The answer would be <u><em>a site associated with a local university! </em></u>

<em>".edu"</em> : The information within belongs to a place of education, such as a school or university. Nonprofit schools, such as most state colleges and universities, are mostly unbiased in their approach to what is housed within their links. These are generally good sites to use in research.

<em>Hope this helps!</em>

Explain how AI smartphone software in the rental car can be a threat to privacy.
Elan Coil [88]

Answer:

The real reason why AI smartphone software in the rental car is threat to privacy is that the data transmitted can actually be exposed to security breaches in the software and so if that happens, the car is no longer under the control of the user.

Hope this helps!

Fill in this function that takes three parameters, two Strings and an int. 4- // Write some test function calls here! The String
zimovet [89]

Answer:

The function in Java is as follows:

public static void printMessage(String lineOne, String lineTwo, int lines){

       for(int i = 1;i<=lines;i++){

           if(i%2 == 1){

               System.out.println(lineOne);

           }

           else{

               System.out.println(lineTwo);

           }

       }

   }

Explanation:

This defines the function

public static void printMessage(String lineOne, String lineTwo, int lines){

This iterates through the number of lines

       for(int i = 1;i<=lines;i++){

String lineOne is printed on odd lines i.e. 1,3,5....

      if(i%2 == 1){

               System.out.println(lineOne);

           }

String lineTwo is printed on even lines i.e. 2,4,6....

           else{

               System.out.println(lineTwo);

           }

       }

   }

To call the function from main, use:

printMessage("Hi", "Karel", 5);

In this task, you will perform normalization on a crude table so that it could be stored as a relational database.
ryzh [129]

Answer:

Check the explanation

Explanation:

(1.) The functional dependencies based on assumptions are as follows:-

Trip determines which staff was there in the trip, the car used for the trip, the quantity of fuel used in the trip, the fill up time and the total paid of the trip.

Service station refers to its address

Car details consist of the details of license plate, odometer reading and the fuel type used in the car

fuel type and the fill up time will help to determine the cost of the fuel at that time

cost of the fuel and the quantity of fuel used will determine the total paid

From the above assumptions the functional dependencies are as follows:-

Trip ID -> Staff Name, Car Details, Service Station, Quantity, Fill Up Time, Total Paid

Service Station -> Station Address,

Car Details -> License Plate, Odometer reading, Fuel Type

Fuel Type, Fill up Time -> Cost per litre

Cost per Litre, Quantity -> Total Paid

(2.) Initially the relation is as follows:-

R (Trip ID, Staff Name, Car Details, License Plate, Odometer Reading, Service Station, Station Address, Fill up Time, Fuel type, Quantity, Cost per Litre, Total Paid)

For 1 NF there should not be composite attributes,in the above relation Staff Name and Station Address are composite attributes therefore it will be decomposed as follows:-

R (Trip ID, Staff First Name,Staff Last Name, Car Details, License Plate, Odometer Reading, Service Station, Street, City, State, Zip Code, Fill up Time, Fuel type, Quantity, Cost per Litre, Total Paid)

For 2 NF there should not be partial dependency that is non prime attribute should not dependent upon any 1 prime attribute of candidate key, since in the given relation there is only 1 candidate key which is only Trip ID, therefore the relation is already in 2 NF.

For 3 NF there should not be transitive dependency that is non prime attribute should not dependent upon the other non prime attribute, if it is present then the relation will be decomposed into sub relations, the given relation is not in 3 NF therefore it will be decomposed as follows:-

R1 (Trip ID, Staff First Name, Staff Last Name, Car Details, Service Station, Quantity, Fill up time, Total paid)

R2 (Service Station, Street, City, State, Zip Code)

R3 (Car Details, License Plate, Odometer reading, Fuel Type)

R4 (Fuel Type, Fill up Time, Cost per litre)

R5 (Cost per Litre, Quantity, Total Paid)

(3.) After the 3 NF we add the primary and foreign key constraints as follows:-

R1 (Trip ID, Staff First Name, Staff Last Name, Car Details, Service Station, Quantity, Fill up time, Total paid)

R2 (Service Station, Street, City, State, Zip Code)

R3 (Car Details, License Plate, Odometer reading, Fuel Type)

R4 (Fuel Type, Fill up Time, Cost per litre)

R5 (Cost per Litre, Quantity, Total Paid)

In the above relational schema the primary keys are represented with bold and foreign keys by italic

(4.) The ER diagram of the above relational schema using crow's foot notation are as shown in the attached image below:-
