left which you can't cross out
you will have to divide those two numbers and then divide it by 2
Example:
1,2,3,4,5,6,7,8
The number 4 and 5 that is bolded will be divided
Example:
(4÷5)÷2

Answer:
20.
Step-by-step explanation:
2x + x - y^2; x = 8 and y = 2.
2(8) + 8 - (2)^2
= 16 + 8 - 4
= 24 - 4
= 20.
