In the Microsoft publisher application (as well as many other websites such as Brainly, Google docs, etc), words underlined in red are spelled incorrectly.
Whether you spelled it incorrectly or did not complete the words, as long as the word is not found in the dictionary, the word would be underlined with a red squiggly line.

Answer:
//here is code in java.
import java.util.*;
class Solution
{
// main method of class
public static void main (String[] args) throws java.lang.Exception
{
try{
// declare an initialize first string variables
String st1="hello";
// declare an initialize first string variables
String st2="world";
// create another string variable
String st3;
// exchange the value of both string variables
st3=st1;
st1=st2;
st2=st3;
System.out.println("value of first String after exchange: "+st1);
System.out.println("value of second String after exchange: "+st2);
}catch(Exception ex){
return;}
}
}
Explanation:
declare and initialize two string variables.Create another string variable "st3". first assign value of "st1" to "st3" after then value of "st2" to "st1" and then assign value of "st3" to "st2". This will exchange the values of both the string.
Output:
value of first String after exchange: world
value of second String after exchange: hello
Answer: C. Cause and Effect Modelling.
Explanation:
Data Mining is a technique which aims at obtaining important and useful information in a stockpile of data. This in turn would prove useful in making predictions. It would also inform present decisions.
The Cause and Effect modelling approach explains that for every given action ( effect ), there was a prompting factor ( cause ).
In the case of Sendstars Company, the downward spiral in customer retention was as a result of ill -mannered staff. This effect, prompted the decision to have the employees trained on customer service.
Let me re-write the proposition:
p↔q⊕(¬p↔¬r)∧¬q.
Generally, the number of rows in a truth table depends on the number of Variables. Here we have 3 Variables: p,q and r. Each of them can have either the value of 1 or 0, which gives us 2*2*2 possibilities, or 2³, that is 8 possibilities and 8 rows:
p=0, q=0, r=0
p=0, q=0, r=1
p=0, q=1, r=0
p=0, q=1, r=1
p=1, q=0, r=0
p=1, q=0, r=1
p=1, q=1, r=0
p=1, q=1, r=1
