Answer:
1. 0.55
2. 4.95
Step-by-step explanation:
450x20/1000/1000x8
= 9 megabytes/sec
the service time u = 10 megabytes per sec
ρ = 9÷10 = 0.9
1. the mean residence tr of a packet in the system
= 2-ρ/2 x u(1-ρ)
= 2-0.9/2 x 10(1-0.9)
= 0.55x1
= 0.55
2. the mean number of packets that are waiting to be processed inthe queue
= (2-p) x p/2 x (1-p)
= 2-0.9 x 0.9/2 x 1-0.9
= 1.1 *0.45 x 0.1
= 4.95
Answer:
c
Step-by-step explanation:
using the 10 = 7x - 20 for simplicity.
10 = 7x - 20 add 20 to both sides
30 = 7x divide both sides by 7
30/7 = x
Answer:
$211.12
Step-by-step explanation:
Answer:
The graph in the attached figure
Step-by-step explanation:
we have
isolate the variable y
Adds 10 both sides
Divide by 2 both sides
The solution of the inequality is the shaded area below the dashed line
The slope of the dashed line is positive
The y-intercept of the dashed line is (0,5) (value of y when the value of x is equal to zero)
The x-intercept of the dashed line is (-3.33,0) (value of x when the value of y is equal to zero)
