No. But there can be more than one data point which has the same value as the mean for the set of numbers. Or there can be none that take the mean value.
Yes.
A pair of numbers can have more than one factor because the numbers keep going on.
There are more than one: 25, 36 and 49.
A set is just a way of describing numbers, and numbers can be described in more than one way. If set A is (for example) all positive prime numbers, and set B is all numbers between 0 and 10, then there are some numbers (2, 3, 5, and 7) that could belong to both sets.
38 and 12
There is one arithmetic mean and one geometric mean to a set of numbers.
For any set of numbers, there can only be one mean, so it is not an issue that can arise. If you are working with more than one set of figures, then you can have more than one mean. What you do then is really dependent on what it is that you want to do with them, so there is no single answer to the question.
In order to find the mean, you need to provide more than one number. To find the mean of something, add up all the numbers, then divide by how many numbers there are.
All the counting numbers, 1,2,3 are more than one third.
Composite numbers are integers or whole numbers that contain more than two factors in them. Prime numbers are also integers but only have two factors which are themselves and one.
Composite numbers are said as non-prime numbers. They have more than 2 factors, one of them is non prime.
Yes.
Yes.
yes it can
prime numbers are numbers that can only be divided by one and itself. Composite numbers can be divided by more than one and itself.
No; two numbers can have only 1 GCF.
There is more than one type of average (of a collection of numbers) The MEAN is all the numbers added up, divided by the amount of numbers there are. This is the most common average.
