The answer is 76/98 because 22+76 is 98
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:
x = {-0.44, 1.69}
Step-by-step explanation:
Multiply by the denominator to eliminate the fraction.
3 = x(4x -5)
4x^2 -5x -3 = 0 . . . . . subtract 3 and put in standard form
Using the quadratic formula with a=4, b=-5, c=-3, we have the solutions as ...
![x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}=\dfrac{-(-5)\pm\sqrt{(-5)^2-4(4)(-3)}}{2(4)}\\\\x=\dfrac{5\pm\sqrt{73}}{8}\approx \{-0.443, 1.693\}](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B-b%5Cpm%5Csqrt%7Bb%5E2-4ac%7D%7D%7B2a%7D%3D%5Cdfrac%7B-%28-5%29%5Cpm%5Csqrt%7B%28-5%29%5E2-4%284%29%28-3%29%7D%7D%7B2%284%29%7D%5C%5C%5C%5Cx%3D%5Cdfrac%7B5%5Cpm%5Csqrt%7B73%7D%7D%7B8%7D%5Capprox%20%5C%7B-0.443%2C%201.693%5C%7D)
Solutions rounded to hundredths are ...
x = -0.44
x = 1.69
_____
A graphing calculator can show the x-intercepts easily, so it works well to write the equation in the form
f(x) = 0
3/(4x -5) -x = 0
Answer:
Options (3) and (6)
Step-by-step explanation:
"A straight line is a set of all points between two points and extending beyond these points."
Therefore, from the given diagram,
Arrows connecting set of two points B and C and D and E will be straight lines.
Geometrically we denote them with an arrow over the line.
and ![\overleftrightarrow {DE}](https://tex.z-dn.net/?f=%5Coverleftrightarrow%20%7BDE%7D)
Therefore, Options (3) and (6) will be the answer.
