The are two schools of ____________ are Symmetry and Asymmetry.
The two schools of design that encompass symmetry and asymmetry are known as symmetrical design and asymmetrical design.
Symmetrical design is characterized by the balanced distribution of visual elements on either side of a central axis. It follows a mirror-like reflection, where the elements on one side are replicated on the other side, creating a sense of equilibrium and harmony.
Symmetrical designs often evoke a sense of formality, stability, and order.
On the other hand, asymmetrical design embraces a more dynamic and informal approach. It involves the intentional placement of visual elements in an unbalanced manner, without strict adherence to a central axis.
Asymmetrical designs strive for a sense of visual interest and tension through the careful juxtaposition of elements with varying sizes, shapes, colors, and textures.
They create a more energetic and vibrant visual experience.
Both symmetrical and asymmetrical design approaches have their merits and are employed in various contexts. Symmetry is often used in formal settings, such as architecture, classical art, and traditional graphic design, to convey a sense of elegance and tradition.
Asymmetry, on the other hand, is commonly found in contemporary design, modern art, and advertising, where it adds a sense of dynamism and creativity.
In conclusion, the schools of symmetry and asymmetry represent distinct design approaches, with symmetrical design emphasizing balance and order, while asymmetrical design embraces a more dynamic and unbalanced aesthetic.

Answer:
quality
Explanation:
if i know about the phone or laptop quality and quantity then i can know which is important if i buy.
i can give you example by laptop. For example i want to get buy laptop. i should know about the quantity and quality. then if i choose quantity i can buy so many laptops if they are more than 3 laptops and i get it in low price. then i take it and i try to open the laptops for some other thing to do but they cant opened so it means it has lowest quality.
and if i choose the quality. may be i can't buy more than 1 laptops but the qulaity of the laptops is high so when i open the laptop it opened
Notequality is the superiority or the quality level of a things.
quantity is the abundance or the quantity level of a thing

You would like to create a practical program that will randomly select student names from a list for your instructor to be able to call on people. What are the steps for creating this program? Explain your answer in 3-5 sentences
To create a program that randomly selects student names from a list, begin by crafting the roster. Names can be manually typed or loaded from a saved document.
What is the next step?Next, generate a random number that falls within the range of the listed students. This created value will coincide with the assigned index for selection.
To avoid repetitiveness until all names have been used, display the chosen name to your preference and remove it from the list. For this project any programming language could suffice, however, selecting an easily readable option like Python is highly recommended.
It readily enables loading information from files as well as generating appropriately guided random numbers.

4.15 LAB: Mad Lib - loops
Mad Libs are activities that have a person provide various words, which are then used to complete a short story in unexpected (and hopefully funny) ways.
Write a program that takes a string and an integer as input, and outputs a sentence using the input values as shown in the example below. The program repeats until the input string is quit and disregards the integer input that follows.
Ex: If the input is:
apples 5
shoes 2
quit 0
the output is:
Eating 5 apples a day keeps you happy and healthy.
Eating 2 shoes a day keeps you happy and healthy
Answer:
Explanation:
import java.util.Scanner;
public class MadLibs {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
String word;
int number;
do {
System.out.print("Enter a word: ");
word = input.next();
if (word.equals("quit")) {
break;
}
System.out.print("Enter a number: ");
number = input.nextInt();
System.out.println("Eating " + number + " " + word + " a day keeps you happy and healthy.");
} while (true);
System.out.println("Goodbye!");
}
}
In this program, we use a do-while loop to repeatedly ask the user for a word and a number. The loop continues until the user enters the word "quit". Inside the loop, we read the input values using Scanner and then output the sentence using the input values.
Make sure to save the program with the filename "MadLibs.java" and compile and run it using a Java compiler or IDE.
You are given an array of integers, each with an unknown number of digits. You are also told the total number of digits of all the integers in the array is n. Provide an algorithm that will sort the array in O(n) time no matter how the digits are distributed among the elements in the array. (e.g. there might be one element with n digits, or n/2 elements with 2 digits, or the elements might be of all different lengths, etc. Be sure to justify in detail the run time of your algorithm.
Answer:
Explanation:
Since all of the items in the array would be integers sorting them would not be a problem regardless of the difference in integers. O(n) time would be impossible unless the array is already sorted, otherwise, the best runtime we can hope for would be such a method like the one below with a runtime of O(n^2)
static void sortingMethod(int arr[], int n)
{
int x, y, temp;
boolean swapped;
for (x = 0; x < n - 1; x++)
{
swapped = false;
for (y = 0; y < n - x - 1; y++)
{
if (arr[y] > arr[y + 1])
{
temp = arr[y];
arr[y] = arr[y + 1];
arr[y + 1] = temp;
swapped = true;
}
}
if (swapped == false)
break;
}

A buffer is filled over a single input channel and emptied by a single channel with a capacity of 64 kbps. Measurements are taken in the steady state for this system with the following results:
Average packet waiting time in the buffer = 0.05 seconds
Average number of packets in residence = 1 packet
Average packet length = 1000 bits
The distributions of the arrival and service processes are unknown and cannot be assumed to be exponential.
Required:
What are the average arrival rate λ in units of packets/second and the average number of packets w waiting to be serviced in the buffer?
Answer:
a) 15.24 kbps
b) 762 bits
Explanation:
Using little law
a) Determine the average arrival rate ( λ ) in units of packets/s
λ = r / Tr --- 1
where ; r = 1000 bits , Tr = Tw + Ts = 0.05 + (( 1000 / (64 * 1000 )) = 0.0656
back to equation 1
λ = 1000 / 0.0656 = 15243.9 = 15.24 kbps
b) Determine average number of packets w to be served
w = λ * Tw = 15243.9 * 0.05 = 762.195 ≈ 762 bits

Over the course of a few decades, the internet has changed the way we work, the way we play and the way we interact with one another. Depending on how it’s used, it bridges nations, drives commerce, nurtures relationships, drives the innovation engine of the future and is responsible for more memes than we know what to do with.
Explanation:
Consider sorting n numbers stored in array A by first finding the smallest element of A and exchanging it with the element in A[1]. Then find the second smallest element of A, and exchange it with A[2]. Continue in this manner for the first n − 1 elements of A. Write pseudocode for this algorithm, which is known as selection sort. What loop invariant does this algorithm maintain? Why does it need to run for only the first n − 1 elements, rather than for all n elements? Give the best–case and worst–case running times of selection sort in Θ–notation.
Answer:
1. create the first array A
2. create the second array A1, the same length as array A.
3. create a loop to iterate over both arrays for a number of times specific to the length of the arrays, with a condition to get and pop only the minimum value of which arrays for every loop.
4. save both items to "a" for minimum value A and "b" for minimum value A1.
5. call a function to push the "a" variable value to A1 and "b" variable value to the array A.
Explanation:
This code would interchange the values of both arrays, the best-case scenario for the code is O( n ) where n is the number of items in both arrays and worst is the best-case multiplied by the number of time to compare all the items with the minimum value.
