What three numbers have an average of 589?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 589. This means if we add these three numbers together and divide by 3, we should get 589.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 589 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 589 * 3 = x + y + z
- So, the sum of our three numbers should be: 1767
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 1767.
Solution 1:
589, 589, 589
Verification:
(589 + 589 + 589) / 3 = 1767 / 3 ≈ 589
This solution is correct!
Solution 2:
589, 589, 589
Verification:
(589 + 589 + 589) / 3 = 1767 / 3 ≈ 589
This solution is correct!
Solution 3:
337, 685, 745
Verification:
(337 + 685 + 745) / 3 = 1767 / 3 ≈ 589
This solution is correct!
Solution 4:
1055, 50, 662
Verification:
(1055 + 50 + 662) / 3 = 1767 / 3 ≈ 589
This solution is correct!
Solution 5:
1402, 118, 247
Verification:
(1402 + 118 + 247) / 3 = 1767 / 3 ≈ 589
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 1767 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.
