Note: You will find the Example videos in the module very helpful in answering these questions. Please type or write only a number or text in the text box provided. Use the Activity-on-Arrow (AOA) diagram on the following page to determine the following -each number is the number of hours for the task. \begin{tabular}{|c|c|c|} \hline & \begin{tabular}{l} How many different paths are there through the network? (15 \\ oints) \end{tabular} & \\ \hline & What is the number of the last node in the network? (15 points) & \\ \hline & \begin{tabular}{l} What is the difference in hours taken for the two paths when they \\ onnect at node 10 . ( 15 points) \end{tabular} & \\ \hline & \begin{tabular}{l} What is the difference in hours taken for the two paths when they \\ onnect at node 12 . ( 15 points) \end{tabular} & \\ \hline & What is the expected duration of the entire project? (15 points) & \\ \hline & What is the critical path? Separate each node with a dash (). & (12.5 points) \\ \hline & Which is the longest path? Separate each node with a dash (). & (12.5 points) \\ \hline \end{tabular}
