An atm personal identification number (pin) consists of four digits, each a 0, 1, 2, . . 8, or 9, in succession. a. how many different possible pins are there if there are no restrictions on the choice of digits?

An atm personal identification number (pin) consists of four digits, each a 0, 1, 2, . . . 8, or 9, in succession.

a. How many different possible pins are there if there are no restrictions on the choice of digits?

Solution: The are total 10 numbers between 0 and 9.

Also there are no restrictions on the choice of digits. Therefore, the possible number of different PINs is:

Therefore, there are 10,000 different possibles PINs.

what does muffins have to do with anything?

step-by-step explanation:

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
