Line DG is 24.5. So DO +DG= 24.5

(3x+4) + (5x-1.5) =24.5 then combine like terms.

8x+2.5=24.5

-2.5. -2.5

8x = 22 then divide both sides by 8

X=2.75.

To find DO and OG plug in the value of X and solve

3(2.75) +4

8.25+4 = 12.25

5(2.75) -1.5

13.75 - 1.5= 12.25

The Robotics Manufacturing Company operates an equipment repair business where emergency jobs arrive randomly at the rate of thr

cluponka [151]

Answer:

The correct answer is:

$\lambda=0.375 \ jobs \ per \ hour$
$\mu=0.5 \ jobs \ per \ hour$

Step-by-step explanation:

The given values are:

Service time varies,

Repair time = 2 hours

Standard deviation = 1.5 hours

Robotics uses per hour cost,

= $35

Company's cost per hour,

= $28

(a)

⇒ Arrival rate = Jobs per hours

then,

= $\frac{8 \ hours}{3 \ jobs}$

= $2.666 \ hours \ per \ job$

The jobs per hour will be:

⇒ $\lambda=\frac{1}{2.666}$

$=0.375$

(b)

⇒ Service rate = jobs per hour

then,

μ = $\frac{1 \ repair \ job}{2 \ hours}$

= $0.5 \ jobs$
