Answer:
C. Mean
Explanation:
Mean = (∑
)/N
Median = central values when data is sorted
Mode = most repeated value
Standard deviation = 
In standard deviation, formula you may see that deviation is being calculated from the mean (central location). But here we take square of the value before adding all of them.
But if we just take 
, it would be equal to zero.
<u>EXAMPLE</u>
Take 4, 9, 5 as data
mean = (4+9+5)/3 = 18/3 = 6
sum of deviations from mean = (4-6)+(9-6)+(5-6) = (-2)+(3)+(-1) = 0
Answer:
C
Explanation:
If you look at the picture, you will see why it is C. It says D, but the multiple choices are differently ordered and it is kind of differently worded.
But in conclusion, the answer is C.
Answer:
public class Leo{
public String method1(){
return "Jack 1 Leo 1";
}
public String method2(){
return "Don 2 Jack 2";
}
public String method3(){
return "Jack 3 Leo 3 Don 2";
}
public String toString(){
return "Jack 3 Leo 1"
}
}
public class Jack extends Leo{
}
Explanation:
Leo is the parent class and jack inherits all of its attributes from Leo
So when you call the following code in the main method:
Jack j = new Jack();
System.out.println(j.method1);
it should print Jack 1 Leo 1
This is because the program first checks if method 1 exists in the Jack class
Because it doesn't exist it then goes to the parent class which is Leo.
And in the Leo class method1 displays "Jack 1 Leo 1 "
So it prints that
