Answer:
D.
Step-by-step explanation:
we are given
we can use standard equation of hyperbola
where
center=(h,k)
center at origin
so, h=0 and k=0
vertex is
we can use formula
vertices: (h, k + a)
we get
we can plug k=0
now, we can plug these values
now, we are given it passes through
so, we have
we can plug these values and then we can solve for b
and we get
we can solve for b
and we get
now, we can plug these values
we can simplify it
and we get

Hope that helps. If you need me to explain how I got my answer I will provide a picture.
Using the Poisson distribution, the probability of observing exactly three accidents on this stretch of road next month is given by:
b) 0.052.
<h3>What is the Poisson distribution?</h3>
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by:
The parameters are:
- x is the number of successes
- e = 2.71828 is the Euler number
- is the mean in the given interval.
Researching this problem on the internet, the mean is given by:
.
The probability of observing exactly three accidents on this stretch of road next month is P(X = 3), hence:
Hence option B is correct.
