Question: the registration equation Y= -0.414 X + 106.55 approximates the percent of people in the audience who finished watching a documentary, Y, given the length of the film in minutes, X. Which percent is the best prediction for the percent of people in the audience who will finish watching the documentary that is 85 minutes long?

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%.

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
