Composite numbers are the opposite of prime numbers- they have more factors than just 1 and themselves. A list is unnecessary, I think. All even numbers are automatically composite because they have 2 as a factor, excluding 2. All the numbers that end in 0 and 5 are composite because they are divisible by ten or five. However, I will provide a list.
1 , 4 , 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28, 30, 32, 33, 34, 35, 36, 38, 39, 40, 42, 44, 45, 46, 48, 49, 50, 51, 52, 54, 55, 56, 57, 58, 60, 62, 63, 64, 65, 66, 68, 69, 70, 72, 74, 75, 76, 77, 78, 80, 81, 82, 84, 85, 86, 87, 88, 90, 91, 92, 93, 94, 95, 96, 98, 99, 100.
compostie
All of them except for 31 and 37 which are prime numbers
1000, 1020, 1040, 1060, 1080, and 1100
Mean average of 175, 550, 750 & 1100 (175+550+750+1100)/4 = 643.75
