1. The problem asks to identify composite numbers in the given sets. 2. Composite numbers are numbers greater than 1 that have more than two factors. 3. Prime numbers have exactly two factors: 1 and themselves. 4. For the first set: 10, 11, 15, 17, 24, 39, 48, 41 - Composite numbers are 10, 15, 24, 39, 48 - Prime numbers are 11, 17, 41 5. For the second set: 91, 98, 81, 101, 112, 150, 121, 131 - Composite numbers are 91, 98, 81, 112, 150, 121 - Prime numbers are 101, 131 6. For the third set (box prime numbers): 12, 17, 13, 28, 31, 34, 37, 47 - Prime numbers are 17, 13, 31, 37, 47 7. For the fourth set (box prime numbers): 71, 51, 95, 67, 75, 34, 99, 101 - Prime numbers are 71, 67, 101 8. Least prime number is 2. 9. Greatest three-digit even composite number is 998 (since 1000 is not composite, 998 is even and composite). 10. Numbers neither prime nor composite are 0 and 1. 11. Composite numbers from 1 to 10: 4, 6, 8, 9, 10 12. Composite numbers from 11 to 20: 12, 14, 15, 16, 18, 20 13. Composite numbers from 21 to 30: 21, 22, 24, 25, 26, 27, 28, 30 14. Composite numbers from 31 to 40: 32, 33, 34, 35, 36, 38, 39, 40 15. Composite numbers from 41 to 50: 42, 44, 45, 46, 48, 49, 50 Final answers: 1. Composite numbers: 10, 15, 24, 39, 48 2. Composite numbers: 91, 98, 81, 112, 150, 121 3. Prime numbers: 17, 13, 31, 37, 47 4. Prime numbers: 71, 67, 101 5. Least prime number: 2 6. Greatest three-digit even composite number: 998 7. Numbers neither prime nor composite: 0, 1 8. Composite numbers 1-10: 4, 6, 8, 9, 10 9. Composite numbers 11-20: 12, 14, 15, 16, 18, 20 10. Composite numbers 21-30: 21, 22, 24, 25, 26, 27, 28, 30 11. Composite numbers 31-40: 32, 33, 34, 35, 36, 38, 39, 40 12. Composite numbers 41-50: 42, 44, 45, 46, 48, 49, 50
