Answer:
$185 = ($35.25 * P) + ($7.50 * r)
Step-by-step explanation:
If the total that the customer paid was $185 this means that the equation must equal $185. The equation itself must be the number of gallons of exterior paint (P) that the customer ordered multiplied by the price per gallon ($36.25), which is then added to the product of the number of rollers the customer ordered (r) and the price per roller ($7.50). This together would form the following equation...
$185 = ($35.25 * P) + ($7.50 * r)

√160 = √16 *√10 = 4√10 ;
-4 * * 4√10 = -16√10 ;
which is: Answer choice: [C]: " -16√10 " .

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
