Respuesta :

Answer:

B. 71%

Explanation:

From the question, we are given the registartion equation expressed as;

Y= -0.414 X + 106.55 where;

Y is the percent of people in the audience who finished watching a documentary

X is the length of the film in minutes

According to the question we are to find Y when X = 85 minutes

Substitute X = 85 into the expression and get Y as shown;

Y = -0.414(85) + 106.55

Y = -35.19 + 106.55

Y = 71.8

Hence the best prediction for the percentage of people in the audience who will finish watching the documentary that is 85 minutes long is 71%.
