The Poisson distribution defines the probability of k discrete and independent events occurring in a given time interval.
If λ = the average number of event occurring within the given interval, then
For the given problem,
λ = 6.5, average number of tickets per day.
k = 6, the required number of tickets per day
The Poisson distribution is
The distribution is graphed as shown below.
Answer:
The mean is λ = 6.5 tickets per day, and it represents the expected number of tickets written per day.
The required value of k = 6 is less than the expected value, therefore the department's revenue target is met on an average basis.
Given:
A quadrilateral QRST.
To find:
The coordinates of Q' after the transformation of .
Solution:
From the given figure, it is clear that
means the figure QRST first reflected across the x-axis, then translated by .
Figure QRST reflected across the x-axis, then
After that, it is translated by .
Therefore, the coordinates of Q' are (0,-1).
Note: All options are incorrect.
Angle A would be anything that Angle B is. If the angles are vertical then they are always congruent.
