Find the x and y intercept of y=7×+5

Help me with this parallelogram please :)

Parallel sides of parallelogram are equal in length

$\\ \sf\longmapsto AD=BC$

$\\ \sf\longmapsto 6x+14=9x-4$

$\\ \sf\longmapsto 9x-6x=14+4$

$\\ \sf\longmapsto 3x=18$

$\\ \sf\longmapsto x=6$

AD=6x+14=6(6)+14=36+14=50

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
