X = 12 is a vertical line. a parallel line will also have to be a vertical line, and a perpendicular one will, in this case, be a horizontal line.
the slope of x = 12 is undefined, because it fails the vertical line test. a horizontal line, however, passes the vertical line test -- but there is no increase or decrease. the slope of a horizontal line is 0.
so with that information in mind (the slope of a vertical line is undefined, the slope of a horizontal line is 0), you can easily state that a line parallel to x = 12 will have an undefined slope, and also that a line perpendicular to x = 12 will have a slope of 0.

Answer:
There is a 3.33% probability that exactly two such busses arrive within 3 minutes of each other.
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given time interval.
What is the probability that exactly two such busses arrive within 3 minutes of each other
The mean is one bus each 10 minutes. So for 3 minutes, the mean is 3/10 = 0.3 buses. So we use
This probability is P(X = 2).
There is a 3.33% probability that exactly two such busses arrive within 3 minutes of each other.
Answer:
<h2>4 and 8</h2>
Step-by-step explanation:
4 and 8 are corresponding angles as they form at parallel lines cut by a transversal.
4 and 3 are supplementary angles (they both add up to 180°).
4 and 1 are vertically opposite angles and are equal to each other.
<u>From the above explanations, only 4 and 8 are corresponding angles. </u>

Answer:
$ 1.2
Step-by-step explanation:
The first thing is to define the expected value of the ticket that would be the sum of the value for all event probabilities.
That is, if you buy 1 ticket, for each participant the probabilities are:
1. 1/1000 to get a $ 1,200 item
2. 999/1000 to get nothing ($ 0).
That is to say:
(1/1000) * $ 1200 + (999/1000) * $ 0 = (1/1000) * $ 1200 = $ 1.2
Therefore, the expected value is $ 1.2, this means that in reality each participant pays $ 0.8 more than the ticket is worth
