R MEANS RADIUS......π=22/7
πR+2R=19.02
R(π+2)=19.02
R(22+14/7)=19.02
R36/7=19.02
R=19.02 divided by 36/7
R=3.69
42 inches because I used the difference of 27 and 45 inches and got 18, which I subtracted from 60 and got 42 inches
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>
Answer:
The net profit per bike is 150-40= 120. Hence to break even, the store needs to profit more than the operating cost of the store. 3840/ 120= 32. The store needs to sell 32 bicycles each month to break even.
