What three numbers have an average of 529?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 529. This means if we add these three numbers together and divide by 3, we should get 529.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 529 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 529 * 3 = x + y + z
- So, the sum of our three numbers should be: 1587
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 1587.
Solution 1:
529, 529, 529
Verification:
(529 + 529 + 529) / 3 = 1587 / 3 ≈ 529
This solution is correct!
Solution 2:
529, 529, 529
Verification:
(529 + 529 + 529) / 3 = 1587 / 3 ≈ 529
This solution is correct!
Solution 3:
1571, 9, 7
Verification:
(1571 + 9 + 7) / 3 = 1587 / 3 ≈ 529
This solution is correct!
Solution 4:
733, 46, 808
Verification:
(733 + 46 + 808) / 3 = 1587 / 3 ≈ 529
This solution is correct!
Solution 5:
376, 803, 408
Verification:
(376 + 803 + 408) / 3 = 1587 / 3 ≈ 529
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 1587 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.
