Which of the following is true about STEM education? STEM education is focused on understanding rather than applying scientific concepts. STEM students are told to focus on a subject area and work within a certain specific field. STEM students are encouraged to blend and expand their knowledge of all four subject areas. STEM education prepares students to work in science- and math-related jobs.

Answers

Answer:

C). STEM students are encouraged to blend and expand their knowledge of all four subject areas.

Explanation:

STEM education is characterized as a learning and development approach that focuses upon an amalgamation of four subject areas including science(S), technology(T), engineering(E), and Mathematics(M). Thus, each letter stands for a subject domain and this integration of four subjects primarily aims to 'blend and expand the knowledge of the students in these areas' integratively. It helps in developing and sustaining the interests of young learners through this integrated approach which also assists them with unique opportunities. Thus, option C is the correct answer.

The answer is:

D) STEM students are encouraged to blend and expand their knowledge of all four subject areas.

Write a method mirror that accepts an ArrayList of Strings as a parameter and produces a mirrored copy of the list as output, with the original values followed by those same values in the opposite order. For example, if an ArrayList variable called list contains the values ["a", "b", "c"], after a call of mirror(list); it should contain ["a", "b", "c", "c", "b", "a"].

Answers

Answer:

Here is the JAVA program:

private static void mirror(ArrayList<String> list) { // method mirror that accepts ArrayList of Strings as a parameter

       for (int i = list.size() - 1; i >= 0; i--) {//iterates through the array list

           list.add(list.get(i));        } //produces a mirrored copy of the list

       System.out.println(list);    } ///prints the mirrored copy of list

Explanation:

This is the complete program:

import java.util.ArrayList; //to use dynamic arrays

public class MirroredArraylist{

private static void mirror(ArrayList<String> list) {    //method to produce mirrored copy of the list

       for (int i = list.size() - 1; i >= 0; i--) {  /          

           list.add(list.get(i));        }            

       System.out.println(list);    }

public static void main(String[] args) {    

     ArrayList<String> list = new ArrayList<String>();//creates a String type array list  

//adds values to the Arraylist i.e list

               list.add("a"); .

               list.add("b");

               list.add("c");        

       mirror(list); }} //calss mirror method passing list to it

The method works as follows:

For loop variable i is initialized to the list.size() - 1 which means 1 less than the size of the ArrayList i.e list. For example the list contains the following values ["a", "b", "c"]. So

i = list.size() - 1

 = 3-1

i = 2

so i is set to the last element/value of list i.e. "c"

Then the for loop checks if the value of i is greater than or equals to 0 which is true because i = 2

So the program control enters the body of the for loop

list.add(list.get(i)); This statement has two methods; add() and get()

add() method is used to add the value/element to the ArrayList, list.

get() method is used to get the element/value in list at i-th index

So the element at i=2 means element at 2nd index is "c"

Hence value "c" is added to the list.

Then the value of  i is decremented to 1. So i=1

At next iteration

i is set to the second last element/value of list i.e. "b"

Then the for loop checks if the value of i is greater than or equals to 0 which is true because i = 1

So the program control enters the body of the for loop and gets the value of list i.e "b" and adds it to the list. Next the value of "a" is get and added to the list. So the list becomes:

["c", "b", "a"]

In the main() method

               list.add("a"); .

               list.add("b");

               list.add("c");    

The above three statements adds the values to list that are "a", "b" and "c". So the list becomes:

["a", "b", "c"]

Next statement mirror(list); calls the method mirror which returns the mirrored copy of the list. So the output is:

["a", "b", "c", "c", "b", "a"].

The screen shot of the program along with its output is attached.

Given an array, x of references to objects that implement the Comparable interface, two int variables k and j that contain valid indices to x, write some statements that exchange (or swap) the contents of the elements referenced by the integers.

Answers

Answer:

Following are the code to this question:

Comparable t; //defining interface variable t

t = x[k]; //use t variable that holds array value

x[k] = x[j]; //use array to store x[j] value

x[j] = t;//use x[j] to assign value in the t

Explanation:

In the given question it is already defined " x" is an array that is the reference object, that defines the Comparable interface "t", and in the next line, two integer variable "k and j"  is defined, that swap the values.  

In the above code, the Comparable interface "t" is defined, which uses the t variable to store array x[k] value, and x[k] stores the x[j] value, and x[j] stores t value, and perform the swapping.

Which definition of AI do you like best? How would you define AI?

Consider each of them in turn and try to come up with things that they get wrong - either things that you think should be counted as AI but aren't according to the definition, or vice versa. Explain your answers by a few sentences per item (so just saying that all the definitions look good or bad isn't enough). Also come up with your own, improved definition that solves some of the problems that you have identified with the above candidates.

Explain with a few sentences how your definition may be better than the above ones?

Answers

Answer:

1. "Cool things that computers can't do"

AI is Artificial Intelligence, which can involve anything from robots to programs on computers/websites. Sure, AI can learn things and adapt in ways unlike computers, but they are still quite similar in the fact that they both are technology.

2. "Machines imitating intelligent human behavior"

This is a bit closer to the definition of AI. However, AI does not necessarily have to imitate humans - rather, it's most known for being able to adapt and learn (which is the part where this definition is correct). Also, our current AI is nowhere near the level of mimicking intelligent human behavior enough to fool us.

3. "Autonomous and adaptive systems"

This is, by far, the best definition given here yet. Most AI are autonomous and/or adaptive systems, used to automate tasks which would take time for us humans. I suppose one thing that could be wrong with it is that not all AI are made to be autonomous systems.

its known as campilation

The most appropriate word to complete the sentence is: Compilation.

Information can be defined as a set of organized and processed data that has more useful or intelligible meaning to an end user (recipient).

Generally, an information can be grouped into two (2) main categories and these includes;

Unclassified information.Classified information.

CUI is an acronym for controlled unclassified information and it can be defined as a type of information that requires safeguarding or dissemination controls which are consistent and compliant with law, standards, governmental policies and regulations.

Hence, a CUI is a federal non-classified information because it is created and possessed by the federal government or possessed on a government's behalf by an entity and as such requires some level of protection or dissemination controls from any unauthorized access and usage.

In this context, when you post two (2) pieces of controlled unclassified information (CUI) or other unclassified information together online or attach them together in an electronic mail (e-mail) and this action results in the disclosure of classified information, it is typically referred to as compilation.

In conclusion, compilation involves the process of combining two (2) pieces of controlled unclassified information (CUI) or other unclassified information together.
