Answer:

weight1 = float(input("Enter the weight of first package: "))

price1 = float(input("Enter the price of first package: "))

weight2 = float(input("Enter the weight of second package: "))

price2 = float(input("Enter the price of second package: "))

if weight1 > 0 and price1 > 0 and weight2 > 0 and price2 > 0:

   unit_cost1 = price1 / weight1

   unit_cost2 = price2 / weight2

   if unit_cost1 < unit_cost2:

       print("Package 1 has a better price.")

   else:

       print("Package 2 has a better price.")

else:

   print("All the entered values must be positive!")

Explanation:

*The code is in Python.

Ask the user to enter the weight and the price of the packages

Check if the all the values are greater than 0. If they are, calculate the unit price of the packages, divide the prices by weights. Then, compare the unit prices. The package with a smaller unit price has a better price.

If all the entered values are not greater than 0, print a warning message

Answer:

a. starting balance

Explanation:

A program that calculates the current balance of a savings should ask the user for the starting balance and then ask for the annual interest rate. A loop should then iterate once for every month of the savings period in order to perform other tasks such as asking the user for the total amount deposited into the account, the total amount withdrawn from the account, and calculate the interest rate. The program will then proceed to display the result at the end of the savings period.

D) CVS

Explanation:

A CVS file saves a workbook as a comma-delimited text file for use on another windows operating system. It ensures that line breaks, tab characters and other characteristics are interpreted correctly.

A CVS file stands for Comma Separated Value file, which basically allows the data to be saved in tabular format. However they differ from other spreadsheet file types because you can only have a single sheet in a file. Moreover, you cannot save cell, column or row in it.

def to_pig_latin(word):

   new_word = word[1:] + word[0] + "ay"

   return new_word

print(to_pig_latin("hello"))

print(to_pig_latin("latin"))

Explanation:

Create a function called to_pig_latin that takes one parameter, word

Inside the function, create a new_word variable and set it to the characters that are between the second character and the last character (both included) of the word (use slicing) + first character of the word + "ay". Then, return the new_word.

Call the to_pig_latin function twice, first pass the "hello" as parameter, and then pass the "latin" as parameter

Brute force is  technique that is used for cracking password

In this case the system uses only three characters(0-9). By applying Brute force attack in "hit and try" manner we easily crack the password.

Explanation:

Solution

There are a wide variety of password cracking mechanisms.Brute force is one of the popular password cracking technique.Brute force attack is generally used to crack small passwords.

In the given example the system uses only three characters(0-9).By using Brute force attack in "hit and try" manner we easily crack the password.There are only 10 possible passwords for this type of system.Because we can arrange 0-9 only in 10 ways.But for Systems with long passwords it is difficult to find it in hit and try manner.But instead of having plain password each password have a random salt value.

In a system of 32 bit salt value there are 2^32 different key values.

By increasing the salt value from 32 bits to 64 bits there are 2^64 different key values.It increases the time taken to crack a password for an attacker.so by changing salt value from 32 to 64 bits will make it more harder for the adversary's attack to be successful.

Answer:

B. Partial Copy Sandbox

C. Full Sandbox

D. Developer k Pro Sandbox

Explanation:

In this scenario Universal containers wants to implement a service cloud and test with real Sales Cloud data.

Service cloud is defined a system that allows automation of various customer service functions. It can listen to customers via different social media platforms and direct customers to agents that can solve their problems.

Sandbox is a testing environment that is isolated and allows for running of programs without affecting the application.

To test service cloud implementation with real data we use the following 3 sandboxes:

- Partial copy sandbox: copies only relevant data to test configurations with real data.

- Full Sandbox: makes a replica of data by copying all data such as attachments, metadata, and object records.

- Developer K pro sandbox: is used by developers to test software in an isolated environment and can use large data sets. It includes configuration data (metadata)

Explanation:

So it sounds we need to make a diamond shape out of asterisks like this:

  *

 ***

*****

*******

*****

 ***

  *

There are 7 rows and each row has up to 7 characters. The pattern is also symmetrical which makes it easier. Before writing any code, let's figure out how we are going to determine the correct amount of spaces we need to print. There are a lot of ways to do this, but I'll just show one. Let's call the 4th row y=0. Above that we have row 3 which would be y=-1, and below is row 5 which is y=1. With 7 rows, we have y=-3 through y=3. The absolute value of the y value is how many spaces we need.

To determine the number of stars, we just double the number of spaces, then subtract this number from 7. This is because we can imagine that the same amount of spaces that are printed in front of the stars are also after the stars. We don't actually have to print the second set of spaces since it is just white space, but the maximum number of characters in a row is 7, and this formula will always make sure we have 7.

I hope this helps. If you need help understanding any part of the code, jsut let me know.

   elif percent > 50:

       resps.append("Watch out for clouds!")

   else:

       resps.append("Nice day!")

for r in resps:    

   print(r)

Explanation:

*The code is in Python.

Create an empty list called resps

Initialize a list called percent_rain with some values

Create a for loop that iterates through the percent_rain. Check each value in the percent_rain and add the required strings to the resps using append method

Create another for loop that iterates throgh the resps and print the values so that you can see if your program is correct or not

Answer:

resps = []

for i in percent_rain:

   if i > 90:

       resps.append("Bring an umbrella.")

   elif i >80:

       resps.append("Good for the flowers?")

   else:

       i = 0

       while i<num_cycles:

           print (i+1,": Lather and rinse.")

           i = i + 1

       print('Done.')

user_cycles = int(input())

shampoo_instructions(user_cycles)

Explanation:

def shampoo_instructions(num_cycles): #def function with loop

   if num_cycles < 1:  #using 1st if statement

       print('Too few.')

   elif num_cycles > 4:

       print ('Too many.')

   else:

       i = 0

       while i<num_cycles:

           print (i+1,": Lather and rinse.")

           i = i + 1

       print('Done.')

user_cycles = int(input())

Answer:

D. [1] 1 [13, 3, 2, 8, 21, 5]

Explanation:

Using a quicksort with 1 as the pivot point, elements less than 1 will be sorted to the left of 1 and the other elements are greater than one will be sorted to the right of 1. The order doesn't matter. So we sort [1] to the left of 1 and [13, 3, 2, 8, 21, 5] to the right of 1. So, D. [1] 1 [13, 3, 2, 8, 21, 5] is the valid partition.

There's nothing wrong with the question you posted except that it's not well presented or arranged.

When properly formatted, the program will be error free and it'll run properly.

The programming language used in the question is Java programming lamguage.

in java, the sign ";" signifies the end of each line and lines that begins with // represent comments. Using this understanding of end of lines and comments, the formatted code goes thus

import java.util.Scanner;  

public class Arraysum {  

public static void main(String[] args) {  

Scanner scnr = new Scanner(System.in);  

final int NUM_ELEMENTS = 8;

// Number of elements  

int[] userVals = new int[NUM_ELEMENTS];  

// User numbers  

int i = 0;  

// Loop index  

int sumVal = 0;  

// For computing sum  

// Prompt user to populate array  

System.out.println("Enter " + NUM_ELEMENTS + " integer values...");  

for (i = 0; i < NUM_ELEMENTS; ++i) {  

System.out.print("Value: ");  

userVals[i] = scnr.nextInt();  

}  

// Determine sum  

sumVal = 0;

for (i = 0; i < NUM_ELEMENTS; ++i)

{

sumVal = sumVal + userVals[i];

}

System.out.println("Sum: " + sumVal); return;

}

Answer:

The correct answer is option A

Explanation:

Solution

Recall that:

From the question stated,the following segments of code that should be used in replacing the /* missing code */ so that the value 20 will be printed is given below:

Android a = new Android(x);

a.setServoCount(y);

System.out.println(a.getServoCount());

The right option to be used here is A.

Based on the information given, the code segments that's appropriate will be A  Android a = new Android(x);

From the question stated, it was inferred that we should get the segments of code that should be used in replacing the /* missing code */ so that the value 20 will be printed.

This will be:

Android a = new Android(x);

a.setServoCount(y);

System.out.println(a.getServoCount());

In conclusion, the correct option is A.
