Answer:
The correct answer is:
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,
= 
= 
The jobs per hour will be:
⇒ 

(b)
⇒ Service rate = jobs per hour
then,
μ = 
= 
For this case we convert the mixed numbers to fractions:
Dwight:
Mike:
It is observed, that in fact, Mike takes more time to travel the road.
We subtract to know how much more time it takes Mike:

So, Mike takes
hours more than Dwight to walk the road.
Answer:
Mike takes
hours longer than Dwight to walk the road.
Answer:
13 m
Step-by-step explanation:
<u>The distance x is:</u>
x = √12² + (13 -8)² = √144 + 25 = √169 = 13 m
