A bar graph shows the average rainfall in inches for four months in a given year: January (5 inches), February (3 inches), March (7 inches), and April (4 inches). What is the total rainfall for the first four months?

A scatter plot shows a positive correlation between temperature and plant growth. If the temperature increases by 10 degrees, how much does plant growth increase if the correlation coefficient is 0.9?

A graph shows the volume of a gas versus its pressure at a constant temperature, indicating an inverse relationship. If the pressure is doubled, what happens to the volume?

A bar graph shows the frequency of four different bacteria types in a lab. If the graph shows 12 Type A, 8 Type B, 5 Type C, and 15 Type D bacteria, what percentage of the total bacteria are Type B?

A line graph depicts the number of customers in a store during business hours. The number starts at 20 customers, peaks at 80 customers, and then decreases to 40 customers. If this pattern occurs within a 12-hour period, what is the average change in customer count per hour over the first 6 hours?

A scatter plot shows a positive correlation between study hours and test scores for a class of students. If a student increases their study time by 5 hours and sees an average increase of 10 points in their test score, what can be inferred about the relationship between study time and test scores?

A scatter plot shows a negative correlation between temperature and fish population in a lake. If the temperature increases by 10 degrees, how much does the fish population decrease if the correlation coefficient is -0.75?

A table shows the data for the population of a certain species of birds in five different regions: Region A (50 birds), Region B (40 birds), Region C (60 birds), Region D (55 birds), and Region E (45 birds). What is the median population for these regions?

A line graph shows the speed of a train over time. It starts at 0 km/h, accelerates to 90 km/h within 15 minutes, and then decelerates to 60 km/h over the next 10 minutes. What is the average acceleration during the first 15 minutes?

A table lists the pH values for five different substances: Substance A (7.5), Substance B (8.0), Substance C (6.5), Substance D (9.0), and Substance E (7.0). What is the mode pH value among these substances?

A bar graph displays the frequency of four different species of insects in a forest. If the graph shows 50 Species A, 30 Species B, 40 Species C, and 60 Species D, what percentage of the total is Species C?

A scatter plot shows a linear relationship between hours of exercise and weight loss. If a person exercises for 10 hours and loses 5 kg, how much weight is expected to be lost by a person who exercises for 30 hours?

A graph shows the growth of a tree over a 10-year period. The tree's height begins at 2 meters, grows to 8 meters over 5 years, and reaches 10 meters by the end of the 10-year period. What is the average rate of growth during the first 5 years?

A bar graph displays the number of cars sold in four months: January (50 cars), February (40 cars), March (60 cars), and April (70 cars). What is the average number of cars sold per month?

A table shows the production of different types of fruits in a farm over a year: 200 kg of apples, 150 kg of oranges, 100 kg of bananas, and 250 kg of grapes. What percentage of the total production is made up of apples?

A table shows the height of five different trees in a park: Tree A (10 meters), Tree B (15 meters), Tree C (20 meters), Tree D (12 meters), and Tree E (18 meters). What is the median height of these trees?

A scatter plot shows a relationship between exercise duration and energy levels. If a person exercises for 30 minutes and their energy level increases by 15 units, how much is expected to increase if they exercise for 60 minutes?

A bar graph shows the number of books read by four different students over a year: Alice (20 books), Bob (30 books), Carol (40 books), and David (50 books). What is the average number of books read per student?

A scatter plot shows a negative correlation between temperature and fish population in a lake. If the temperature increases by 10 degrees, how much does the fish population decrease if the correlation coefficient is -0.75?

A bar graph displays the number of cars sold in four months: January (50 cars), February (40 cars), March (60 cars), and April (70 cars). What is the average number of cars sold per month?
