Math Problem Statement
6 numbers from 0 to 9 that have a median of 4, a mean of 4 and a mode of 3
Solution
To determine 6 numbers between 0 and 9 that meet the following criteria:
- Median of 4: The middle two numbers (when sorted) must average to 4, as there are 6 numbers.
- Mean of 4: The sum of the numbers must be .
- Mode of 3: The number 3 must appear more often than any other number.
Step-by-step solution:
1. Median of 4
For the median to be 4, the middle two numbers (when sorted) must be either:
- Both 4 (, or
- Numbers that average to 4, such as 3 and 5.
2. Mode of 3
To ensure the mode is 3, 3 must appear at least twice, preferably more.
3. Mean of 4
The total of the 6 numbers must be .
Possible solution:
Consider:
- Median: The two middle numbers are 4 and 4. Their average is 4.
- Mean: .
- Mode: The number 3 appears most often (twice).
Thus, satisfies all the criteria.
