Question

the regression equation y=-0.414 + 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 percent is the best prediction for the percent of people in an audience who will finish watching a documentary that is 115 minutes long?

Answer 1

Answer: 59%

Explanation:

you would plug in 115 for x making it y=-0.414(115)+106.55 giving you -47.61 then adding the 106.55 to the -47.61 giving you the final answer of 58.94 rounded to 59%..

Answer 2

The answer is: 59%.

Step-by-step explanation:

To calculate the percentage of people who have seen the movie we start from: y = -0.414x + 106.55; and of x = 115; making the appropriate substitutions we would have left: y = -0.414 (115) + 106.55; y = -47.61 + 106.55; y = 58.94, which rounded to exceed 0.5 would be 59%.

The answer is: 59%.
