Answer:

n = (-44)/9

Step-by-step explanation:

Solve for n:

n - 2 = 10 n + 42

Subtract 10 n from both sides:

(n - 10 n) - 2 = (10 n - 10 n) + 42

n - 10 n = -9 n:

-9 n - 2 = (10 n - 10 n) + 42

10 n - 10 n = 0:

-9 n - 2 = 42

Add 2 to both sides:

(2 - 2) - 9 n = 2 + 42

2 - 2 = 0:

-9 n = 42 + 2

42 + 2 = 44:

-9 n = 44

Divide both sides of -9 n = 44 by -9:

(-9 n)/(-9) = 44/(-9)

(-9)/(-9) = 1:

n = 44/(-9)

Multiply numerator and denominator of 44/(-9) by -1:

Answer: n = (-44)/9

A box of cookies contains 4 chocolate and 6 butter cookies. Miguel randomly selects a cookie and eats it. Then he randomly selec

laila [671]

Answer:

The probability of the flavor of the second cookie is always going to be dependent on the first one eaten.

Step-by-step explanation:

Since the number of the type of cookies left depends on the first cookie taken out.

This is better explained with an example:

Probability Miguel eats a chocolate cookie is 4/10. The probability he eats a chocolate or butter cookie after that is 3/9 and 6/9 respectively. This is because there are now only 3 chocolate cookies left and still 6 butter cookies left.
In another case, Miguel gets a butter cookie on the first try with the probability of 6/10. The cookies left are now 4 chocolate and 5 butter cookies. The probability of the next cookie being chocolate or butter is now 4/9 and 5/9 respectively.

The two scenarios give us different probabilities for the second cookie. This means that the probability of the second cookie depends on the first cookie eaten.

x:5.25x

Step-by-step explanation:

Basically, you do 42 divided by 8 to get the cost of $5.25 which is the cost of one ticket. Then you multiply that for each number of ticket.
