How do you find 2 mystery numbers with a mean of 5. 2 5 4 3 6 1?

If their mean is 5, then they must add up to 10.
From your list, 6 and 4 will do it.
Funny how 5 is right in the middle between those two.

How do you find the middle of 2 numbers?
What you are trying to find is the average or mean. You find this by adding all the numbers in a set together and divide by the amount of numbers you added. Example: 1, 1, 2, 2, 3, 3. Find the average (mean). Add all the numbers in the set together: 1 + 1 + 2 + 2 + 3 + 3 = 12 Divide by the amount of numbers you added: You added together 6 numbers: 12 ÷ 6 = 2. Mean of {1, 1, 2, 2, 3, 3} = 2.
How do you find the mean of first n natural numbers?
The sum of the first n natural numbers is n*(n+1)/2 There are n numbers so their mean = (n+1)/2
How many operations ( plus and and divide) to find the average of 10 numbers?
To find the mean average of 10 numbers requires the 10 number to be added together which will take 9 additions and then divide by the number of numbers which will take 1 division → 9 additions followed by 1 division, a total of 10 operations are nominally needed to find the mean average of 10 numbers.
Is zero a value in a set of numbers when trying to find the mean?
Yes. for example, the mean between 0 and 1 is 0,5
What is the maean?
To find the mean of two or more numbers you add all the numbers together and divide by how ever many numbers there are.Example:find the mean of the following numbers: 25, 10, 13, & 4step 1: add the numbers together 25+10+13+4=52step 2: divide the answer by 4 because you were told to find the mean of 4 numbers 52/4=13step 3: the answer is 13
How do you find a mean?
To find the mean of numbers, add all of the numbers together and then divide them by the number of numbers there are. For example if I want to find the mean of 1, 2, and 3. 1+2+3= 6 and there are 3 numbers that I am using to find the mean (1, 2, and 3). So I divide 6 by 3 and get 2 which is the mean.

What is the mean in math terms?
Mean refers to the average of a group of numbers. To find the mean, you add the numbers together and divide by the amount of numbers in the group. For instance, find the mean of 1, 2, 3 Add the numbers together. 1+2+3=6 3 numbers were in the original set of numbers so divide by 3 6/3=2 The mean is 2.
How do you find mean in maths?
In order to find the mean Mean= Sum of all the numbers/Number of terms For example= To find the mean of 1, 2, 3, 67, 10,5,7 Mean= 1+2+3+67+10+5+7/7 Mean= 95/7 Mean=13.57 Hence, 13.57 is the mean of the given numbers.
What is the GCF of the 85?
You need at least two numbers to find a GCF.
What 4 numbers have a mean of 80?
to find mean of four numbers, you would take the four numbers and add them. Then you would divide them by four. Now, if you want a mean of 80, just reverse the process. take the mean you want and multiply by four. Then just find four numbers that add up to the number you just got. For example if you wanted 3 numbers that have a mean of 110, you would take 110 and multiply it by 3 to get 330. Then you would find three numbers that add to 330 to get your answer. So the answer to my sample could be the numbers 1, 1, and 328 because they add to 330. A possible answer to your question would be 1, 1, 1, and 317 because if you add them up and divide by four, you would have 317+1+1+1=320. Then 320/4=80. So a possible answer could be 317, 1, 1, and 1.

How do you find the mean of positive and negative numbers?
Add up all the numbers and then divide by how many numbers there are... *Example* -8, -1, 9, 16 -8 + -1= -9+9= 0+ 16=16 16 divided by four(there are four numbers) THe mean is 4!
What is the mean of 7 2 3 2 1?
To find the mean, you add all of the numbers and divide by how many numbers you added together. 7+2+3+2+1=15. 15/5=3. The mean is 3.
