Hello hello!
Solving this is simple, just remember the vertical angles theorem. Due to this theorem, you are able to conclude that x+40 and 60 are equal in terms of their angle measure. This means that to solve this, we need to set both sides equal to each other and solve for x, and plug it in!
STEP ONE: 60 = x + 40
DO: Subtract 40 from both sides.
STEP TWO: 20 = x
DO: You've answered the question!
ANSWER: x = 20Ответ:
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
