There are 10 students in a class: 7 boys and 3 girls.
If the teacher picks a group of 4 at random, what is the probability that everyone in the group is a boy?

A. dividing 99 by 204 will tell you that 99 out of 204 of the people were females at the action movie.

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.
