Answer:
1 hour 20 minutes
Step-by-step explanation:
Time to fix car ( repair time ) = 20 minutes
Breakdown rate ( λ ) = 2 car per hour
<u>first step : determine service the service rate ( μ )</u>
= 60 minutes / 20 minutes
= 3 cars per hour
<u>next : determine the average waiting time for a disabled car </u>
= 1 / (μ - λ)
= 1 / service rate - breakdown rate
= 1 / ( 3 - 2 )
= 1 / 1 = 1 hour
Finally Total time for a disabled car to be fixed
= repair time + average waiting time
= 20 minutes + 60 minutes
= 1 hour 20 minutes
Answer:7,500
Step-by-step explanation:
no way she gonna make 70 k in a year with that percentage
In the diagram, ∠2 and ∠6 are the same as well as ∠4 and ∠8. If we added ∠2 and ∠6, they would equal 180°...therefore, if we subtract 106 from 180, we are left with 74° for the answer to ∠8
