Why does binary addition have a rule for 1 + 1 + 1 if only two numbers
are being added together?
Answer:
See below
Explanation:
Because sometimes you have to 'carry' a 1 over to the ext column when adding two binary numbers
Example :
1 1 1
+1 1 1 <==== starting in the first R column add 1 + 1 to get 0 and carry 1
then the next column you will add 1 + 1 + 1 = 1 and carry 1 again
then 1 + 1 + 1= 1 and carry 1 again (to column 4) to get
1 1 1 0

Calculate the standard deviation for the following data set: Data Set = 2, 9, 10, 4, 8, 4, 12
Answer:
4.24
Explanation:
First you find the mean of the data set, which is 7. Then to find standard deviation you have to follow the formula which tells you to subtract the mean from each number under the square root : √(2 - 7)^2 + (9 - 7)^2 + (10 - 7)^2 + (4 - 7)^2 + (8 - 7)^2 + (4 - 7)^2 + (12 - 7). Once you solve the parenthesis you square it, once you square it the negatives won't matter. That will leave you with this : √(25 + 4 + 9 + 9 + 25). The formula tells you to find the sum of those numbers (which is 72) then subtract one from how many numbers there are, 5 - 1 = 4, and divide your sum by that number. So 72 / 4 = 18. Then you find the square root of 18 and that becomes your answer.

Write a class called point that represents a point in 2d plane.
- the constructor accepts the x and y dimensions of the point.
- provide a method getx that returns the x coordinate of a point, and another method gety
that returns the y coordinate of a point.
- provide a method called translate that changes the original coordinates of the point by
adding a given values for x and y coordinates.
- provide a method distanceto that calculates the distance between that point and another
one.
use this equation to calculate the distance math.sqrt((x2 - x1) ** 2 + (y2 - y1) ** 2))
while the math is a library you should import. where the (x1, y) is the coordinates of the first point
and (x2, y2) is the coordinates of the second point
the output should be like this screenshot
In this way, writing the code in C++ we can say that it will be possible to make the coordinates on the planes.
Writing the code we have:#include <iostream>
#include <cmath>
#include <iomanip>
using namespace std;
class Point{
private:
float x;
float y;
public:
Point(){
x = y = 0;
}
Point(float x, float y){
this->x = x;
this->y = y;
}
float getX(){
return x;
}
float getY(){
return y;
}
float getDistance(){
return math.sqrt((x2 - x1) ** 2 + (y2 - y1) ** 2));
}
