The line plot shows the distances some students jumped during a field day competition. what fraction of the students jumped 5 1/2 feet?

To answer this question here is what you would do. I can't give you the exact answer because there is not a line plot attached.

Count the number of X's above the number 5 1/2 feet. Put this number over the total number of X's you count (including the 5 1/2s).

This is your answer when you write these 2 pieces of information in fraction form.

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.
