Answer:
59049 digits
Step-by-step explanation:
Given
Digits = 0 to 9
Required
Determine number of 5 digit pins that must not contain 0
There are 10 digits.
Since the pin must not contain 0, there are 9 digits left to select from.
The question didn't state that a digit can not be repeated, so I'll assume that repetition of digit is allowed.
The 1st digit of the 5 could be any of the 9 digits
The 2nd could be any of the 9 digits
The 3rd could be any of the 9 digits
The 4th could be any of the 9 digits
The 5th could be any of the 9 digits
Hence, number of selection is calculated as this:
Selection = 9 * 9 * 9 * 9 * 9
Selection = 59049
(70x10)+(6x1)+(4x1/10)+(2x1/100)+(9x1/1000)
5+5x=Larys
9+4x=Boardwalk
5+5x=9+4x
-4x -4x
5+x=9
-5 -5
x=4
If you rent a bike for four hours the cost will be the same at both places
Prime numbers are numbers that can be divided without a remainder. So 2181 is divisible by 3 and 727 and there is no remainder.
