Answer: C. The ideas behind it are relatively new.

Explanation:

The ideas behind data mining are based on the principle of identifying patterns in large sets of data.

This idea is not new because some other statistical principles like the Bayem's theorem of the 1700's and the regression analysis of the 1800's were based on this idea of identifying patterns in large sets of data.

The Bayem's theorem was founded by Reverend Thomas Bayem and it was based on the principle that the probability that an event will occur is dependent on former conditions that made the event occur.

The regression analysis measures the ways in which a dependent and independent variable are related.

Write a method called fact that recursively calculates the factorial value of its single int parameter. The value returned by fa
andrey2020 [161]

Answer:

The program to this question can be given as follows:

Program:

//class

public class factorial //defining class

{

//method fact

public static long fact(int x1) //defining method fact

{

//conditional statement

if (x1 <= 1) //if block checks parameter value less then equal to 1

{

return 1; //return value

}

else //else part

{

return (fact(x1 - 1) * (long) x1); //return factors using recursive function

}

}

//method main

public static void main(String[] args) //defining main method

{

long data=fact(5);//defining variable that holds function value

System.out.println("Factorial is: "+data); //print value

}

}

Output:

Factorial is: 120

Explanation:

In the above java program, a class is "factorial" is defined, inside the class, a static method "fact" is declared, that accepts an integer parameter that is "x1" and returns a long value, inside this method a conditional statement is used.

  • If the block it checks parameter value is less then equal to 1, if this condition is true, it will return 1 when this condition is not true. It will go in else part.
  • In else part, it uses a recursive function to calculate factorial of a number and return its value.
  • Then the main method is defined, inside this method a long variable "data" is defined, that call and holds fact function return value, and in the next line, the print function is used to print the data variable value.

Cardinality ratios often dictate the detailed design of a database. The cardinality ratio depends on the real-world meaning of t
Otrada [13]

Solution :

ENTITY 1               CARDINALITY RATIO                                     ENTITY 2

1. Student                        1 to many                                     Social security card

                      A student may have more than one          

                     social security card (legally with the

                      same unique social security number),

                     and every social security number belongs

                   to a unique.

2. Student                   Many to Many                                    Teacher

                    Generally students are taught by many

                    teachers and a teacher teaches many students.

3.ClassRoom               Many to Many                                   Wall

                      Do not forget that the wall is usually

                      shared by adjacent rooms.

4. Country                 1 to 1                                             Current President

                       Assuming a normal country under normal

                       circumstances having one president at a

                      time.

5. Course               Many to Many                               TextBook

                        A course may have many textbooks and

                       text book may be prescribed for different

                      courses.

6. Item                             Many to Many                           Order

                        Assuming the same item can appear

                         in different orders.

7. Student                       Many to Many                          Class

                        One student may take several classes.

                        Every class usually has several students.

8. Class                                 Many to 1                             Instructor

                       Assuming that every class has a unique

                        instructor. In case instructors were allowed

                        to team teach, this will be many-many.

9. Instructor                  1 to 1                                             Office

                       Assuming every instructor has only one

                      office and it is not shared. In case of offices

                     shared by 2 instructors, the relationship

                    will be 2-1. Conversely, if any instructor has a joint

                    appointment and offices in both departments,

                    then the relationship will be 1-2. In a very general

                  case, it may be many-many.

10. E-bay Auction item             1-Many                           E-bay bid

                        1 item has many bids and a bid is unique

                        to an item.
