An allergy test is administered to 400 people. The results are shown in the table.

a. What probability of test subjects who test positive have the allergy? Round to the nearest hundredth.

b. What probability of test subjects who do not have the allergy test negative? Round to the nearest hundredth.

Sorry i really need my points

No i refuse to tell you the answer but the estimate is 10

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
