Simplify both sides:
x
—- = -9
4
now isolate the variable (x):
x= -9 • 4
x= -36
Median is the middle number. Ex:
1,3,5,7,10,13,14
The middle number is 7 because there is three numbers on either side of 7. The median would be 7.
The mean is when you add up all of the numbers and divide by the number of numbers. For example, 1,3,5,7,10,13,14
You add all of them. 1+3+5+7+10+13+14 equals 53. Then divide 53 by 7 because there are seven digits.
Median equals 7.57142857
