"students arrive randomly at the desk of the computer lab. there is only one service agent, and the time required for inquiry varies from student to student. arrival rates have been found to follow the poisson distribution, and the service times follow the negative exponential distribution. the average arrival rate is 12 students per hour, and the average service rate is 20 students per hour. on average, how long does it take to service each student?

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or

nothing extraneous has been found!

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.
