How many 4 digit numbers can be formed using 2 3 4 and 5 as many times as possible?
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.
4 numbers with a median of 6?
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
What is the median of a list of numbers?
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
A sentence using the word mean?
Mean, adj. not nice: The bully was mean to all the other children.Mean, noun, the average of several numbers: 4 is the mean of the numbers 3, 4, and 5.
How do you work out the mean in maths?
add up all the numbers you have then divide by the amount of numbers you haveThe mean is the same as the average. You must add up all the data, then divide by the number of data entries you added. E.g. 3+5+2+6+4=20 then 20 divided by 5 = 4, so in this case 4 is the mean.
How do you get a mean?
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.
What is the mean of these numbers 2 6 9 4 4?
The answer is 5.
What is mean of these numbers 2 6 9 4 4?
It is (2 + 6 + 9 + 4 + 4)/5 = 25/5 = 5
What is the mean of 5 3 7 3 2?
5 + 3 + 7 + 3 + 2 = 20/5 = 4 The mean of the numbers is 4.
What is the mean for the numbers 1 2 3 4 and 5?
1+2+3+4+5=15/5=3
What is the mean for 3 6 5 4 2?
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.
What does a x with a line over it mean?
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.
Mean of 2 4 5 1 3?
The mean of 2, 4, 5, 1, and 3 is 3. To find the mean of a set of numbers, you first add them all up. 2+4+5+1+3= 15. Then you divide that sum by the number of numbers in the set. 15/5= 3.
How do you determine the mean of numbers?
add all of them up and divide by amount of numbers eg 1 2 3 4 5 1+2+3+4+5 / 5
What 4 numbers that have a mean of 4 and a range of 4?
1, 5, 5, and 5 5+5+5+1=16/4=4 5-1=4
How do you find the mean in math?
The mean is the same as average. You add up all the numbers in the set then divide it by how many numbers there are. for example: pretend the numbers are 4,2,7,5,2. to find the mean i add them all up. 139+2+7+5+2=155. now i divide. there are 5 numbers so 155 divided by 5 is 31. 31 is the mean.
Is the mean median and mode of the numbers 1 3 5 2 4 8 4 7 2?
1, 2, 2, 3, 4, 4, 5, 7, 8 Mean: 4 Median: 4 Mode: 2 and 4
