the probability that an 80-year-old male in the U. S. will die within one year is approximately 0.069941. If an insurance company sells a one-year, $10,000 life insurance policy to such a person for $465, what is the company's expectation?

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.

The answer should be 5.
