QUESTION 3 If one wanted to find the probability of 10 customer arrivals in an hour at a service station, one would generally use the . a. hypergeometric probability distribution b. Poisson probability distribution c. exponential probability distribution d. binomial probability distribution

b. Poisson probability distribution

Step-by-step explanation:

A Poisson probability distribution is a discrete probability distribution that expresses the probability of a given number of events occurring in a fixed interval. The mean of successful outcomes (u) that occur in an interval is constant and known. Each event is independent of all other events.

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

320ft

step-by-step explanation:

120 divided by 3 equals 40

40 times 4=160

160 times 2=320
