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
The mean is the average. To get an average age of three, 3 of her pets would have to 4 years old and the other 3 would be 2 years old. In ten years she would have 3 pets that are 14 and three that are 12, therefore the mean age of them would be= [(14*3)+ (12*3)]/6= 13 So in following the same concept, 20 years the mean age of her pets would be 23.
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
