Answer:
1/2pi
Step-by-step explanation:
Since the formula for circumference is 2*pi*r and we know the R=1 so the of the whole circle is 2pi. This is a quarter of a circle so the answer is 1/2pi
7x-(x-y) = 7x - x + y = 6x + y
9a-(2b-a) = 9a+a-2b = 10a-2b

To compare ratios, write them as fractions. The ratios are equal if they are equal when written as fractions.
This is a problem in binominal probability. Either the rented film is a comedy or is not a comedy (binary outcomes). the probability that the rented film is a comedy is 52%.
You must calculate and add together three probabilities to derive a final answer:
binompdf(7,0.52,0), binompdf(7,0.52,1) and binompdf(7,0.52,2).
Can you do this? Let me know if you need further help with this problem.
