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:
3 years
Step-by-step explanation:
In this problem, the initial number of students at time t = 0 is
We know that the number of students increases by 5 % every year. This means that we can write the student's population as
where
t is the time, measured in years
Here we want to find after how many years t the student's population will exceed the maximum capacity of the school, which is
N = 1100
To solve the problem, we just put n = 1100 and we solve for t. We find:
Which means that the student's population reaches the maximum capacity of the school after 2.37 years. Since we want this number to be an integer, this means that the enrollment will exceed the capacity in 3 years.
answer:
(5,5).
explanation:
ordered-pair: (8,8) (2,2)
x1 (8), y1 (8). x2 (2), y2 (2)
x: (8+2/2)= 5.
y: (8+2/2)= 5.

Answer:
The area of Nancy's garden is
Step-by-step explanation:
I assume that the Nancy's garden is a rectangle shape
To find the area first convert mixed number to an improper fraction
Therefore
The area is equal to
