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.

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.

Mean is the same as average. To get the mean of a set of numbers: First, you add up all the numbers. Second, you divide by the number of numbers in the set. Total of all the numbers/Number of numbers in the set

The sum of the set of numbers divided by the amount of numbers.

You are finding the mean of the set of numbers.

You get the mean average of the numbers in the set.

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, 82Here's another one:79, 81, -600, 400, 440.The mean doesn't tell us anything about what the individual numbers must be.

Add up the numbers, and then divide by the number of numbers in the set. This will give you the mean.

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.

mean means the average or all the numbers in the set added together and then divided by the number of numbers in the set of numbers.

In every day language ; mean' can be said as 'Average'.

The mean is the is the total of the numbers and then dividing by how many numbers.

If you mean larger by "the set of whole numbers strictly contains the set of natural numbers", then yes, but if you mean "the set of whole numbers has a larger cardinality (size) than the set of natural numbers", then no, they have the same size.

You get the mean average of the numbers in the set.
