Answer:
The probability of a correct guess on the first try is 0.024%.
Since a thief steals an atm card and must randomly guess the correct four -digit pin code from a 8 -key keypad, and repetition of digits is allowed, to determine what is the probability of a correct guess on the first try the following calculation must be performed:
8 x 8 x 8 x 8 = X
8 ^ 4 = X
4096 = X
1/4096 = X
0.000244140625 = X
0.000244140625 x 100 = 0.024%
Therefore, the probability of a correct guess on the first try is 0.024%
Step-by-step explanation:
(f - g)(x) = (3x² + 1) - (1 - x)
= 3x² - x
OR
= x(3x - 1)
Answer:
For this problem we are assuming that the confidence level is 99% or 0.99, then the significance level would be

Answer:
it is basically a rise, the 2 is positive so goes up from left to right, then a fall, bc -2 goes down from left to right
Step-by-step explanation:
Answer:
The dots shown on the graph have a rise of 6 and a run of 4 (so 6/4)
This fraction can be reduced so your answer is 3/2
