What three numbers have an average of 564?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 564. This means if we add these three numbers together and divide by 3, we should get 564.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 564 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 564 * 3 = x + y + z
- So, the sum of our three numbers should be: 1692
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 1692.
Solution 1:
564, 564, 564
Verification:
(564 + 564 + 564) / 3 = 1692 / 3 ≈ 564
This solution is correct!
Solution 2:
564, 564, 564
Verification:
(564 + 564 + 564) / 3 = 1692 / 3 ≈ 564
This solution is correct!
Solution 3:
1436, 127, 129
Verification:
(1436 + 127 + 129) / 3 = 1692 / 3 ≈ 564
This solution is correct!
Solution 4:
1082, 134, 476
Verification:
(1082 + 134 + 476) / 3 = 1692 / 3 ≈ 564
This solution is correct!
Solution 5:
187, 1307, 198
Verification:
(187 + 1307 + 198) / 3 = 1692 / 3 ≈ 564
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 1692 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.
