Determine f(5) <br> f(x)=2x'2-1 if x &lt; or equal to -1<br> 3x+2 if x &gt; -1
kolezko [41]

Answer:

To make it clearer, I just put every thing under the formal form

f(x) = \left \{ {{2x^2-1~~~~if~~~~  x\leq -1} \atop {3x+2~~~~~if~~~~~x>-1}} \right.

Step-by-step explanation:

Now, you have 2 equations with 2 conditions. One is > -1, and one is < -1.

The question is about f (5). So, which equation you use to replace x = 5? The first one or the second one? and why?

Answering those questions help you understand how it works.

Jobs arrive at the server at the rate of 8 jobs per hour. The service takes 3 minutes, on the average. This system is modeled by
Gemiola [76]

Answer:

2249 / 540000

Step-by-step explanation:

Jobs arrival time = 8 jobs per hour

Service takes 3 minutes on average

Frame size = 5 second

capacity of each frame = 3 jobs

<u>Determine the transition probability matrix for number of jobs in system </u>

First step : find probability of job arrival

= 8 / ( 5 * 3600)

=  8 / 18000 =  1 / 2250

next : determine probability of service

= ( 3 * 5 )/ 3600

= 15 / 3600 = 1/240

Finally the transition probability matrix ( p10 )= { 1, 0}

=  probability of service(1 - probability of arrival)

 = 1/ 240 * ( 1 - 1 / 2250 )

= 1 / 240 * ( 2249 / 2250 )

= 2249 / 540000
