The regression equation y = –0.414x + 106.55 approximates the percent of people in an audience who finish watching a documentary, y, given the length of the film in minutes, x.

which is the best prediction for the percent of people in an audience who will finish watching a documentary that is 180 minutes long?

a. 75%
b. 67%
c. 32%
d. 26%

Option: C is the correct answer.

The best prediction for the percent of people in an audience who will finish watching a documentary that is 180 minutes long is:

                 C.    32%

The regression equation is given by:

where y denote the  percent of people in an audience who finish watching a documentary.

and x denote the length of the film in minutes.

Now, we are asked to find the value of y when the value of x is :180

when x=180 we have:

which is approximately equal to 32.

           Hence, the answer is:  32%

step-by-step explanation:

first you will have to convert 3/4 into a decimal

which is .75

then you will have to divide 1.5 by .75

which is 2

no you have to divide
