Six flags amusement park has found that 3/5 of its customers ride the colossus roller coaser. of these, 1/4 ride it again. what fraction of the customers ride the roller coaster twice? (show work )

It would be 1/4 because thoose peoples ride the roller coster again.

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.
