Answer:
Explanation:
The code provided is written in Java. The statement is provided right under the /*Type your code here*/. In Java, in order to case one primitive to another you simply need to type the primitive type that you are trying to cast too before the variable and within parenthesis. The output of the new code can be seen in the attached image below.
class LabProgram {
public static int convert(double d){
/* Type your code here */
return (int) d;
}
public static void main(String[] args) {
System.out.println(convert(19.9));
System.out.println(convert(3.1));
}
}
Answer:
Increasing
Explanation:
Generally in economics, opportunity cost is the benefit that a person, a business, or an investor forgo or missed when he chooses one alternative instead of the other.
Under production, opportunity cost occurs when a producer sacrifice the production of one for the production of another good. Using good X and Y as examples, opportunity cost is measured by the number of units of good Y that the producer gives up in order to produce one or more units of good X.
In the question, the two products used are computers and DVD. The -15, -18 and -20 implies that producing an extra unit of computer by moving from point A to point B, point B to C, and point C to D, 15, 18 and 20 units of DVD respectively have to be given up.
Since 20 is greater than 18 and 18 is also greater than 15, it therefore implies as we produce more computers, the opportunity cost, which are the number of DVDs given up at each point, are increasing.
I wish you the best.
