Answer:
There is a probability that the correct password is found on the sixth try.
Step-by-step explanation:
We have n passwords, only 1 is correct.
So,
Since a password is put back with other, at each try, we have that:
The probability that a password is correct is
The probability that a password is incorrect is .
There are 6 tries.
We want the first five to be wrong. So each one of the first five tries has a probability of . So, for the first five tries, the probability of getting the desired outcome is .
We want to get it right at the sixth try. The probability of sixth try being correct is .
So, the probability that the first five tries are wrong AND the sixth is correct is:
There is a probability that the correct password is found on the sixth try.

The hourly wage increase each employee receives each year depends on their number of years of service. Every three years of service means an increase of $0.50 per hour. So, employees that have been with the company for less than three years can expect to receive an increase of $0.50 per hour. Employees that have been with the company for at least three years, but less than six years can expect an increase of $1.00 per hour. Employees that have been with the company for at six years, but less than nine years, receive an increase of $1.50 per hour. And, employees of at least nine years, but less than twelve years receive an increase of $2.00 per hour.
Choose a function to represent this scenario
Answer:
49/4
Step-by-step explanation:
x^2 + 7x = 4
Take the coefficient of x
7
Divide by 2
7/2
Square it
(7/2) ^2 = 49/4
Add this to each side
x^2 + 7x +49/4= 4+49/4
