1. The problem is to find the percentages for the "Know well" and "Know a little" segments in the pie chart given the data from the bar chart. 2. From the bar chart, the number of people in each category is: - Do not know: 5 - Know a little: 0 - Know well: 15 3. Total number of people is: $$5 + 0 + 15 = 20$$ 4. The percentage for each category is calculated by: $$\text{Percentage} = \frac{\text{Number in category}}{\text{Total number}} \times 100$$ 5. Calculate "Know well" percentage: $$\frac{15}{20} \times 100 = 75\%$$ 6. Calculate "Know a little" percentage: $$\frac{0}{20} \times 100 = 0\%$$ 7. The "Do not know" segment is given as 10%, but from the bar chart it is actually: $$\frac{5}{20} \times 100 = 25\%$$ Since the pie chart states "Do not know 10%", it seems there is a discrepancy. Assuming the pie chart is correct, the other two percentages must sum to 90%. 8. Using the pie chart's "Do not know" 10%, the remaining 90% is split between "Know well" and "Know a little". From the bar chart, "Know a little" is 0, so: - Know well = 90% - Know a little = 0% Final answer: - Know well: 90% - Know a little: 0% - Do not know: 10%
