Each digit can be 0-9 ( 10 numbers)
there are 9 numbers in a social security number
multiply 10 nine times:
10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 = 1,000,000,000 ( 1 billion) possibilities.
the restriction is it can't be all zeros so subtract 1 from the total
1,000,000,000 - 1 = 999,999,999 combinations
Answer:
Left 3 units and up 6 units
Step-by-step explanation:
Answer:
z=34
Step-by-step explanation:
2 + 8 - z = -24
add
10-z = -24
subtract 10 from each side
10-z-10 = -24-10
-z = -34
multiply by -1
-1*-z = -34 * -1
z = 34
Answer:
There are a total of 
functions.
Step-by-step explanation:
In order to define an injective monotone function from [3] to [6] we need to select 3 different values fromm {1,2,3,4,5,6} and assign the smallest one of them to 1, asign the intermediate value to 2 and the largest value to 3. That way the function is monotone and it satisfies what the problem asks.
The total way of selecting injective monotone functions is, therefore, the total amount of ways to pick 3 elements from a set of 6. That number is the combinatorial number of 6 with 3, in other words
Circumference = PI * diameter
diameter = Circumference / PI
diameter = 40.82 / 3.14159265
diameter =
