Answer:
x = 4 , y = ⅕
Step-by-step explanation:
2x + 5y = 9 (1)
3x - 5y = 11 (2)
Add (1) and (2)
5x = 20
x = 4
Using (1), find y
2(4) + 5y = 9
5y = 1
y = ⅕

Step-by-step explanation:
a) inter arrival times are exponentially distributed with mean 1/n , where n = rate = 1/sec.
probability distribution function is F(t)=n*exp(-n*t).
reference to any kth packet and the (k-1)th packet
the answer is = integration of F(t).dt with limits 0 to 2 = 1 - exp(-2*n) = 1 - exp(-2)
b) t=5 , P(q) = exp(-5)*(5)^q/factorial(q)
probability of fourth call within t=5 seconds is =
that is P(4) P(5) ...... = 1 - ( P(0) P(1) P(2) P(3) ) ; put the values and get the answer.
c) number of calls/rate = 4/n = 4 seconds
