Answer:
Aggregate Function
.
Explanation:
The aggregate function returns the single value of the entire column of the database management system. The Aggregate Function is used in the SELECT statement and the GROUP BY clause.
The sum(),avg(), etc are some examples of Aggregate Function in the database with the help of aggregate function bobby gains the access to information above the usual clearance point. and summarizes the data.
Answer:
1.trees_destroyed_per_hectare = 456/2.47
2. input(no_of_hectares)
3. no_of_trees_destroyed =no_of_hectares * trees_destroyed_per_hectare
4. print(no_of_trees_destroyed)
Explanation:
1.trees_destroyed_per_hectare = 456/2.47 //conversion of tress destroyed per acres to hectare
2. input(no_of_hectares) // get input from user in hectares that how many hectares are destroyed
3. no_of_trees_destroyed =no_of_hectares * trees_destroyed_per_hectare // total number of trees destroyed by fire on given day and given area
4. print(no_of_trees_destroyed)

Answer:
#include <iostream>
#include <iomanip>
using namespace std;
int main()
{
double side, height;
cout<<"Enter the length of one of the sides of the base: ";
cin>>side;
cout<<"Enter the height: ";
cin>>height;
double area = side * side;
double volume = area * height / 3;
cout<<"The area of the base of the pyramid is: "<<area<<endl;
cout<<"The height of the pyramid is: "<<height<<endl;
cout<<"The volume of the pyramid is: "<<fixed<<setprecision(2)<<volume<<endl;
return 0;
}
<u>Pseudocode:</u>
Declare side, height
Get side
Get height
Set area = side * side
Set volume = area * height / 3
Print area
Print height
Print volume
Explanation:
Include <iomanip> to have two decimal places
Declare the side and height
Ask the user to enter side and height
Calculate the base area, multiply side by side
Calculate the volume using the given formula
Print area, height and volume (use <em>fixed</em> and <em>setprecision(2)</em> to have two decimal places)
The best and most correct answer among the choices provided by your question is the third choice or letter C. A bar graph resembles histogram the most.
A histogram<span> is a graphical representation of the distribution of numerical data. It is an estimate of the probability distribution of a continuous variable (quantitative variable) and was first introduced by Karl Pearson.
