An average of 40 cars per hour arrive to be painted at a single-server GM painting facility. 95% of the cars require 1 minute to

Sindrei [870]

Answer:

2.719 minutes

Step-by-step explanation:

Step 1 :

We have to consider using the M/G/I /GD /∞/∞ Queuing system with the rate of arrival λ and the rate of service μ.

Since average of 40 cars arrive every hour at the painting facility, it follows that:

Arrival rate λ = 40cars /hour

= 40/60 cars/hour

=2/3 cars/hour

More, we were told that 95% of the cars require 1 minute to paint, 5% must be painted twice and require 2.5 minutes to paint, therefore, the average time to paint a car is given by

95/100x1 + 5/100 x 2.5 = 19/20 + 1/8 = 43/40min

It follows that:

Service rates μ = 40/43cars/min

David y Almudena tienen entre los dos 225 euros. Calcula cuánto dinero tiene cada uno si Almudena posee 75 euros más que David.

Misha Larkins [42]

David and Almudena have between the two 225 euros. Calculate how much money each has if Almudena has 75 euros more than David.

For this case we propose a system of equations:

x: Let the variable that represents Almudena's amount of money

y: Let the variable that represents David's amount of money

According to the statement we have:

$x + y = 225\\y + 75 = x$

Substituting the second equation into the first:

$y + 75 + y = 225\\2y + 75 = 225\\2y = 225-75\\2y = 150\\y = \frac {150} {2}\\y = 75$

We find the value of the variable x:

$x = 75 + 75 = 150$

Almudena has 150 euros

David has 75 euros

Answer:

Almudena has 150 euros

David has 75 euros
