40 numbers.
They are 150, 152, 153, 154, 155, 156, 158, 159, 160, 161, 162, 164, 165, 166, 168, 169, 170, 171, 172, 174, 175, 176, 177, 178, 180, 182, 183, 184, 185, 186, 187, 188, 189, 190, 192, 194, 195, 196, 198, 200
Listing and striking off multiples is so elementary. Suppose the range was much larger. Suppose u want to give it to a computer.
We must use the Inclusion and Exclusion formula
79
Out of those 100 numbers, 21 of them are prime numbers, so the remaining (100 - 21) = 79 are composite.
All numbers between 1-200 except:2,3,5,7,11,13,17,19,23,29,31,37,41,43,47,53,59,61,67,71,73,79,83,89,97,101,103,107,109,113,127,137,139,149,151,157,163,167,173,179,181,191,193,197,199.
The primes between 150 and 200 are: 151,157,163,167,173,179,181,191,193,197, and 199
201,202,203,204,205,206,207,208,209
There are approx 5.709*10^45 possible sets of numbers that can be made out of the composite numbers in 1 and 200.
79
For any integer greater than 5, where the units digit is 5 then that number can be expressed as the product of n and 5. As such, the number is composite. Therefore all numbers in the range 150 to 200 that have a units digit of 5 are composite,.
Out of those 100 numbers, 21 of them are prime numbers, so the remaining (100 - 21) = 79 are composite.
They are all the numbers that have more than two factors in them.
203,207,211,213,217.
4, 8, 10, 20, 25, 40, 50, 100, 200 are the composite factors of 200.
All numbers between 1-200 except:2,3,5,7,11,13,17,19,23,29,31,37,41,43,47,53,59,61,67,71,73,79,83,89,97,101,103,107,109,113,127,137,139,149,151,157,163,167,173,179,181,191,193,197,199.
The primes between 150 and 200 are: 151,157,163,167,173,179,181,191,193,197, and 199
They are all the integers from 2 to 200.
Composite numbers are those which are divisible by at least one positive integer besides one and itself. Some composite numbers between 0 and 200 include 4, 6, 8, 9, and 10.
