Rewriting the left hand side,
csc²t - cost sec t
= (1/sin²t)-(cost)(1/cost)
= 1/sin²t - 1
= 1/sin²t - sin²t/sin²t
= (1-sin²t)/sin²t
= cos²t/sin²t
= cot²t
Answer:
B) 0.1487
Step-by-step explanation:
Let
be the discrete random variable that represents the number of events observed over a given time period. If
follows a Poisson distribution, then the probability of observing
events over the time period is:

Where:

So, the probability that exactly 5 bankruptcies occur next month is:
