Question 2 • VA-Mathematical Analysis
Machine engineers are designing a new ice cube machine. They notice that designs that use cubes containing higher volumes of water take longer to freeze. The data in the table show various volumes (in milliliters) and freezing times (in hours) for a sample of machine designs.
Answer
A
A graph titled Volume and Freezing Time shows Volume (milliliters) 38 to 56 on the x-axis and Freezing time (hours) 0.6 to 2.2 on the y-axis. The points show an upward trend.
B
A graph titled Freezing time (hours) 0.6 to 2.2 on the x-axis and Volume and Freezing Time shows Volume (milliliters) 38 to 56 on the y-axis. The points show an upward trend.
C
A graph titled Volume and Freezing Time shows numbers 38 to 56 on the x-axis and numbers 0.6 to 2.2 on the y-axis. The points show an upward trend.
D
A graph titled Volume and Freezing Time shows Volume (milliliters) on the x-axis and Freezing time (hours) on the y-axis. The points show an upward trend.
