What three numbers have an average of 994?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 994. This means if we add these three numbers together and divide by 3, we should get 994.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 994 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 994 * 3 = x + y + z
- So, the sum of our three numbers should be: 2982
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 2982.
Solution 1:
994, 994, 994
Verification:
(994 + 994 + 994) / 3 = 2982 / 3 ≈ 994
This solution is correct!
Solution 2:
994, 994, 994
Verification:
(994 + 994 + 994) / 3 = 2982 / 3 ≈ 994
This solution is correct!
Solution 3:
2936, 27, 19
Verification:
(2936 + 27 + 19) / 3 = 2982 / 3 ≈ 994
This solution is correct!
Solution 4:
1825, 324, 833
Verification:
(1825 + 324 + 833) / 3 = 2982 / 3 ≈ 994
This solution is correct!
Solution 5:
42, 498, 2442
Verification:
(42 + 498 + 2442) / 3 = 2982 / 3 ≈ 994
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 2982 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.
