Understanding PolymorphismObject-oriented programming or OOP has several important pillars. You must understand this. Among them are class, object, method, and inheritance.
Polymorphism is divided into two syllables namely, Poly which means many and Morphism which means form. In science, polymorphism is a principle in biology in which organisms or species have many forms and stages. This principle is also applied to the Java language.
Polymorphism in OOP is an OOP concept where class has many "forms" of different methods, even though the names are the same. The meaning of "form" is that the contents are different, but the data types and parameters are different.
Polymorphism can also be interpreted as a programming technique that directs you to program in general rather than specifically. For example, we have three different classes: “Rabbit”, “Cat”, and “Cow”. Where the three class are derived from class "Animal".

The main difference between other spreadsheet models and simulation models is that the input variable cells in the simulation contain random numbers.
Random Numbers in Simulation Modeling
As the term suggests, random numbers are numbers that are chosen by chance at random, from a pool of numbers. All numbers in a given distribution have the same probability of being randomly selected.
Random numbers appear in a given distribution only when two conditions are met: Values are evenly distributed over a given interval or series, and it is impossible to predict future values based on past or present.
For numbers in sequence or distribution to be truly random, they must be independent. Numeral independence means that there is no correlation between successive numbers. In addition, these numbers should appear in the distribution with approximately the same frequency.

Explanation:
If, as a result of inappropriate use of the strategic management process, performance data and activity reports indicate undesirable performance, then operational managers must: *
know about it so that they can correct the employee activity.
change the strategic management model.
immediately notify the board of directors.
allow sufficient time to pass to verify if it is the process or just the usage that is the problem.
check the performance data to ensure their accuracy and take two more measurements.
Option a is correct. They are aware of it and can change the employee's behavior.
Setting goals or objectives, conducting analysis, developing a plan, putting that strategy into action, and monitoring that approach are the five stages of the process. The strategic management approach entails more than just adhering to a set of guidelines. It is a way of doing business that is philosophical.
A field of management that deals with an organization's strategic goals is referred to as strategic management. This could involve creating the organization's vision, defining its operational goals, and developing and putting into practice the organization's strategy. Depending on the situation, it might also involve developing and implementing deviation correction measures. Strategic planning, a related but entirely independent field of management, should not be confused with the strategic management process.

The host bits and network bits are both set to all 0s to generate a 32-bit value known as a subnet mask. The subnet mask delineates the network and host addresses in the IP address in this manner.
Each device has a unique IP address that is made up of two parts: the client or host address and the server or network address. A DHCP server or a human being must either manually or automatically configure IP addresses (static IP addresses).
The subnet mask separates the IP address into the host and network addresses, designating which parts of the IP address belong to the network and which parts belong to the device.

The number of places at which two corresponding bits of data can differ is known in information technology as the Hamming distance. It is frequently employed in a variety of mistake correction processes or in the evaluation of opposing strings of data or pieces of information.
Hamming codes are perfect codes because they have a minimum distance of three and a block length that results in the highest achievable rate for codes. In order to automatically repair errors caused by punched card readers, Richard W. Hamming created the Hamming codes in 1950.

You've just started a new job as a data analyst. You're working for a midsized pharmacy chain with 38 stores in the American Southwest. Your supervisor shares a new data analysis project with you.
She explains that the pharmacy is considering discontinuing a bubble bath product called Splashtastic. Your supervisor wants you to analyze sales data and determine what percentage of each store's total daily sales come from that product. Then, you'll present your findings to leadership.
You know that it's important to follow each step of the data analysis process: ask, prepare, process, analyze, share, and act. So, you begin by defining the problem and making sure you fully understand stakeholder expectations.
One of the questions you ask is where to find the dataset you'll be working with. Your supervisor explains that the company database has all the information you need.
Next, you continue to the prepare step. You access the database and write a query to retrieve data about Splashtastic. You notice that there are only 38 rows of data, representing the company's 38 stores. In addition, your dataset contains five columns: Store Number, Average Daily Customers, Average Daily Splashtastic Sales (Units), Average Daily Splashtastic Sales (Dollars), and Average Total Daily Sales (All Products).
You know that spreadsheets work well for processing and analyzing a small dataset, like the one you're using. To get the data from the database into a spreadsheet, what should you do?
Download the data as a .CSV file, then import it into a spreadsheet.
Using the knowledge in computational language in python it is possible to write a code that dataset contains five columns: Store Number, Average Daily Customers, Average Daily Splashtastic Sales (Units), Average Daily Splashtastic Sales (Dollars), and Average Total Daily Sales (All Products).
