Solution Steps

Step 1: Identify the relationship type

The UML class diagram shows a relationship between Employee and Vehicle with multiplicities of 0..1 on both ends. This means that an Employee can have zero or one Vehicle, and a Vehicle can be associated with zero or one Employee.

Step 2: Interpret the multiplicities

The multiplicity 0..1 on both sides indicates that the relationship is optional for both entities. Neither the Employee nor the Vehicle is required to have a counterpart in the relationship.

Step 3: Determine the best description

Given the multiplicities 0..1 on both sides, the best description of the relationship is "Zero-to-one," as it accurately reflects that each Employee can have zero or one Vehicle and vice versa.

Final Answer

Zero-to-one

For each planet in a solar system, its year is the time it takes the planet to revolve around the center star. The formula E=0.2 x^(3 / 2) models the number of Earth days in a planet's year, E, where x is the average distance of the planet from the center star, in millions of kilometers. There are approximately 224.8 Earth days in the year of Planet B. What is the average distance of Planet B from the center star?
