What three numbers have an average of 583?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 583. This means if we add these three numbers together and divide by 3, we should get 583.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 583 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 583 * 3 = x + y + z
- So, the sum of our three numbers should be: 1749
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 1749.
Solution 1:
583, 583, 583
Verification:
(583 + 583 + 583) / 3 = 1749 / 3 ≈ 583
This solution is correct!
Solution 2:
583, 583, 583
Verification:
(583 + 583 + 583) / 3 = 1749 / 3 ≈ 583
This solution is correct!
Solution 3:
400, 765, 584
Verification:
(400 + 765 + 584) / 3 = 1749 / 3 ≈ 583
This solution is correct!
Solution 4:
1700, 21, 28
Verification:
(1700 + 21 + 28) / 3 = 1749 / 3 ≈ 583
This solution is correct!
Solution 5:
90, 121, 1538
Verification:
(90 + 121 + 1538) / 3 = 1749 / 3 ≈ 583
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 1749 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.
