Answer:
True
Explanation:
An analogue sensor has a bandwidth which extends from very low frequencies up to a maximum of 14.5 kHz. Using the Sampling Theorem, what is the minimum sampling rate (number of samples per second) required to convert the sensor signal into a digital representation?
If each sample is now quantised into 2048 levels, what will be the resulting transmitted bitrate in kbps?
Give your answer in scientific notation to 1 decimal place.
Hint: you firstly need to determine the number of bits per sample that produces 2048 quantisation levels
Answer:
3.2*10^5
Explanation:
By Nyquist's theorem we must have 2*14.5kHz=29kHz so 29,000 samples per second. 2048=2^11 so we have 11 bits per sample. Finally we have 29000*11 bits per second (bps) =319000=3.2 * 10^5
In this exercise we want to know how many bits will be transmitted between the two intelligences, so we have that:
[tex]3.2*10^5 bits[/tex]
What is the Nyquist's theorem?According to the theorem, the reconstructed signal will be equivalent to the original signal, respecting the condition that the original signal does not contain frequencies above or above this limit. This condition is called the Nyquist Criterion, or sometimes the Rahab Condition.
in this way we have:
[tex]2*14.5kHz=29kHz \\2048=2^11 =11 bits \\ 29000*11 =319000=3.2 * 10^5[/tex]

Which two statements are true about an OS? translates the user's instructions into binary to get the desired output needs to be compulsorily installed manually after purchasing the hardware is responsible for memory and device management delegates the booting process to other devices is responsible for system security Reset Next
Answer:
C. is responsible for memory and device management.
E. is responsible for system security.
Explanation:
An operating system platform 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 (OS) is essentially an interface between the computer’s hardware and all the software applications (programs) running on it.
Some examples of an operating system are QNX, Linux, OpenVMS, MacOS, Microsoft windows, IBM, Solaris, VM, Ubuntu, etc.
The two statements which are true about an operating system (OS) are;
I. It's responsible for memory and device management. The operating system (OS) ensures proper allocation of memory to processes and manages all the input/output devices that are connected to the computer.
II. It's responsible for system security. The operating system (OS) makes sure the data integrity of a computer system isn't compromised i.e determining whether or not a request is to be processed through an authentication process.
Malcolm Movers charges a base rate of $200 per move plus $150 per hour and $2 per mile. Write a program named MoveEstimator that prompts a user for and accepts estimates for the number of hours for a job and the number of miles involved in the move and displays the total moving fee. For example, if 25 hours and 55 miles are input the output would be displayed as: For a move taking 25 hours and going 55 miles the estimate is $4,060.00
Answer:
import java.util.Scanner;
public class MoveEstimator
{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
final int BASE_RATE = 200, RATE_PER_HOUR = 150, RATE_PER_MILE = 2;
int hours, miles;
double totalFee = 0.0;
System.out.print("Enter the number of hours for a job: ");
hours = input.nextInt();
System.out.print("Enter the number of miles: ");
miles = input.nextInt();
totalFee = BASE_RATE + (hours * RATE_PER_HOUR) + (miles * RATE_PER_MILE);
System.out.printf("For a move taking %d hours and going %d miles the estimate is $%.2f", hours, miles, totalFee);
}
}
Explanation:
*The code is in Java.
Create the Scanner object to be able to get input
Initialize the constant values using final keyword, BASE_RATE, RATE_PER_HOUR, RATE_PER_MILE
Declare the variables, hours, miles, totalFee
Ask the user to enter the hours and miles
Calculate the totalFee, add BASE_RATE, multiplication of hours and RATE_PER_HOUR, multiplication of miles and RATE_PER_MILE
Print the output as in required format
The program named MoveEstimator that prompts a user for and accepts estimates for the number of hours for a job and the number of miles involved in the move and displays the total moving fee is as follows:
x = int(input("number of hours for the job "))
y = int(input("number of miles involved "))
def MoveEstimator(x, y):
return 200 + 150*x + 2*y
print(MoveEstimator(x, y))
Code explanation:The first line of code used the variable, x to store the input of the hours for the jobThe second line of code is used to store the input of the number of miles travelled. Then, we define a function that accept the users inputs(argument) as variable x and y. Then return the mathematical operation to find the total moving fee.Finally, we call the function with a print statement.learn more on python code here: https://brainly.com/question/22841107

Summary: Given integer values for red, green, and blue, subtract the gray from each value.
Computers represent color by combining the sub-colors red, green, and blue (rgb). Each sub-color's value can range from 0 to 255. Thus (255, 0, 0) is bright red, (130, 0, 130) is a medium purple, (0, 0, 0) is black, (255, 255, 255) is white, and (40, 40, 40) is a dark gray. (130, 50, 130) is a faded purple, due to the (50, 50, 50) gray part. (In other words, equal amounts of red, green, blue yield gray).
Given values for red, green, and blue, remove the gray part.
Ex: If the input is:
130
50
130
the output is:
80 0 80
Find the smallest value, and then subtract it from all three values, thus removing the gray.
r=int(input("Enter the red value: "))
g=int(input("Enter the green value: "))
b=int(input("Enter the blue value: "))
m=min([r,g,b])
print(str(r-m)+" "+str(g-m)+" "+str(b-m))

Explanation:
A way to consolidate machine equipment monitoring by using programming implemented throughout the personal computer systems intimately familiar with that technology would be readily accessible. This would be widely utilized in the manufacture of thermoplastic design as well as manufacturing components.Any other solutions just shouldn't apply to the above case. So the above is the appropriate solution.
The third assignment involves writing a Python program to compute the cost of carpeting a room. Your program should prompt the user for the width and length in feet of the room and the quality of carpet to be used. A choice between three grades of carpeting should be given. You should decide on the price per square foot of the three grades on carpet. Your program must include a function that accepts the length, width, and carpet quality as parameters and returns the cost of carpeting that room. After calling that function, your program should then output the carpeting cost.
Your program should include the pseudocode used for your design in the comments. Document the values you chose for the prices per square foot of the three grades of carpet in your comments as well.
You are to submit your Python program as a text file (.txt) file. In addition, you are also to submit a test plan in a Word document or a .pdf file. 15% of your grade will be based on whether the comments in your program include the pseudocode and define the values of your constants, 70% on whether your program executes correctly on all test cases and 15% on the completeness of your test report.
Answer:
# price of the carpet per square foot for each quality.
carpet_prices=[1,2,4]
def cal_cost(width,height,choice):
return width*height*carpet_prices[choice-1]
width=int(input("Enter Width : "))
height=int(input("Enter Height : "))
print("---Select Carpet Quality---")
print("1. Standard Quality")
print("2. Primium Quality")
print("3. Premium Plus Quality")
choice=int(input("Enter your choice : "))
print(f"Carpeting cost = {cal_cost(width,height,choice)}")
Explanation:
The cal_cost function is used to return the cost of carpeting. The function accepts three arguments, width, height, and the choice of carpet quality.
The program gets the values of the width, height and choice, calls the cal_cost function, and prints out the string format of the total carpeting cost.

Explanation: An embedded computer is a microprocessor-based system, specially designed to perform a specific function and belong to a larger system. It comes with a combination of hardware and software to achieve a unique task and withstand different conditions.
Answer:
An embedded computer is a computer that has been built to solve only a very few specific questions and is not easily changed.it has a processor, software, input and output.examples are: calculator, digital camera, elevator, copiers, printers.Write a C# program named ProjectedRaises that includes a named constant representing next year’s anticipated 4 percent raise for each employee in a company. Also declare variables to represent the current salaries for three employees. Assign values to the variables, and display, with explanatory text, next year’s salary for each employee. Note: For final submission assign the following current salaries for the employees: 25000 for employee 1, 38000 for employee 2, 51000 for employee 3. Then next year's salary for employee 1 would be displayed as: Next year's salary for the first employee will be $26,000.00
Answer:
using System;
class ProjectedRaises {
static void Main() {
const float raise = 0.04f;
double salary1 = 0.0f,salary2 = 0.0f,salary3 = 0.0f;
Console.WriteLine("Current salary for each employee: ");
salary1 = Single.Parse(Console.ReadLine());
salary2 = Single.Parse(Console.ReadLine());
salary3 = Single.Parse(Console.ReadLine());
salary1 = salary1 + raise * salary1;
salary2 = salary2 + raise * salary2;
salary3 = salary3 + raise * salary3;
Console.WriteLine("Next year salary for the employees are: ");
Console.WriteLine(Math.Round(salary1));
Console.WriteLine(Math.Round(salary2));
Console.WriteLine(Math.Round(salary3));
}
}
Explanation:
This declares and initializes variable raise as a float constant
const float raise = 0.04f;
This declares the salary of each employee as double
double salary1 = 0.0f,salary2 = 0.0f,salary3 = 0.0f;
This prompts the user for the salaries of the employee
Console.WriteLine("Current salary for each employee: ");
The next three lines get the salary of the employees
salary1 = Single.Parse(Console.ReadLine());
salary2 = Single.Parse(Console.ReadLine());
salary3 = Single.Parse(Console.ReadLine());
The next three lines calculate the new salaries of the employees
salary1 = salary1 + raise * salary1;
salary2 = salary2 + raise * salary2;
salary3 = salary3 + raise * salary3;
This prints the header
Console.WriteLine("Next year salary for the employees are: ");
The next three lines print the new salaries of the employees
Console.WriteLine(Math.Round(salary1));
Console.WriteLine(Math.Round(salary2));
Console.WriteLine(Math.Round(salary3));
This is a Java programWrite a method with the following header to format the integer with the specified width. public String format(int number, int width) The method returns a string for the number with one or more prefix 0s. The size of the string is the width within the range 1 to 10000inclusive. For example, format(34, 4) returns 0034 and format(34,5) returns 00034. If the number is longer than the width, the method returns the string representation for the number. For example, format(34, 1) returns 34. Assume that, the size of the string is the width within the range 1 to 10000 inclusive and the number is an integer -2147483648 to 2147483648 inclusive.Input 34 4Output 0034You must use this particular Driver classclass DriverMain{public static void main(String args[]){Scanner input = new Scanner(System.in);int num = Integer.parseInt(input.nextLine().trim());int width = Integer.parseInt(input.nextLine().trim());GW6_P5 gw6P5 = new GW6_P5();System.out.print(gw6P5.format(num,width));}
Answer:
Following are the code to this question:
import java.util.*;//import package
public class DriverMain//defining a class DriverMain
{
public static void main(String args[])//main method
{
int num,width;
Scanner input = new Scanner(System.in);//creating Scanner class fore user input
num = Integer.parseInt(input.nextLine().trim());//input value
width = Integer.parseInt(input.nextLine().trim());//input value
GW6_P5 gw6P5 = new GW6_P5();//creating base class object
System.out.print(gw6P5.format(num,width));//print method that calls base class format method
}
}
class GW6_P5 //defining base class GW6_P5
{
String format(int number, int width)//defining method format that takes two integer variable in its parameter
{
String s = ""+number;//defining s String variable that holdes integer value
int digitCount = 0;//defining integer variable
while(number!=0) //defining while loop to check value is not equal to 0
{
digitCount++;//incrementing the integer variable value
number/=10;//holding quotient value
}
if(width>digitCount)//defining if block that checks width value greather then digitCount value
{
for(int i=0;i<width-digitCount;i++)//defining for loop to add 0 in String variable
{
s = "0"+s;//add value
}
}
return s;//return String value
}
}
Output:
34
5
00034
Explanation:
In the given code, a class "DriverMain" is defined, and inside the class main method is defined that defines two integer variable "num and width", that uses the scanner class to input the value, and in the next step the "GW6_P5" class object is created that calls the format method and print its values.
In the class "GW6_P5", the format method is defined, that declared the string and integer variables, in the while loop it checks number value not equal to 0, and increments the number values, and in the for loop it adds the 0 in string value and return its value.

A.
The owner may not be able to delete the data after the upload.
B.
The file format of the images may be corrupted.
C.
The service can sell the data without notifying the owner.
D.
People can alter the data without notifying the owner.
E.
The data is not under the owner’s direct control.
Answer: E. The data is not under the owner’s direct control.
Explanation:
A massive disadvantage to cloud storage is that the data stored is ot under the direct control of the person uploading. They first have to access the service and that service is owned by the company offering the cloud storage.
If for any reason the company decides not to give access (depending on local laws), or if the company suffers a problem that affects its ability to offer the service, the person who uploaded could lose access to their data.
Write a method named countInRange that accepts three parameters: an ArrayList of integers, a minimum and maximum integer, and returns the number of elements in the list within that range inclusive. For example, if the list v contains {28, 1, 17, 4, 41, 9, 59, 8, 31, 30, 25}, the call of countInRange(v, 10, 30) should return 4. If the list is empty, return 0. Do not modify the list that is passed in.
Answer:
In Java:
The method is as follows:
public static int countInRange (ArrayList<Integer> MyList, int min, int max) {
int count = 0;
for (int i = 0; i < MyList.size(); i++) {
if(MyList.get(i)>=min && MyList.get(i)<=max){
count++;
}
}
return count;
}
Explanation:
This defines the method
public static int countInRange (ArrayList<Integer> MyList, int min, int max) {
This declares and initializes count to 0
int count = 0;
This iterates through the ArrayList
for (int i = 0; i < MyList.size(); i++) {
This checks if current ArrayList element is between min and max (inclusive)
if(MyList.get(i)>=min && MyList.get(i)<=max){
If yes, increase count by 1
count++;
}
}
This returns count
return count;
}
To call the method from main, use:
countInRange(v,m,n)
Where v is the name of the ArrayList, m and n are the min and max respectively.
