Answer:

(a) What is the relationship between the numbers of weeks practicing and the words per minute that can be typed? Explain.

There is no scattered plot.

(c) Paul uses the function y = 7.7x + 13.8 to model the situation. How many words per minute can Paul predict to type after 5 weeks of practicing? Show your work!!!


y = 7.7*5 + 13.8 = 52.3 words/minute

(d) What does the number 13.8 in Part (b) mean in the context of the situation?

Paul predict to type 13.8 words/minute without practicing.
