drag each example to the correct location on the chart. identify each example as a discrete random variable or a continuous random variable. the average annual increase in fuel price a cars speed at different times the number of cars passing through a toll both in an hour the number of phone calls made in a day the salaries of employees in an office discrete random variable continuous random variable

drag each example to the correct location on the chart. identify each example as a discrete random variable or a continuous random variable. the average annual increase in fuel price a cars speed at different times the number of cars passing through a toll both in an hour the number of phone calls made in a day the salaries of employees in an office discrete random variable continuous random variable

Answer

Explanation:

Step1: Recall definitions

Discrete random variables take on countable values. Continuous random variables can take on any value in an interval.

Step2: Analyze "the average annual increase in fuel price"

It can take any value in an interval, so it's continuous.

Step3: Analyze "a car's speed at different times"

Speed can take any value in an interval, so it's continuous.

Step4: Analyze "the number of cars passing through a toll booth in an hour"

The number of cars is countable, so it's discrete.

Step5: Analyze "the number of phone calls made in a day"

The number of phone - calls is countable, so it's discrete.

Step6: Analyze "the salaries of employees in an office"

Salaries can take any value in a range (e.g., $3000.50, $3000.75 etc.), so it's continuous.

Answer:

Discrete Random Variable: the number of cars passing through a toll booth in an hour, the number of phone calls made in a day Continuous Random Variable: the average annual increase in fuel price, a car's speed at different times, the salaries of employees in an office
