Answer:
C. RepName is an alternate candidate key
Explanation:
The explanation is attached in a document.
Answer:
public class newass {
/*
Write a method, makeSubjectLine, that gets a String argument and returns the same String but with "Subject: " in front
of it. So if the argument is "Are you going to the show?" the method returns "Subject: Are you going to the show?".
*/
public static void main(String[] args) {
System.out.println(makeSubjectLine("Are you going to the show?"));
}
public static String makeSubjectLine(String subj){
return "Subject: "+subj;
}
}

The solution in Java Programming Language
<span>This problem is an
example of ratio and proportion. You are given 6y:9y. You are required to
convert this into its simplest form. The 6y:9y is also equivalent to 6y/9y. The
‘y’ variable can be eliminated since it has the same exponent and base. You are
left with 6/9. The common factor for 6 and 9 is 3 so divide each number by 3. So
6/3 is 2 and 9/3 is 3. You get 2/3. This is its simplest form.</span>
Answer:
D) Static method
Explanation:
A static method is a method that is created only for the class and not it's instance variables or objects. Such methods can only be accessed by calling them through the class's name because they are not available to any class instance. A static method is created by prefixing the method's name with the keyword static.
A static method cannot be overridden or changed. You create a static method for a block of code that is not dependent on instance creation and that can easily be shared by all instances or objects.
Answer:
it is assumed that only A and B can be used, for the reason that in binary there are only two Variables.
Explanation:
In number bases digits include are from 0 to base-1, e.g. in base two (binary), we have from 0 to 2-1. that means we only have 0 and 1. there's no other digit or variable allowed apart from 0 and 1 in base 2 (binary). so in the binary message sending device, a message can only be sent as a sequence of states (A and B).
