Answer:
x = 2
y = 7
Step-by-step explanation:
5x+2y=24 -------------->equ 1
8x+2y=30 -----------> equ 2
equ 1 - equ 2 =====> -3x = - 6
x = -6 / -3 = 2
x = 2
Put x = 2 in equ 1,
5*2 + 2y = 24
10 + 2y = 24
2y = 24 - 10
2y = 14
y = 14/2
y = 7

Answer:
(a) Average number expected = 13.07 people
(b) Average number of persons = 14 persons
(c) Average amount of time = 0.9333 hours
(d) Time taken = 1 hour
Step-by-step explanation:
We are informed that the arrivals have a Poisson distribution from an infinite population. On average, 14 persons per hour request a test. Hence,
Arrival rate = λ = 14
Each blood pressure measurement takes 4 minutes. In 1 hour, 60 / 4 = 15 persons are served. Hence,
Service rate = μ = 15
(a) Average number in line = (λ^2) / μ(μ - λ)
= (14^2) / 15(15 - 14)
= 13.07
(b) Average number in system = λ / (μ - λ)
= 14 / (15 - 14)
= 14
(c) Average waiting time = Average number in line / λ
= 13.07 / 14
= 0.9333
(d) Average total time = Average number in system / λ
= 14 / 14
= 1
Answer:
16.5
Step-by-step explanation:
32 - 15.5 = 16.5
Answer:
