Residuals
a residual is the difference between the actual value and the predicted value.
suppose the regression line modeling ticket sales is y = –5.9x + 170.85, where x represents ticket price and y represents attendance.
1. what is the predicted attendance when the ticket price is $5?
2. the actual attendance was 160 when the ticket price was $5.
find the residual: – =

  1. predicted attendance: 141.35

  2. residual: 18.65

Step-by-step explanation:

1. Predicted attendance is ...

  y = -5.9·5 +170.85 = 141.35

__

2. As the problem statement tells you, ...

  actual value - predicted value = residual

  160 - 141.35 = 18.65 . . . the residual

step-by-step explanation:

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

1                     1

2                   2

2                   3

2                   4   = not 1, and 4

3                   2

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.
