What does the hexadecimal number EF represent in the decimal system?

Sites like Zillow get input about house prices from a database and provide nice summaries for readers. Write a program with two

svlad2 [7]

Answer:

The program in Python is as follows:

currentPrice = int(input("Current: "))

lastMonth = int(input("Last Month: "))

print("The house is $",currentPrice)

print("The change is $",(currentPrice-lastMonth),"since last month")

print("The estimated monthly mortgage is $",(currentPrice * 0.051) / 12)

Explanation:

Get input for current price

currentPrice = int(input("Current: "))

Get input for last month price

lastMonth = int(input("Last Month: "))

Print current price

print("The house is $",currentPrice)

Print change since last month

print("The change is $",(currentPrice-lastMonth),"since last month")

Print mortgage

print("The estimated monthly mortgage is $",(currentPrice * 0.051) / 12)

Suppose we have a dictionary called grades as shown below:

mihalych1998 [28]

Answer:

import statistics as st # importing statistics package to calculate mean as st.

grades = {"John": [87,90,86.8], "Mary": [78, 81.5, 88.6],"Susan":[45,67,76]}

for key,value in grades.items():#iterating over the dictionary

average_score=st.mean(value)#calculating the mean of every student

gr="" empty string to store the grades

if average_score>=90: # nested if else if and statements for the grades in gr

gr="A"

elif average_score>=80.0 and average_score<90.0:

gr="B"

elif average_score>=70.0 and average_score<80.0:

gr="C"

elif average_score>=60.0 and average_score<70.0:

gr="D"

else :

gr="F"

print(str(key)+" "+str(average_score)+" "+str(gr)) #printing grades of every student.

Output:-Mary 82.7 B

John 87.93333333333334 B

Susan 62.666666666666664 D

Explanation:

1.In this program we are iterating over the dictionary grades.

2.Storing and calculating the mean of the scores of every student us statistics package.

3.Storing the grade in string gr and updating the gr according to the mean score

4.After that printing the grade of the student with their name and mean score.

Create an Automobile class for a dealership. Include fields for an ID number, make, model, color, year, vin number, miles per ga

aliya0001 [1]

Answer:

public class TestAutomobiles {

public static void main(String args[]) {

Automobile obj = new Automobile(1, "Wolkswagen", "Golf", 2007, "GR1GR", 20, 120, "Grey");

System.out.println("Initial Speed: " + obj.getSpeed());

System.out.println("Current Speed with acceleration 100: " + obj.accelerate(100));

System.out.println("Current Speed after using brake : " + obj.brake());

}

class Automobile {

private int idNumber, year, milesPerGallon, speed = 0;

private String model, vinNumber, make, color;

public void setIdNumber(int idNumber){

if (idNumber >= 0 && idNumber <= 9999)

this.idNumber = idNumber;

else this.idNumber = 0;

}

public void setModel(String model){

this.model = model;

}

public void setYear(int year){

if (year >= 2000 && year <= 2017)

this.idNumber = idNumber;

else this.year = 0;

}

public void setVinNumber(String vinNumber){

this.vinNumber = vinNumber;

}

public void setMilesPerGalon(int milesPerGallon){

if (milesPerGallon >= 10 && year <= 60)

this.milesPerGallon = milesPerGallon;

else this.milesPerGallon = 0;

}

public void setSpeed(int speed){

this.speed = speed;

}

public void setMake(String make){

this.make = make;

}

public void setColor(String color){

this.color = color;

}

public int getIdNumber(){return idNumber;}

public String getModel(){return model;}

public int getYear(){return year;}

public String getVinNumber(){return vinNumber;}

public int getMilesPerGallon(){return milesPerGallon;}

public int getSpeed(){return speed;}

public String getMake(){return make;}

public String getColor(){return color;}

public int accelerate() {

setSpeed(speed + 5);

return speed;

}

public int brake() {

setSpeed(speed - 5);

return speed;

}

public int accelerate(int s) {

setSpeed(speed + s);

return speed;

}

public int brake(int s) {

setSpeed(speed - s);

return speed;

}

public Automobile(int idNumber, String make, String model, int year, String vinNumber, int milesPerGallon, int speed, String color){

setIdNumber(idNumber);

setModel(model);

setYear(year);

setVinNumber(vinNumber);

setMilesPerGalon(milesPerGallon);

setSpeed(speed);

setMake(make);

setColor(color);

}

Explanation:

Required variables are declared as private members.

Their setters and getter are created.

Two accelearate and two break methods are created.

One constructor taking all variables as parameter is created.

In the main, I tested a few functions to check if they work properly.
