Numeric Keypad is the answer
So in developing a presentation outline, the first thing that we are going to do is to introduce what it is all about. This means that the main points come first. After the main points, follow the sub points. The sub points serve as the explanation of the main points. After the sub points are the illustrations and examples. These are already the specifics which support the sub points and the main points. Therefore, the answer is A.
Answer:
B. n-1
Explanation:
If there are n vertices then that vertex can be origin of at most n-1 edges.Suppose that you have a graph with 8 vertices you can select a vertex from these 8 vertices now you have 7 other vertices.So the vertex you selected can have at most 7 edges or it can be origin of at most 7 edges.So we conclude that the answer is n-1.
