Jaslene Casey · Answer 1

mathClass = Roster ([ ('Jacob', 65), ('Frankie', 86), ('Lina', 94), ('Arnold', 63), ('Amanda', 87) ])

Explanation:

An Instance of a class, refers to making a new object of that class. They belong to the class from which they are derived. The meaning of this is that every instance of a class that is created, will have its own set of variables with different values initialized by the constructor call, so we can make several objects of a class and define their behavior. In this question, we are asked to make a new instance of the class Roster called mathClass and at the constructor call we pass the variables of this new object as an argument.
