What three numbers have an average of 995?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 995. This means if we add these three numbers together and divide by 3, we should get 995.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 995 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 995 * 3 = x + y + z
- So, the sum of our three numbers should be: 2985
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 2985.
Solution 1:
995, 995, 995
Verification:
(995 + 995 + 995) / 3 = 2985 / 3 ≈ 995
This solution is correct!
Solution 2:
995, 995, 995
Verification:
(995 + 995 + 995) / 3 = 2985 / 3 ≈ 995
This solution is correct!
Solution 3:
2690, 292, 3
Verification:
(2690 + 292 + 3) / 3 = 2985 / 3 ≈ 995
This solution is correct!
Solution 4:
264, 1042, 1679
Verification:
(264 + 1042 + 1679) / 3 = 2985 / 3 ≈ 995
This solution is correct!
Solution 5:
1463, 87, 1435
Verification:
(1463 + 87 + 1435) / 3 = 2985 / 3 ≈ 995
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 2985 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.
