Answer:
240π
Step-by-step explanation:
Turbine blade that was 24 inches long is the radius of the circle the bug travels.
So the Circumference is = 2rπ = 2*24*π = 48π
The bug held on for 5 rotations. so the distance that the bug travels = 5*48π = 240π
Answer:

Answer:
72 inches²
Step-by-step explanation:
Let
be equal to the width of the rectangle.
Let
be equal to the length of the rectangle.

Therefore, the area of the rectangle is 72 inches².
I hope this helps!
Complete question:
One classical experiment on ESP (extrasensory perception) tests for telepathy between two participants by using five cards with different designs, all known to both participants.For each trial, the “sender” participant sees a randomly chosen card and concentrates on its design. The “receiver” attempts to guess the identity of the card.<span>Assume that each of the five cards is equally likely to be chosen.
</span>Out of 10 trials, a receiver got four cards correct. What is her success rate?<span>What is her expected rate of success, assuming she is only guessing?
answer:
</span>Success rate = 4/10 = 40%
<span>Expected success rate = 1 out of 5 correct = 20%</span>
