Any set of numbers that contain them! For example, they belong to the set
{10, 11}
or {10, 11, sqrt(2), pi, -3/7},
or {10, 11, bananas, France, cold}
or all whole numbers between 3 and 53,
or counting numbers,
or integers,
or rational numbers,
or real numbers,
or complex numbers,
etc.
There are an infinite number of sets of numbers. 9,10 an 11 9,9,10,11 and 11 9,9,9,10,11,11 and 11 etc, for example, is one family of sets of numbers.
There are 4 possible answers: (7, 7, 10, 13, 13) (7, 8, 10, 12, 13) (7, 9, 10, 11, 13) (8, 8, 10, 10 14).
For 8 9 9 9 10 11 11 12: σ=1.3562
There are 11 numbers from 10 to 20 if we include 10 and 20. Of those, only 16 is a perfect square. So the probability if 1/11 or .09 repeating.
2,3,4,6,6,6,6,6,7,7,8,11
rational and prime numbers
There are an infinite number of sets of numbers. 9,10 an 11 9,9,10,11 and 11 9,9,9,10,11,11 and 11 etc, for example, is one family of sets of numbers.
The set of all odd natural numbers less than 10 is [1,3,5,7,9].
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.
The mean is a form of average. Generally speaking, the mean of a set of numbers is the result of adding all the numbers together and dividing by the number of numbers e.g. 1, 3, 5, 6, 6, 10, 11 The mean is 1 + 3 + 5 + 6 + 6 + 10 + 11 7 = 6
16
The range is 11. (14 - 3 = 11)
2
If you are including 10 and 30 there are 11 even numbers. If you are not counting 10 and 30 there are 9 even numbers between 10 and 30.
9 and 10 are but 11 is prime
No. The set of whole numbers does not include negative numbers. There are 11 integers in that range.
