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.
It's B.
As you go up, the air thins out, meaning it is less dense. Since there are less molecules that can transfer heat, the temperature is lower.
Answer:

Explanation:
e-commerce is a short for electronic commerce and it can be defined as a marketing strategy that deals with meeting the needs of consumers, by selling products or services to the consumers over the internet.
This ultimately implies that, e-commerce is strictly based on the buying and selling of goods or services electronically, over the internet or through a digital platform. Also, the payment for such goods or services are typically done over the internet such as online payment services.
Some of the benefit of introducing an e-commerce solution to an organisation's includes;
I. Improving internal communication by offering various means for exchanging information with minimum effort and cost.
II. Reducing the personalisation of services.
III. Supporting purchasing functions by offering responsive pricing models based on the analysis of market status.
Answer:
// C++ program to find k largest elements in the array
#include <bits/stdc++.h>
using namespace std;
// main function
int main()
{
// variable
int n,k;
cout<<"Enter the number of elements of array:";
// read the value of n
cin>>n;
// declare the array of size n
int arr[n];
cout<<"Enter the elements of array:";
// read the elements of array
for(int a=0;a<n;a++)
{
cin>>arr[a];
}
cout<<"Enter the value of K:";
cin>>k;
// call the function to perform selection Sort
sort(arr, arr+n);
cout << k<<" largest elements of the array are: ";
// print k largest elements of the array
for (int i=n-1; i>n-k-1; i--)
cout << arr[i] << " ";
return 0;
}
Explanation:
Read the number of elements in the array.Then create an array of size "n" and read n elements of the array.Sort the array in ascending array.Then Read the value of k from user.Find the k Elements from the end of the array.This will be the k largest elements of the array.
Output:
Enter the number of elements of array:8
Enter the elements of array:34 8 75 99 12 7 5 55
Enter the value of K:3
3 largest elements of the array are: 99 75 55
