A group of students measured the average monthly temperature of 1000 cities around the world and plotted the cumulative frequency graph shown below. A cumulative frequency graph. The label for the x-axis reads 'Average monthly temperature (in degrees Celsius).' The label for the y-axis reads 'Cumulative Frequency (number of cities).' The coordinates that make up the shape of the line are as follows: (0,0), (10,50), (20,50), (30,400), (40,700), (50,950), (60,1000), (70,1000). Which of these conclusions is correct about the cities whose temperatures were measured by the students? About 300 cities have an average monthly temperature of 60°C. About 300 cities have an average monthly temperature of 20°C. Almost 50% of the cities have an average monthly temperature less than or equal to 35°C. Almost 50% of the cities have an average monthly temperature less than or equal to 20°C.

Because air contracts as it cools, the air pressure inside a freezer is typically lower than on the outside. why do ice cubes inside a freezer tend to shrink over time? a. the ice dissolves oxygen from the air, forming a denser crystalline matrix. b. the ice reacts chemically with carbon dioxide in the air, forming gaseous carbon compounds. c. the ice melts, and then the liquid freezes as ice crystals on the bottom of the freezer. d. the ice sublimes, and then the water vapor deposits as ice crystals on the sides of the freezer.
