1. consider this scatter plot. (a) what is the relationship between the numbers of weeks practicing and the words per minute that can be typed? explain. (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 ! (d) what does the number 13.8 in part (b) mean in the context of the situation?

(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.

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
