19. What is the function rule?
A van gets 22mi/gal. The distance traveled D(g) is a function of the gallons of gas used.
What is the function rule?
How far did the van travel if it used 10.5 gallons of gas?

20. True or False
Discrete data is data where numbers between two data values have meaning. Examples of discrete data are measurement, temperature, length, or weight.
