How do you average two negative numbers?
The same as two positive numbers. -4 . & -10 Mean = (-4 + -10)/2 Mean = -14/2 Mean = -7 NB In mathemtical terms, the word, 'average' is NOT used. It is the MEAN.,
4 numbers mean 10 median 10 but none of the numbers are ten?
To achieve a mean of 10 with four numbers, their total must be 40. If the median is also 10, then when the numbers are arranged in order, the average of the two middle numbers must equal 10. This can be done with combinations of numbers such as 5, 5, 15, and 15, which satisfy both conditions: their mean is 10, their median is 10, and none of the numbers are 10.
What does the word mean mean in mathmatical terms?
it means the average. add up all of the numbers and divide by the number of numbers you added. for example, 10+ 10+10=30 the mean is 30 divided by 3 = 10 the average! A nasty average?
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.
What is a mean of 5 10 15?
It means you are counting in increments of 5. 5+5=10, 10+5=15. If by the word "mean", you are talking about the average, then the mean is 10. To determine the average of any group of numbers, add the numbers and divide the total by the number of numbers added - (does this makes sense?) Example: 5 + 10 + 15 = 30. Divide 30 by 3 (you added 3 numbers together to get the total) and the average is 10. Hope this helps.
What is the average of two number is 10?
Assuming mean average: average = sum/number_of_items → 10 = sum/2 → sum = 10 x 2 = 20 So any two numbers with a sum of 10 have a mean average of 10, eg {5, 15}, {1, 19}, {0, 20}, {-5, 25}, etc. With the median average, for two numbers it is exactly the same as the mean average, so any pair of numbers that sum to 20 will do. With the mode average, only the case of the pair of numbers {10, 10} will suffice.

The average of two numbers is 10 What is the sum of the two numbers?
Avreage = Sum/number of values So 10 = sum/2 Multiply both sides by 2: 20 = sum

What is the mean of a group of numbers?
The average. The mean is the same as the average. For example: the mean of 4,6,10,20 is 10. 4+6+10+20=40/4=10
What is the mean average of these numbers 18 12 10 10 25?
Well, isn't that just a happy little group of numbers we have there? To find the mean average, you simply add up all the numbers and then divide by how many there are. So, for these numbers, you would add 18 + 12 + 10 + 10 + 25, which equals 75. Then, you divide 75 by 5 (since there are 5 numbers), giving you a mean average of 15. Happy calculating!
What is two numbers whose geometric mean is 10?
Multiply 10 by any number except zero, then divide 10 by the same number. The geometric mean of those two numbers will be 10.

What happens when you have two middle value numbers for a median?
A paradox occurs in the space-time continuum and the universe ceases to exist ;) But seriously, what you probably REALLY mean is how do you find the median of a list of numbers with an even number of numbers. When you have an even number of numbers, you take the average of the two middle numbers. So for example: 1, 6, 8, 10, 15, 20 The two middle numbers are 8 and 10. The average of 8 and 10 is 9, so the median of the above example is 9.
What is the mean of the following numbers 12 14 25 10 25 15 11?
The mean (average) of those numbers is 16.
