1. The problem involves interpreting a histogram that shows the number of whale sharks tagged in different length intervals (in feet). 2. The histogram intervals and counts are: - 0-4 feet: unknown - 5-9 feet: unknown - 10-14 feet: unknown - 15-19 feet: 8 sharks - 20-24 feet: unknown - 25-29 feet: unknown - 30-34 feet: unknown - 35-39 feet: unknown - 40-44 feet: unknown - 45-49 feet: unknown 3. The questions and answers given are: - How many sharks were between 15 and 19 feet long? 8 - How many sharks were between 5 and 14 feet long? 10 - How many sharks were less than 20 feet long? 20 - How many sharks were at least 20 feet long? 28 - How many whale sharks did the marine biologist tag? 48 - How many sharks were not between 30 and 40 feet long? 38 4. To verify and understand these answers, note that: - "Between 15 and 19 feet" corresponds to the 15-19 interval, which has 8 sharks. - "Between 5 and 14 feet" includes 5-9 and 10-14 intervals, totaling 10 sharks. - "Less than 20 feet" includes 0-4, 5-9, 10-14, and 15-19 intervals, totaling 20 sharks. - "At least 20 feet" includes all intervals from 20-24 upwards, totaling 28 sharks. - Total sharks tagged is the sum of all intervals, 48. - "Not between 30 and 40 feet" means all sharks outside 30-34 and 35-39 intervals, totaling 38 sharks. 5. These answers are consistent with the histogram data and the total count. Final answers: 1. 8 2. 10 3. 20 4. 28 5. 48 6. 38
