Write a program that accepts three decimal numbers as input and outputs their sum

Sophie [7]

Answer:

sum = 0.0

for i in range(0,3):

sum += float(input("Enter a decimal number to sum: "))

print ("Sum: ", sum)

*** Sample Input ***

Enter a decimal number to sum: 1.1

Enter a decimal number to sum: 2.2

Enter a decimal number to sum: 3.3

*** Sample Output ***

Sum: 6.6

Explanation:

For this problem, a method was devised in python to create the sum of three individual decimal numbers.

The first line of code, sum = 0.0, initializes a variable to the float type in which we will store the value of our sum. Note, it is initialized to 0.0 to start from a value of 0 and be considered a float.

The second line of code, for i in range(0,3): is the creation of a for loop control structure. This will allow us to repeat a process 3 amount of times using the iterator i, from value 0 to 3 in this case. Note, 0 is inclusive and 3 is exclusive in the python range. This means the for loop will iterate with, i=0, i=1, and i=2.

The third line of code, sum += float(input("Enter a decimal number to sum: ")) is simply asking the user for a number, taking that input and converting it from a string into a float, and then summing the value with the previous value of sum and saving that into sum.

The fourth line of code, print ("Sum: ", sum) is simply displaying the final value that was calculated by adding the three user inputs together which were stored into the variable sum.

Cheers.

lions [1.4K]

Answer:

0.119

Explanation:

50 independent fair games

Mean will be 50/2 = 25

Standard deviation of the loosing probability is :

$\sqrt{50*0.5*0.5}$ * 10 = 33.536

we have to loose 33 times out of 50 games.

To find the approximate probability we use z- value table.

z value = $\frac{33-25}{3.35}$

z - value = 2.2659

Looking at the z-value table we get 0.119.

What is database design?

finlep [7]

Answer: Database design is the model created of data/information for any particular organization .the relation between the information and which data is to be stored is the most important factor for designing .These parameters are decided by the designer of the database.

After the decision of the designed the data is invoked in the database .The data representation in the theoretical manner is known as ontology.The classification and relation defining is the purpose of the database design.

Write a Python 3 program that will compute the total cost of an amazon purchase. The program should ask the user to enter the am

valentina_108 [34]

Answer:

price = float(input("Enter amount of a purchase: "))

shipping_price = 0.12* price

NJ_sales_Tax = 0.07*price

print('The price of item is {}'.format(price))

print('The Cost of Shipping is {}'.format(shipping_price) )

print('New Jessey Sales Tax is {}'.format(NJ_sales_Tax))

total_bill = shipping_price+NJ_sales_Tax+price

print('Total Bill {} ' .format(total_bill))

Explanation:

Prompt User for input of the amount of purchase
Calculate the shipping cost (12% of purchase price)
Calculate the tax (7% of the purchase price)
Use python's .format method to output an itemized bill

Design a class named Complex for representing complex numbers and the methods add, subtract, multiply, divide, abs for performin

Tanzania [10]

Answer:

Explanation:

The following code is written in Java, it creates the entire complex class as requested so that it works with the main method that has been provided in the question without having to change anything in the main method. Proof of output can be seen in the attached picture below

import java.util.Scanner;

class Test implements Cloneable{

public static void main(String[] args) {

Scanner input = new Scanner(System.in);

System.out.print("Enter the first complex number: ");

double a = input.nextDouble();

double b = input.nextDouble();

Complex c1 = new Complex(a, b);

System.out.print("Enter the second complex number: ");

double c = input.nextDouble();

double d = input.nextDouble();

Complex c2 = new Complex(c, d);

System.out.println("(" + c1 + ")" + " + " + "(" + c2 + ")" + " = " + c1.add(c2));

System.out.println("(" + c1 + ")" + " - " + "(" + c2 + ")" + " = " + c1.subtract(c2));

System.out.println("(" + c1 + ")" + " * " + "(" + c2 + ")" + " = " + c1.multiply(c2));

System.out.println("(" + c1 + ")" + " / " + "(" + c2 + ")" + " = " + c1.divide(c2));

System.out.println("|" + c1 + "| = " + c1.abs());

Complex c3 = c1;

System.out.println(c1 == c3);

System.out.println(c3.getRealPart());

System.out.println(c3.getImaginaryPart());

}

class Complex implements Cloneable {

public interface Cloneable { }

private double realPart;

public double getRealPart() {

return realPart;

}

public void setReal(double real) {

this.realPart = real;

}

private double imaginaryPart;

public double getImaginaryPart() {

return imaginaryPart;

}

public void setImaginary(double imaginary) {

this.imaginaryPart = imaginary;

}

public Complex(double a, double b) {

realPart = a;

imaginaryPart = b;

}

public Complex(double a) {

realPart = a;

imaginaryPart = 0;

}

public Complex() { }

public Complex add(Complex comp2) {

double real1 = this.getRealPart();

double real2 = comp2.getRealPart();

double imaginary1 = this.getImaginaryPart();

double imaginary2 = comp2.getImaginaryPart();

return new Complex(real1 + real2, imaginary1 + imaginary2);

}

public Complex abs() {

double real1 = Math.abs(this.getRealPart());

double imaginary1 = Math.abs(this.getImaginaryPart());

return new Complex(real1, imaginary1);

}

public Complex subtract(Complex comp2) {

double real1 = this.getRealPart();

double real2 = comp2.getRealPart();

double imaginary1 = this.getRealPart();

double imaginary2 = comp2.getRealPart();

return new Complex(real1 - real2, imaginary1 - imaginary2);

}

public Complex multiply(Complex comp2) {

double real1 = this.getRealPart();

double real2 = comp2.getRealPart();

double imaginary1 = this.getRealPart();

double imaginary2 = comp2.getRealPart();

return new Complex(real1 * real2, imaginary1 * imaginary2);

}

public Complex divide(Complex comp2) {

double real1 = this.getRealPart();

double real2 = comp2.getRealPart();

double imaginary1 = this.getRealPart();

double imaginary2 = comp2.getRealPart();

return new Complex(real1 / real2, imaginary1 / imaginary2);

}

public String toString() {

String result;

result = realPart + " + " + imaginaryPart + "i";

return result;

}
