The Stem-and-Leaf Graph shows the distance traveled by Rob's family, in
miles per day, to reach their holiday destination. What is the mean for this
data?

OA) 65 mi. per day
OB) 73 mi. per day
OC) 82 mi. per day
OD) 94 mi. per day

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.
