Draw a graph that models the connecting relationships in the floorplan below. The vertices represent the rooms and the edges represent doorways connecting the rooms. Vertex F represents the outdoors. F ㅓㅏ A B T E Is it possible to find a circuit through the house that uses each doorway once? If so, enter the sequence of rooms (vertices) visited, for example ABDEA. If it is not possible, enter DNE.

Consider the tree diagram. Path number 1 B1 C2 2 4 C2 4 4 4 B3 6 3 Find P(C,|B2) · P(B2). (Enter your answer as a fraction.)

Identify all edges on the graph that are bridges. E B. ..... The edges are bridges. (Use a comma to separate answers as needed.)

Enter the labels of each vertex in the order visited in a post-order traversal.

Read all directions before answering a question. This assignment is conceptual in nature so no work is needed BUT be sure to be clear and state all answers in complete sentences where needed. Write answers on this sheet. 1) Determine how many vertices and edges the graph has and the degree of each vertex. State the degree next to the vertex OR state the vertex label letter and the degree in the space to the right of the graph. A B E с D # of vertices = # of edges =

Q1: How many vertices does this object show   Q2: How many vertices does this object have

Someone is thinking of a connected graph in the plane. It is made of 36 edges and cuts theplane into 18 regions.  How many vertices are there?
