Since there are five numbers in that group, the
mean (average) of the group is 1/5 of their sum.
23/20 = 13/20
There are an infinite number of sets-of-4 that all have a mean of 12. Here are a few of them : 12, 12, 12, and 12 10, 11, 12, and 15 5, 10, 15, and 18 5, 7, 13, and 23 -12, 10, 20, and 30 1, 2, 3, and 42
13/20 = 23/20
It is: 15
4/20 + 2/13 = 92/260 or 23/65
30.666
15.4
23/20 = 13/20
13 + 23 + 12 + 7 = 55
There are an infinite number of sets-of-4 that all have a mean of 12. Here are a few of them : 12, 12, 12, and 12 10, 11, 12, and 15 5, 10, 15, and 18 5, 7, 13, and 23 -12, 10, 20, and 30 1, 2, 3, and 42
You find the mean by adding the numbers and dividing by 5 so the mean is 15.4
To find the mode or modal value requires you to put the numbers you are given in order.Look at these numbers:3, 7, 5, 13, 20, 23, 39, 23, 40, 23, 14, 12, 56, 23, 29In order these numbers are:3, 5, 7, 12, 13, 14, 20, 23, 23, 23, 23, 29, 39, 40, 56This makes it easy to see which numbers appear the most.In this case the mode or modal value is 23.
1, 2, 3, 4, 10,. 11, 12, 13, 14, 20,. 21, 22, 23, 24, 30
13/20 = 23/20
Your question has many possible answers. For example 3 + 20 is 23 But also 10 + 13 is 23 And 8 + 15 is 23
7/8 + 1/12 = 23/24=7/8 +1/12= 21/24 + 2/24= 23/24
Twice ... 1916 (23-12) and 1917 (24-13).
