All even numbers between 50 and 80 are composite.
All numbers other than 11, 13 ,17, 19 ,23,29, 31 are composite numbers. eg 10,12,14,15, are composite numbers.
All of the whole numbers between 50 and 75 are composite numbers, except 53, 59, 61, 67, 71, and 73.
Not all composite numbers are even, but all even numbers except 2 are composite.
11, 13, 17, 19, 23, 29 are the primes between 10 and 30 so the composite numbers are all the others. 12,14,15,16,18,20,21,22,24,25,26,27,28, and 30 are the composite numbers between 10 and 30.
All of those numbers are composite.
All even numbers between 50 and 80 are composite.
Not all numbers between 20 and 28 are composite numbers. 23 is a prime number.
All numbers other than 11, 13 ,17, 19 ,23,29, 31 are composite numbers. eg 10,12,14,15, are composite numbers.
All of the whole numbers between 50 and 75 are composite numbers, except 53, 59, 61, 67, 71, and 73.
The composite numbers between 30 and 40 are 32, 33, 34, 35, 36, 38, and 39.
Apart from 2, all even numbers are composite. So the question is equivalent to all even numbers between 40 and 50. And these are ... ? 42, 44, 46 and 48.
All the integers between the two.
Not all composite numbers are even, but all even numbers except 2 are composite.
All except 37.
11, 13, 17, 19, 23, 29 are the primes between 10 and 30 so the composite numbers are all the others. 12,14,15,16,18,20,21,22,24,25,26,27,28, and 30 are the composite numbers between 10 and 30.
I've found all the prime numbers...
