Bond X is noncallable and has 20 years to maturity, a 10% annual coupon, and a $1,000 par value. Your required return on Bond X is 11%; if you buy it, you plan to hold it for 5 years. You (and the market) have expectations that in 5 years, the yield to maturity on a 15-year bond with similar risk will be 9.5%. How much should you be willing to pay for Bond X today? (Hint: You will need to know how much the bond will be worth at the end of 5 years.) Do not round intermediate calculations. Round your answer to the nearest cent.

Host A and Host B will be able to communicate directly without an intervening router.

10. A Host (the sending host) is trying to send a packet to another host (the destination host). The sending host knows the IP address of destination host. In deciding how to forward the packet toward destination host, the sending host will:

take the Destination IP address and perform a Logical AND operation with its own (sending hosts') Network Mask to determine if the destination host is on the same network as the sending host.

take the Destination IP address and perform a Logical AND operation with destination host's Network Mask to determine if the destination host is on the same network as the sending host.

always forward all packets to the default gateway and not be concerned with determining if the destination host is on the same network as the sending host.

never forward any packets to the default gateway and not be concerned with determining if the destination host is on the same network as the sending host.

Requirement: To create three classes, Account, Transaction, and the main class (with the main method). Please closely follow the requirements below. I only need to know how to create the menu and be able to use it through out the code.

Requirements for the Transaction class: A private Date data field that stores the date of the transaction  A private char data field for the type of the transaction, such as “W” for withdrawal and “D” for deposit  A private double data field for the amount of the transaction  A private double data field for the balance of the account after the transaction  A private String data field for the description of the transaction  A constructor that creates an instance of the Transaction class with specified values of transaction type, amount, balance, and description, and date of the transaction. Note: Instead of passing a Date object to the constructor, you should use the new operator inside the body of the constructor to pass a new Date instance to the date data field. Define the corresponding accessor (get) methods to access a transaction’s date, type, amount, description, and the balance, i.e., you need to define 5 get methods.  Define a toString() method which does not receive parameters but returns a String that summarizes the transaction details, including transaction type, amount, balance after transaction, description of the transaction, and transaction date. You can organize and format the returned String in your own way, but you have to include all of the required information. Note: the purpose of the Transaction class is to describe (record) a banking transaction, i.e., when a transaction happens, you can use the transaction parameters to create an instance of the Transaction class.

Requirements for the Account class:  A private int data field for the id of the account.  A private String data field that stores the name of the customer.  A private double data field for the balance of the account.  A private double data field that stores the current annual interest rate. Key assumptions: (1) all accounts created following this class construct share the same interest rate. (2) While the annual interest rate is a percentage, e. g., 4.5%, but users will instead enter the double number as 4.5. Therefore, you need to divide the annual interest rate by 100 whenever you use it in a calculation.  A private Date data field that stores the account creating date.  A private ArrayList data field that stores a list of transactions for the account. Each element of this ArrayList has to be an instance of the Transaction class defined above.  A no-arg constructor that creates a default account with default variable values.  A constructor that creates an instance of the Account class with a specified id and initial balance.  A constructor that creates an instance of the Account class with a specified id, name, and initial balance. Note: for all constructors, instead of passing a Date object to the constructor, you should use the new operator inside the body of the constructor to pass a new Date instance to the date data field.  Define corresponding accessor (get) and mutator (set) methods to access and reset the account id, balance, and interest rate, i.e., you need to define 3 get methods and 3 set methods. Define corresponding accessor (get) methods to access the account name, transactions, and date created information, i.e., you need to define 3 get methods  Define a method named getMonthlyInterest() that returns the monthly interest earned.  Define a method named withdraw that withdraws a specified amount for a specified purpose from the account and then add this transaction including its description to the ArrayList of transactions.  Define a method named deposit that deposits a specified amount from a specified source to the account and then then add this transaction including its description to the ArrayList of transactions.

Notes: (1) The method getMonthlyInterest() is to return monthly interest earned, not the interest rate. Monthly interest = balance * monthlyInterestRate, where monthlyInterestRate = annualInterestRate/12. (2) The constructors for the Account class will initiate the date data field. (3) You should create the Account and Transaction classes as independent files in the same package of your main class. Requirements for the main class: To test the two classes above, in the main method of your main class you need to do the following first:  Create an instance of the Account class with an annual interest rate of 1.5%, a balance of 1000, an id of 1122, and a name as George.  Deposit $3000 as salary to the account and then withdraw $2500 as rent from the account.

 Print an account summary that shows the account holder’s name, annual interest rate, balance, monthly interest, the date when this account was created, and all transactions. (Check the results of this print statement to verify that your Account and Transaction classes work properly.)  After you pass the above test, continue on to do the rest. Simulate an ATM machine experience: The ATM system will ask users to enter a valid ID first (corresponding to user login). If the entered ID matches to one of the Accounts’ ID, the system will present the user an ATM main menu.

Description of the ATM machine main menu: This ATM machine main menu offers users four choices: choice 1 for viewing the current balance, 2 for withdrawing money, 3 for depositing money, and 4 for exiting the main menu (corresponding to user logoff).  The ATM main menu prompts the user to enter a choice, and depending on the user’s choice it may ask for additional input (i.e., withdraw or deposit amount) before acting on the user’s choice.  Your code should behave properly for each user choice as shown in the sample-run figure at the end.  Description of the sample-run figure (shown at the end): In the sample-run figure below, the user first entered a choice 1 for viewing the current balance, and after hitting the Enter key a statement of balance was shown. Then the user entered 2 for withdrawing money, and after hitting the Enter key the system asked the user to enter the withdraw amount. The user next entered 1 to verify the balance amount. Afterward, the user entered 3 for depositing money, and after hitting the Enter key the system asked the user to enter the deposit amount. Again, The user next entered 1 to verify the balance amount. Lastly, the user entered 4 for exiting the main menu and the system responses by prompting for an id again. In the main method, create an Array of ten accounts with account IDs as 1, 2,. . . , 10, and an initial balance of $100 for each account. You will use this Array to simulate an ATM machine experience in the main method. To do that, you need a Scanner to capture the user’s input and define a few variables. You should also define a few methods in the main class, to be used inside the main method, to make the main method looks lean. There are many options to choose from, and the objective is to model an ATM machine experience described above. Additional simulation requirements: After creating the 10-element array (and a few variables), the system should prompt the user to enter an ID and it will verify if the ID is a valid one. An ID is valid if it matches to one of the accounts of the 10-element Array. If the ID is valid, the ATM main menu (described above) is displayed; otherwise the system will ask the user to enter a correct ID. That is, the system will not present the ATM main menu until the user enters a correct ID. You may have noticed that based on the above ATM simulation description, once the system starts it will not stop because after a user chooses option 4 to exit the ATM system will ask user to enter an ID again. To give users an option exiting the system after a few rounds of ATM simulation, inform users that when entering an ID, enter 0 to exit the ATM run (since valid ids are from 1 to 10). That is, if users enter 0 as ID, instead of showing the main menu, the system will terminate the project, but before that it will print out all ATM transactions for each account (in the Array) that actually incurred transactions.

Whenever Mr. Kerrigan picked up his young son, Billie, from soccer practice he would have to drive past a Dairy Queen. Every time Billie saw the large Dairy Queen sign, Billie would begin to scream. Mr. Kerrigan did not like his son’s screaming. To make his son stop screaming for ice cream, Mr. Kerrigan would pull over and buy ice cream for Billie. This stopped Billie’s screaming. In this short example, what is an example of positive reinforcement? What is an example of negative reinforcement? (Hint: both Billie and his dad are being conditioned in this story). How could Billie’s dad use conditioning to prevent Billie from screaming in the future?
