algebra and math are two completly different things there is a lot of differences
9,000 - all the numbers between 1,000 and 9,999 inclusive. * * * * * NO. Those are PERMUTATIONS, not COMBINATIONS. Also, the question specified 4 digit combinations using 4 digits. The above answer uses 10 digits. If you start with 4 digits, you can make only 1 combination.
For some information, see this link What is circular permutation It goes to another wiki answers article that I just got done writing, and it is both a description of circular permutations and an explanation of how to compute them. I am going to make the assumption that you already know what permutations are in general, otherwise you wouldn't be asking for the differences between the two. Permutations are just ordered arrangements of a set or of a subset of elements. By : Jhensby
100. Don't forget the 00 combination. Otherwise think of all numbers between 1 and 99 with all single digits have a zero in the first column (e.g. 1 = 01) * * * * * No, that is the number of permutations! As far as combinations are concerned, 23 is the same as 32. So, you have 10*9/2 = 45 combinations.
A permutation is an arrangement of objects in some specific order. Permutations are regarded as ordered elements. A selection in which order is not important is called a combination. Combinations are regarded as sets. For example, if there is a group of 3 different colored balls, then any group of 2 balls selected from it will be considered as a combination, whereas the different arrangements of every combination will be considered as a permutation.
If all numbers can be used as many times as wanted then there are 109 = one billion combinations. If each number can be used only once, there are 10!/(10-9)! = 10!/1! = 10! = 3628800 combinations. * * * * * Clearly answered by someone who does not know the difference between PERMUTATIONS and COMBINATIONS. The combination 123456789 is the same as the combination 213456789 etc. All in all, therefore, there are only ten combinations which use each digit at most once.
Genetic variation, which is the differences in DNA sequences among individuals, allows for differences in inherited traits between individuals. This variation is the result of mutations, genetic recombination, and other processes that create unique combinations of genes in each individual. These genetic differences are responsible for the individuality and diversity seen within a population.
A harder version of algebra 1
algebra 1a is the first part of algebra 1 and algebra 1b is the second part. :)
Algebra 1 is a class/course that is on a higher level than Algebra.
I suspect that you want permutations rather than combinations. The permutation ABC is different from ACB, but they are both the same combination. There are 26*26*26*10*10 or 1,757,600 possible permutations of 3 letters followed by 2 numbers. But there are ten ways of arranging 3 letters and 2 numbers: eg LLLNN, LNLNL etc. All in all, therefore, 17,576,000 permutations. However, some letters are not used so as to avoid confusion between letters and numbers: eg 0 and O. Also, some sequences are not used because they form (or suggest) inappropriate words.
Given that 'ten different numbers' is all of them.. then including 0000, there will naturally be 10,000 combinations.* * * * *" ... there will naturally be 10,000" only if you don't know the difference between permutations and combinations.Orders do not affect combinations so that 1234 is the same as 4321, 1432, etc. The number of 4-digit combinationsis (10*9*8*7)/(4*3*2*1) = 210
