Answer:

A. With content-based filtering, users

receive recommendations for items

liked by similar users.

Explanation:

A database management system (DBMS) can be defined as a collection of software applications that typically enables computer users to create, store, modify, retrieve and manage data or informations in a database. Generally, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security.

A data dictionary can be defined as a centralized collection of information on a specific data such as attributes, names, fields and definitions that are being used in a computer database system.

In a data dictionary, data elements are combined into records, which are meaningful combinations of data elements that are included in data flows or retained in data stores.

This ultimately implies that, a data dictionary found in a computer database system typically contains the records about all the data elements (objects) such as data relationships with other elements, ownership, type, size, primary keys etc. This records are stored and communicated to other data when required or needed.

Content-based filtering uses an algorithm to recommend to users what they like.

The statement about content-based filtering which is false is that, with content-based filtering, users

receive recommendations for items

liked by similar users.

Your ___________ is what you can see without the presence of an obstruction.

SCORPION-xisa [38]

Answer:

Line of sight

Explanation:

Your line of sight is the noticeable path of travel from your vehicle to your destination area. This line can be obstructed by a curve, a hill, high-forest wooded zones, large trucks, or other obstruction that prevents drivers from seeing the vehicle ahead. Therefore, if you cannot see around an obstruction, you should slow down and be willing to adjust your position until you can reestablish a clear line of sight to your path of travel and targeting area.

What is the output of the following C++ program?

KIM [24]

Answer:

Output:<em> </em><em>15 11/16 inches</em>

Explanation:

#include <iostream>

using namespace std;

////////////////////////////////////////////////////////////////////////

class InchSize {

public:

InchSize(int wholeInches = 0, int sixteenths = 0);

void Print() const;

InchSize operator+(InchSize rhs);

private:

int inches;

int sixteenths;

};

InchSize InchSize::operator+(InchSize rhs) {

InchSize totalSize;

totalSize.inches = inches + rhs.inches;

totalSize.sixteenths = sixteenths + rhs.sixteenths;

// If sixteenths is greater than an inch, carry 1 to inches.

if (totalSize.sixteenths >= 16) {

totalSize.inches += 1;

totalSize.sixteenths -= 16;

}

return totalSize;

}

InchSize::InchSize(int wholeInches, int sixteenthsOfInch) {

inches = wholeInches;

sixteenths = sixteenthsOfInch;

}

void InchSize::Print() const {

cout<<inches<<" "<<sixteenths<<"/16 inches"<<endl;

}

////////////////////////////////////////////////////////////////////////

int main() {

InchSize size1(5, 13);

InchSize size2(9, 14);

InchSize sumSize;

sumSize = size1 + size2;

sumSize.Print();

return 0;

}

////////////////////////////////////////////////////////////////////////

sumSize variable was printed in the end. Print() prints the calling object's inches and sixteenths variables' values.

sumSize's inches is equal to size1 plus size2's inches.

Because the sum of sixteenths was greater than 16, sumSize's sixteenth was decreased by 1 and inches was increased by 1.
