Answer:
d. 10
Step-by-step explanation:
A variable that can only take on specific numeric values is called A discrete random variable.
According to the statement
A variable which is used to select a specific numeric value and we have to find a those variable
A discrete random variable is one which may take on only a countable number of distinct values.
So, A variable that can only take on specific numeric values is called A discrete random variable.

In 7th grade:
red-hair students =58
another color hair students =609
In 8th grade:
red-hair students =60
Let's assume
another color hair students =x
now, we are given
The numbers of red-haired students in 8th grade are proportional to the numbers in 7th
so,
now, we can solve for x
we get
we get
so, students have another color hair in 8th grade is 630.........Answer
Correct option is C. There are 20 ordered pairs.
Given that ordered pairs (x,y)
such that x is even integer where 4≤x≤10 and y is an integer.
where 4<y<10.
Then even integer 4≤x≤10 are four i:e
4,6,8,10
And integer 4<y<10 are five i:e
5,6,7,8,9
Then ordered pair are = 4×5=20
<h3>What are ordered pairs?</h3>
An ordered pair is a composition of the x coordinate (abscissa) and the y coordinate (ordinate), having two values written in a fixed order within parentheses. It helps to locate a point on the Cartesian plane for better visual comprehension. The numeric values in an ordered pair can be integers or fractions.
