What three numbers have an average of 165?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 165. This means if we add these three numbers together and divide by 3, we should get 165.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 165 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 165 * 3 = x + y + z
- So, the sum of our three numbers should be: 495
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 495.
Solution 1:
165, 165, 165
Verification:
(165 + 165 + 165) / 3 = 495 / 3 ≈ 165
This solution is correct!
Solution 2:
165, 165, 165
Verification:
(165 + 165 + 165) / 3 = 495 / 3 ≈ 165
This solution is correct!
Solution 3:
97, 161, 237
Verification:
(97 + 161 + 237) / 3 = 495 / 3 ≈ 165
This solution is correct!
Solution 4:
324, 29, 142
Verification:
(324 + 29 + 142) / 3 = 495 / 3 ≈ 165
This solution is correct!
Solution 5:
358, 87, 50
Verification:
(358 + 87 + 50) / 3 = 495 / 3 ≈ 165
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 495 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.
