What three numbers have an average of 559?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 559. This means if we add these three numbers together and divide by 3, we should get 559.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 559 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 559 * 3 = x + y + z
- So, the sum of our three numbers should be: 1677
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 1677.
Solution 1:
559, 559, 559
Verification:
(559 + 559 + 559) / 3 = 1677 / 3 ≈ 559
This solution is correct!
Solution 2:
559, 559, 559
Verification:
(559 + 559 + 559) / 3 = 1677 / 3 ≈ 559
This solution is correct!
Solution 3:
1447, 79, 151
Verification:
(1447 + 79 + 151) / 3 = 1677 / 3 ≈ 559
This solution is correct!
Solution 4:
976, 37, 664
Verification:
(976 + 37 + 664) / 3 = 1677 / 3 ≈ 559
This solution is correct!
Solution 5:
495, 694, 488
Verification:
(495 + 694 + 488) / 3 = 1677 / 3 ≈ 559
This solution is correct!
Explanation:
As you can see, there are many possible solutions. We can find more by:
- Choosing any two numbers
- Subtracting their sum from 1677 to get the third number
Remember:
- The numbers don't have to be whole numbers.
- They can even be negative (although that might not make sense in some real-world contexts).
- The order of the numbers doesn't matter for the average.
