In a coordinate algebra class 22 students where male and 10 students where female. 11 guys and 4 girls passed the EOCT. If a person is chosen at random from the class what is the probability of it being a girl OR a person that did not pass?

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.
