Determine the arithmetic mean between the given numbers.
1. 12 and 27
2. 2 and 48
3. 23.8 and 45.2
4. 1.44 and 2.36
Answer (2)
To find the arithmetic mean (also known as the average) between two given numbers, you add the numbers together and then divide the sum by 2. This process provides the middle value between them.
Here are the steps for each pair:
Between 12 and 27:
First, add the numbers:
12 + 27 = 39
Then, divide the sum by 2:
2 39 = 19.5
So, the arithmetic mean between 12 and 27 is 19.5.
Between 2 and 48:
First, add the numbers:
2 + 48 = 50
Then, divide the sum by 2:
2 50 = 25
So, the arithmetic mean between 2 and 48 is 25.
Between 23.8 and 45.2:
First, add the numbers:
23.8 + 45.2 = 69
Then, divide the sum by 2:
2 69 = 34.5
So, the arithmetic mean between 23.8 and 45.2 is 34.5.
Between 1.44 and 2.36:
First, add the numbers:
1.44 + 2.36 = 3.8
Then, divide the sum by 2:
2 3.8 = 1.9
So, the arithmetic mean between 1.44 and 2.36 is 1.9.
These calculations give you the arithmetic mean for each pair of numbers, which helps in understanding the central value between them.
The arithmetic mean between each pair of numbers is calculated by adding the two numbers and dividing by 2. The means are: 19.5 for 12 and 27, 25 for 2 and 48, 34.5 for 23.8 and 45.2, and 1.9 for 1.44 and 2.36. This process allows us to find the central value in each case.
