Suppose the sample space for a probability experiment has 70 elements. If items from the sample space are selected without replacement, how many different ways can you select all of the items? Remember that "without replacement" means that the items are not returned to the sample space after they are chosen. Write your answer in factorial notation.

Malia is observing the velocity of a cyclist at different times. after two hours, the velocity of the cyclist is 15 km/h. after five hours, the velocity of the cyclist is 12 km/h. part a: write an equation in two variables in the standard form that can be used to describe the velocity of the cyclist at different times. show your work and define the variables used. (5 points) part b: how can you graph the equations obtained in part a for the first 12 hours? (5 points) if you can try and make this as little confusing as you can
