Answer:

Data modeling occurs at three levels—physical, logical, and conceptual.

A physical model is a schema or framework for how data is physically stored in a database.

A conceptual model identifies the high-level, user view of data.

A logical data model sits between the physical and conceptual levels and allows for the logical representation of data to be separate from its physical storage.

Answer:

inspect the CPR mask and make sure that the one-way valve is correctly in place.

Explanation:

Based on the information provided within the question it seems that the next logical step would be to inspect the CPR mask and make sure that the one-way valve is correctly in place. This valve allows oxygen to be pushed into the victim's lungs but does not pull the oxygen back through the valves, that is part of the chest compression's that the person performing the CPR needs to do.

<h3>What is Life Cycle Sustainment Plan?</h3>

Life Cycle Sustainment Plan is a plan or service that works during the trade of weapons or system work regarding militarization. This system works on the development and handling of the weapon system.

So, Life Cycle Sustainment Plan will be used in the demilitarization and management requirements.

Thus, the name of the document program is Life Cycle Sustainment Plan.

Harman [31]

<u> C++ Program to Print Pascal's Triangle</u>

#include<iostream> //header file

using namespace std;

//driver function

int main()

{

int r;/*declaring r for Number of rows*/

cout << "Enter the number of rows : ";

cin >> r;

cout << endl;

for (int a = 0; a < r; a++)

{

int value = 1;

for (int b = 1; b < (r - a); b++) /*Printing the indentation space*/

{

cout << " ";

}

for (int c = 0; c <= a; c++) /*Finding value of binomial coefficient*/

{

cout << " " << value;

value = value * (a - c) / (c + 1);

Consider a physical transmission medium of capacity C bits/sec between two stations that have I bits of information sent/receive

levacccp [35]

Answer:

Check the explanation

Explanation:

when calculating the total time to send the I bits of information or The packet delivery time or latency which can be said to be the amount of time from when the first bit leaves the point of transmission until the last is received. When it comes to a physical link, it can be computed or determined as: Packet delivery time = Transmission time + Propagation delay.

Kindly check the attached image below to get the step by step explanation to the above question.
