What three numbers have an average of 284?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 284. This means if we add these three numbers together and divide by 3, we should get 284.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 284 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 284 * 3 = x + y + z
- So, the sum of our three numbers should be: 852
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 852.
Solution 1:
284, 284, 284
Verification:
(284 + 284 + 284) / 3 = 852 / 3 ≈ 284
This solution is correct!
Solution 2:
284, 284, 284
Verification:
(284 + 284 + 284) / 3 = 852 / 3 ≈ 284
This solution is correct!
Solution 3:
29, 64, 759
Verification:
(29 + 64 + 759) / 3 = 852 / 3 ≈ 284
This solution is correct!
Solution 4:
190, 28, 634
Verification:
(190 + 28 + 634) / 3 = 852 / 3 ≈ 284
This solution is correct!
Solution 5:
123, 17, 712
Verification:
(123 + 17 + 712) / 3 = 852 / 3 ≈ 284
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 852 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.
