Arrows on a line mean that the line continues forever in that direction. If there are two arrows in both directions along a line, then you have a geometric line. If you only have one arrow, then it is a ray. Having no arrows indicates a segment.
Answer:
hours worked at job, number of siblings are examples of discrete random variable.
Step-by-step explanation:
Discrete random variable has values that can be counted. It has finite data that does not change continuously.
Hours worked at a job can be counted at the end of the day.
The weight of a child keeps changing continuously therefore it is not a discrete random variable.
Number of siblings can be counted.
The length of a fish can keep changing day by day therefore it is not a discrete random variable.

5/20 = 1/4. All the rest of the fractions reduce to 1/5.
Answer:
There are 16 integers between -3.92 and 12.4
Step-by-step explanation:
If we want to find the integers between two numbers we just need to subtract the integer numbers of the interval.
The integer interval will be:
![[-3,12]](https://tex.z-dn.net/?f=%5B-3%2C12%5D)
Now, we subtract them:
Let's recall that 0 is an integer
Therefore, the answer will be 16.
I hope it helps you!
