(Examples: miles per hour, cost per 1 thing, etc.)
Find the mode of this data set:
0, 4, 5, 5, 8, 4, 7, 4
The mode is 4.
(4 appears more than any other number in this data set)
How do you find the area of a triangle?
Multiply the base by the height and then divide by 2
(or do 1/2 x base x height)
What is the difference between an expression and an equation?
