Answer:

The code will display the following on the screen:-

2

0

2

Explanation:

The output is like this because x{2} assigns the value 2 to the integer x.First the value of x is printed on the screen that is 2 and that newline is used to go to the next line.After that function is called doSomething with x passed as the argument. doSomething function assigns the value zero to the variable passed and prints it on the screen.So the next line is 0.Since x is passed by value so no changes will appear in the original argument.Hence the last line printed is 2.

SashulF [63]

Answer:

The code to this question can be defined as follows:

import java.util.*;//import package for user input

public class Main //defining a class

{

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

{

   int m1,m2,num,t,i;//defining integer variable

   Scanner incx = new Scanner(System.in);//creating Scanner class object

   m1 = incx.nextInt();//input value

   m2 = incx.nextInt();//input value  

   if (m1 > m2)//use if block to check m1 greater than m2  

   {//swapping value

       t = m1;//holding m1 value in t

       m1 = m2;//defining m1 that take m2

       m2 = t;//holding m2 value  

   }

   for (i = 2; i < 6; i++)//defining for loop  

   {

       num = incx.nextInt();//input value  

       if (num < m1) //defining if block to smallest value

       {

           m2 = m1;//holding m2 value in m1

           m1 = num;//holding num value in m1

       }  

       else if (num < m2)//defining if block to smallest value  

       {

           m2 = num;//holding num value in m2

       }

   }

       System.out.println(m1 + " " + m2);//print two smallest values

   }

}

Output:

5

10

5

3

21

2

2 3

Explanation:

In the above code, five integer variable "m1, m2, num, t, and i" is declared, in which it creates the scanner class object for inputs the value and use m1 and m2 use to the input value.

In the next step, if a block is used to swap the value and pass into the for loop that use if block to find the two smallest values and hold its value into the m1 and m2 and print its value.

Suppose that the format for license plates in a certain state is two letters followed by four numbers. (a) How many different pl
Ymorist [56]

Answer:

(a) 6,760,000 plates

(b) 3,407,040 plates

(c) 6,084,000 plates

Explanation:

The very first thing to note about this question is the number of characters involved in the license plate format (6 characters in this case; 2 letters and 4 numbers). The letters come first and then the numbers follow.

There are a total of 26 possible letters (A-Z) and 10 possible numbers (0 - 9) that can be chosen. We can then proceed to the first question;

(a) Here, the total number of possible plates is to be determined. This is done as follows:

Character 1 (Letter): There are 26 possible letters

Character 2 (Letter): There are 26 possible letters

Character 3 (number): There are 10 possible numbers

Character 4 (number): There are 10 possible numbers

Character 5 (number): There are 10 possible numbers

Character 6 (number): There are 10 possible numbers

So, total number of different plates will be obtained by multiplying all the possibilities: 26 × 26 × 10 × 10 × 10 × 10 = 6,760,000 plates

(b) This second part puts a constraint on the usage of the numbers, unlike the question (a), where there was no constraint at all.

Since there is no constraint on the letters, we can write that:

Character 1 (Letter): There are 26 possible letters

Character 2 (Letter): There are 26 possible letters

For the first number as well, we can write:

Character 3 (number): There are 10 possible numbers

However, for the remaining characters, the possibilities will continually reduce by a value of 1, since we can not use a number that has been used before. So,

Character 4 (number): There are 9 possible numbers

Character 5 (number): There are 8 possible numbers

Character 6 (number): There are 7 possible numbers

So, total number of different plates will be: 26 × 26 × 10 × 9 × 8 × 7 = 3,407,040 plates

(c) Here, repetitions are allowed as in questions (a), but there can not be four zeros. This implies that the maximum number of zeros in any plate will be three. Thus, there will be maximum possibilities on all characters until the last one which will be constrained.

Character 1 (Letter): There are 26 possible letters

Character 2 (Letter): There are 26 possible letters

Character 3 (number): There are 10 possible numbers

Character 4 (number): There are 10 possible numbers

Character 5 (number): There are 10 possible numbers

Character 6 (number): There are 9 possible numbers

Total number of plates will therefore be: 26 × 26 × 10 × 10 × 10 × 9 = 6,084,000 plates.

Grenstall Inc., a software development firm, has adopted a new job evaluation system in which managers are asked to objectively
rosijanka [135]

Answer:

Grenstall is most likely using the point system

Explanation:

The point system is a method of job evaluation system that involves measuring performance of workers in an organization and allocating points to identifiable factors such as skills, efforts, training, knowledge and experience based on its performance. It does not focus on entire job functions. The allocated points enables the organization to determine the compensation that is commensurate for a particular position.

Greenstall Inc uses the point system technique of job evaluation system for its managers as their jobs were broken down based on their skills, mental and physical efforts, training, and responsibility with points being allocated to each of these factors which are then summed up.
