Jason polled a large sample of individuals to find the entrance exam scores from 0 to 100 of out-of-state students. Which of the following would be an appropriate choice to display the results? a. pie chart.
b. bar graph.
c. histogram.
d. dot plot.

c. histogram.

Step-by-step explanation:

In this case, the most appropiate way to show the results is to group the results in classes (for example from score 0 to 20, 21 to 40, 41 to 60, until 100) and show the relative frequency for each of the classes.

An histogram allows us to present this information graphically in the ways described before.

A pie chart is appropiate to show proportions.

A bar graph is similar but for discrete or non-numerical categories.

A dot plot is adequate por discrete classes and small samples.

step-by-step explanation:

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
