Explanation:
A specification can be a written document, a set of graphical, a formal mathematical model, a collection of usage scenarios (or, use cases), a prototype, or any combination of these.
A. True
B. False
Answer:
The given statement is "True". A further explanation is given below.
Explanation:
The specification would be a necessary condition that is explicitly indicated, for obvious reasons, concerning the great components throughout the prototype of being something. A detailed explanation of that same performance aspects, normally with particular established standards, is presented in terms appropriate to lead to the creation both for real manufacturing and building methods of such a component with either the personality traits mentioned throughout the structural performance.So the above is the appropriate response.
Write a public static method named insert. The insert method should have the signature insert(String[] words, String newWord, int place), should return a boolean, and should function as described below.
When called, if place does not represent a valid index for words, then the method will return false to indicate the insertion could not be performed and do nothing else. Otherwise the method will insert the String newWord into the array words at the index place, moving each subsequent entry one place further and losing the final String in the array. The method will then return true to indicate the insertion has taken place.
Use the runner class to test this method: do not add a main method to your code in the U6_L4_Activity_One.java file or it will not be scored correctly.
Here is the runner code:
import java.util.Scanner;
public class runner_U6_L4_Activity_One{
public static void main(String[] args){
Scanner scan = new Scanner(System.in);
System.out.println("Enter array length:");
int len = scan.nextInt();
scan.nextLine();
String[] wordList = new String[len];
System.out.println("Enter values:");
for(int i = 0; i < len; i++){
wordList[i] = scan.nextLine();
}
System.out.println("Enter new String:");
String insWord = scan.nextLine();
System.out.println("Enter place:");
int pos = scan.nextInt();
System.out.println("Method return: " + U6_L4_Activity_One.insert(wordList, insWord, pos));
System.out.print("Array contents: {");
for(int i = 0; i < len-1; i++){
System.out.print(wordList[i] + ", ");
}
System.out.println(wordList[len-1]+"}");
}
}
Answer:
Explanation:
The following code was written in Java and performs the exact requirements listed in the question. It has also been tested by the runner code and works perfectly.
public static boolean insert(String[] words, String newWord, int place) {
if (place > words.length) {
return false;
} else {
for (int x = words.length - 1; x >= 0; x--) {
if (place == x) {
words[x] = newWord;
break;
} else {
words[x] = words[x-1];
}
}
return true;
}
}
Methods are group of code segments that are executed when evoked or called.
The insert public static method in Java, where comments are used to explain each line is as follows:
//This defines the method
public static boolean insert(String[] words, String newWord, int place) {
//This returns false, if the place value is less than the word length
if (place > words.length) {
return false;
}
//If otherwise
else {
//This iterates through the characters of the word, in reverse order
for (int i = words.length - 1; i >= 0; i--) {
//This inserts the new word into the array
if (place == i) {
words[i] = newWord;
break;
} else {
words[i] = words[i-1];
}
}
//This returns true
return true;
}

Your task is to implement a function replace_once(t, d), that takes a text t and a replacement dictionary d, and returns the result of replacing words according to the dictionary: if a word appears as a key, replace it with the dictionary value, and if a word does not appear in the dictionary, leave it alone.
Given a list of words, you can concatenate them together with spaces in between as follows:
word_list = "I love eating bananas".split()
print("Word list:", word_list)
back_together = " ".join(word_list)
print("Back together:", back_together)
# You can also join them in other ways, btw. Just DON'T do it for this homework.
print("You can also put commas:", ", ".join(word_list))
Answer:
Explanation:
The following code is written in Python and does exactly as requested. It is a function named replace_one(t, d) that takes the two parameters one text/word and one dictionary. If the word is found as a key in the dictionary it places the value in a variable called new_word and returns it to the user, if it is not found then the function returns nothing.
def replace_once(t, d):
if t in d:
new_word = d.get(t)
return new_word

Ways information technology does not make us productive
Answer:
Although technology is moving the limits, its power is not always helpful.
Explanation:
Technology can make us very non-productive, as it takes time away from our most productive hours when we use our productive time to scroll social media.
Notifications can interrupt the concentration. It makes us lazy in the morning, when, instead of being productive, we are reading anything online.
It can impact our sleep, anxiety, and it may force us to spend time creating a false image of ourselves.
A user reports slow performance on a computer. A technician checks the computer and finds the RAM utilization Is very high. The technician restarts the computer, and the RAM use is still high. The technician discovers a program running in the background Is using most of the RAM. The user only uses this program once at the end of the year to produce a report. What steps should the technician take to improve the computer's performance?
Answer:
The answer is "disable the program on startup"
Explanation:
The technician simply disables the program on the startup, at this the utilization of the RAM is low. The startup tab is also known as an alternative in the initialization process of the system software, which is automatically started whenever the device boots. There has been an error. If you boot, the more applications you want to load the longer it will take to operate the computer.

Explanation:
The power relationship on a transformer states that Power in = power out + loss.
What relationship does input and output power have in a transformer?The ratio between output voltage and input voltage exists the exact as the ratio of the number of turns between the two windings
The efficiency of a transformer exists reflected in power (wattage) loss between the primary (input) and secondary (output) windings. Then the consequent efficiency of a transformer stands equivalent to the ratio of the power output of the secondary winding, PS to the power input of the primary winding, PP and exists thus high.

Write a program that calculates the shipping charges for parcel. The program should ask the user to enter two floating point values:
The weight of a parcel in pounds
The shipping rate per pound
The program calculates and displays the total shipping charges based on the parcel’s weight and shipping rate per pound.
Your program should print dollars and cents with two decimal places such as 32.85, and not 32.8467777.
Hint: Until we learn how to format output, we will use this little trick. You can round a floating-point value to the nearest hundredth by adding 0.005, multiplying by 100, converting the result to an integer, and then dividing by 100. This trick is not perfect but works well with most values.
Here is a sample of what a typical run of this program looks like where the user entered the values 4.75 for the weight and 2.55 for the shipping rate per pound:
Shipping Charges Calculator
Enter the weight of your parcel in pounds: 4.75
Enter the shipping price per pound: 2.55
The weight of your parcel is 4.75 pounds
The shipping price per pound is $ 2.55
The shipping charges for your parcel is $ 12.11
NOTE: Please remember that your program will be graded in terms of:

/* missing precondition */
public String getChar(String str, int n) {
return str.substring(n, n 1); }
Write down the most appropriate precondition for the method so that it does not throw an exception.
Answer:
An appropriate precondition is:
0 <= n && n <= str.length() - 1
Explanation:
Required:
Write down an appropriate pre-condition for the program
From the question, we understand that the method accepts two parameters:
str -> A string value
n -> An integer value which represents the index of character to return from the string str
It should be noted that:
n must be within the range of 0 and str.length()-1
Take for instance:
str = "ABCDE";
n must be within the range 0 to 4 (inclusive) in order not to raise an exception. This is so because the string index starts at 0 and stops at 1 less than the length of the string.
Hence, the precondition can be written as:
0 <= n && n <= str.length() - 1
Which means: n = 0 to length - 1

Write a class called Person that has two data members - the person's name and age. It should have an init method that takes two values and uses them to initialize the data members.Write a separate function (not part of the Person class) called std_dev that takes as a parameter a list of Person objects (only one parameter: person_list) and returns the standard deviation of all their ages (the population standard deviation that uses a denominator of N, not the sample standard deviation, which uses a different denominator).
Answer:
class Person(object):
def __init__(self, name, age):
self.name = name
self.age = age
def std_dev(person_list):
average = 0
for person in person_list:
average += person.age
average /= len(person_list)
total = 0
for person in person_list:
total += (person.age - average) ** 2
return (total / (len(person_list) )) ** 0.5
Explanation:
The class "Person" is a python program class defined to hold data of a person (name and age). The std_dev function accepts a list of Person class instances as an argument and returns the calculated standard deviation of the population.
A Consider the following method definition. The method printAllCharacters is intended to print out every character in str, starting with the character at index 0. public static void printAllCharacters (String str) for (int x = 0; x< str.length(); x++) // Line 3 System.out.print(str.substring(x, x + 1)); The following statement is found in the same class as the printAllCharacters method. printAllCharacters ("ABCDEFG"); Which choice best describes the difference, if any, in the behavior of this statement that will result from changing x < str.length() to x <= str.length() in line 3 of the method?
Α) The method call will print fewer characters than it did before the change because the loop will iterate fewer times.
B) The method call will print more characters than it did before the change because the loop will iterate more times.
C) The method call, which worked correctly before the change, will now cause a run-time error because it attempts to access a character at index 7 in a string whose last element is at index 6.
D) The method call, which worked correctly before the change, will now cause a run-time error because it attempts to access a character at index 8 in a string whose last element is at index 7.
E) The behavior of the code segment will remain unchanged.
Answer:
(c) The method call, which worked correctly before the change, will now cause a run-time error because it attempts to access a character at index 7 in a string whose last element is at index 6.
Explanation:
Given
printAllCharacters method and printAllCharacters("ABCDEFG");
Required
What happens when x < str.length() is changed to x <= str.length()
First, we need to understand that str.length() gets the length of string "ABCDEFG"
There are 7 characters in "ABCDEFG".
So: str.length() = 7
The first character is at index 0 and the last is at index 6
Next, we need to simplify the loop:
for (int x = 0; x< str.length(); x++) means for (int x = 0; x< 7; x++)
The above loop will iterate from the character at the 0 index to the character at the 6th index
while
for (int x = 0; x<=str.length(); x++) means for (int x = 0; x<=7; x++)
The above loop will iterate from the character at the 0 index to the character at the 7th index
Because there is no character at the 7th index, the loop will return an error
Hence: (c) is correct
Following are calculations to the given method.
Given:
Method printAllCharacters and printAllCharacters("ABCDEFG") are both required.
To find:
What happens if you change x <str.length() to x = str.length()?
Solution:
To begin, we must recognize that str. length() returns the length of the string "ABCDEFG"."ABCDEFG" is made up of seven letters.As just a result, str.length() = 7The first character is at index 0 while the last is at index 6. The loop should therefore be simplified:
for (int x = 0; x< str.length(); x++) means for (int x = 0; x< 7; x++)
Its loop above should iterate from character 0 through character 6.when
for (int x = 0; x<=str.length(); x++) stands as for (int x = 0; x<= 7; x++).
The loop above will iterate from the character from index 0 to a character at index 7.The loop will produce an error since there are no characters at the 7th index.Therefore, the final answer is "Option (c)"
