1. **State the problem:** We need to find the total number of students based on the line plot showing the number of students scoring each quiz score from 5 to 10. 2. **Understand the data:** The line plot shows the number of students (represented by x's) for each score: - Score 5: 4 students - Score 6: 1 student - Score 7: 5 students - Score 8: 10 students - Score 9: 2 students - Score 10: 0 students 3. **Formula used:** To find the total number of students, sum the number of students for each score: $$\text{Total students} = 4 + 1 + 5 + 10 + 2 + 0$$ 4. **Calculate the total:** $$4 + 1 = 5$$ $$5 + 5 = 10$$ $$10 + 10 = 20$$ $$20 + 2 = 22$$ $$22 + 0 = 22$$ 5. **Final answer:** There are **22 students** in all who took the quiz.
