To find the correct scatter plot, we first need to extract the data points corresponding to each instructor's lesson length and cost. The provided data can be summarized as follows:
Instructor 1: 30 minutes, $45
Instructor 2: 30 minutes, $25
Instructor 3: 45 minutes, $60
Instructor 4: 20 minutes, $35
Instructor 5: 60 minutes, $50
Instructor 6: 50 minutes, $55
Instructor 7: 60 minutes, $75
Instructor 8: 30 minutes, $50
Instructor 9: 60 minutes, $80
Now let's organize these into (x, y) format (where x = lesson length and y = lesson cost):
(30, 45)
(30, 25)
(45, 60)
(20, 35)
(60, 50)
(50, 55)
(60, 75)
(30, 50)
(60, 80)
Now we can match this list with the options given for the scatter plots:
The first option has points (25, 30), (35, 20), (45, 30), (50, 30), (50, 60), (55, 50), (60, 45), (75, 60), (80, 60) - Incorrect.
The second option has points (20, 35), (25, 30), (30, 45), (30, 50), (45, 60), (50, 55), (60, 50), (60, 75), (60, 80) - Incorrect.
The third option has points (20, 35), (30, 25), (30, 45), (30, 50), (45, 60), (50, 55), (60, 50), (60, 75), (60, 80) - Incorrect.
