23*5 = 115 So pick any four numbers: integers, fractions, irrational numbers, whatever. Add them together to give a sum S. Let the 5th number be 115 - S Then: sum of all five numbers = (sum of the first four numbers) + (the fifth number) = S + (115 - S) = 115 And the count of numbers = 5 So mean = Sum/Count = 115/5 = 23
Since there are five numbers in that group, the mean (average) of the group is 1/5 of their sum.
if you mean what three prime numbers add up to a prime number then the answer is : 5 + 7 + 11 = 23

22.2. To calculate the mean, total the numbers, and then divide by the number of figures added. So, the total is 111. Divide 111 by 5 = 22.2
1,19,23,27,30 ( divided by ) 5= 20
he mean is the average of the numbers: a calculated "central" value of a set of numbers.It is easy to calculate: Just add up all the numbers, then divide by how many numbers there are.Example: what is the mean of 2, 7 and 9?Add the numbers: 2 + 7 + 9 = 18Divide by how many numbers (i.e. we added 3 numbers): 18 ÷ 3 = 6So the Mean is 6The Median is the "middle number"To find the Median, place the numbers you are given in value order and find the middle numberLook at these numbers:3, 13, 7, 5, 21, 23, 39, 23, 40, 23, 14, 12, 56, 23, 29If we put those numbers in order we have:3, 5, 7, 12, 13, 14, 21, 23, 23, 23, 23, 29, 39, 40, 56There are fifteen numbers. Our middle number will be the eighth number:3, 5, 7, 12, 13, 14, 21, 23, 23, 23, 23, 29, 39, 40, 56The median value of this set of numbers is 23.
Since 23 and 5 are prime numbers they can only be multiplied by its self, which is 1*23 and 1*5.
It is only 1 because 23 and 5 are prime numbers
23*5 = 115 So pick any four numbers: integers, fractions, irrational numbers, whatever. Add them together to give a sum S. Let the 5th number be 115 - S Then: sum of all five numbers = (sum of the first four numbers) + (the fifth number) = S + (115 - S) = 115 And the count of numbers = 5 So mean = Sum/Count = 115/5 = 23
You find the mean by adding the numbers and dividing by 5 so the mean is 15.4
15, 16, 21, 23, 25
Many combinations of number have a mean of 24. For example, 22, 23, 24, 25, and 26 have a mean of 24. To find a mean, add the numbers and divide by the count of the numbers (the number of observations): (22 + 23 + 24 + 25 + 26) ÷ 5 = 24 ...but so does this: (20 + 22 + 24 + 26 + 28) ÷ 5 = 24 ...and this: (-96 + -4 + 30 + 72 + 118) ÷ 5 = 24 ...and so on...
Mean is a fancy word for "Average". To calculate an average of a set of numbers you must add together the set of numbers and divide by the amount of numbers in the set. Let's solve your problem.4, 12, 23, 11, 5. Remember the first step is to add all the numbers together.4 + 12 + 23 + 11 + 5 = 55.Now we need to do step two - which is to divide by the amount of numbers in the set. In this case we added together 5 numbers.55/5 = 11.So the Average of {4,12,23,11,5} = 11.
Since there are five numbers in that group, the mean (average) of the group is 1/5 of their sum.
The two numbers are 9 and 23. 23-9 = 14 23-(2*9) = 5
the mean of four numbers is 25 and three of the numbers are 17 23 and 25 what is the fourth number?
