Answer:
only A is correct
Step-by-step explanation:
To get the equation of the given line, we just have to see if the point given fits into any of the equation
The given point is (15,3)
a) y = 1/5x = 1/5 * 15 = 3
This is correct
b) y = -5(-75) = -375; this is not correct
c) y = 3x
y = 3(15) = 45
This is not correct
d) y = 15x
y = 15(15) = 225
This is incorrect
e) y = -1/5x
y = -1/5 * 15 = -3
This is incorrect
f) y = 5x
y = 5(15) = 75
This is also incorrect
Answer:
3 games
Step-by-step explanation:
The computation of the maximum number of games that he could buy is shown below:
= Amount available - already spent
= $75 - $28
= $47
If each game cost $15
So, the maximum no of games is
= $47 ÷ $15
= 3.133
= 3 games
Answer:
0.578 hours
Step-by-step explanation:
If boxes of books arrive at a rate of 1 per 8 minutes, the number of boxes per hour is:
![\mu =\frac{1}{8}*60=7.5/hour](https://tex.z-dn.net/?f=%5Cmu%20%3D%5Cfrac%7B1%7D%7B8%7D%2A60%3D7.5%2Fhour)
If the service rate is 1 box per 6.5 minutes, the number of boxes per hour is:
![\mu =\frac{1}{6.5}*60=9.231/hour](https://tex.z-dn.net/?f=%5Cmu%20%3D%5Cfrac%7B1%7D%7B6.5%7D%2A60%3D9.231%2Fhour)
The average time from when a box of novels arrives until shredding is complete is:
![t=\frac{1}{\mu-\lambda}=\frac{1}{9.231-7.5} \\t=0.578\ hours](https://tex.z-dn.net/?f=t%3D%5Cfrac%7B1%7D%7B%5Cmu-%5Clambda%7D%3D%5Cfrac%7B1%7D%7B9.231-7.5%7D%20%5C%5Ct%3D0.578%5C%20hours)
The average time in the system is 0.578 hours.
