Nite time inn has a toll-free telephone number so that customers can call at any time to make a reservation. a typical call takes about 4 minutes to complete, and the time required follows an exponential distribution.
find the probability that a call takes:
(a) 3 minutes or less.
(b) 4 minutes or less.
(c) 5 minutes or less.
(d) longer than 5 minutes.

Step-by-step explanation:

Let X be the time for any customer to call at any time to make reservation in Nite Time Inn.

Given that X is exponential with mean = 4 minutes

We are to find the probability

(a) 3 minutes or less.

=

(b) 4 minutes or less.

(c) 5 minutes or less.

(d) longer than 5 minutes.

=1-P(X≤5) = 0.2865

answer: it is 1: 47 pm

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.
