It takes Ariel 60 minutes to reach the hiking team's campsite, following a
trail depicted in the graph at the right.
What is the change in the elevation between Ariel's starting point and the campsite?
A) 10 feet
B) 20 fect
C) 25 feet
D) 40 feet

I think 20

because her starting point was 5 and her ending point was 25 and the difference is 20

the correct answer is b) histograms can be used to exhibit the shape of distributions. this is because histograms count the frequency of each possible answer, so one is able to see which results are more common and which are less common.

astronomers is your final answer! : )
