Mid point is found by summation of x
Then divide by 2
And same for y
Since mid point for x is 8
So x+(-9) /2 = 8
X - 9 = 16
X=16+9
X= 25
Answer:
2z-31 = -9z+24
First, combine like terms: 11z = 55
Then, divide both sides by 11: 11z/11 = 55/11
Simplify: z=5
Step-by-step explanation:
To calculate mean you add up all the numbers you have, then divide it by the total pieces of data, for example: 2 4 3 1 = 2+4+3+1=10 10÷4=2.5
To calculate median, you find the middle number, it helps to put the numbers in order. If there are two middle numbers, add them up and divide by 2.
To calculate mode, you find the number that appears the most.

500x-y?
Well what x or y, you need that do this problem. But if not then it could be just 500- xy
