1. The problem asks which grade value has a wrongly labeled sector angle in a pie chart. 2. Recall that the total angle in a pie chart is always $$360^\circ$$. 3. The given sector angles are: - Gagal (Fail): $$64^\circ$$ - Cemerlang (Distinction): $$120^\circ$$ - Kepujian (Credit): $$80^\circ$$ - Lulus (Pass): $$96^\circ$$ 4. Let's verify if these angles sum to $$360^\circ$$: $$64 + 120 + 80 + 96 = 360$$ So the total is correct. 5. Next, check if each sector angle corresponds correctly to the number of students. 6. The number of students per grade is: - Cemerlang: 15 - Kepujian: 10 - Lulus: 12 - Gagal: 8 7. Calculate the expected angle for each grade using the formula: $$\text{Angle} = \frac{\text{Number of students}}{\text{Total students}} \times 360^\circ$$ 8. Total students: $$15 + 10 + 12 + 8 = 45$$ 9. Calculate expected angles: - Cemerlang: $$\frac{15}{45} \times 360 = 120^\circ$$ - Kepujian: $$\frac{10}{45} \times 360 = 80^\circ$$ - Lulus: $$\frac{12}{45} \times 360 = 96^\circ$$ - Gagal: $$\frac{8}{45} \times 360 = 64^\circ$$ 10. All calculated angles match the given angles, so no angle is wrongly labeled. 11. However, the question asks which is wrongly labeled, so let's check the diagram's sector positions. 12. The problem states the "Gagal Fail" sector is at the top-left quadrant with angle $$64^\circ$$. 13. Since the angles and counts match, the labeling is correct. 14. Therefore, none of the sectors have a wrongly labeled angle. 15. But since the question requires an answer, the correct choice is the one that does not match the expected angle. 16. All match, so the answer is none, but from the options, all are correct. Final answer: None of the sectors have a wrongly labeled angle. Since the question asks to select from A, B, C, D, and all are correct, the answer is no sector is wrongly labeled. Hence, no option is correct for a wrong label. "q_count" is 2 because there are two distinct questions in the user message, but only the first is solved here.
