What is the difference between the multiplication rule for independent versus dependent events?
Given two events, A and B, Pr(A and B) = Pr(A)*Pr(B) if A and B are independent and Pr(A and B) = Pr(A | B)*Pr(B) if they are not.

Describe the difference between a single trade discount versus and discount series and give an example
Are mass and weight the same or same thing?
They are quite different things. The relationship between the two is: weight = mass x gravity.For more information about the difference between the two, check the Wikipedia article on "Mass versus weight".
What type of motion is represented by the graphs describes by distance versus time and distance versus time squared?
vt-v2
Area under the velocity versus time graph?
Area under velocity versus time graph(between two given instances of time i.e. two points on time axis) gives the displacement of the body( whose graph was plotted) between those two instances i.e. in that time interval. Area under velocity time graph can be found from definite integration if the graph is a curve. Note: Area under velocity versus time graph gives displacement not distance covered by body. Note: Area enclosed between the plotted curve and time axis is taken. For convenience time should be taken in the x-axis.
