For 1.
Positive correlation means if you plot a country's population and land size on a graph. There would be a linear regression line that's sloping upwards.
Since it's a scatterplot, there will be some that fall out of the line, but most of them should be on the line.
It's (A)
For 2.
An outlier is a datapoint that's far, FAR away from the others, so it's (B)
For 3. (A), it's a single line-of-best fit that runs through the middle of the cluster of data points.
Answer:
B
Explanation:
It adds the same number over and over again, 'number' times.
This is number*number, a.k.a. number². (squared)
Answer:
//The Employee Class
public class Employee {
char name;
long ID;
//The constructor
public Employee(char name, long ID) {
this.name = name;
this.ID = ID;
}
//Method Get Person
public void getPerson (char newName, long newId){
this.ID = newName;
this.ID = newId;
}
//Method Print
public void print(){
System.out.println("The class attributes are: EmpName "+name+" EmpId "+ID);
}
}
The working of the class is shown below in another class EmployeeTest
Explanation:
public class EmployeeTest {
public static void main(String[] args) {
Employee employee1 = new Employee('a', 121);
Employee employee2 = new Employee('b', 122);
Employee employee3 = new Employee('c', 123);
employee1.print();
employee2.print();
employee3.print();
}
}
In the EmployeeTest class, Three objects of the Employee class are created.
The method print() is then called on each instance of the class.
Explanation:
The requirements would be that the receptionist robot detects the incoming person and speak;
<em>Good morning (based on time), Welcome to XYZ organization. How can i help you. Do you need to visit HR, finance, marketing, sales, engineering etc representative or other function?</em>
Now based on that a visitee information is printed out.
Limitation
A person comes who does not understand what robot speaks
Interaction with existing dialogue would be made possible through speech recognition system
The system will work well as speech recognition has now been used in many functions and robots have also now become quite advanced
