Answer: discrete.

Step-by-step explanation:

Discrete variable

It is a variable whose value is evaluated by counting.

Example: Number of books published in a month.

Continuous variable

It is a variable whose value is evaluated by measuring ( not countable).

Example: Distance: 1.52 m

Since the number of dental visits a randomly chosen person had for the past 5 years is a countable.

here, Variable: Let X =number of dental visits a randomly chosen person had for the past 5 years

So, the random variable described is discrete.

Solnce55 [7]

Answer:

The speed of the Zach travelling is 8 miles per hour.

The speed of the Warren travelling is 15 miles per hour.

Step-by-step explanation:

Given : Zach and Warren both leave the coffee shop at the same time, but in opposite directions. If Warren travels 7 mph faster than Zach and after 7 hours they are 161 miles apart.

To find : How fast is each traveling?

Solution :

Let the speed of Zach is x mile per hour.

If Warren travels 7 mph faster than Zach

The speed of the Warren is x+7 miles per hour.

Zach and Warren both leave the coffee shop at the same time, but in opposite directions.

The distance covered is 161 miles in 7 hours.

We know, $\text{Distnace}=\text{Speed}\times \text{Time}$
