How many different 6 digit combinations can be made from 10 numbers if you can repeat a number?
There are just 5,005.There are 10C6 = 210 combinations with 6 different numbers.There are 10C5 = 252 combinations with 5 different numbers. One of these needs to be duplicated and the one to be duplicated can be chosen in 5 ways so there are 1260 of these.There are 10C4 = 210 combinations with 4 different numbers. Either one of them appears three times or two are doubled. That can be done in 10 ways so there are 2,100 of these.There are 10C3 = 120 combinations with 3 different numbers. Either one of them appears 4 times, or one twice and another three times, or all three appear twice. That can be done in 10 ways so there are 1,200 of these.There are 10C2 = 45 combinations with 2 different numbers. Either one of them appears 5 times, or one twice and another four times, or both three times. That can be done in 5 ways so there are 225 of these.There are 10C1 = 10 combinations with just 1 number repeated six times.Add these together.
Is -0.45 a rational or irrational number?
-.45 is rational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
How many subsets containing an odd number of elements does a set with 10 elements have?
We are looking for all sets with an odd number of elements in them. To find this we can use combinations. Adding up the odd combinations will total the subsets containing an odd number of elements.nCr where n=10 and r=(1,3,5,7,9)10C1 + 10C3 + 10C5 + 10C7 + 10C9 = 512.You could also take the total number of elements (2^10) and subtract all sets containing an even number of elements.nCr where n=10 and r=(0,2,4,6,8,10)1024-(1+45+210+210+45+1)=512

What is the median for the set of data for 45 58 19 68 13 44 39?
Once you put the numbers in order, the median is the middle number or the average of the 2 middle numbers. 13, 19, 39, 44, 45, 58, 68. 44 is the number in the middle, so 44 is the median.
