A teacher records the number of students present in her 1st period class each day. This count is a ___________ random variable.

blagie [28]

This count is a discrete random variable (option A).

<h3>What is a discrete random variable?</h3>

A discrete random variable is a variable that contains integers that can only be a limited number of possible values. A discrete random variable is can contain only a finite set of numbers .

An example of discrete random variable is the number of students in the first period class. It is impossible for the number of students in the class to go on indefinitely.

Discrete random variable has the following properties:

It is finite
It is numeric
It is countable
It contains non-negative integers.

A continous random variable is a variable that has an infinite number.

The area of a circle A is 85π ft2. ∠BAC is a central angle of the circle, and m∠BAC = 36°

BlackZzzverrR [31]

As stated the area of the circle is 85π ft2. The area of the sector BAC is a portion of this full circle area. the sector is made of 2 radii and arc that has rotated by 36°.
the magnitude of the central angle in the circle is 360°
Area for 360° central angle -  85π ft2
then the area for 1° =  85π ft2/360°
the area of 36° sector =  85π ft2/360° x 36°
=  8.5π ft2

Dylan scores a total of 48 points in his first games of the basketball season. Which equation can be used to find g, the average

Anarel [89]

Answer: 48÷4 = g

Step-by-step explanation:

Here is the complete question:

Dylan scored a total of 48 points in first 4 games of the basketball season. Which equation can be used to find g, the average number of points he scores per game?

a. 48÷4=g

b. 4÷48=g

c. g÷4=g

d. 4÷g=48

The average number of points Dylan scores per game which has been represented by g will be the total points scored divided by the number of game played. This will be:

g = total point scored ÷ number of games played

g = 48 ÷ 4

Therefore, option A is the right answer.
