Answer:
c. It is an input device that enables users to convert hard copies to digital images or text.
Explanation:
An input device can be defined as any device that is typically used for sending data to a computer system.
A scanner can be defined as an input device designed for transferring informations and images from hardcopy (physical) documents to digital computer files. Thus, it's simply an electronic input device that is used to digitally scan or copy data (informations) from a hardcopy document such as photographs, paper files, printed texts etc and then converted to a digital computer file in formats such as png, or jpeg. The scanner is a device which avail users the ability and opportunity to view, edit and transfer hardcopy document on a computer system in soft-copy.
Majority of the scanners used around the world are flatbed scanners and as such have a flat glass surface for scanning documents.
Basically, all scanners are to be used with a device driver software pre-installed on the computer before the configuration of the scanner.
Other types of scanners are drum scanners, contact image sensor (CIS) scanner, CCD scanner, planetary scanner, 3D scanner, Roller scanner etc.
The range of a finite nonempty set of $n$ real numbers $S$ is defined as the difference between the largest and smallest elements of $S$. For each representation of $S$ given below, describe an algorithm in pseudo code to compute the range. Indicate the time efficiency classes of these algorithms using Big-$O$.
Answer: Hello your question is poorly written attached below is the well written question
answer:
a) Determine ( compute ) the difference between the max and minimum value. determine the Min and max values using 1.5n comparisons
time efficiency = θ( n )
b) A(n-1) - A(0)
time efficiency = θ( 1 )
Explanation:
a) An unsorted array
To find the maximum and minimum values scan the array of elements , then determine ( compute ) the difference between the max and minimum value. to determine the range. Alternatively determine the Min and max values using 1.5n comparisons
Algorithm's time efficiency = θ( n )
b) A sorted array
To determine the range, we will determine the difference between the first and last element i.e. A(n-1) - A(0)
time efficiency = θ( 1 )

Implement a program that manages shapes. Implement a class named Shape with a method area() which returns the double value 0.0. Implement three derived classes named Rectangle, Square, and Circle. Declare necessary properties in each including getter and setter function and a constructor that sets the values of these properties. Override the area() function in each by calculating the area using the defined properties in that class.
Answer:
Explanation:
The following code is written in Python. It creates the parent class Shape and the three subclasses Rectangle, Square, and Circle that extend Shape. Shape has the constructor which is empty and the area method which returns 0.0, while the three subclasses take in the necessary measurements for its constructor. Each subclass also has getter and setter methods for each variable and an overriden area() method which returns the shapes area.
class Shape:
def __init__(self):
pass
def area(self):
return 0.0
class Square(Shape):
_length = 0
_width = 0
def __init__(self, length, width):
self._width = width
self._length = length
def area(self):
area = self._length * self._width
return area
def get_length(self):
return self._length
def get_width(self):
return self._width
def set_length(self, length):
self._length = length
def set_width(self, width):
self._width = width
class Rectangle(Shape):
_length = 0
_width = 0
def __init__(self, length, width):
self._width = width
self._length = length
def area(self):
area = self._length * self._width

Explain why an immutable type cannot have a transferFrom method as specified in the Standard interface.
Answer:
The reason behind the given statement is provided below throughout the explanation portion.
Explanation:
Whenever developers operate in something like a multiprocessing atmosphere or framework, a mutable type seems to be crucial.Immutable type can't, therefore, have transferFrom methods, even if there is no constructor way for determining the further outcomes. At first, a rate is calculated while building mutable structures, thus this can never be changed.In this exercise we have to explain how it is immutable in a transferform method, like this:
The immutable type cannot have because skilled is no builder way for determining the further outcomes.
First, let's define the methods we are dealing with:
What is Transferform?Transfer Form means a standardized form prescribed by the Management Company to be duly filed by the investor to transfer Units and will be stated in this Offering Document. Immutable type can't, accordingly, have transferFrom plans, even though there is no builder habit for deciding the further effects. At first, a rate is deliberate while construction mutable forms, accordingly this can never be transformed.

A document contains a list of items that appear in no particular order. Which of the following is the best way to format the list?
Answer:
Group of answer choices.
A. Apply numbering to the list.
B. Apply bullets to the list.
C. Apply multilevel numbering to the list.
D. Manually enter a ">" character at the beginning of each item in the list.
Answer:
B. Apply bullets to the list.
Explanation:
Formatting is a feature found in a lot of word processing software applications such as Microsoft Word, Notepad, etc., which is designed to avail end users the ability to apply specific formatting options such as cut, bold, italics, underline, list, etc., to texts based on certain criteria defined by an end user.
Microsoft Word refers to a word processing software application or program developed by Microsoft Inc. to enable its users type, format and save text-based documents.
In Microsoft Word, a list can be formatted using a numbered or bulleted arrangement style. A numbered style (1, 2, 3, 4, etc) is typically used for an ordered list while a bullet is designed to be used for an unordered list.
Hence, the best way to format a document containing a list of items that appear in no particular order is to apply bullets to the list.
For example, a bulleted list of my favorite subjects arranged in no particular order would appear as this;
English language
Mathematics
Geography
Biology
Chemistry
Physics

If a program compiles fine, but it produces an incorrect result, then the program suffers from _______________.
If a program compiles fine, but it produces an incorrect result, then the program suffers from Logic Error.
What is program?A program has been the set of the instructions that the computer can follow that are written in a programming language. The size of the computer program affects the likelihood that an error may occur. To create an executable that a computer can run, a C program needs to be run through a C compiler. Programs are collections of instructions that a computer follows. Function is an ordered, reusable code unit.
When a program is syntactically sound but has a bug that is only discovered during program execution, it is said to have a runtime error. The Java compiler is unable to catch these errors during compilation; instead, the Java Virtual Machine (JVM) only notices them when the application is running. Runtime problems may occur when a website uses HTML code that is incompatible with a web browser's capabilities.
Therefore, if a program compiles fine, but it terminates abnormally at runtime, then the program suffers a runtime error.

You've run 200 ft of cable and lost 7dB. What is the loss rate of your cable per 100 ft?
Answer:Explanation: If 5 dB was lost after 200 ft of cable and 100 ft is half of 200 ft, then the rate of loss should be 2.5 dB per 100 ft.
Explanation:
The loss rate is 3.5 dB per 100 ft.
According to the question, 7 decibels were lost after running 200 ft of cable.
This means that half of 7 decibels will be lost after running 100 ft of cable.
Representing this mathematically, we will have;
200 ft = 7 dB
100 ft = ?
100 ft * 7 dB/ 200 ft
=700 dB/200
= 3.5 dB
In conclusion, 3.5 dB of cable was lost per 100 ft.

We need an equals method for the Dog class. It needs to give back to the caller a boolean value indicating whether another object of the same type's attributes are all of the same value as the calling object's. Provide the entire method (header and code), and only the method.
public class Dog {
private String name;
private int age;
private int [] healthScores;
}
Answer and Explanation:
Using Javascript:
Class Dog{
var healthScores=[];
Constructor(name, age, ...healthScores) {this.name=name;
this.age=age;
this.healthsScores=healthScores;
}
checkObject(new Dog){
If(new Dog.name===this.name,new Dog.age===this.age, new Dog.healthScores===this.healthScores){return true;
}
else{
console.log("objects are not equal");
}
}
}
To call the method checkObject:
var Tesa = new Dog(Tes,1,[45,46,82]);
var Bingo = new Dog(bing,2,[43,46,82]);
Bingo.checkObject(Tesa);
Note: we have used ES6(latest version of Javascript) where we passed the healthScore parameter(which is an array) to our constructor using the spread operator.

Explanation:
I have been working on this python program for a hour now, and I am trying to figure out what I an doing wrong in the loop. I have attached the code and screenshot of my work. I need help to figure out how to loop the rest of the years for a calculation. The calculation has looped the same result for all years.
This is the assignment:
In 2017, the tuition for a full time student is $6,450 per semester. The tuition will be going up for the next 7 years at a rate of 3.5% per year. Write your python program using a loop that displays the projected semester tuition for the next 7 years. You should display the actual year (2018, 2019, through 2024) and the tuition amount per semester for that year.
Here is my code:
# declare global constant variables
startingTuition = 6450.00;
starting_tuitionYear = 2018;
ending_tuitionYear = 2025;
increment = 1;
rate = .035;
tuition = 0;
tuitionRate = 0;
#loop for the next 7 years
for year in range(starting_tuitionYear, ending_tuitionYear, increment):
# calculate rate per year
tuitionRate = (rate)*startingTuition;
# add rate per year to the tuition fee
tuition = startingTuition + tuitionRate;
print('Tuition for the year of ' + str(year)+ ' is ' + str(tuition));
Answer:
The correct loop is as follows:
for year in range(starting_tuitionYear, ending_tuitionYear, increment):
tuition = startingTuition + rate * startingTuition
startingTuition = tuition
print('Tuition for the year of ' + str(year)+ ' is ' + str(tuition));
Explanation:

The correction to the attached program
Some variables are not needed; so, I've removed the redundant variables.
The main error in the program is in the loop;
After the tuition for each year has been calculated, the startTuition of the next year must be set to the current tuition
