What three numbers have an average of 970?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 970. This means if we add these three numbers together and divide by 3, we should get 970.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 970 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 970 * 3 = x + y + z
- So, the sum of our three numbers should be: 2910
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 2910.
Solution 1:
970, 970, 970
Verification:
(970 + 970 + 970) / 3 = 2910 / 3 ≈ 970
This solution is correct!
Solution 2:
970, 970, 970
Verification:
(970 + 970 + 970) / 3 = 2910 / 3 ≈ 970
This solution is correct!
Solution 3:
1190, 1498, 222
Verification:
(1190 + 1498 + 222) / 3 = 2910 / 3 ≈ 970
This solution is correct!
Solution 4:
2247, 8, 655
Verification:
(2247 + 8 + 655) / 3 = 2910 / 3 ≈ 970
This solution is correct!
Solution 5:
939, 1188, 783
Verification:
(939 + 1188 + 783) / 3 = 2910 / 3 ≈ 970
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 2910 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.
