(0, 0) → t = 0, w = 0 → w = 0 · 0
(1, 4) → t = 1, w = 4 → w = 1 · 4
(2, 8) → t = 2, w = 8 → w = 2 · 4
(3, 12) → t = 3, w = 12 → w = 3 · 4
<h3>Answer: w = 4t</h3>
Answer:
Connect the arcs to make a perpendicular bisector
1.5 minutes = 90 second
The probability density function is

so the probability of interest is
