What three numbers have an average of 434?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 434. This means if we add these three numbers together and divide by 3, we should get 434.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 434 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 434 * 3 = x + y + z
- So, the sum of our three numbers should be: 1302
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 1302.
Solution 1:
434, 434, 434
Verification:
(434 + 434 + 434) / 3 = 1302 / 3 ≈ 434
This solution is correct!
Solution 2:
434, 434, 434
Verification:
(434 + 434 + 434) / 3 = 1302 / 3 ≈ 434
This solution is correct!
Solution 3:
331, 618, 353
Verification:
(331 + 618 + 353) / 3 = 1302 / 3 ≈ 434
This solution is correct!
Solution 4:
1268, 33, 1
Verification:
(1268 + 33 + 1) / 3 = 1302 / 3 ≈ 434
This solution is correct!
Solution 5:
138, 943, 221
Verification:
(138 + 943 + 221) / 3 = 1302 / 3 ≈ 434
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 1302 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.
