None of those numbers are composite because:in math there are composite and prime numbers.prime numbers can't be factored (have two numbers that multiply to get that number).prime numbers can only be "made" by multiplying themselves by 1.exp. only 1 x 11 gives you 11.composite numbers have factors other than themselves and 1.exp. you can get 24 by multiplying 12 x2, 8x3, 4x6, 24x1.3, 5, 7, and 11 are prime numbers.

There are many, many more composite numbers than prime numbers. For example, beyond the number 3, every other number is composite, as it is divisible by 2. Following this, every number ending with a 5 other than 5 itself is composite, as it is divisible by 5, and every third odd number is divisble by 3. There are many complicated divisibility tests for numbers above 5.

15 is a composite number - it can be divided by 3 and 5. 11, 13, 17 and 19 are all prime numbers, not composite.
Out of that list, 9 and 15 is a composite.
2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31 are prime numbers. they are not composite numbers.
The sum of 5 composite numbers can be either composite, or prime, depending on the case.
5, 11 and 17 are prime number but 9 and 27 are composite numbers
