Answer:
2w+2(2w-7)
Step-by-step explanation:
the first 2w is the length of the two widths, and the (2w-7) is the length of the length, and we multiply by two because there are two sides.
Hello!
To find the area of a rectangle you do length * width
You can plug in the values you know
(x - 2) * 5 = 30
Divide both sides by 5
x - 2 = 6
Add 2 to both sides
x = 8
The answer is 8

Answer:
Explanation has been given below
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
