Q.1/Draw an activity diagram for the following scenario: Passenger who needs to purchase a travel ticket initiates the activity. He she will be asked for trip information by the ticket machine. This information includes number and type of tickets, such as monthly pass, one way or round ticket. Based on the provided information. the ticket machine will compute payment then asked for payment choices. The passenger can pay with cash, credit card, or Zain cash. If the passenger chooses to pay by card. Bank (another actor) will engage in the activity in order to authorize the payment. After the payment is complete, the ticket is given to the passenger and the ticket machine will show "Thank You" message at the end of the activity.

Task 4 Develop a class diagram for following description: Develop a class diagram for following description: The telephone agent uses an order registry and customer catalog to obtain access to an order & a customer respectively. The order registry uses an order number as a qualifier to select particular order instance. A customer catalog uses customer name and phone number as a qualifier to select particular customer. The attributes of an order are the order numbers and time when it is placed. The order consists of many items. An item has item_number, a quantity, unit price. It also has reference to catalog item which represents listing. When an order is cancelled or corrmitted, it cancels or commits each of its items first. When an order's total price method is invoked, the order calls the total price method of each of items and returns the sum.
Correct answer will be upvoted else downvoted. speed up development the game has n quick travel towers. I-th tower is situated at area (xai,yai). To have the option to quickly venture out to the pinnacle from any area in the game world it should initially be actuated. Initiation of pinnacle I occurs right when the player is in cell (xai,yai) after this the pinnacle stays dynamic all through the whole game. William additionally realizes that the game has m missions. I-th journey can be finished immediately by being at area (xbi,ybi) on turn ti. William needs to discover the maximal number of missions he will actually want to finish by ideally navigating the game world. Input :The main line contains two integers n and m (0≤n≤14,1≤m≤100), which are the number of pinnacles and the number of journeys, individually. Every one of the following n lines contains two integers xai,yai (1≤xai,yai≤106), which are the directions of quick travel towers. Every one of the following m…

A Train ticket selling machine works as follows: A customer who wants to buy a ticket for a particular journey enters the destination, the station to start from, the date and time of departure, the class in which he wants to travel. The information system which returns data about one or more possible trips matching the query. Each trip is described by its number, date of departure, exact time of departure, time of arrival, and price. The customer chooses one of the possible trips found by the system and reserves a seat or more in this trip by getting a ticket for it. The ticket contains some further information such as the date of issue. Before the customer receives one or more tickets, he has to pay for them. The system supports two different methods of payment - pay by credit card or by inserting bank notes. If you pay by credit card, the system registers the number of the credit card and its expiration date. Independent of the payment method the customer chooses, the system…
1. Draw a UML usecase diagram of the Habit tracker. A habit tracker is designed for ease of users to track daily behaviors. The application allows the user to add a habit. Each time the user adds any habit, the habit history is updated. When the user perform his habit, he mark the habit as done today and can also add a comment only if he wants. And the same is updated the habit history. A user is also allowed to delete a habit. Each time a habit is deleted the habit history is Updated. Both the user and a coach is allowed to list habits and view the habit history. In habit history view, single habit check-in can also be viewed. However, the coach is also allowed to list all the users and can view one user's habit separately if he wants (Non-anonymous questionO) .

In the resulting DFA what state is transitioned to from state "be" when consuming a 0? In the resulting DFA what state is transitioned to from state "be" when consuming a 1? Note: This question is hypothetical and does not require that you construct the whole DFA. Simply assume there is a state "be" and determine where the 0 and 1 arrows would transition.
Sequence diagram Create a UML sequence diagram that will show your clients how the system’s classes will interact when customers are buying their flight tickets on the booking website. How to create your assignment Review the code responsible for adding a new item. Make a sequence diagram that captures the interactions of objects in the app when a new item is added. Your sequence diagram should contain the following classes: AddItemActivity ItemList Dimensions Item And contain calls of the following methods: onCreate() loadItems() saveItem() Dimensions constructor Item constructor addItem() saveItems() Lastly, the activation of AddItemActivity should start with the call to “onCreate()”
Description: In a hypothetical class, students take two midterms and an optional final. If a student takes the final and gets in it a better score than the lowest of the two midterm scores, then the lowest midterm score would be replaced by the comprehensive final score. The overall score will then be calculated by averaging the three test scores. If the student does not take the optional final, the overall score is calculated using only the two midterm scores. Students’ exam scores are included in the “Question1” tab in the attached worksheet. Empty data entries for the optional comprehensive final means that the student did not take the optional final. Tasks: Task 1: In Question1_Module, code a function that requires midterm1 score, midterm2 score, and comprehensive final as inputs and calculate the overall score per the description above. Task 2: In Question1_Module, code a Sub that uses the function coded in task 1 to fill column ‘I’ of the worksheet and link this…
