1. The problem appears to be a list of numbers: 20, 12, 3, 8, 12, 9. 2. Since no specific question is asked, let's analyze these numbers for common algebraic or arithmetic properties. 3. We can find the mean (average) of these numbers using the formula: $$\text{Mean} = \frac{\text{Sum of all numbers}}{\text{Number of numbers}}$$ 4. Calculate the sum: $$20 + 12 + 3 + 8 + 12 + 9 = 64$$ 5. Count the numbers: there are 6 numbers. 6. Calculate the mean: $$\frac{64}{6} = 10.67$$ (rounded to two decimal places) 7. We can also find the median, which is the middle value when numbers are sorted. 8. Sort the numbers: 3, 8, 9, 12, 12, 20. 9. Since there are an even number of values, median is the average of the 3rd and 4th numbers: $$\frac{9 + 12}{2} = 10.5$$ 10. The mode is the number that appears most frequently, which is 12. Final answers: - Mean: 10.67 - Median: 10.5 - Mode: 12
