how is it possible that these classes can provide behavior when they have no code in the body of the class?
Answers
Therefore, while interfaces can be used to indicate the common functionality that will be shared between multiple instances without actually constructing that functionality for them, abstract classes can be used to group and share functionality. Both can, albeit in different ways, assist you in shrinking your code.
Which methods may the child class inherit?
You can use the inherited methods exactly how they are right now. You can override a superclass method by creating a new instance method in the subclass that has the same signature. To conceal it, a new static method with the same signature as the one in the superclass might be written and placed in the subclass.
What real-world instance of abstraction can you give?
A few further examples of abstraction from the real world are as follows: cake baking Abstraction is used when following a recipe to make a cake. In this case, you are merely completing the processes required to make and bake the batter.

Bias can be very difficult to overcome. For instance, social networks help people get jobs. While this benefits some, it means that it is harder for those outside the network. Why does this contribute to a lack of diversity in hiring?.
Answers
This contributes to a lack of diversity in hiring because the people who are part of the social network tend to have similar backgrounds, experiences, and networks.
What is networks?
Networks are a collection of computers, servers, and other connected devices that are able to communicate with one another using a set of protocols and standards. A network can be as small as a personal computer connected to the internet or as large as a global network of interconnected computers and servers. Networks allow users to share information and resources such as files, data, messages, emails, and applications.
This means that they are more likely to recommend people who look and think like them, rather than reaching out to a more diverse pool of candidates. This perpetuates existing biases, as people are less likely to consider candidates who don't fit their preconceived notions of who would be a good fit. As a result, hiring pools are not as diverse as they could be, leading to a lack of diversity in hiring.

One form of subnet masking uses a technique called Variable Length Subnet Masking (VLSM) and permits a single address to be subdivided into multiple subnets, where the subnets do not need to be the same size.
Here,
VLSM allows for efficient use of IP addresses by allocating different subnet sizes based on the requirements of each subnet. This technique is commonly used in modern networks to optimize address allocation and maximize network efficiency.
With VLSM, subnet masks can have varying lengths, which means subnets can have different numbers of available addresses. This flexibility allows for better utilization of IP addresses and more efficient network management.
Therefore correct terminology is VLSM.

We mentioned in our class that large prime numbers are used in message encryption. In this worksheet, let's have a quick glance of RSA encryption, which is one of the oldest and most widely used encryption schemes. RSA encryption consists of two main stages: encryption (or scramble) and decryption (or unscramble). In brief, the encoded plain-text message is translated into a cipher using a public key during encryption, and the decryption recovers the plain-text message later on using a secret key. In this worksheet, we encode characters in plain-text messages alphabetically into 0∼25 (e.g., 0318 for "DS") and decode accordingly. Encryption Stage Take two primes p and q. (In practice, p and q are very large primes. In this worksheet, we use small number for simplicity.). Set n=pq and pick an e that is relatively prime to (p−1)(q−1). The value pair (n,e) is the public encryption key. You can give this to anyone and they can encrypt data as follows: - Take any integer 0
e
modn In this worksheet, we use p=43,q=59 and e=13. Problem 1. Show that p is prime using trial division. When justifying, show the remainders and quotients. Problem 2. We write a≡bmodn if (amodn)=(bmodn). All we're saying here is that a and b have the same remainder when divided by n. Prove that a≡bmodn if and only if a−b≡0modn if and only if n∣(a−b). (Hint: Rewrite them into quotients and remainders first using The Division Algorithm)
Answers
In RSA encryption, large prime numbers are used to generate the public and secret keys for encryption and decryption.
The encryption stage involves selecting two prime numbers, p, and q, multiplying them to obtain n, and choosing a value e that is relatively prime to (p-1)(q-1) to form the public key. The plaintext message is encoded into a cipher using the public key, and the decryption stage uses the secret key to recover the original message. In this worksheet, the values p=43, q=59, and e=13 are used. Problem 1 requires demonstrating that p is prime using trial division, and Problem 2 involves proving the equivalence of congruence and divisibility in modular arithmetic. In Problem 1, trial division is used to check if p is prime by dividing it by numbers less than p and checking for any remainders other than 0. If no non-zero remainders are found, p is proven to be prime. In Problem 2, the concept of congruence (a≡body) is explained, indicating that a and b have the same remainder when divided by n. The equivalence between congruence, the difference (a-b) being congruent to 0 mod n, and n dividing (a-b) is proven using the Division Algorithm, which involves expressing a and b as quotients and remainders.

B. designers do not have to be creative
C. businesses have more control over their designs
D. Time and materials are saved
Answers
Answer:
The correct statement that supports the benefits of computer-aided design (CAD) is "time and materials are saved."
Explanation:
CAD allows designers to create and modify designs quickly and easily using a computer, rather than having to create physical prototypes or drawings. This can significantly reduce the time and materials needed to create and revise designs, as changes can be made digitally rather than having to create new physical models or drawings.
Option A ("privacy is increased") is not a benefit of CAD.
Option B ("designers do not have to be creative") is incorrect because CAD does not replace the need for creativity and design skills.
Option C ("businesses have more control over their designs") is a potential benefit of CAD, but it is not the primary benefit of the technology.

Relational DBMS like Oracle A Document-based database like MongoDB A graph-based database like Neo4j A key-value pairs database like Redis A wide-column-based database like Cassandra
Answers
The database backend for storing information about teams and games in AFL would be a relational DBMS like Oracle. A relational database management system is a type of database management system (DBMS) that stores data in a tabular form of rows and columns.
Relational database management systems provide the ability to manage large amounts of data effectively and efficiently. They provide support for structured query language (SQL) for accessing and manipulating data in the database. The structure of the AFL data with teams, games, and other information can be represented using tables in a relational database.
For example, there can be a table for teams with columns for team names, locations, and other information. Another table can be created for games with columns for game ID, home team, away team, and game date. Relational databases are well-suited for applications that require complex querying and data manipulation, such as generating reports or statistical analysis.
They also offer support for transactions, concurrency control, and backup and recovery. Relational DBMS like Oracle is the best choice for storing information about teams and games in AFL.

In neighbourhood A, there is only one SPA center called JBI SPA. JBI provides a SPA service to their customers where most of whom are living in this neighbourhood and have been contacting with JBI SPA for many years. JBI's demand curve is: P = 30 - Q, and JBI's marginal cost of service is: MC = 4Q. JBI charges a single price for a unit of service.
At profit maximization level, calculate the following:
a) Price Level:_____
b) Output level:_____
c) Consumer surplus: _____
d) If JBI enforces first-degree price discrimination, the lowest priced charged is: ____ and the output level is: _____
e) Ignoring any fixed costs and under perfect price discrimination, JBI's total profit is:_____
Answers
At profit maximization level, the price level, output level and consumer surplus is given as follows:a) Price Level:The profit maximization condition of JBI Spa is given by MR = MC.Substitute the value of MR in terms of P, we have;P/2 = surplus:Consumer surplus (CS) is the difference between what the customers are willing to pay for a good or service and the actual price they pay for it.
The formula for consumer surplus is given as;CS = 0.5 * (Pmax - P) * Q, where Pmax = 30.Substitute the values of P, Pmax, and Q in the above formula, we get;CS = 0.5 * (30 - 8Q*) * Q*CS = 0.5 * (30 - 8(3.33)) * 3.33CS = $37.17d) If JBI enforces first-degree price discrimination, the lowest priced charged is and the output level is:The lowest price charged under first-degree price discrimination is the reservation price, which is equal to the maximum amount of money each customer is willing to pay for the service.
Since most of JBI's customers have been contacting with JBI Spa for many years, we can assume that their maximum willingness to pay is not too different from the price they are currently paying.So, the reservation price under first-degree price discrimination is equal to the current price level, which is P* = 8Q*.The output level under first-degree under perfect price discrimination, JBI's total profit is:Under perfect price discrimination, JBI can extract all the consumer surplus from its customers, which means P = MC = 4Q*.Substitute Q* = 3.33 in the above equation, we have;P = 4(3.33) = $13.33JBI's total profit under perfect price discrimination is equal to the total revenue which is given as;Total revenue = P * Q* = 13.33 * 3.33Total revenue = $44.45Thus, ignoring any fixed costs and under perfect price discrimination, JBI's total profit is $44.45.

The wrap text feature is an essential tool used to format text, particularly long texts or data within a cell in Microsoft Excel. In this question, we need to explain the difference between how wrap text behaves in Microsoft Excel versus how it is used in Microsoft Word.
Wrap Text in Microsoft Excel: Wrap text in Excel is a formatting option that is used to adjust text or data within a cell. When the text entered exceeds the size of the cell, it can be hard to read, and this is where wrap text comes in handy. Wrap text in Excel automatically formats the data within the cell and adjusts the text size to fit the cell's width. If a cell contains too much data to fit in the column, the cell's text wraps to the next line within the same cell.
To wrap text in Excel, follow these simple steps:
Select the cell or range of cells containing the text that needs wrapping. Right-click on the selected cell and click Format Cells. In the Format Cells dialog box, click on the Alignment tab. Click the Wrap text option and then click OK.Wrap Text in Microsoft Word: In Microsoft Word, the Wrap Text feature is used to format text around images and graphics. It is used to change the way the text flows around the image, allowing users to position images and graphics in the document. Wrap Text in Microsoft Word does not adjust the font size of the text to fit the width of the cell like in Excel.
To wrap text in Microsoft Word, follow these simple steps:
Insert the image in the document. Select the image and go to the Picture Format tab. Click on Wrap Text, and you can choose how you want the text to wrap around the image.The main difference between the use of Wrap Text in Microsoft Excel and Microsoft Word is that Wrap Text in Excel is used to format long data and adjust text size to fit the width of the cell while Wrap Text in Microsoft Word is used to format text around images and graphics.
