The snippets of code below each return a Boolean value. Select all codes that return a value of True. a. b. 1+2-3==0 O c. bool('False') O d. True or False O e. Of. not 3>2 19 and False bool(sum([1,2,-3]))
Given two integers, a and b, return true if a can be divided evenly by b. Return false otherwise. Examples divides Evenly (98, 7) true // 98/7 = 14 → divides Evenly (85, 4) false // 85/4 = 21.25 → Notes a will always be greater than or equal to b.

Write a program that converts U.S. Dollar Amounts to different Cryptocurrencies by multiplying US Dollar amounts times conversion factors stored in named constants. Ask the user to enter the amount of money in U.S. Currency, then display the output of the conversions to the different cryptocurrencies listed below. The following conversion rates must be stored as named constants: 1 US Dollar = 0.00002306 Bitcoin (BTC)1 1 US Dollar = 0.01122814 Ethereum Classic (ETC)1 1 US Dollar = 2.07961078 Dogecoin (DOGE)1 1 US Dollar = 0.48910811 Cardano (ADA)1 Format your currency amounts in fixed point notation with two decimal places of precision, and be sure that the decimal point is always displayed.
Convert the decimal (base 10) number 63 to a binary (base 2) number that has only the digits '0' and '1'. Binary number: (For example, the decimal number 16 is the same as the binary number 10000; the decimal number 13 is the same as the binary number 1101.)
The following binary sequences are stored in two distinct 16-bit memory locations: Q1 A = 10010001 11000111 B = 01111010 11101000 Hint: You can use calculators/tools, but you should show the calculation procedure for each case Find both binary and decimal values of Z=A+B if A, B, and Z are all signed a integers. Find both binary and decimal values of Z=A+B if A, B, and Z are two's complement numbers. If A and B are two Boolean vectors (vectors in which every element is TRUE or C FALSE), find the outcome of the following bit-wise logical operation: (A&&B)||(!A&&!B). What would be the data type and the corresponding value of Z=A+B (written d in Python) if A and B represent two ASCII Strings (Find ASCII table in appendix). If A represent the first two bytes (network prefix) and B represents the last e two bytes (host suffix) of a class B IPV4 address, find the corresponding IP address.
The International Standard Book Number (ISBN) is a number that uniquely identifies a book. Publishers can buy or receive ISBNs from the International ISBN Agency. There are two types of ISBNs: ISBN-13 and ISBN-10, which are 10- and 13-digits long, respectively.ISBN-10 has a pattern, where the last digit can be found using the first 9. Additionally, ISBN-10 can also be used to calculate its ISBN-13 equivalent (and vice versa). Write two functions in ISBN.java. The main method is implemented for you so you can test your functions. Instructions on how to run this file to make use of the test.txt file are detailed below. calculateISBN10(int[] isbn) computes the last digit of the ISBN-10 number. The first 9 of the 10 digits of the ISBN will be passed to the function as the parameter isbn integer array of size 10. The last integer in the array will be -1. Your job is to calculate the last digit (called the check digit), and update the last index of the isbn array with the computed…

Write code that prints a random number of lines between 2 and 10 lines inclusive, where each line contains a random number of 'x' characters between 5 and 20 inclusive. For example: xxxxxxx xxxxxxxxxxxxxxxxxx xxxxxxxxxxxx xxxxxx xxxxxxxxxxx xxxxxxxxxxxxxxxx
The parity bit of a sequence of bits is 0 if the number of l's in the sequence is even and 1 otherwise. Еxample: • if the sequence of bits is 1 1 0 1, the parity bit should be 1 (total number of 1-bits is 3 which is odd) • if the sequence of bits is 1 0 1 0, the parity bit should be 0 (total number of 1-bits is 2 which is even) Write a Java program that asks the user to enter the number of bits he has. The program then reads the bits as separate integers. In the end, the program prints the parity bit on the screen. If the use enters a bit value that is neither 0 nor 1, the entry should be discarded and a message displayed as shown in the sample run. Sample run 1: How many bits do you have? 6 Enter 6 bits: 1 1 0 0 1 0 The parity bit is 1 Sample run 2: How many bits do you have? 8 Enter 8 bits: 1 1 1 0 0 0 0 1 The parity bit is 0 Sample run 3: How many bits do you have? 5 Enter 5 bits: 1 1 3 0 1 Incorrect bit value 3 is discarded. The parity bit is 1
A consumer can withdraw up to $500 per day from an ATM. If a customer withdraws more than $300, the service charge is 4%. It tells the consumer of inadequate cash and offers to withdraw the money for a fee of $25.00. The ATM won't let you withdraw money if your account is empty or has a negative balance. If the withdrawal exceeds $500, the ATM informs the customer of the maximum withdrawal amount and refuses the withdrawal. Write an algorithm that allows customers to enter withdrawal amounts. The algorithm then verifies the account balance, debits the customer's account for the amount withdrawn plus any service fees.
