Let f(x)= 3x2 +5 and g(x) = - 5x + 3. Find the following.
(f-g)(-4)
(f-9)(-4)=

No. of Persons= 16

Step-by-step explanation:

There was a one phone line

Average no of people calling = 60 in one hour

% of all callers at most can get busy signal

Probability < 0.6

Probability for less than 1 person on hold = 0.2642

No of persons = 0.2642(60)

= 15.852 or 16

16 persons in hour the company is able to put on hold
