Answer:
imaginary roots
Step-by-step explanation:
For a quadratic in the form ...

the discriminant is ...

You have a=1, b=-6, c=12, so the discriminant is ...
d = (-6)² -4(1)(12) = 36 -48 = -12
When the discriminant is negative, both roots are complex. When the discriminant is not a perfect square, both roots are irrational. Here, the discriminant is negative and not a perfect square, so the roots are complex with an irrational imaginary part.
The best single descriptor is <em>imaginary root</em>.
_____
The roots are (-b±√d)/(2a) = (6 ± 2i√3)/2 = 3 ± i√3. These roots have a rational real part and an irrational imaginary part. When the number with an imaginary part has a non-zero real part, it is called "complex", rather than "imaginary."
This is an example of a factor pattern called the Difference of Two Squares.

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
