A city planner is using simulation software to study crowd flow out of a large arena after an event has ended. The arena is loca

ted in an urban city. Which of the following best describes a limitation of using a simulation for this purpose?
a) The model used by the simulation software cannot be modified once the simulation has been used.
b) The model used by the simulation software often omits details so that it is easier to implement.
c) Running a simulation requires more time to generate data from trials than observing the crowd exiting the arena at various events.

Answer:

d)

Explanation:

The main limitation of simulations is that running a simulation requires a large number of observations to be collected before it can be used to explore a problem. In a real life situation there are thousands of variables to take into consideration which can drastically affect the way that the situation unfolds at any given time. Therefore, in order to replicate/simulate such a scenario all of these variables need to be taken into consideration. This data can take a large amount of time to observe and collect in order to implement into the simulation so that it provides an accurate depiction of the problem.

VLD [36.1K]

Answer:

The first thing that the browser checks is the cache for the DNS record to find the corresponding IP address.

Explanation:

After the technician sets up the internal DNS server for his local network, the first thing that is checked when he types a website into the url of a browser is the cache to look for corresponding IP addresses.

DNS which means Domain Name System is a database that maintains the website name (URL) and the IP address that it is linked to. There is a unique IP address for every URL (universal resource locator).

Internal DNS servers store names and IP addresses for internal or private servers

Show how to define a view tot_credits (year, num_credits), giving the total number of credits taken by students in each year
andreev551 [17]

Hi! I'm a Digital Marketer Intern at hotels.ng and I have a moderate knowledge on programming.

First, your  question is not very explanatory. The term "view" is often used in back-end web development. A view is simply a Python function that takes a Web request and returns a Web response.

But I'm not sure this is what you want, so I'll just go ahead and write a python function involving class to return the total number of credits taken by a student.

I'll answer this question using Python.

class student(object):  

    credits = None

    year = None

    def num_credits(self):


       #get credit value

       self.credits = input("Enter the total number of credits: "  )


       pass

    def getYear(self):

        self.year = input("Enter current year: ")

        pass

    def tot_credits(self):

          TotalCredits = tempTotalCredits + self.num_credits

           print "Your  total credits are :"+" "+str(TotalCredits)

Explanation:

import java.awt.event.*;  

import java.awt.geom.Area;

import javax.swing.*;

class MVCTester implements ActionListener{

JButton b; //button

JTextField t1; //textfiled

JTextArea area; //text area

MVCTester(){

JFrame f=new JFrame("Button Example");

//button

b=new JButton("add");  

b.setBounds(0,0,125,27);  

f.add(b);  

b.addActionListener(this);  

//textfiled

t1=new JTextField();  

t1.setBounds(0,161,125,24);  

f.add(t1);

//textarea

area=new JTextArea();  

area.setBounds(0,28,123,130);  

f.add(area);

"at"Override

public void actionPerformed(ActionEvent arg0) {

area.setText(area.getText()+t1.getText()+"\n");

t1.setText("");

}

}

public class Modal{

public static void main(String[] args) {

Which two factors most influenced the growth of the Internet during the 1970s?
eduard

Answer:

The answer is "increase in the power of public universities and increased appreciation for a liberal arts education". DARPA and Russia had nothing to do with this. Yes, the computer hardware improvement led to a growth, but National Science Foundation funding in 1981, and hence this is also not an option. And electrical power supply had nothing to do with this. Hence, the above answer. as the concept of the internet is based on liberal arts of education, to impart practical and intellectual skillsets, and hence to grow the social responsibility among the citizens of the whole world. Also, the power of public universities had a big role to play definitely, and this was confirmed from Pentagon as well then when the question was raised, is this due to the risk of a nuclear attack.

Many people think that the main reason was the nuclear attack threat, but that was not an issue definitely. Actually this was the time of liberalization, and the power of the public universities was increased. Hence, they got the chance to share the information of various sorts with the people, and in the process internet started expanding.

Explanation:

The answer is self explanatory.
