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
If you look at the numbers you can see .22 has got more numbers than .2 so it must be bigger. Also .22 = 22/100 = 11/50 .2 = 2/10 = 10/50 11/ 50 is bigger than 10/50
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.
rational and prime numbers
The square root of 121 is 11, as (11 \times 11 = 121). Any numbers that are not equal to 11 do not belong to the square root of 121. This includes all numbers such as 10, 12, -11, and any other number that is not 11.
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 numbers between 8 and 11 are 9 and 10. These numbers fall between 8 and 11 on the number line and are considered consecutive integers. In mathematical terms, they are part of the set {9, 10}.
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)
21
The numbers are -12, -11, -10 and -9.
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).
