Answer:
-4 to 0 (both -4 and 0 are included in the range because of the dots)
Upper is 30. Lower is 12. And the median is 22
for the first question, you get 576
for the second one you get 0.1875
Answer:
I guess that we have the linear equation:
y = 32*x
Where y is the profit, and x is the number of games sold.
Then the first step may be doing a table.
Give x different values, then find the value of y.
if x = 0
y = 32*0 = 0
if x = 1, y = 32*1 = 32
if x = 2, y = 2*32 = 64
Then the points:
(0,0) (1,32) and (2, 64) belong to this line, now we need to conect them with a straigth line and its ready.
The graph will be:
When you have parentheses in a mathematical expression, they indicate that you need to do what is inside of them first. This is actually true for any grouping symbol. You do what is grouped together first.
The parentheses themselves aren’t doing something, other than saying “Do whatever’s in me first.”
