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:
522, 482, 682
Verification:
(522 + 482 + 682) / 3 = 1686 / 3 ≈ 562
This solution is correct!
Solution 4:
414, 899, 373
Verification:
(414 + 899 + 373) / 3 = 1686 / 3 ≈ 562
This solution is correct!
Solution 5:
793, 865, 28
Verification:
(793 + 865 + 28) / 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.
