What is the ratio of the number of one-digit prime numbers and the number of one-digit composite numbers?
The ratio of the number of one-digit prime numbers to the number of one-digit composite numbers is one to one. The one-digit prime numbers are 2, 3, 5, and 7. The one-digit composite numbers are 4, 6, 8, and 9. Therefor, the ratio is 4:4, which simplifies to 1:1.
What is the sum ratio of the number of one digit prime numbers and the number of one digit composite numbers?
There are four of each.
Ratio of square numbers to numbers with 4 factors?
As N approaches infinity the ratio of squares less than N to numbers with 4 factors less than N approaches 0. This means that in the customary way of defining it, the ratio you're interested in is 0 (although that should be taken with a grain of salt - it certainly doesn't mean that there are 0 square numbers). The number of squares less than N is approximately √N. Rather than calculating the ratio we're interested in, we're going to calculate a calculate a ratio guaranteed to be greater: the ratio of squares to numbers that are twice a prime number (which are some, but not all, of the numbers with 4 factors). There are approximately N/ln N prime numbers less than N, by the prime number theorem. So there are N/(2 ln N/2) prime numbers less than N/2, which can be doubled to get a number less than N that's twice a prime number. The ratio is therefore √N(2 ln N/2)/N, which is O(ln N/√N). √N grows much faster than ln N, and in the limit this ratio will get close to zero. So the ratio we're actually interested in, which is even less than this ratio, will also approach zero.
What are all the prime numbers 1000-1500?
the answer could have something to the ratio of prime numbers between 0 and 9 to the the number of prime primes between 9 and 625 and the number of primes between the square 25x25. Hint: the are 9 primes between 0 and 25. There are 114 primes between 25 and 625. There is a square number somewhere near 1000. 961 which is the Mercienne prime number 31 squared. without giving the answer away, by dividing 625 by 9 we get the ratio 12.6666667 or 12 and 2 3rds. this is one of many ratio to help find how many prime numbers within a given range. once the precise ascending pattern of prime numbers is discovered then any prime number to infinity can be calculated and identified disclosure: this information is designed to provide food for thought on the matter of the question above and is not a precise answer.
What is the ratio of number of primes and numbers of composites between 20 and 40?
The prime numbers between 20 and 40 are 23, 29, 31 and 37 that is 4 out of 20 or 1 to 5
