Answer:
The answer is the last choice that is "None of these values will produce a mathematical error".
Explanation:
In this question, the above given choice correct because neither of the flowchart procedures could trigger a mathematical error. This error could not be induced by multiplication, addition and subtraction, and the only division by 15. It is the only divide by 0, that's why the above flowchart will produce a mathematical error.
Answer:
D)One big superclass can be used instead of many little classes.
Explanation:
Inheritance could be described as getting new class on another existing class with almost same execution,
inheritance allows codes to be re-used. It should be noted that inheritance bring about the code sharing among class.
The advantages of using inheritance includes but not limited to
✓ Code that is shared between classes needs to be written only once.
✓Similar classes can be made to behave consistently.
✓ Enhancements to a base class will automatically be applied to derived classes.

Explanation:
demo.java Shapes 2 Shapes Polymorphism Create a set of classes derived from an abstract class Shape, which provides a common interface, for managing various 2D geometric shapes. In our model, each Java object will represent a shape somewhere in a Cartesian coordinate system. However, note that unlike in Mathematics, the positive y-axis grows down from the origin. Shapes All shapes have the following properties: color, area, perimeter, location, and bounds. Shapes are mutable, for example any shape can be moved.
