the difference bitween hardware and software ?
Answer:
Hardware refers to the physical and visible components of the system such as a monitor, CPU, keyboard and mouse. Software, on the other hand, refers to a set of instructions which enable the hardware to perform a specific set of tasks.
Hardware is any physical part of the computer, like the monitor or keyboard. Software is the virtual part that tells the hardware what to do.
Ask the user to think of a number between zero and one hundred. Your goal is to guess the number in as few guesses as possible. The user will inform you if you guessed too high, low or correct. Start by always guessing the middle number 50. If the user informs you it’s too low, then try 75. If 50 was too high, then try 25. Always guess the middle of the range of numbers left. In doing so, the range of numbers will be cut in half after each guess. If done correctly, no more than 7 guesses are needed. Print out “you cheated” if you reach 7 guesses and are still wrong.
A program in Python that asks the user to think of a number between zero and one hundred and tries to guess the number in as few guesses as possible is given below:

Create two parallel arrays that represent a standard deck of 52 playing cards. One array is numeric and holds the values 1 through 13 (representing Ace, 2 through 10, Jack, Queen, and King). The other array is a string array that holds suits (Clubs, Diamonds, Hearts, and Spades).
Create the arrays so that all 52 cards are represented. Then, create a War card game that randomly selects two cards (one for the
player and one for the computer) and declares a winner or a tie based on the numeric value of the two cards. The game should last for 26 rounds and use a full deck with no repeated cards. For this game, assume that the lowest card is the Ace.
Display the values of the player’s and computer’s cards, compare their values, and determine the winner. When all the cards in the deck are exhausted, display a count of the number of times the player wins, the number of times the computer
wins, and the number of ties.
hints:
1) Start by creating an array of all 52 playing cards.
2) Select a random number for the deck position of the player’s first card and assign the card at that array position to the player.
3) Move every higher-positioned card in the deck “down” one to fill in the gap. In other words, if the player’s first random number is 49, select the card at position 49 (both the numeric value and the string), move the card that was in position 50 to position 49, and move the card that was in position 51 to position 50. Only 51 cards remain in the deck after the player’s first card is dealt, so the available-card array is smaller by one. In the same way, randomly select a card for the computer and “remove” the card from the deck.
Using the knowledge in computational language in python it is possible to write a code that Create the arrays so that all 52 cards are represented.

Explanation:
What percent of 2.5 hours decrease to 1 hour
Answer: 60% decrease
Explanation:
How to calculate percentage decrease:
Subtract starting value minus final value
Divide that amount by the absolute value of the starting value
Multiply by 100 to get percent decrease
If the percentage is negative, it means there was an increase and not an decrease.
Percentage Decrease Formula
You can use the percentage decrease formula for any percent decrease calculation:
Percentage Decrease=Starting Value−Final Value|Starting Value|×100
Example Problem: Percentage Decrease
You have a lamp with a 60-watt traditional light bulb. Your lamp uses 60 watts of electricity per hour. You're considering replacing the bulb with an LED light bulb that uses 8 watts of electricity per hour. What is the percentage decrease in the lamp's hourly energy use if you switch to an LED light bulb?
Percentage Decrease = [ (Starting Value - Final Value) / |Starting Value| ] × 100
60 - 8 = 52
52 / 60 = 0.8667
0.8667 × 100 = 86.67%
So if you switch to an LED light bulb your lamp will use 86.67% less energy per hour.
Related Calculators
Answer:
40%
Explanation:
Whenever we find "x" percent of a number, we simply multiply by "x/100", because "percent" just means "per 100".
We can divide the 2.5, by 100 to see how many "groups" of 100 are in 2.5, which gets us, 0.025.
Now we multiply this by some value, which will be our percent, to get "1"
So we have the equation: [tex]0.025 * x = 1[/tex]
Dividing both sides by 0.025 gives us: [tex]x=40[/tex]
so our percentage would be 40.
But generally whenever you solve these problems you convert the "percentage" to a "decimal" by dividing the percentage by 100.
So finding "x" percent of "a", can be calculated by: [tex]a*\frac{x}{100}[/tex]
and from here you would calculate the value with the givens.

A software can fool itself into believing it has a collection of linear address blocks that it can use as ordinary memory by creating the illusion of virtual memory.
Except in cases where the total quantity of virtual memory needed by all running processes exceeds the physical memory attached to the computer, it has nothing to do with the idea of secondary storage. In that instance, relatively unoccupied pages will be transferred to secondary storage; nevertheless, this is more of a "side effect" of secondary storage's handy proximity and size compared to main memory.

All academic departments in a University keeps a database of its students. Students are classified into undergraduate, graduate, and international students. There are few reasons for grouping the students into these three categories. For example the department's secretary informs: the undergraduate students about new undergraduate courses offered, the graduate students about graduate courses and professional conferences and international students about new emigration laws.
i. Identify (if any) the subtypes of entity students.
ii. Identify a unique attribute (relationship) for each subtype.
iii. Draw an EER diagram for the department's database.
The identification of subtypes of entity students may be done on the basis of students those who have taken courses on the basis of their educational qualifications.
What do you mean by the EER diagram?The EER diagram stands for the Enhanced-entity-relationship diagram. This diagram provides a visual representation of the relationship among the tables in your model. The revisions that are made with the Model editor are significantly represented in the associated diagram.
According to the context of this question, the unique attribute (relationship) for each subtype is the classification of students based on the national and international characteristics of all courses.
The EER diagram is manipulated by the structural arrangement of the classification of the students on the basis of several characteristics.

identify and explain 3 methods of automatically formatting documents
Answer:
The 3 methods used in Microsoft word to auto format are; Margin Justification, Tabular Justification, Paragraph Justification
What is formatting in Microsoft Word?
In Microsoft word, there are different ways of formatting a text and they are;
Margin justification; This is a type of formatting where all the selected text are aligned to either the left or right margin as you go to a new page as dictated by the user.
Paragraph justification; This a type of auto formatting where paragraphs are not split as they go to a new page but simply continue from where they left off.
Tabular justification; This is a type that the text is indented or aligned at a 'tab stop' to possibly show a paragraph.

SHOW ALL YOUR WORK. REMEMBER THAT PROGRAM SEGMENTS ARE TO BE WRITTEN IN
JAVA.
• Assume that the classes listed in the Java Quick Reference have been imported where appropriate.
• Unless otherwise noted in the question, assume that parameters in method calls are not null and that methods are called only when their preconditions are satisfied.
• In writing solutions for each question, you may use any of the accessible methods that are listed in classes defined in that question. Writing significant amounts of code that can be replaced by a call to one of these methods will not receive full credit.
A manufacturer wants to keep track of the average of the ratings that have been submitted for an item using a running average. The algorithm for calculating a running average differs from the standard algorithm for calculating an average, as described in part (a).
A partial declaration of the RunningAverage class is shown below. You will write two methods of the RunningAverage class.
*
public class RunningAverage
{
}
/** The number of ratings included in the running average. private int count;
/** The average of the ratings that have been entered. */ private double average;
// There are no other instance variables.
/** Creates a RunningAverage object.
* Postcondition: count is initialized to 0 and average is
* initialized to 0.0.
*/
public RunningAverage()
{ /* implementation not shown */ }
/** Updates the running average to reflect the entry of a new
* rating, as described in part (a).
*/
public void updateAverage (double newVal)
{ /* to be implemented in part (a) */ }
/** Processes num new ratings by considering them for inclusion
* in the running average and updating the running average as
necessary. Returns an integer that represents the number of
*
* invalid ratings, as described in part (b).
* Precondition: num > 0
*/
public int processNewRatings (int num)
{ /* to be implemented in part (b) */ }
/** Returns a single numeric rating.
public double getNewRating()
{ /* implementation not shown */ }
(a) Write the method updateAverage, which updates the RunningAverage object to include a new rating. To update a running average, add the new rating to a calculated total, which is the number of ratings times the current running average. Divide the new total by the incremented count to obtain the new running
average.
For example, if there are 4 ratings with a current running average of 3.5, the calculated total is 4 times 3.5, or 14.0. When a fifth rating with a value of 6.0 is included, the new total becomes 20.0. The new running average is 20.0 divided by 5, or 4.0.
Complete method updateAverage.
/** Updates the running average to reflect the entry of a new
* rating, as described in part (a).
*/
public void updateAverage (double newVal)
(b) Write the processNewRatings method, which considers num new ratings for inclusion in the running average. A helper method, getNewRating, which returns a single rating, has been provided for you.
The running average must only be updated with ratings that are greater than or equal to zero. Ratings that are less than 0 are considered invalid and are not included in the running average.
The processNewRatings method returns the number of invalid ratings. See the table below for three examples of how calls to process NewRatings should work.
Statement
Ratings

processNewRatings (2)
2.5, 4.5
processNewRatings (1)

0.0,
-2.2,
processNewRatings (4)

3.5, -1.5
Comments
Both new ratings are included
in the running average.
No new ratings are included in the running average.
Two new ratings (0.0 and 3.5) are included in the running
average.
Complete method processNewRatings. Assume that updateAverage works as specified, regardless of what you wrote in part (a). You must use getNewRating and updateAverage appropriately to receive full
credit.
/** Processes num new ratings by considering them for inclusion
* in the running average and updating the running average as
*
necessary. Returns an integer that represents the number of
* invalid ratings, as described in part (b).
* Precondition: num > 0
*/
public int processNewRatings (int num)
