The correct Answer is:
To solve the problem regarding the inclusion of the number 20 in the given class intervals, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Class Intervals**: The class intervals given are 10-20 and 20-30. 2. **Understand the Definition of Class Intervals**: - In the class interval 10-20, the range includes numbers starting from 10 up to but not including 20. Therefore, this interval includes numbers from 10 to 19. - In the class interval 20-30, the range includes numbers starting from 20 up to but not including 30. Therefore, this interval includes numbers from 20 to 29. 3. **Determine the Inclusion of the Number 20**: - Since the interval 10-20 includes numbers from 10 to 19, the number 20 is **not included** in this interval. - The interval 20-30 includes numbers from 20 to 29, which means the number 20 **is included** in this interval. 4. **Conclusion**: Therefore, the number 20 is included in the class interval **20-30**. ### Final Answer: The number 20 is included in the class interval **20-30**. ---
