Answer:
0.0713 = 7.13% probability that the result is positive.
Step-by-step explanation:
Probability of a positive test:
91% of 1/650(has the disease).
7% of 1 - 1/650 = 649/650(does not have the disease). So

0.0713 = 7.13% probability that the result is positive.
Answer:
π = C/2r
Step-by-step explanation:
C=2πr
C/2r = π
Slope is (24--31)/(-6-5) = 55/-11=-5
y-24=-5(x--6)
y-24=-5x-30
y=-5x-6
