Answer:

See explaination

Explanation:

E-R diagram:

Entity Relationship Diagram, also known as ERD, ER Diagram or ER model, is a type of structural diagram for use in database design. An ERD contains different symbols and connectors that visualize two important information: The major entities within the system scope, and the inter-relationships among these entities.

In this scenario, two friends are eating dinner at a restaurant. The bill comes in the amount of 47.28 dollars. The friends deci
pickupchik [31]

Answer:

The java program for the given scenario is as follows.

import java.util.*;

import java.lang.*;

public class Main

{

   //variables for bill and tip declared and initialized

   static double bill=47.28, tip=0.15;

   //variables for total bill and share declared

   static double total, share1;

public static void main(String[] args) {

    double total_tip= (bill*tip);

    //total bill computed

    total = bill + total_tip;

    //share of each friend computed

    share1 = total/2;

    System.out.printf("Each person needs to pay: $%.2f", share1);  

}

}

Explanation:

1. The variables to hold the bill and tip percent are declared as double and initialized with the given values.

static double bill=47.28, tip=0.15;

2. The variables to hold the values of total bill amount and total tip are declared as double.

3. All the variables are declared outside main() and at class level, hence declared as static.

4. Inside main(), the values of total tip, total bill and share of each person are computed as shown.

double total_tip= (bill*tip);

total = bill + total_tip;

share1 = total/2;

5. The share of each person is displayed to the user. The value is displayed with only two decimal places which is assured by %.2f format modifier. The number of decimal places required can be changed by changing the number, i.e. 2. This format is used with printf() and not with println() method.

System.out.printf("Each person needs to pay: $%.2f", share1);  

6. The program is not designed to take any user input.

7. The program can be tested for any value of bill and tip percent.

8. The whole code is put inside a class since java is a purely object-oriented language.

9. Only variables can be declared outside method, the logic is put inside a method in a purely object-oriented language.

10. As shown, the logic is put inside the main() method and only variables are declared outside the method.

11. Due to simplicity, the program consists of only one class.

12. The output is attached.

2. Consider a 2 GHz processor where two important programs, A and B, take one second each to execute. Each program has a CPI of
allsm [11]

Answer:

program A runs in 1 sec in the original processor and 0.88 sec in the new processor.

So, the new processor out-perform the original processor on program A.

Program B runs in 1 sec in the original processor and 1.12 sec in the new processor.

So, the original processor is better then the new processor for program B.

Explanation:

Finding number of instructions in A and B using time taken by the original processor :

The clock speed of the original processor is 2 GHz.

which means each clock takes, 1/clockspeed

= 1 / 2GH = 0.5ns

Now, the CPI for this processor is 1.5 for both programs A and B. therefore each instruction takes 1.5 clock cycles.

Let's say there are n instructions in each program.

therefore time taken to execute n instructions

= n * CPI * cycletime = n * 1.5 * 0.5ns

from the question, each program takes 1 sec to execute in the original processor.

therefore

n * 1.5 * 0.5ns = 1sec

n = 1.3333 * 10^9

So, number of instructions in each program is 1.3333 * 10^9

the new processor :

The cycle time for the new processor is 0.6 ns.

Time taken by program A = time taken to execute n instructions

=  n * CPI * cycletime

= 1.3333 * 10^9 * 1.1 * 0.6ns

= 0.88 sec

Time taken by program B = time taken to execute n instructions

= n * CPI * cycletime

= 1.3333 * 10^9 * 1.4 * 0.6

= 1.12 sec

Now, program A runs in 1 sec in the original processor and 0.88 sec in the new processor.

So, the new processor out-perform the original processor on program A.

Program B runs in 1 sec in the original processor and 1.12 sec in the new processor.

So, the original processor is better then the new processor for program B.

How can i change ip address <br>​
JulijaS [17]

I believe your answer would be:

1: Open the command prompt window. Do this by clicking the "Start" button, and then selecting "Run." In the window that appears, type "cmd" into the text box and click the "OK" button.

2: Release the computer's current IP address. To do this, type "ipconfig /release" into the command prompt window and press Enter.

3: Acquire a new IP address. Do this by typing "ipconfig /renew" into the command prompt window and pressing Enter. This should assign the computer a new IP address, which will be different from the previous address.

4: Cycle your modem's power. If the above steps don't work, you can try renewing your IP address by cycling your modem's power. Turn off both your computer and your modem (and your router, if you have one). Wait at least 5 minutes, then turn everything back on. If your computer is set to receive an IP address dynamically (the most likely configuration), you should be assigned a new IP address automatically.

5: Check to make sure your IP address has changed. To do this, you can log on to a number of different websites that tell you your IP address.

Hope I helped, if so may I get brainliest and a thanks?

Thank you, Have a good day! =)
