Fatima has 3 packs of batteries. Each pack contains 4 batteries. She gives her brother 8 batteries to put in his toy robot. Let b represent the number of batteries Fatima has left. Which equation could be used to find the value of b?

Answer: See explanation

Explanation:

Let b represent the number of batteries Fatima has left.

The equation that can be used to find the value of b goes thus:

(3 × 4) = b + 8

12 = b + 8

b = 12 - 8

Therefore, based on the above equation, the number of batteries that Fatima has left will be 4.

You have created a group policy that prevents users in the accounting department from accessing records in a database that has confidential information. The group policy is configured to disable the search function for all users in the Accounting OU no matter which workstation is being used. After you configure and test the policy, you learn that several people in the Accounting OU have valid reasons for using the search function. These users are part of a security group named Managers. What can you do to prevent the Group Policy object (GPO) that you have configured from applying to members of the Managers group

does anyone know what's wrong with this code

An array is mirrored if one half of the array is a reflection of the other. For example, these are mirrored arrays:

int[] a = {5, 4, 3, 4, 5};
int[] b = {9, 2, 2, 9};

The intent of the following methods is to determine whether an array is mirrored or not.

public boolean isMirrored(int[] array) {
// Add code here
}

private boolean isMirrored(int[] array, int leftIndex, int rightIndex) {
if (leftIndex > rightIndex) return true;
if (array[leftIndex] != array[rightIndex]) return false;
return isMirrored(array, leftIndex + 1, rightIndex - 1);
}

Which of the following statements, when inserted at the comment, “Add code here”, would complete the first isMirrored() method, call the second isMirrored() method, and produce the correct results?
A. return isMirrored(array)
B. return isMirrored(array, 0, 0)
C. return isMirrored(array, 0, array.length - 1);
D. return isMirrored(array, array[leftIndex], array[rightIndex]);


Which of the following is a method of the File class that can return an array of Files in a directory?
A. listFiles()
B. files()
C. getFiles()
D. directory()



Consider the following code.

public static int fileMethod(File dir) {
File[] files = dir.listFiles();
if (files == null) return 0;

int count = 0;
for (File f : files) {
if (f.isFile()) count++;
else count += fileMethod(f);
}
return count;
}

If dir represents a starting directory, which of the following statements best describes the operation of fileMethod()?
A. It counts and returns the number of files and directories inside dir and all subdirectories of dir.
B. It counts and returns the number of files, not counting directories, inside dir and all subdirectories of dir.
C. It counts and returns the number of files and directories only inside dir and inside only the first subdirectory found inside dir.
D. It counts and returns the number of files, not counting directories, but only those found inside dir and not its subdirectories.



Which of the following methods will correctly calculate the factorial of a positive number using iteration?
A.
public static long factorial(int n) {
if (n == 0) return 1;
else return n * factorial(n);
}
B.
public static long factorial(int n) {
if (n == 0) return 1;
else return n * factorial(n - 1);
}
C.
public static long factorial(int n) {
int product = n;
while (n > 0) {
n--;
product *= n;
}
return product;
}
D.
public static long factorial(int n) {
int product = n;
while (n > 1) {
n--;
product *= n;
}
return product;
}

Consider the following code.

public static String display(String s, int c) {
if (c == 0) return s;
else {
if (c > 3) return "-" + display(s, c - 1) + "-";
else return "=" + display(s, c - 1) + "=";
}
}

Which of the following methods most accurately reproduces the behavior of the display() method without using recursion?
A.
public static String d1(String s, int c) {
String retVal = "";
for (int i = 0; i < c; i++) {
if (i > 3) retVal += "-" + s + "-";
else retVal += "=" + s + "=";
}
return retVal;
}
B.
public static String d2(String s, int c) {
String retVal = "";
for (int i = 0; i < c - 3; i++) {
retVal += "-";
}
for (int i = 0; i < Math.min(3,c); i++) {
retVal += "=";
}
retVal += s;
for (int i = 0; i < Math.min(3,c); i++) {
retVal += "=";
}
for (int i = 0; i < c - 3; i++) {
retVal += "-";
}
return retVal;
}
C.
public static String d3(String s, int c) {
String retVal = "";
for (int j = 0; j < c - 3; j++) {
retVal += "-";
}
for (int j = 0; j < 3; j++) {
retVal += "=" + s + "=";
}
for (int j = 0; j < c - 3; j++) {
retVal += "-";
}
return retVal;
}
D.
public static String d4(String s, int c) {
String retVal = "";
for (int i = 0; i < c; i++) {
for (int j = 0; j < c - 3; j++) {
retVal += "-";
}
retVal += "===" + s + "===";
for (int j = 0; j < c - 3; j++) {
retVal += "-";
}
}
return retVal;
}

A small computer on a smart card has 4 page frames. At the first clock tick, the R bits are 1000 (page 0 is 1 and the rest are 0). At subsequent ticks, the values are 0110, 0101, 1010, 1101, 0101, 0011, and 1100. If the aging algorithm is used with a 16-bit counter, give the values of the four counters after the last tick. If page fault occurs, which page should be swapped out

You are planning a storage solution for a new Windows server. The server will be used for file and print services and as a database server. The new server has five hard disks, all with equal capacity. Your storage solution should meet the following requirements: System files should be on a volume separate from data files. All volumes should be protected so that the server can continue to run in the event of a failure of one of the disks. The data volume should be optimized for improved disk access times. You will use Windows Disk Management to create and manage the volumes. What should you do
