Explain why 2-81273-05213-8 is an invalid upc number.
step 1: verify the last digit of the code. (10 points)
step 2: identify what the last digit should be in order to make it a valid code.

Part 1) Is not a valid code

Part 2) The last digit should be 6 in order to make it a valid code

Step-by-step explanation:

we have

2-81273-05213-8

we know that

The last number is the check digit (8)

Verify the UPC number

step 1

Sum the digits in the odd positions, starting at the left

so

2+1+7+0+2+3=15

step 2

Multiply the answer in step 1 by 3

15(3)=45

step 3

Sum the numbers in the even positions, ignoring the last (12th) digit because that is the check digit that you are verifying

Do not multiply this number by 3.

8+2+3+5+1=19

step 4

Add the results from steps 2 and 3

45+19=64

step 5

Subtract the number in step 4 from the next higher multiple of 10. In this example, the next multiple of 10 after 64 is 70, so subtract 64 from 70:

70-64=6

This number is not equal to the check digit (8)

therefore

Is not a valid code

The last digit should be 6 in order to make it a valid code

step-by-step explanation:

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
