Cut one granola bar into 4 parts. Take one granola bar and one piece of the cut bar.
slope = change_in_Y / change_in_X = (8 - 3) / (5 - -4) = 5/9
The symbol for the arithmetic mean (average) of a group of numbers. The pronunciation is 'x bar'. If the set of numbers can be represented by (2, 3, 4, 4, 5), then the mean = (2+ 3+ 4+ 4+ 5)/5 = 3.6. So xbar = 3.6.
She has 3 bars of chocolate that each have 4 pieces so 3 x 4 = 12 (or 4 + 4 + 4 = 12)She eats 5 pieces from that 12 so all you do is subtract 12 - 5 to get your answer.
no Try visualizing a candy bar that you really really like. If you cut it into 9 pieces, would you rather have 4 pieces or 5 pieces? 5, right? Because it's more and you want as much of the candy bar as possible, right? So if you think of it that way, it's clear to see/taste, that 4/9 is smaller than 5/9. NO IT IS NOT. 4/9 is clearly smaller than 5/9.
