A relation is a function if you associate exactly one output for every input. This means that, when you choose a value for x, there must be only one correspondent value for y. This only happens in the top-right parabola.
The mean is the average of the numbers. To obtain it, you add all the numbers together and divide by the number of numbers. So:
8+3+3+7+4= 25
25:5= 5
So the answer is: the mean is 5.
First you have to make them to a common denominator.
5/6 7/12 7/10
50/60 35/60 42/60
from these the greatest value is 35/60 because 35 parts of 60 is bigger than the rest.
so the answer is 7/12
The median is 32; list numbers least to greatest, which ever is in the middle is the median
