C4 C1,C3 represents a transitive dependency, because C4 is functionally dependent on C3.
What is transitive dependency?Transitive dependency is a type of dependency that exists between three different objects. It occurs when changes to one object affect a second object, which in turn affects a third object. This type of dependency can be seen in databases, software, and programming languages. In databases, transitive dependency occurs when a change to a primary key affects a foreign key, which in turn affects a second foreign key. In software and programming languages, transitive dependency occurs when a code change affects a library, which in turn affects a program. Transitive dependency is an important concept to understand when developing software, as it can have a significant impact on the overall performance of a system.

6. Create a SQL query that for the employee Nathan Geller will identify the projects he’s associated with. List the project ID, employee ID, employee last name and project start date for all projects whose assigned employee’s last name is Geller
Answers
Answer:
This query uses a JOIN operation to combine the "projects" and "employees" tables based on the "employee_id" foreign key. The WHERE clause filters the results to only include projects where the assigned employee's last name is "Geller" and first name is "Nathan". The SELECT clause specifies which columns to include in the output: "project_id" from the "projects" table, "employee_id" and "last_name" from the "employees" table, and "start_date" from the "projects" table.
SQL Query
SELECT projects.project_id, employees.employee_id, employees.last_name, projects.start_date

Answers
Note that a Java statement that assigns the number of one-dollar bills to variable numOnes given amountToChange is given below.
int numOnes = amountToChange % 5;
What is the explanation for the above?This statement uses the modulus operator, %, to calculate the remainder when amountToChange is divided by 5.
This remainder represents the amount of money that cannot be evenly divided into five dollar bills, and therefore must be given in one dollar bills. The result is assigned to the variable numOnes.

compare and contrast the school of digital age and that of industrial age
Answers
The school of digital age represents a significant departure from the school of the industrial age.
Compare the digital age and industrial age schools?
The school of the digital age and the school of the industrial age differ in several ways.
Curriculum and teaching methods: The school of the industrial age focused on rote learning, memorization, and standardized testing. The curriculum was based on a set of core subjects, such as reading, writing, math, and science. In contrast, the school of the digital age emphasizes problem-solving, critical thinking, creativity, collaboration, and digital literacy. The curriculum is often personalized, interdisciplinary, and project-based. The teaching methods include online learning, blended learning, flipped classroom, and adaptive learning.Technology and resources: The school of the industrial age used traditional resources, such as textbooks, chalkboards, and pencils. Technology was not a major part of the learning environment. In contrast, the school of the digital age relies heavily on technology, such as laptops, tablets, smartphones, and educational software. Technology is seen as a tool to enhance learning, engage students, and prepare them for the digital world.Teacher's role: In the school of the industrial age, the teacher was the primary source of knowledge and authority. The teacher lectured and imparted information to the students. The students were expected to listen, memorize, and regurgitate the information. In contrast, the school of the digital age emphasizes the teacher's role as a facilitator, coach, and guide. The teacher creates a supportive and engaging learning environment that allows students to explore, experiment, and discover knowledge.Learning outcomes: The school of the industrial age focused on preparing students for factory work and a standardized society. The emphasis was on discipline, obedience, and conformity. In contrast, the school of the digital age aims to prepare students for a complex, diverse, and rapidly changing world. The emphasis is on creativity, innovation, and adaptability. The goal is to develop lifelong learners who can learn, unlearn, and relearn.In summary, The school of the digital age places greater emphasis on digital literacy, critical thinking, collaboration, and creativity, and seeks to prepare students for a rapidly changing world.

//Testing for min
cout << "The smallest number in intList: "

Answers
Answer:
Here is the updated code for the `arrayListType` class with the abstract function `min` added:
```cpp
class arrayListType
{
public:
virtual int min() const = 0;
//other member functions
};
```
And here is the implementation of the `min` function in the `unorderedArrayListType` class:
```cpp
class unorderedArrayListType : public arrayListType
{
public:
int min() const override
{
int minVal = list[0];
for (int i = 1; i < length; i++) {
if (list[i] < minVal) {
minVal = list[i];
}
}
return minVal;
}
//other member functions
};
```
And here's an example program that uses the `min` function:
```cpp
#include <iostream>
#include "arrayListType.h"
#include "unorderedArrayListType.h"
using namespace std;
int main()
{
unorderedArrayListType intList(25);
int number;
cout << "Enter 8 integers: ";
for(int i = 0; i < 8; i++)
{
cin >> number;
intList.insertEnd(number);
}
cout << endl;
intList.print();
cout << endl;
cout << "The smallest number in intList: " << intList.min() << endl;
return 0;
}
```
Assuming that the `arrayListType` and `unorderedArrayListType` header and implementation files are properly included and compiled, this program should output the smallest number in the list.

What type of projects can I find in Workana?
A) Free projects
B) Paid projects in which I can charge per hour worked or by finished project
C) Projects paid by commission
D) Projects in which I can partner with other users and share profits
E) All of the above
Answers
Answer:
E
Explanation:
When you are looking for projects at Workana or post a project, you can work o post a project for a fixed price or hourly.
Let's see the differences
Fixed Price:
Fixed prices are the projects that are well defined with the reach and job structure and the payment will be realized once at the end of the job. The customer and professional agreed price before starting working on the project. It's important to measure the specific goals for both sides. As soon as the job goes on, some deliverables will define the progress of the job. It's crucial to keep clear the reach, time and deliverables before starting work on the project. In this way, you can avoid miscommunication.
On the other hand, if it is not clear what is expected on the project that you applying for, some changes are suddenly expected on the project that you are already working on, or even if you must dedicate a large part of your week/month in this project, then it is recommended that you be hired in a more flexible way.
Projects by Hour
In these cases above the best choice are jobs by hour. Both customer and professional agreed on a price per hour and starts working on the project reporting the hours that were worked on through Workana.
Customers can accept or reject the report and have perfect control over the job that is being realized. Also, it can limit the authorized hours that a professional can work on his project. Doesn't matter if the job is a fixed price or per hour, be sure that all is well accorded and the objectives are clear to achieve success for both sides.
As both agree before starting, less misunderstanding they will have.
Remember that fixed-price projects always have Workana's guarantee.
And the guarantee on projects by the hour is valid only if the hours are registered by Workana Time Report.
The money will be released only when the project is totally finished according to the initial deal.

Describe the discretionary power of police
Answers
Police officers are trained to use their discretion in a way that is fair, impartial, and consistent with the law. They are expected to exercise their power in a way that promotes public safety and protects the rights of individuals. However, discretionary power can also be abused, leading to unfair treatment or discrimination based on factors such as race, ethnicity, or socio-economic status.
Police officers are held accountable for their use of discretionary power through internal review processes and external oversight by independent agencies. In some cases, excessive or inappropriate use of discretionary power can lead to disciplinary action, legal consequences, or civil suits against the police department.
Overall, the discretionary power of police is an important aspect of their role in maintaining law and order. However, it is important to ensure that this power is used in a way that is fair, transparent, and accountable, and that it promotes trust and confidence in the police force among all members of the community.

In this program, we first read the first number using the DOS interrupt `INT 21h` with function `AH=1`. We subtract the character code for '0' to convert it to a numeric value and store it in the `BL` register. We then read the second number and add it to the first number in `BL`. We read the third number and subtract it from the sum of the first two numbers in `BL`. We then compare the result to 0 and 9 to ensure that it is not less than 0 or greater than 9, respectively. If it is less than 0, we set it to 0. If it is greater than 9, we set it to 9. We then print the final result using the DOS interrupt `INT 21h` with function `AH=2`. Finally, we exit the program using the DOS interrupt `INT 21h` with function `AH=4Ch`.

The first asks you to think of a number between 1 and 10. The second displays a randomly generated number; the user can see whether his or her guess was accurate. (In future chapters, you will improve this game so that the user can enter a guess and the program can determine whether the user was correct. If you wish, you also can tell the user how far off the guess was, whether the guess was high or low, and provide a specific number of repeat attempts.) Save the file as RandomGuess.java

JOptionPane.showMessageDialog(null, "Your guess was " + guess + "\nThe number was " + random + "\n" + (guess == random ? "You guessed it!" : "Better luck next time."));

Explanation:
This program prompts the user to think of a number between 1 and 10, then generates a random number in the same range and displays it in a dialog box along with the user's guess. If the guess matches the random number, the program displays a "You guessed it!" message; otherwise, it displays a "Better luck next time" message.
