53 and 55.
It is: 55C6 = 28,989,675
I am not stupid enough to try and list them since there are 55*54*53*52*51*50/(6*5*4*3*2*1) = 28,989,675 combinations. nPr=permutation while nCr=combination. The question is how many combination of 6 are there in 55 numbers. So the answer should be based on the formula: nPr = n!/(n-r)! where ! is factorial and nCr = nPr/r! = n!/{(n-r)*r!} ; So using the formula should look likr this 55C6 = 55!/{(55-6)!*6!} = 55!/(49!*6!) = 28,989,675
You know that sum of the first n whole numbers is n(n+1)/2. ( it is the same as the first n natural numbers since the zero does not add anything) So lets say you want the sum of all the whole numbers between 3 and 10. ( I made it easy to illustrate the idea.) The sum of the whole numbers between 0 and 3 is 3(4)/2=6 The sum of the whole numbers between 0 and 10 is 10(11)/2=55 So the sum of the whole numbers between 3 and 10 is the (sum of the whole number between 0 and 10) -(sum of whole numbers between 0 and 3) which is 55-6=49 So in general, for whole numbers m and n with m
What numbers are between 55 and 101 of multiples of 3, 5, and 6
72 and 90
50. 51. 52. 53. 54. 55. That is 6 numbers.
what numbers between 55 and 101 that has a multiple of 2,8,10
The prime numbers between 55 and 70 are: 59, 61 and 67
There are 6 numbers between 1 and 70 that are divisible by 11. These numbers are: 11; 22; 33; 44; 55; 66.
The triangular numbers between 1 and 66 are: 3, 6, 10, 15, 21, 28, 36, 45 and 55.
The prime numbers between 45 and 55 are 47 and 53.
55. To find a number halfway between two numbers on the number line, add the two numbers together and divide by 2, so (82 + 28)/2 = 110/2 = 55. Check the answer: 55-28 = 27, and 82-55 = 27.Example: what is half way between 4 and 6 (the obvious answer is 5), but work it through: (4+6)/2 = 10/2 = 5.
The prime numbers between 30 and 55 are 31, 37, 41, 43, 47, and 53.
The triangular numbers between 1 and 100 are: 1, 3, 6, 10, 15, 21, 28, 36, 45, 55, 66, 78, 91.
Between 1996 and 2014 the most common numbers between 1 and 55 drawn in lotteries were 4, 48, 10, 39, 2, and 5. However, the frequency of these numbers being drawn are not significantly more likely to be drawn than any others.
