Describe how to calculate the average rate of change between two (input, output) pairs of a function. The DogHouse food truck sells hot dogs from noon until 9:00 pm or whenever they run out of hot dogs – whichever comes first. The following are the sales from yesterday.

Time12:301:303:003:455:006:157:308: 009:00
Total # of hot dogs sold156480110225317518675712
a. What was the average rate of change from 12:30 until 3:00?

b. What was the average rate of change from 5:00 until 9:00?

c. What was the average rate of change for the entire day?

d. If today they have 550 hotdogs and expect similar business, when might they predict being able to close the food truck? Explain how you made your prediction.

Write the contrapositive of the conditional statement. determine whether the contrapositive is true or false. if it is false, find a counterexample. a converse statement is formed by exchanging the hypothesis and conclusion of the conditional. a) a non-converse statement is not formed by exchanging the hypothesis and conclusion of the conditional. true b) a statement not formed by exchanging the hypothesis and conclusion of the conditional is a converse statement. false; an inverse statement is not formed by exchanging the hypothesis and conclusion of the conditional. c) a non-converse statement is formed by exchanging the hypothesis and conclusion of the conditional. false; an inverse statement is formed by negating both the hypothesis and conclusion of the conditional. d) a statement not formed by exchanging the hypothesis and conclusion of the conditional is not a converse statement. true

What is the distance between a and b? round your answer to the nearest tenth. a coordinate plane is shown. point a is located at negative 1, 5, and point b is located at 4, 1. a line segment connects the two points.
