Suppose we wanted to make change for purchases and wanted to use the least number of coins possible. Here is a greedy algorithm: for the change amount due, we always use the largest-face-value coin first. Assume we have only coins of quarters ($.25), twenties ($.20), and pennies ($.01). Assume the change is $.40: a. what would be the coins and their numbers obtained by the greedy algorithm above

Answer:

Lack of global control.

Explanation:

An operating system is a system software pre-installed on a computing device to manage or control software application, computer hardware and user processes.

This ultimately implies that, an operating system acts as an interface or intermediary between the computer end user and the hardware portion of the computer system (computer hardware) in the processing and execution of instructions.

Some examples of an operating system on computers are QNX, Linux, OpenVMS, MacOS, Microsoft windows, IBM, Solaris, VM etc.

There are different types of operating systems (OS) used for specific purposes and these are;

1. Batch Operating System.

2. Multitasking/Time Sharing OS.

3. Multiprocessing OS.

4. Single User OS.

5. Mobile OS.

6. Real Time OS .

7. Distributed OS.

8. Network OS.

A network operating system (NOS) can be defined as specialized computer operating system that are designed primarily for use on network devices such as routers, switches, workstations, which are mainly connected to a local area network.

Generally, the biggest limitation of a network operating system (NOS) is lack of global in terms of memory, process, device, and file management.

Answer:

install and configure on the server DHCP (Dynamic Host Configuration Protocol)

Explanation:

In this scenario, you should install and configure on the server DHCP (Dynamic Host Configuration Protocol), this protocol automatically assigns each individual PC a unique IP address and DNS server information. This protocol has various configuration options such as being able to set a range for the IP addresses so that they can be used by different devices in the system. It also allows you to directly set the subnet and passage gateway so that all of the workstations can quickly communicate with one another and quickly be targeted by the administration.

Answer: A. Cell

Explanation:

A cell is the point on the worksheet that results from the intersection of a column and a row.

This is why cells can be identified by the column and row that they are the result of. For instance, a cell can be called "A12" which is also known as its "address". This means that it is a result of the intersection of "Column A" and "Row 12".

Answer:

Explanation:

Answer:

The function is as follows:

def list_to_string(input_list,separator):

   output = ""

   for inp in input_list:

       output+=inp+separator

   output = output[:-1]

   return output

Explanation:

Given

See attachment for instruction

Required

A function to convert list to string

This defines the string

def list_to_string(input_list,separator):

This initializes the output to an empty string

   output = ""

This iterates through the input list

   for inp in input_list:

This concatenates every string in the list including the separator

       output+=inp+separator

This removes the last character of the string

   output = output[:-1]

This returns the output string

   return output

Answer:

The function is as follows:

def divisible_by(listi, n):

   mylist = []

   for i in listi:

       if i%n == 0:

           mylist.append(i)

   return mylist

   pass

Explanation:

This defines the function

def divisible_by(listi, n):

This creates an empty list

   mylist = []

This iterates through the list

   for i in listi:

This checks if the elements of the list is divisible by n

       if i%n == 0:

If yes, the number is appended to the list

           mylist.append(i)

This returns the list

   return mylist

   pass

Answer:

Explanation:

Based on the information provided in the question, the best rules that the technician should add to the firewall would be the following

Permit 10.10.10.0/24 0.0.0.0 -p tcp --dport 443

Permit 10.10.10.0/24 192.168.1.15/24 -p udp --dport 53

This is because port 443 is used for "Secure webs services" while UDP port 53 is used for queries and domain name resolution. Both of which are the main configurations that the security technician needs to obtain.

The following recursive method is written in Java. It creates a simulation of the towers of Hanoi and outputs every step-by-step instruction on how to solve it. The output for the code can be seen in the attached picture below.

class Brainly {

   public static String hanoi(int numOfDisks, int startPeg, int endPeg) {

       int helpPeg;

       String sol1, sol2, MyStep, mysol;   // Contains moves

       if (numOfDisks == 1) {

           return "Move from " + startPeg + " to " + endPeg + "\n";

       } else {

           helpPeg = 6 - startPeg - endPeg;    // Because startPeg + helpPeg + endPeg = 6

           sol1 = hanoi(numOfDisks - 1, startPeg, helpPeg);

           MyStep = "Move from " + startPeg + " to " + endPeg + "\n";

           sol2 = hanoi(numOfDisks - 1, helpPeg, endPeg);

           mysol = sol1 + MyStep + sol2;     // + = String concatenation !

           return mysol;

       }

   }

   public static void main(String[] args) {

      String output = hanoi(3, 1, 3);

       System.out.println(output);

The terms data and information can mean different things in different contexts, but the main differences between them are: Data is a collection of facts. Information is how you understand those facts in context. Data is unorganized, while information is structured or organized.

Answer:

Explanation:

The Rectangle and Point class is not provided in this question but was found online. Using that code as guidance I created the following method named contains. This method takes in a Point object and checks to see if the x-axis point is inside the parameters of the Rectangle class and then checks the same for the y-axis. If it is inside the Rectangle then the method returns true otherwise it returns false.

def contains(self, point):

       return self.width > point.x >= self.corner.x and self.height > point.y >= self.corner.y

Answer: C

Explanation:

Answer:

The modified SQL code is as follows:

SELECT Title, ReleaseDate FROM movie WHERE Rating = "PG-13" and ReleaseDate >  '2008-02-01'

Explanation:

The syntax of an SQL select statement is:

SELECT c1, c2, c...n FROM table WHERE condition-1, AND/OR condition-n

In this query, we are to select only the title and the release date.

So, we have:

SELECT Title, ReleaseDate

The table name is Movie.

So, we have:

SELECT Title, ReleaseDate FROM movie

And the condition for selection is that:

Ratings must be PG-13

And the date must be later than February 1, 2008

This implies that:

Rating = "PG-13"

ReleaseDate >  '2008-02-01'

So, the complete query is:

SELECT Title, ReleaseDate FROM movie WHERE Rating = "PG-13" and ReleaseDate >  '2008-02-01'
