Answer:

The number of cars passing a tollbooth in a given hour.

Step-by-step explanation:

Discrete variable is a variable that possess a countable number of values, means the value is obtained by counting.

1. the average annual increase in fuel price  - This is not discrete as the values can be decimal. And it is obtained by measuring, so it is continuous variable.

2. a car's speed at different times  - This is also not discrete. This is also continuous variable.

3. a person's weight - This is also not discrete.

4. the number of cars passing a tollbooth in a given hour  - This is discrete as we can count the number of cars.

  • The sides are congruent.
  • All the opposite sides are parallel to each other.
  • Diagonals bisect each other perpendicularly.
  • The angles are supplementary, that is, they add up to 180°

If Rhombus RSTU is congruent to WXYZ, then they are both translation images of each other because all their sides and angles are equal.
