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,
= ![\frac{8 \ hours}{3 \ jobs}](https://tex.z-dn.net/?f=%5Cfrac%7B8%20%5C%20hours%7D%7B3%20%5C%20jobs%7D)
= ![2.666 \ hours \ per \ job](https://tex.z-dn.net/?f=2.666%20%5C%20hours%20%5C%20per%20%5C%20job)
The jobs per hour will be:
⇒ ![\lambda=\frac{1}{2.666}](https://tex.z-dn.net/?f=%5Clambda%3D%5Cfrac%7B1%7D%7B2.666%7D)
![=0.375](https://tex.z-dn.net/?f=%3D0.375)
(b)
⇒ Service rate = jobs per hour
then,
μ = ![\frac{1 \ repair \ job}{2 \ hours}](https://tex.z-dn.net/?f=%5Cfrac%7B1%20%5C%20repair%20%5C%20job%7D%7B2%20%5C%20hours%7D)
= ![0.5 \ jobs](https://tex.z-dn.net/?f=0.5%20%5C%20jobs)
Answer:
A
Step-by-step explanation:
● first one:
The diagonals of a rhombus are perpendicular to each others wich means that they form four right angles.
STP is one of them so this statement is true.
● second one:
If ST and PT were equal this would be a square not a rhombus.
● third one:
If SPQ was a right angle, this woukd be a square.
● fourth one:
Again if the diagonals SQ and PR were equal, this would be a square.
Answer:
ABD = CDB
AB is parallel to DC
Step-by-step explanation:
angle a and c are right angles so they are equal and angle b and d are equal because they have a line that touch both letters
AB and DC are parellel because they are the same looking lines just on oppisite sides
