What three numbers have an average of 973?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 973. This means if we add these three numbers together and divide by 3, we should get 973.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 973 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 973 * 3 = x + y + z
- So, the sum of our three numbers should be: 2919
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 2919.
Solution 1:
973, 973, 973
Verification:
(973 + 973 + 973) / 3 = 2919 / 3 ≈ 973
This solution is correct!
Solution 2:
973, 973, 973
Verification:
(973 + 973 + 973) / 3 = 2919 / 3 ≈ 973
This solution is correct!
Solution 3:
1588, 711, 620
Verification:
(1588 + 711 + 620) / 3 = 2919 / 3 ≈ 973
This solution is correct!
Solution 4:
1110, 46, 1763
Verification:
(1110 + 46 + 1763) / 3 = 2919 / 3 ≈ 973
This solution is correct!
Solution 5:
2892, 15, 12
Verification:
(2892 + 15 + 12) / 3 = 2919 / 3 ≈ 973
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 2919 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.
