Answer:
3962.96 is the radius
Step-by-step explanation:
r=C
2π=24900
2·π≈3962.95808
Hope this helps. I'm really sorry. We all struggling out here. We can do it!!
-10x=-12x + 21 + 11
-10x= -12 + 32
-10x + 12x = 32
2x = 32
X = 32/2
Since it is not mentioned in the problem, we will assume that repeating of number is allowed.
For the first wheel, you have 10 possible digits.
For the second wheel, you have 10 possible digits.
For the third wheel, you have 10 possible digits.
10 x 10 x 10 = 1000
The probability that someone randomly guesses the correct combination in his first attempt is 1/1000.
If this was without repeat, then
10*9*8 = 720
The probability that someone randomly guesses the correct combination in his first attempt is 1/720.
Answer:
a. k = n - 1 b. 15 c. 112
Step-by-step explanation:
I can answer a. b. and c. for you!
For a. let's say that the variable k means keys. And n means bits.
Since Millie can collect one less keys than there are bits, the equation is....
*See top*
For b. if Antonio has a 16-bit system, by looking at our equation we know that k = n - 1.
So, if n = 16, k = 15
For c. if each byte equals 8 bits, and there are 14 bytes, then the amount of bits would be 8 x 14.
8 x 14 = 112
