What three numbers have an average of 562?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 562. This means if we add these three numbers together and divide by 3, we should get 562.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 562 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 562 * 3 = x + y + z
- So, the sum of our three numbers should be: 1686
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 1686.
Solution 1:
562, 562, 562
Verification:
(562 + 562 + 562) / 3 = 1686 / 3 ≈ 562
This solution is correct!
Solution 2:
562, 562, 562
Verification:
(562 + 562 + 562) / 3 = 1686 / 3 ≈ 562
This solution is correct!
Solution 3:
516, 67, 1103
Verification:
(516 + 67 + 1103) / 3 = 1686 / 3 ≈ 562
This solution is correct!
Solution 4:
221, 573, 892
Verification:
(221 + 573 + 892) / 3 = 1686 / 3 ≈ 562
This solution is correct!
Solution 5:
560, 848, 278
Verification:
(560 + 848 + 278) / 3 = 1686 / 3 ≈ 562
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 1686 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.
