What three numbers have an average of 823?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 823. This means if we add these three numbers together and divide by 3, we should get 823.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 823 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 823 * 3 = x + y + z
- So, the sum of our three numbers should be: 2469
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 2469.
Solution 1:
823, 823, 823
Verification:
(823 + 823 + 823) / 3 = 2469 / 3 ≈ 823
This solution is correct!
Solution 2:
823, 823, 823
Verification:
(823 + 823 + 823) / 3 = 2469 / 3 ≈ 823
This solution is correct!
Solution 3:
834, 500, 1135
Verification:
(834 + 500 + 1135) / 3 = 2469 / 3 ≈ 823
This solution is correct!
Solution 4:
778, 1537, 154
Verification:
(778 + 1537 + 154) / 3 = 2469 / 3 ≈ 823
This solution is correct!
Solution 5:
1222, 414, 833
Verification:
(1222 + 414 + 833) / 3 = 2469 / 3 ≈ 823
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 2469 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.
