Answer:

a. 2x+4y=100

b. 2 questions

Step-by-step explanation:

For a, you can write out hat equation, which can test if a specific combination will work, and once you have one variable, you can solve another

For b, you can plug 24 into the equation

2x+4(24)=100

2x+96=100

2x=4

x=2

5x+2y=24 and 8x+2y=30
larisa86 [58]

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

To support National Heart Week, the Heart Association plans to install a free blood pressure testing booth in El Con Mall for th
worty [1.4K]

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
