Answer:
<h2>The graph of the equation is the set of all points that are solutions to the equation.</h2>Step-by-step explanation:
The given equation is
The true statement is the first one, because the graph of an equation always represent all points that are solutions. That is, all solutions for this equation are all the points placed on the line. The graph of the given linear equation is attached.
You can see in the graph that the points (-6,7) and (-4,-6) are not solutions for this equation, because they aren't on the line.
Also, you can see that the equation represents an infinite line, that is, the equation doesn't have a single solution.
Therefore, the true statement is the first one.

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 =
=
