we are given
$85 $240 $120 $60 $315 $190 $145 $105 $285 $260 $95 $215 $235 $175 $155
Firstly, we will arrange it in ascending order
we get
$60 $85 $95 $105 $120 $145 $155 $175 $190 $215 $235 $240 $260 $285 $315
total counts =15
place of 105 is 4
now, we can find percentile
so, the percentile of the bid value $105 is 26.667%...........Answer

Step-by-step explanation:
and,
represents perpendicular lines.
Two lines are perpendicular when product of their slopes = -1
In, y =½x+4
m1 = ½
In y = -2x -3
m2 = -2
Now, m1× m2 = ½× (-2) = -1
Answer:
The Poisson distribution uses the shape parameter denoted by <em>λ</em>.
Step-by-step explanation:
A Poisson distribution is used to describe the distribution of the number of events that take place in a fixed interval of time.
For instance, number of customers arriving at a bank in an hour or the number of typos encountered in a book every 50 pages.
The Poisson distribution uses the shape parameter to compute the probabilities of different events.
The shape parameter is defined as the average number of occurrence in a given time interval. It is usually denoted by <em>λ</em>.
The probability mass function of a Poisson distribution is:
