Oh, dude, let me break it down for you. So, to find the number of groups of 6 numbers you can make from 1 to 28, you just use the combination formula, which is like 28 choose 6. That gives you a grand total of 376,740 possible groups. So, yeah, there you have it, math can be fun... sometimes.
-99
Answer is 19. Explanation: we look at the entire range 99 to 131, in smaller groups. 99 has no digit 1. 100 to 109 have nine numbers with only one "1". 110 to 119 have no numbers with only one "1". 120 to 129 have nine numbers with only one "1". 130 has one number with only one "1". 131 does not have only one "1". Total: 9 + 9 + 1 = 19
There are 33C6 = 33*32*31*30*29*28/(6*5*4*3*2*1) = 1,107,568 combinations.
25 numbers are between 1-100.
Infinitely many. In fact there are more irrational numbers between 1 and 10 than there are rational numbers - in total!
Yes, they can.
The answer is 8C6 = 8!/[6!*(8-6)!] where n! = 1*2*3*...*n So, the answer is 28.
1, 2, 4, 7, 14, 28.
1, 2, 4, 7, 14, and 28 are the numbers that match this description. Therefore, six numbers divide into it evenly.
There are 376740 such sets and you must think me crazy if you think I will list them all!
If the six numbers are all different, then the answer is 6C4 = 6*5/(2*1) = 15
There are infinitely many possible answers: 1*2*14 = 28 or 5*20*0.28 = 28
It looks like you are asking how many combinations of 6 numbers are there in the 28 numbers 1 through 28. This is known as the number of combinations of 28 things taken 6 at a time. The answer is 28!/(6!22!) (n! means n factorial, which is the product of all the integers from 1 to n). I get 376,740 if I haven't made an error in arithmetic.
Oh, dude, you're hitting me with some math, huh? Well, technically, if you're looking for 4 groups of numbers that equal 28, you could have 7, 7, 7, and 7. That's like basic math, man. But hey, if you wanna get all fancy with it, you could also do 14, 7, 4, and 3. It's all good, math is math, right?
The number 28 has 6 factors. Factors are numbers that can be multiplied together to get the original number. The factors of 28 are 1, 2, 4, 7, 14, and 28. This can be determined by finding all the pairs of numbers that multiply together to equal 28.
There are 8*7/(2*1) = 28 combinations.
Two numbers that have an LCM of 28 are 14 and 28.
