Problem 15-7 (Algorithmic) Speedy Oil provides a single-server automobile oil change and lubrication service. Customers provide

rodikova [14]

Answer: There are 4 average cars in the system.

Step-by-step explanation:

Since we have given that

Arrival rate = λ = 4 cars per hour

Service rate = μ = 5 cars per hour

We need to find the average number of cars in the system.

So, Average number of cars would be

$L_q=\dfrac{\lambda^2}{\mu(\mu-\lambda)}\\\\L_q=\dfrac{4^2}{5(5-4)}\\\\L_q=\dfrac{16}{5}\\\\L_q=3.2$

So, it becomes,

$L=L_q=\dfrac{\lambda}{\mu}\\\\L=3.2+\dfrac{4}{5}\\\\L=3.2+0.8\\\\L=4$

Hence, there are 4 average cars in the system.

A plot of land has an area of 1,089,000 square feet.The conversion factors between different area measures are shown below.27,87

IgorC [24]

Part A) 24.79 acres

1) Since that plot has an area of

$1,089,000ft^2=1.08\times10^6ft^2$

And the number of units must be between 10 and 10² units.

Part A)

$\begin{gathered} 27,878,400ft^2=2.78784\times10^7ft^2=1m^2 \\ 43560ft^2\text{ =4.356 }\times10^4ft^2\text{ = 1 acre} \end{gathered}$

2) Let's convert them to the apparently plausible units, see if it fits within the given interval.

$\begin{gathered} \frac{1.08\times10^6}{4.356\times10^4}=24.79\text{ acres} \\ \frac{1.08\times10^6}{2.78784\times10^7}=0.03m^{2} \end{gathered}$

We can see that 0.03 m² does not belong to the given interval.

3) Hence, the answer is 24.79 acres.

The stamp is 71 millimeters wide. How many meters wide is the stamp?

Mrrafil [7]

<h3>♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>

➷ 1 meter is 1000 millimeters

Therefore, we have to divide by 1000

71/1000 = 0.071

Therefore, your answer is option A.
