Answer:
responsiveness and intuitive
Explanation:
The two main purposes of a good web page design is responsiveness and intuitive. A webpage needs to be designed in such a way that the individual using it can easily find what they are looking for and understand what each function in the webpage does without having to ask for help or go through an extensive tutorial. They need to be able to use the website for the first time and immediately be able to use it as if they have used it countless times before. The webpage also needs to be designed with responsiveness in mind. So much so that the webpage runs fluently, loads images fast, and scales to the size of the monitor correctly. As a rule the webpage should not take longer than 2 seconds to load.

g Write an UPDATE statement that changes the address for the row with vendor_id 4 so the suite number (Ste 260) is stored in vendor address instead of vendor address 1. Then, use SQL Developer to verify the change (you may need to click the Refresh button at the top of the Data tab to see the change). If this works correctly, go back to the tab for the UPDATE statement and click the Commit button to commit the change.
Answer:
UPDATE 'Vendors' SET 'address' = 'Ste 260' WHERE 'vendor_id' = 4
Explanation:
Required
Write an update statement
The question is incomplete as the table name is not given.
So, I will make the following assumptions.
Table name = Vendors
So, the update statement is:
UPDATE 'Vendors' SET 'address' = 'Ste 260' WHERE 'vendor_id' = 4;
The above statement queries the vendors table and changes the address of vendor_id 4 from the initial value to Ste 260

A. Incorrect selections will be penalized.
B. If I knew that the distribution of the data was significantly skewed.
C. If space were not an issue If I knew the size of the data set was very large.
D. If I knew that the data tended to be in order.
Answer:
I would select Straight 2-way Merge sort over Quicksort when:
C. If space were not an issue If I knew the size of the data set was very large.
Explanation:
For large datasets, the Straight 2-way Merge sort has been found to be more efficient than the Quicksort. It also works faster than Quicksort. However, Quicksort has been found to be more efficient, working faster than the Straight 2-way Merge sort with small datasets. The two are algorithms for sorting. While Straight 2-way Merge Sort uses two streams with repetitions, the Quicksort uses just one stream without repetitions and additional storage space.

Write the mostValuableNeighbor method, which compares the item in row r and column c to the items to its left and to its right. The method determines which of the three items has the greatest value and returns its name. If more than one of the values have a value that is greatest, then any of their names can be returned. If the item has no item to its left, it is compared only to the item to its right. If the item has no item to its right, it is compared only to the item to its left.
Answer:
Explanation:
The following method is written in Java, using the Item class and ItemGrid class found online we can use this method to grab the 2-dimensional array and compare the three neighbors in the same row. It saves the position of the neighbor with the greatest value in the variable greatest and then uses that position to call the getName() method from the object in that position to get the name of that Neighbor and returns the name.
public String mostValuableNeighbor(ItemGrid grid, int r, int c) {
int greatest = grid[r][c];
if (grid[r][c+1].getValue() > greatest.getValue()) {
greatest = grid[r][c+1];
}
if (grid[r][c-1].getValue() > greatest.getValue()) {
greatest = grid[r][c-1];
}
return greatest.getName();
}
In this exercise we have to use the knowledge of computational language in JAVA to write the code.
We have the code in the attached image.
The code in Java can be found as:
public String mostValuableNeighbor(ItemGrid grid, int r, int c) {
int greatest = grid[r][c];
if (grid[r][c+1].getValue() > greatest.getValue()) {
greatest = grid[r][c+1];
}
if (grid[r][c-1].getValue() > greatest.getValue()) {

I got it right on the Edmentum test.
Write a modular program that accepts up to 20 integer test scores in the range of 0 to 100 from the user and stores them in an array. Then main should report how many perfect scores were entered (i.e., scores of 100), using a value-returning countPerfect function to help it. Hint: Have the program count the scores as they are entered. Your program may need this information later.
Answer:
The program in Java is as follows:
import java.util.*;
public class Main{
public static int countPerfect(int [] scores, int n){
int count = 0;
for(int i = 0;i<n;i++){
if(scores[i] == 100) {count++;} }
return count; }
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
int n;
System.out.print("Number of scores: ");
n = input.nextInt();
if(n<1 || n>20){n=20;}
int [] scores = new int[n];
for(int i = 0;i<n;i++){
scores[i] = input.nextInt(); }
System.out.print("Perfect Scores: "+countPerfect(scores,n));
}
}
Explanation:
The countPerfect function begins here
public static int countPerfect(int [] scores, int n){
This initializes the count to 0
int count = 0;
This iterates through the array elements
for(int i = 0;i<n;i++){
If current score is 100, count is incremented by 1
if(scores[i] == 100) {count++;} }
This returns the value of count
return count; }
The main begins here
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
This declares the number of scores, n
int n;
Prompt to enter the number of scores
System.out.print("Number of scores: ");
This gets input for n
n = input.nextInt();
If input is less than 1 or greater than 20, n is set to 20
if(n<1 || n>20){n=20;}
This declares the scores as an array
int [] scores = new int[n];
This iterates through the array and get inputs for each score
for(int i = 0;i<n;i++){
scores[i] = input.nextInt(); }
This calls the function and print the number of perfect scores
System.out.print("Perfect Scores: "+countPerfect(scores,n));
}
The Fibonacci numbers are 0, 1, 1, 2, 3, 5, 8, 13, ......., where each number is the sum of the two preceding numbers. Write a program that declares an array of length 15 and fills the array with the first 15 Fibonacci numbers. Print the array to check if the array elements are correct. Use the sizeofoperator instead of 15 whenever you need to use the array length.

What is program?A computer can run multiple programs simultaneously, and each program can be in a different state. There are three states a program can be in: running, blocked, and ready. If a program is running, it means that it is currently using the computer's resources, such as the processor, memory, and I/O devices, to perform its tasks.
On the other hand, if a program is blocked, it means that it is waiting for a resource to become available, such as a file, network connection, or input from the user. In the scenario you mentioned, "Program A" is in the running state, meaning it is actively using the computer's resources.
Therefore, Program B" is in the blocked state, meaning it is waiting for a resource to become available so it can continue to run.

Parts arrive at a two-machine system according to an exponential interarrival distribution with mean 20 minutes. Upon arrival, the parts are sent to Machine 1 and processed. The processing-time distribution is TRIA (4.5, 9.3, 11) minutes. The parts are then processed at Machine 2 with a processing-time distribution as TRIA (16.4, 19.1, 20.8) minutes. The parts from Machine 2 are directed back to Machine 1 to be processed a second time (same processing-time distribution but an independent draw from it). The completed parts then exit the system. Run the simulation for a single replication of 20,000 minutes to observe the average number in the machine queues and the average part cycle time with Arena Model
