Problem Analysis:
The image provided is a line plot showing the number of marks obtained by 6 students in their math exam out of a total of 100 marks. Each "x" on the line plot represents 10 marks. We need to answer five questions based on this line plot.
Line Plot Breakdown:
-
Zara: 2 "x"s → \(2 \times 10 = 20\) marks
-
Alex: 3 "x"s → \(3 \times 10 = 30\) marks
-
Gabriel: 4 "x"s → \(4 \times 10 = 40\) marks
-
Shaun: 5 "x"s → \(5 \times 10 = 50\) marks
-
Marry: 6 "x"s → \(6 \times 10 = 60\) marks
-
Ali: 10 "x"s → \(10 \times 10 = 100\) marks
Questions and Solutions:
####
1) How many marks did Zara get?
- From the line plot, Zara has 2 "x"s.
- Each "x" represents 10 marks.
- Therefore, Zara's marks = \(2 \times 10 = 20\).
Answer: 20
####
2) How many more marks did Shaun score than Alex?
- Shaun has 5 "x"s, so Shaun's marks = \(5 \times 10 = 50\).
- Alex has 3 "x"s, so Alex's marks = \(3 \times 10 = 30\).
- Difference in marks = \(50 - 30 = 20\).
Answer: 20
####
3) Who got 100 out of 100 marks?
- From the line plot, Ali has 10 "x"s.
- Each "x" represents 10 marks, so Ali's marks = \(10 \times 10 = 100\).
Answer: Ali
####
4) Name the student who got 60 marks in the exam?
- From the line plot, Marry has 6 "x"s.
- Each "x" represents 10 marks, so Marry's marks = \(6 \times 10 = 60\).
Answer: Marry
####
5) Who scored the least marks in the test?
- From the line plot:
- Zara: 20 marks
- Alex: 30 marks
- Gabriel: 40 marks
- Shaun: 50 marks
- Marry: 60 marks
- Ali: 100 marks
- The student with the least marks is Zara, with 20 marks.
