(a) 676000

(b) 468000

Step-by-step explanation:

We know that the total number of digits in the number system from 0 to 9= 10

The total number of letters in English alphabet (Only upper case) from A to Z = 26

Given : In a certain state, license plates cach consist of 2 letters followed by 3 digits.

(a) If repetition is allowed , then the total number of different license plates there are :-

hence, the number of different license plates = 676000

(b)  If repetition is not allowed , then the total number of different license plates there are :-

Hence, the number of  different license plates are there that have no repeated letters or digits=468000

ian gone lie this got me confused

step-by-step explanation:

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
