Answer:

The correct answer is option b. "every action on a system is recorded in the kernel log".

Explanation:

Programming using linux kernel log levels is very helpful, because logs can inform about he state of daemon, or inform whether an error has occurred. However, is not true that every action on a system is recorded in the kernel log. Only certain information is found in the kernel log, which gives messages with different levels of severity, being the level 0 the most critical, and level 7 the less critical.

Answer:

import java.util.Scanner;

public class Main {

public static void main(String[] args) {

double cost = 0;

double priceF, priceS, priceT;

int nOne = 0, nTwo = 0, nThree = 0;

int fBurn, sBurn, tBurn;

int burnTime = 0;

isEnd = "n";

while (isEnd == "n"){

Scanner in = new Scanner(System.in);

int option = in.nextInt();

if (option == 1){

priceF = 2.50;

fBurn = 5;

System.out.print("Enter number of items: ");

nOne += in.nextInt();

burnTime += fBurn * nOne;

cost += priceF * nOne;

} else if (option== 2){

priceS = 3.75;

sBurn = 7;

System.out.print("Enter number of items: ");

nTwo += in.nextInt();

burnTime += sBurn * nTwo;

cost += priceS * nTwo;

} else if(option == 3){

priceT = 5.99;

tBurn = 12;

System.out.print("Enter number of items: ");

nThree += in.nextInt();

burnTime += tBurn * nThree ;

cost += priceT * nThree;

} else{

System.out.println("option must be between 1 and 3");

}

System.out.print("Do you want to end the order? y/n: ");

isEnd = in.nextLine();

}

System.out.println("Number of Type 1 candles bought : "+nOne);

System.out.println("Number of Type 2 candles bought : "+nTwo);

System.out.println("Number of Type 3 candles bought : "+nThree);

System.out.println("Total cost is : "+cost);

System.out.println("Total burn time is : "+burnTime);

double cpm = (burnTime * 60) / cost;

System.out.println("Cost per minute : "+cpm);

}

Explanation:

The Java program prompts the user to continuously choose from three options 1, 2 and 3. The prices, the burn time and the cost per minute burn of the total candles ordered are printed out.

Convert the following numbers from decimal to binary, assuming unsigned binary representation:________.

kumpel [21]

Answer:

Binary representations of following are:

A) 35 = 100011

B) 3 = 11

C) 27 = 11011

D) 16 = 10000

Explanation:

The method to generate the binary number from a decimal is :

Keep on dividing the number by 2 and keep on tracking the remainder

And the quotient is again divided and remainder is tracked so that the number is completely divided.

And then write the binary digits from bottom to top.

Please have a look at the method in below examples:

A) 35

$\begin{center}\begin{tabular}{ c c c }Number & Quotient & Remainder\\ 2 & 35 & 1 \\ 2 & 17 & 1 \\ 2 & 8 & 0 \\ 2 & 4 & 0 \\ 2 & 2 & 0 \\ 2 & 1 & 1\end{tabular}\end{center}$

Writing the remainder from bottom to top.

So, binary number is 100011

B) 3

$\begin{center}\begin{tabular}{ c c c }Number & Quotient & Remainder\\ 2 & 3 & 1 \\ 2 & 1 & 1 \\ \end{tabular}\end{center}$

Writing the remainder from bottom to top.

So, binary equivalent is 11.

C) 27

$\begin{center}\begin{tabular}{ c c c }Number & Quotient & Remainder\\ 2 & 27 & 1 \\ 2 & 13 & 1 \\ 2 & 6 & 0 \\ 2 & 3 & 1 \\ 2 & 1 & 1 \end{tabular}\end{center}$

Writing the remainder from bottom to top.

So, binary equivalent is 11011.

D) 16

$\begin{center}\begin{tabular}{ c c c }Number & Quotient & Remainder\\ 2 & 16 & 0 \\ 2 & 8 & 0 \\ 2 & 4 & 0 \\ 2 & 2 & 0 \\ 2 & 1 & 1 \\\end{tabular}\end{center}$

Writing the remainder from bottom to top.

So, binary equivalent is 10000.

Answers are:

Binary representations of following are:

A) 35 = 100011

B) 3 = 11

C) 27 = 11011

D) 16 = 10000
