A random variable can be either discrete or continuous. It is discrete it can assume only a finite number of values, or a countable infinity of values at most.
It is continuous if it can assume values in an interval, or in general, an uncountable infinity of values.
That being said, we have:
Option A is a discrete random variable, because the number of heads in 5 throws can be 0, 1, 2, 3, 4 or 5. So, we have finitely many possible values.
Option B is a discrete random variable, because the number you roll on a die is either1, 2, 3, 4, 5 or 6. So, we have finitely many possible values.
Option C is a discrete random variable, because if there are n students in a class, the number of boys is an integer between 0 and n. So, we have finitely many possible values.
Option D is finally a continuous random variable, because the height of a 10-year-old can be any number (in a suitable range of course).
Answer:
80 bc if you look at the other side its the same so it would have to be 80
Step-by-step explanation:
Answer:
Here, 
denotes the number of roses used for a school celebration and 
denotes the number of carnations used for a school celebration.
Step-by-step explanation:
Let denotes the number of roses used for a school celebration and denotes the number of carnations used for a school celebration.
Cost of 1 rose = $1.45
Cost of roses = 
Cost of 1 carnation = $0.65
Cost of roses = 
Total cost spend on flowers = 
Total amount with Jaida = $200
So,
the inequality to represent the cost constraint is
