Daniel [21]

Answer:

#include <iostream>

using namespace std;

class BankAccount {

string name = name;

double balance = balance;

BankAccount( string name, double balance ) {

string name = name;

double balance = balance;

return 0;

}

string getName( ){

return name;

}

double getbalance( ) {

return balance;

void setName( string username){

name = username;

}

void setbalance( double newBalance){

balance = newBalance;

}

int main( ) {

BankAccount user1(John, 0.0);

BankAccount user2(Jane, 0.0);

user1.setbalance( 2300.00)

user2.setbalance( 4300.00)

cout << user1.getname() << user1.getbalance();

}

Explanation:

The C source code above using a class to create a data structure of a bank account user name and balance. The attribute name and balance are private to the class and can be retrieved and modified through the get and set methods.

Papessa [141]

Answer:

Explanation:

Sorry it is in Java, though you can covert it using converter

public class Exercise {

public static void main(String[] args) {

Scanner input = new Scanner(System.in);

int positives = 0; // Count the number of positive numbers

int negatives = 0; // Count the number of negative numbers

int count = 0; // Count all numbers

double total = 0; // Accumulate a totol

// Promopt the user to enter an integer or 0 to exit

System.out.print("Enter an integer, the input ends if it is 0: ");

int number = input.nextInt();

if (number == 0) { // Test for sentinel value

System.out.println("No numbers are entered except 0");

System.exit(1);

}

while (number != 0) {// Test for sentinel value

if (number > 0)

positives++; // Increase positives

else

negatives++; // Increase negatives

total += number; // Accumulate total

count++; // Increase the count

number = input.nextInt();

}

// Calculate the average

double average = total / count;

// Display results

System.out.println(

"The number of positive is " + positives +

"\nThe number of negatives is " + negatives +

"\nThe total is total " + total +

"\nThe average is " + average);

Fifty-three percent of U.S households have a personal computer. In a random sample of 250 households, what is the probability th

aleksley [76]

Answer:

The correct Answer is 0.0571

Explanation:

53% of U.S. households have a PCs.

So, P(Having personal computer) = p = 0.53

Sample size(n) = 250

np(1-p) = 250 * 0.53 * (1 - 0.53) = 62.275 > 10

So, we can just estimate binomial distribution to normal distribution

Mean of proportion(p) = 0.53

Standard error of proportion(SE) = $\sqrt{\frac{p(1-p)}{n} }$ = $\sqrt{\frac{0.53(1-0.53)}{250} }$ = 0.0316

For x = 120, sample proportion(p) = $\frac{x}{n}$ = $\frac{120}{250}$ = 0.48

So, likelihood that fewer than 120 have a PC

= P(x < 120)

= P( p^ < 0.48 )

= P(z < $\frac{0.48-0.53}{0.0316}$ ) (z= $\frac{p^-p}{SE}$ )

= P(z < -1.58)

= 0.0571 ( From normal table )
