Answer:
(a) 27 extension lines
(b) 0.9000
(c) 30.0000
Step-by-step explanation:
Number of representatives=2, number of extension lines=2, average calls each representative can accommodate per hour = 15 calls, arrival rate per hour = 30 calls
(a) 90% of the arrival rate = 0.09 × 30 = 27 calls
To handle 27 calls immediately, 27 extension lines should be used
(b) Probability is given by number of possible outcomes ÷ number of total outcomes
Number of possible outcomes = 27, number of total outcomes = 30
Probability (call will receive busy signal) = 27/30 = 0.9000
(c) For one extension line, numbers of calls to receive busy signal = 30 - 15 = 15.0000 calls
Number of calls to receive busy signal for the current telephone system with two extension lines = 2 × 15.0000 = 30.000 calls
Answer: The answer is 20.
Step-by-step explanation: Given that the smallest angle of rotation for a regular hexagon is 18°. We are to find the number of sides of the polygon.
Since the polygon is regular, so all its sides and angles are equal. Hence, each angle of the polygon is 18°.
We know that the number of sides of the regular polygon with each angle 'α'
is given by
Here, α = 18°, then we have
Thus, the number of sides will be 20.
Step-by-step explanation:
The answer needs to be in ounces so convert the pints and cups to ounces to solve. There are 16 ounces in a pint and 8 ounces in a cup. 2 pints would be 2 X 16 ounces and 3 cups would be 3 X 8 ounces.

Answer:
2 sqrt(15)
Step-by-step explanation:
Using the secant tangent formula
(whole secant) x (external part) = (tangent)^2
(5+7) * 5 = x^2
12*5 = x^2
60 = x^2
Taking the square root
sqrt(60) = sqrt(x^2)
sqrt(4*15) = x
2 sqrt(15) =x
