Data visualization
Data visualization is a good starting point for data mining. There are several approaches to data mining that supports smart decisions. Data visualization places data in a visual context. It extracts the data in a clear and understandable way without any form of reading or writing. Results are displayed in the form of pie charts, graphs, and any other statistical representation. Such multidimensional views of data aid in developing a preliminary understanding of the trends that are hidden in the data set.
Answer:
Following are the code to the given question:
#include <iostream>//header file
using namespace std;
class Window //defining a class Window
{
private:
int width, height;//defining integer variable
public:
friend ostream& operator << (ostream& stm, Window& width)//defining a friend function that takes two parameters
{
return stm<<"a ("<<width.width<<" x "<<width.height<<") window"; //use return keyword that return its values
}
Window(int width, int height): width(width), height(height)//defining parameterized constructor that inherit width and height in its parameters
{}
};
int main() //Main method
{
Window w(80,90);//calling class constructor
cout<<w;//print object value
return 0;
}
Output:
a (80 x 90) window
Explanation:
In the above code, a class "Window" is defined that uses a friend function "ostream& operator" is declared that uses the "ostrea&" as a data type to hold two-variable "stm and w" in its parameter, and declared the parameterized constructor to hold value by inheriting width and height in its parameters.
Inside the main method, a class object is created that calls the constructor and uses the print method to print object value.
[1] is false, because we are talking about light reaching Earth's surface as a whole, and not in one specific place.
[2] is false, because even if it was in the middle of the night, the other side of the world will be recieving pretty much just as much light as you did the following day.
[3] is false, because even though the sun comes up lower during Winter months, and higher during Summer months, seasons are not constant throughout the entire world. So for what may be Winter for you, will likely be Summer for someone else, so still, just as much light is reaching the Earth.
[4] is false, because wind doesn't affect how light travels.
[5] is true, because clear skies will allow more light to come through that cloudy skies, for example, meaning the amount of light reaching the Earth's surface would not be consistent.
Answer:
The answer is "Option c"
Explanation:
In the given question only option c is correct because "/27" is the IP "255.255.255.224" is the same as "/27" in the terminology in CIDR, in which it uses the compact IP address as well as corresponding prefix expression and it terminology consists of an IP with a slash ('/') or a decimal number. Its count of 1-bit proceeding to the mask traditionally referred to it as the network mask.
