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.

If i had more info, id have a better answer. But based of luck and guessing, i am going to go with c) almost 50% of the cities have an average monthly temperature less than or equal to 35 degrees C.

The correct answer is "Almost 50% of the cities have an average monthly temperature less than or equal to 35°C".

Explanation:

The missing information of this question is as follows:

"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), (50, 10), (50, 20), (400, 30), (700, 40), (950, 50), (1000, 60), (1000, 70)".

As it can be noted by looking to the coordinate of the graph "(400, 30)", the number 400 represents the cumulative number of cities that have a temperature of at least 30 °C. Since the total number of cities is 1000, 400 cities is almost 50% of the total cities and the temperature of 30 °C less than 35°C.
