(4, 4, 5, 7)

If you are asking to use each of those 4 numbers, than we would simply say there are 4 choices for the first digit, 3 for the second etc. and there would be 4! possible numbers, or 24 of them. Here they are Think of each one of the entries as a number. This was done for you with the program Mathematica. {{2, 3, 4, 5}, {3, 2, 4, 5}, {4, 2, 3, 5}, {2, 4, 3, 5}, {3, 4, 2, 5}, {4, 3, 2, 5}, {5, 3, 2, 4}, {3, 5, 2, 4}, {2, 5, 3, 4}, {5, 2, 3, 4}, {3, 2, 5, 4}, {2, 3, 5, 4}, {2, 4, 5, 3}, {4, 2, 5, 3}, {5, 2, 4, 3}, {2, 5, 4, 3}, {4, 5, 2, 3}, {5, 4, 2, 3}, {5, 4, 3, 2}, {4, 5, 3, 2}, {3, 5, 4, 2}, {5, 3, 4, 2}, {4, 3, 5, 2}, {3, 4, 5, 2}} If we can use a number more than once or not at all than that changes it. For example, you do not see 2222 above. Look at each number, let's start with 2, it is either in the first digit or not, in the second or not, in the third digit or not,and in the fourth digit or not.-. there are 2 choices for the number 2, same for 3,4,and 5. Then there are 2^4 choices for each (2^4)^4 or 16^4 possible numbers. That is much bigger than 24 as you can see. It is 65536. BUT that includes numbers such as 2 or 22 where we include 2 twice but not the other numbers, and we need to subtract those if we are talking about 4 digit numbers. That makes it a little harder! Do you seen why? Let me know if you need more help.

1,5,7,8 or 2,3,9,40 Any number which is middle number is 6. Not the mean though. It must be the mean of the numbers either side of the number you want. If you want 4 numbers, you need the 2 and a half number. For the 5 numbers you would chose the 3rd number

-125

It is the central number in the ordered set. To find the median of a list of numbers, you have to put the numbers from least to greatest and then count in an equal number from each side. For n data values, the median will be the ordinal number (n+1)/2 For even numbers of values, it is the average of the 2 middle numbers. Example : 1 2 4 4 5 6 7 7 7 the median is 5 1 2 4 4 4 5 6 7 7 7 the median is 4.5 (4 + 5) / 2

The mean is 5.

The answer is 5.

The mean is the same thing as average. To get the mean you add together all of the numbers in the set. Then, you divide by the total amount of numbers that were added to get the mean/average. Example: Find the mean of 5, 4, 6, 3, and 2. 5+4=9+6=15+3=18+2=20 1 2 3 4 5 (There are a total of five numbers in the set.) 5 4 6 3 2 - Numbers of the set. 20 (Sum of all numbers in the set) Divided by: 5 (Amount of numbers in the set) equals: 4 The mean (or average) of 5, 4, 6, 3, and 2 is 4.

It is (2 + 6 + 9 + 4 + 4)/5 = 25/5 = 5

5 + 3 + 7 + 3 + 2 = 20/5 = 4 The mean of the numbers is 4.

1+2+3+4+5=15/5=3

Add up the numbers and divide this total by the number of numbers. For example, the mean of the five numbers 1, 4, 2, 6, 2 is: (1 + 4 + 2 + 6 + 2) / 5 = 15 / 5 = 3.

First, you add up 3, 6, 5, 4, and 2. Which is 20. Then, you had 5 numbers, so divide 20 by 5. Which equals 4. That is your mean, which is basically an average of many numbers.

Add all the numbers together and divide by that total by the numbers. For example: 2 + 3+ 2+5 = 12 . There are 4 numbers ( 2, 3, 2, 5) So 12 divided by 4 = 3. The mean is 3.

add all of them up and divide by amount of numbers eg 1 2 3 4 5 1+2+3+4+5 / 5

The symbol for the arithmetic mean (average) of a group of numbers. The pronunciation is 'x bar'. If the set of numbers can be represented by (2, 3, 4, 4, 5), then the mean = (2+ 3+ 4+ 4+ 5)/5 = 3.6. So xbar = 3.6.

1, 5, 5, and 5 5+5+5+1=16/4=4 5-1=4
