Based on a scatter plot showing the relationship between hours.
Question
- A. 70
- B. 75
- C. 80
- D. 85
View Answer
Correct Answer ( C )
This question evaluates understanding of scatter plots and trendlines for predicting outcomes. A scatter plot shows the correlation between two variables. The trendline represents the best-fit line showing the general relationship. By locating 8 hours on the x-axis (hours studied) and finding the corresponding point on the trendline, we predict the exam score. If the trendline indicates a score of 80 for 8 hours of study, then the predicted score is 80.
A line graph depicts the temperature fluctuations over a week.
Question
- A. 30°C
- B. 35°C
- C. 40°C
- D. 45°C
View Answer
Correct Answer ( D )
This question tests the ability to interpret data from a line graph and apply simple mathematical operations to determine trends . The graph shows a daily temperature increase of 5°C from Monday to Friday . To find Friday’s temperature , we calculate the total temperature increase: 4 days * 5°C/day = 20°C , and add this to Monday’s temperature: 25°C + 20°C = 45°C . Therefore, the temperature on Friday was 45°C.
A table shows the number of students enrolled in different.
Question
- A. 30
- B. 45
- C. 60
- D. 75
View Answer
Correct Answer ( B )
This problem evaluates understanding of tables and percentage calculations : the table provides the enrollment numbers for different courses. To find the number of students enrolled in both math and science , we calculate 30% of the 150 students enrolled in math : 0.30 * 150 = 45 students , therefore 45 students enrolled in both math and science . This question requires extracting specific data from a table and using that data in a percentage calculation to answer a specific question .
A pie chart shows the distribution of a company’s budget.
Question
- A. $1,000,000
- B. $1,250,000
- C. $1,500,000
- D. $2,000,000
View Answer
Correct Answer ( B )
This question assesses understanding of pie charts and percentage calculations : a pie chart visually represents the proportions of the whole; since the marketing department received 25% of the $5 million budget , we calculate 25% of $5,000,000: (25/100) * $5,000,000 = $1,250,000 Therefore, the marketing department received $1,250,000 . This problem highlights the skill of extracting numerical information from visual data and performing basic percentage calculations within a real-world context .
A bar graph shows the sales of four products (A,.
Question
- A. 120
- B. 150
- C. 180
- D. 200
View Answer
Correct Answer ( C )
This question tests the ability to interpret data presented in a bar graph and perform calculations based on percentage increases. The problem states that product A’s Q1 sales were 20% higher than the Q4 sales of product B , which were 150 units. To find product A’s Q1 sales, we first calculate the 20% increase: 150 0.20 = 30 units. Then we add this increase to the Q4 base sales of product B: 150 30 = 180 units . Therefore, product A’s sales in Q1
