Hi <span>Bladen8960
So the only numbers that matter are the classes. So let's write it out 30, 60, 60, 60, 60, 60, 60, 60, 60, 70, 100, 100, 100, 100. OK so average is mean so to find mean we add all the classes then divide by how many their are so, adding them all together we get 880 students can go into each classroom so now we divide that by 14 how many classes their are which gives us about 62.
If I'm wrong I'm sorry but I hope this helps!</span>
The answer is b.
This is because the line is sloping downwards, and so y = -1
Factors are: 0, 1, 2, 4, 8, 16
Wait so are the sides of the octagon 9 inches each or do we have to find that?
