To find the sum of a set of numbers, you can use this formula: ∑ = (x)(x+1)/2 That is..... The sum = (The number of samples)(The number of samples + 1)/2 Example: What is the sum of all numbers between 500 and 1000? Assuming that we do not include 500 or 1000 in our answer, we have 498 numbers to add up. Let's put that into the formula.... ∑ = (498)(498+1)/2 ∑ = (498)(499)/2 ∑ = (248,502)/2 ∑ = 124,251 The Answer is 124,251
The average of a set of numbers is defined as the sum of those numbers divided by the number of numbers. If the average is given, multiply that by number of items in the set including the missing number. Subtract the sum of given numbers from this quotient and the missing number is revealed.
It is 260.
There is no set of two consecutive even numbers that total -96. There is only a set of odds. The numbers are -49 and -47.
the mean or average of the set
To find the median with two numbers, do as you would to find the "average" or the "mean" by finding the sum between the two numbers and dividing the sum (or total) by two.
It is the mean average
to find the mean of a set of numbers you have to find the total sum of the data divided by the number of addends in the data.
To find the average of a set of numbers, you add all the numbers together. Then you divide this sum by the size of the set - for instance, if you have 10 numbers, you divide the sum by 10.
The average of a set of numbers is the sum of the numbers in the set divided by the number of elements in the set.
It would be useful to know what the deviations were from.
The sum of the set of numbers divided by the amount of numbers.
The average of a set of numbers is defined as the sum of those numbers divided by the number of numbers. If the average is given, multiply that by number of items in the set including the missing number. Subtract the sum of given numbers from this quotient and the missing number is revealed.
The sum of a set of numbers divided by the number of addends is the mean average of that set.
First, you add all of the numbers in the set together. Then, you divde the sum by however many numbers there are in the set of data. Your quotient is the average/mean.
You get the mean average of the numbers in the set.
The mean is 7.375. You can find this by adding all the numbers in the set then dividing the sum by the amount of numbers in the set.
Finding the mean (average) of a single number is pointless. It will always be the number. To find the mean of a set of numbers, total the numbers in the set and divide that total by the number of members of the set.
