the grade point average collected from a random sample of 150 students. assume that the population standard deviation is 0.78. find the margin of error if c = 0.98.

Answer:

public class Person {

   String name;

   int age;

   String phoneNumber;

   public Person(String name, int age, String phoneNumber){

          this.name = name;

          this.age = age;

          this.phoneNumber = phoneNumber;

   }

}

Explanation:

The code above is written in Java.

The following should be noted;

(i) To define a class, we begin with the keywords:

public class

This is then followed by the name of the class. In this case, the name is Person. Therefore, we have.

public class Person

(ii) The content of the class definition is contained within the block specified by the curly bracket.

(iii) The class contains instance variables name, age and phoneNumber which are properties specified by the Person class.

The name and phoneNumber are of type String. The age is of type int. We therefore have;

String name;

int age;

String phoneNumber;

(iv) A constructor which initializes the instance variables is also added. The constructor takes in three parameters which are used to respectively initialize the instance variables name, age and phoneNumber.

We therefore have;

public Person(String name, int age, String phoneNumber){

          this.name = name;

          this.age = age;

          this.phoneNumber = phoneNumber;

   }

(v) Notice also that a constructor has the same name as the name of the class. In this case, the constructor's name is Person.

Answer:

The class and constructor in C++ is as follows:

class Person {

 public:

   string name;     int age;     int phone;

   Person (string x, int y) {  

     name = x;       age = y;  

   }

};

Explanation:

This defines the class

class Person {

The specifies the access specifier

 public:

This declares the attributes; name, age and phone number

   string name;      int age;      int phone;

This defines the constructor for the name and age

   Person (string x, int y) {  

This gets the name and age into the constructor

     name = x;       age = y;  

   }

};

Answer:

I think the third one (or the one with monkeys).

Explanation:

2+2 does not equal 5, so the if then statement is void because both parts are wrong.

1+1 does not equal 3 even if 2+3 =5, so it is not the second answer.

3+1 does not equal 3, but monkeys do fly and it is an or option, so when one of them is correct in an or, it is correct.

Answer:

d. The system of water spray pipes did not have sufficient water supply

Explanation:

The Union Carbide India Ltd. was chemical factory situated at Bhopal that produces various pesticides, batteries, plastics, welding equipment, etc. The plant in Bhopal produces pesticides. In the year 1984, on the night of 2nd December, a devastating disaster occurred on the Bhopal plant which killed millions of people due to the leakage of the poisonous, methyl isocyanate. This disaster is known as Bhopal Gas tragedy.

Soon after the gas pipe exploded, the fire brigade started spraying water into the air to [tex]\text{knock down}[/tex] the cloud of the gases in the air but there was not sufficient amount of water in the water sprays and so it was not effective.

Thus the correct answer is option (d).

The file named as A10.java has been attached to this response. It contains the source code for the exercises. The source code contains comments explaining important parts of the code.

A few things to note;

i. To add an item to an arraylist, the add() method is used. For example to add an integer 7 to the arraylist named intList, simply write;

intList.add(7);

ii. To add an item to a hashmap, the put() method is used. The put method receives two parameters which are the key and value respectively. The key is a form of identifier used to store or retrieve a particular value in a hashmap. To store an integer 8 with a key of 5 in a hashmap named intMap, for example, simply write;

intMap.put(5,8);

Answer: Pulldown menus

Explanation:

Pulldown menus refer to the graphical control element, that is identical to a list box, which enables user to be bake to select one value from a list.

They're regarded as the menu of options that will appear when an item is selected with a mouse. In this case, the item that the user selected will show at the top of the display screen, while the menu appears will show below it.

Therefore, Alex should use the pulldown menus to hide the long list of hypertext links so that it appears only in response to a tap of a major heading in the navigation list.

Just input the codes in the notepad

Answer:

a) 20 users

b) 0.1  or 1/10

c) P ( X = n )   =   [tex]^{120}C_{n} ( 0.10 )^n (0.9)^{120-n}[/tex]

d) 0.008

Explanation:

Given data:

Link shared by users = 3 Mbps

each user requires ; 150 kbps

percentage transmitted by each user = 10%

a) Determine the number of users can be supported

number of users = 3 Mbps / 150 kbps = 3000 / 150 = 20 users

b) P( user is transmitting )

given that percentage transmitted by each user = 10%

since packet switching is used ; P ( user is transmitting ) = 10% = 0.1

c) P ( n users are transmitting simultaneously )

let the number of users ( i.e. N ) = 120

number transmitting = n

P ( user is transmitting ) = 0.10

using Binomial distribution

P ( X = n ) = [tex]^{N}[/tex]Cₙ ( P )ⁿ ( 1 - P )^[tex]^{N-n}[/tex]

                = [tex]^{120}C_{n} ( 0.10 )^n (0.9)^{120-n}[/tex]

d) P( X ≥ 21 transmitting simultaneously )

P ( X = n ) = [tex]^{120}C_{n} ( 0.10 )^n (0.9)^{120-n}[/tex]

Therefore ; P( X ≥ 21 ) = 1 - P( X ≤ 20 )

                                   = 1 - BINOMDIST(20,120,0.1,1)  ( excel function )

∴ P( X ≥ 21 ) = 1 - 0.992059 ≈ 0.008

Answer:

Here the answer is given as follows,

Explanation:  

The real-life situation of a deadlock resolution where a role is played by the victim is given as follows:  

Example: An example of such a situation are often a one-way lane where the flow of traffic is merely in a method. Thus, on just one occasion, the flow of traffic can enter one direction only. Each entrance/exit gate is often considered a resource. during this case, if two cars are coming from both the entrances and that they are often considered as two tasks, then one among the cars must copy or we will say hand over its resource in order that the opposite car gets the prospect to first cross the lane or we will say the opposite task gets executed.  

 a)  Victim: The steps which describe how a victim is chosen are given as follows :  

   The task which is terminated so as to interrupt things of deadlock is taken into account because of the victim.

There are often a variety of job pools that will be under a deadlock situation and therefore the victim is usually a low-priority task in order that the performance isn't affected that much and termination of this task doesn't cause any effect on the opposite jobs.

the main positive effect of selecting and terminating a victim is that things of deadlock are resolved and every one of the tasks can execute now.

The negative effect is that the task that's chosen because the victim is terminated and is executed at the previous. This whole process for choosing a victim then terminating it then restarting it again may consume some longer also.

b)  An easy deadlock priority is often set. this suggests that the victim’s task or the task is often terminated so as to interrupt the deadlock and other jobs can finish executing. After this, the task which is terminated are often later restarted and every one of the tasks can then execute without a deadlock.

 c) When employment gets terminated, the knowledge associated with it's stored. Are often This is often done in order that the work can be restarted again and therefore the information in it's not lost. Since the progress of the victim is stopped. Thus, the sole thanks to complete the victim’s task would be to start out it again. But before restarting the task, this must be considered that the victim’s task doesn't cause any deadlock within the system.

[tex]\boxed{ File }[/tex] is a collection of information stored under a single name.

[tex]\bold{ \green{ \star{ \orange{Mystique35}}}}⋆[/tex]

Answer:

Explanation:A collection of information that is stored on a computer under a single name, for example a text document, a picture, or a program. The association between a file and the program that created the file. Displays the contents of the current folder or library.

Answer:

The program is as follows:

prod = 1

isum = 0

for i in range(4):

   num = float(input())

   prod*=num

   isum+=num

avg = isum/4

print('{:.0f}'.format(prod))

print('{:.3f}'.format(avg))  

Explanation:

This initializes the product to 1

prod = 1

..... and sum to 0

isum = 0

The following iteration is repeated 4 times

for i in range(4):

Get input for each number

   num = float(input())

Calculate the product

   prod*=num

Add up the numbers

   isum+=num

This calculates the average

avg = isum/4

Print the products

print('{:.0f}'.format(prod))

Print the average

print('{:.3f}'.format(avg))

Answer:

travel

Explanation:

One real world example of a singly-linked list would be travel. Imagine that you want to take a trip to your nearest neighbor state. To do so you would need to take a 2 buses and a train, but you can't just take any or in any order you wish. You first need to take the first bus at your current location, get off at the train station, take that train to the final stop, get off and take the bus to the final destination. Meaning there is a sequence of connected events that you must follow in order to get to your destination and the same opposite sequence of events to get back. This is exactly like a singly-linked list.

Answer:

The object creation should be Arcade myArc("Games Ablaze",5);

Explanation:

Why does the program generate an error?

The class definition is correctly defined and implemented;

The methods in the class are also correctly defined and implemented.

The error in the program is from the main method i.e.

int main() {  

       Arcade myArc('ames Ablaze, 5);  

       myArc.Print();  

   }

In the class definition;

Variable name was declared as string and variable rating was declared as integer

This means that, a string variable or value must be passed to name and an integer value or variable to rating.

Having said that:

Arcade myArc(Games Ablaze, 5); passes Games Ablaze as a variable to th function.

Game Ablaze is an incorrect string declaration in C++ because of the space in between Game and Ablaze

Also, no value has been assigned to the variable (assume the variable definition is correct).

This will definitely raise an error.

To correct the error, rewrite the object creation as:

Arcade myArc("Games Ablaze",5); where "Game Ablaze" is passed as string
