I have to solve the system of linear equations by elimination. i also have to check my solution.

Travka [436]

Answer:

$x=1$ , $y=6$

Step-by-step explanation:

Give.

$x+2y=13$ ----------(1)

$-x+y=5$ ------------(2)

Solve this linear equation by elimination method.

Add equation 1 and 2

$x+2y=13$

$-x+y=5$

-----------------------------

$0+3y=18$

$3y=18$

$y=\frac{18}{3} \\y=6$

Put y value in equation 2

$-x+6=5$

$-x=5-6$

$-x=-1$

$x=1$

$x=1$ , $y=6$

The secretary in Exercises 2.121 and 3.16 was given n computer passwords and tries the passwords at random. Exactly one of the p

Vlada [557]

Answer:

There is a $\frac{(n-1)^{5}}{n^{6}}$ 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 $\frac{1}{n}$

The probability that a password is incorrect is $\frac{n-1}{n}$ .

There are 6 tries.

We want the first five to be wrong. So each one of the first five tries has a probability of $\frac{n-1}{n}$ . So, for the first five tries, the probability of getting the desired outcome is $\frac{(n-1)^{5}}{n^{5}}$ .

We want to get it right at the sixth try. The probability of sixth try being correct is $\frac{1}{n}$ .

So, the probability that the first five tries are wrong AND the sixth is correct is:

$P = \frac{(n-1)^{5}}{n^{5}}\frac{1}{n} = \frac{(n-1)^{5}}{n^{6}}$

There is a $\frac{(n-1)^{5}}{n^{6}}$ probability that the correct password is found on the sixth try.
