C PROGRAM A barcode scanner for Universal Product Codes (UPCs) verifies the 12-digit code scanned by comparing the code’s last digit (called a check digit) to its own computation of the check digit from the first 11 digits as follows: 1. Calculate the sum of the digits in the odd-numbered positions (the first, third… eleventh digits) and multiply this sum by 3. 2. Calculate the sum of the digits in the even-numbered positions (the second, fourth… tenth digits) and add...

Outside a home, there is a 7-key keypad numbered 1 through 7. The correct five-digit code will open the garage door. The numbers can be repeated in the code (a) How many codes are possible? (b) What is the probability of entering the correct code on the first try, assuming that the owner doesn't remember the code? (a) The number of possible codes is Type an integer or fraction. Simplify your answer.) (b) The probability that the correct code is...

QUESTION 7 10 points The smallest digit of a number is the uncertain digit. For example the number 3 in the number 2.3 is the uncertain digit. So the number 2.3 is known to within a tenth of a unit (because 3 is in the tenth digit) In adding or subtracting numbers, determine which number has the largest uncertainty and round the result of the addition/subtraction to that digit. Example: 36.7+102.45 -139.15-139.2 The reason: Because the largest udcertainty is in...

Athiel steals an ATM card and must randomly guess the correct three-digit pincode from a 7-key keypad. Repetition of digits is allowed. What is the probability of a correct guess on the first try? The number of possible codes is (Type an Integer or fraction Simplify your answer.) The probability that the correct code is given on the first try is (Type an integer or fraction Simplify your answer)

Introduction: Ten digit ISBN numbers are created so that the first nine digits are information digits and the last digit is a check digit. T his last number helps people notice and correct mistakes that might be made in recording the information digits. The same is true for thirteen digit ISBN numbers. Here is a ten digit ISBN number: 0-13-149498-8. The digit 0 indicates the book is written for English-speaking people. The number 13 and the number 149498 identify the...

Banks issue credit cards with 16 digit numbers. If you've never thought about it before you may not realize it, but there are specific rules for what those numbers can be. For example, the first few digits of the number tell you what kind of card it is - all Visa cards start with 4, MasterCard numbers start with 51 through 55, American Express starts with 34 or 37, etc. Automated systems can use this number to tell which company...

In the US, telephone numbers are 7-digit long. While in general they have some restrictions, for example, they cannot start with 0 or 1, here we assume that all 7-digit sequences are possible, even 0000000. How many phone numbers: start or end with the two identical digits, for example 0012345, 1234511, or 2222222, contain a 5-digit consecutive substring. For example 0034567, 2567892, or 1234567

Write java program to check that a (16-digit) credit card number is valid. A valid credit card number will yield a result divisible by 10 when you: Form the sum of all digits. Add to that sum every second digit, starting with the second digit from the right. Then add the number of digits in the second step that are greater than four. The result should be divisible by 10. For example, consider the number 4012 8888 8888 1881. The...
