C, because with a class width of 10, you only need to look at how high up the y-axis the bars go (e.g the first bar for C goes up to 3), and then count how many points of data in the list fit in to that class width. So if you count 3 pieces of data, then the frequency would be 3. As the histogram shows.
Is there anything else i can go off so i may help you with the question?
Answer:
The first detail is "She always told me that "people who believe that science is the answer to everything are missing out on everything else." since science is not the answer to everything. The second one is "I noticed that cultures across the world all described dragons in similar ways. This was odd because they had no way to communicate with each other." showing that if they couldn't communicate with each other, then they might have seen/had evidence that dragons existed once if they described them in similar ways. The final one is "I saw that the Chinese calendar uses a different animal each year. Dragons are included along with eleven real animals." showing that if all the other animals were real, then it was a possibility that dragons were real once too.
The correct answer is; C. Some of them live in trash cans.
At least that's what I got on APEX.
