Answer:
0.4833
Step-by-step explanation:
We want GIVEN THAT 200 pages or MORE AND RETURNED ON TIME.
Returned on time
fewer than 200 pages—— 78
200 pages ir more ——116
Returned late
Fewer than 200 pages ——15
Returned late ——31
The first table is returned on time and last row is 200 pages or more, so we take that value "116".
To get probability, we also need the total. We add up all those 4 values:
78 + 116 + 15 + 31 = 240
Thus, probability is = 116/240 = 0.4833
All you need to do is plug in the point.
y=5x+b
(-2) = 5(8) + b
-2 = 40 + b
b = -42
