There are an infinite list of different sets of 5 that do that.
If their mean is 80, then the only thing you know about them is that they add up to 400.
Here's one set:
78, 79, 80, 81, 82
Here's another one:
79, 81, -600, 400, 440.
The mean doesn't tell us anything about what the individual numbers must be.

What is the range of 80 90 90 95 100?
The range of a set of numbers is the difference between the highest and lowest values. In this case, the highest value is 100 and the lowest value is 80. Therefore, the range of the numbers 80, 90, 90, 95, and 100 is 20.
If one three-digit number is chosen at random from all those that can be made from the above set of digits find the probability that one is not multiple of 5?
An interesting question. The answer is 80%. A number must end in 0 or 5 to be dividable by 5. From 100 to 109 (10 numbers in total), there will be 2 numbers that are dividable by 5. If I then consider the entire set from 100 to 999 is 900 numbers, you have 90 sets of 10 numbers, each set with 2 dividable number, or 180/900 = 2/10 =20%. If 20% are dividable, 80% aren't. Suppose I extended the question, and say my set is all whole positive numbers and zero with n digits or less, where I pick n randomly from 1 to a million. If from this set, a number is picked randomly, what is the chance that it is dividable by 5. Answer: 20%.
What is the mean for 80 85 76 70 87 80 90 80 90?
82.
What two numbers when multiplied give you -80 and when added give you -11?
-91
What fraction of 20 is 2.25?
Multiply both numbers by 4 to get rid of the .25 and you have the equivalent question, "what fraction of 80 is 9?" The answer is 9/80
What set of numbers has a mean of 80?
There are an infinite number of sets with mean 80. Here are some: {80, 80, 80}, {80, 80, 80, 80, 80, 80} {79, 80, 81}, {79, 79, 80, 81, 81}, {79, 79, 80, 82} (1, 80, 159}, {-40, 200} To produce a set of n numbers with mean 80, start with any set of n-1 numbers. Suppose their sum is S. Then add the number 80*n-S to the set. You will now have n numbers whose sum is S+80*n-S = 80*n So the mean of this set is 80.
What group 0 3 6 27 80 part of?
I am assuming the you do not mean "group", which has a very specific mathematical meaning, but "set". The numbers belong to any set that will contain them! For example, {0, 3, 6, 27, 80}; {0, 3, pi, 6, sqrt(105), 27, 80}; N, the set of natural numbers, Z, the set of integers, Q, the set of rational numbers, R, the set of real numbers, C, the set of complex numbers, the set of integers between -30 and +130, the set of rational numbers between -97/4 and 641/5, the set of positive square roots of all non-negative numbers less than 9000.
What does mean as in 2500 personnel?
Mean is a mathematical average. To find the mean of a given set of numbers, add the numbers given together, and divide by the number of items to find the mean. Example 80 + 90 +90 = 260; the mean is 260/3 = 86.333.
What prime numbers can you add to make 80?
They can be: 73+7 = 80
What number are products of 80?
They are elements of the infinite set of numbers of the form 80*k, where k is an integer.
What is the GCM of 64 and 80?
The GCM of any set of numbers is infinite.
What is the median of 100 80 80 80 95 80 95 100?
The median for this set of numbers is 87.5.The median of a set of numbers is the number that falls in the middle of all the numbers when they have been arranged in ranking order.To make this easier one needs to arrange the set of numbers from smallest to largest (rank-order)80 80 80 80 95 95 100 100.Since this group of numbers has an even number of sets we have to take the two middle sets of numbers (80 and 95) and add them together and then divide by two (80+95)/2= 87.5. This gives us the median for this set of numbers of 87.5.As many might already know to find the median for an old set of numbers, one would arrange (rank-order) the set of numbers from the smallest to largest. Next, you would locate the position of the middle score; this number is the median. There is a small formula one can use if your working with a "large" set of numbers for find out exactly where the middle position is at (n+1)/2 (note: this formula works for an even set of numbers as well but you will get a decimal point number, which will fall in between the two sets of numbers that need to be added together). The letter "n" represent the total set of numbers that we are currently looking at. So for example, if we if we were to take80 80 80 80 95 95 100 (notice I left out the other 100 from the original set of numbers in the question and I already arranged them in ranking order) now we are only working with seven sets of numbers instead of eight.Now to figure out the median for these sets of numbers we would take (n+1)/2 and plug in the number 7 for (n). (7+1)/2= 8/2=4. The number 4 now tells us exactly what position in the group of numbers we will find the median in; the 4th number in line from the left. In the 4th position we find the number 80; so for my example the median would be 80.Reference: Discovering Statistics by Andy Fields
What is the standard deviation of this set of numbers 45 87 61 73 55 78 69 80?
For this set of numbers, 45 87 61 73 55 78 69 80: σ=14.0204
Can you make 80 with the numbers 2 and 3 and 4 and 5?
80= 5x5x3+5
What 2 numbers make a difference of 2 and a product of 80?
The numbers are 10 and 8
What is the mean of 60 72 80 80 and 98?
Well, let's take a moment to appreciate these numbers, each one unique and special in its own way. To find the mean, we add them all together and then divide by how many numbers there are. So, by adding 60 + 72 + 80 + 80 + 98 and dividing by 5, we find that the mean is 78.
Math term mean?
mean is the average for example. if u have the numbers 26 14 32 and 8 you add the numbers together and you get 80. then you divide 80 by 4 because there are 4 numbers in the group. so your answer would be 20.
