Suppose users share a 2 mbps link. also suppose each user transmits continuously at 1 mbps when transmitting, but each user transmits only 20 percent of the time. (consider statistical multiplexing discussed in lecture.) (a) (3 points) when circuit switching is used, how many users can be supported? (b) (3 points) for the reminder of this problem, suppose packet switching is used. why will there be essentially no queuing delay before the link if two or fewer users transmit at the same time? why will there be a queuing delay if three users transmit at the same time? (c) (3 points) find the probability that a given user is transmitting. (d) (6 points) suppose now there are three users. find the probability that at any given time, all three users are transmitting simultaneously.

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500

the graph in the attached figure

step-by-step explanation:

we have

using a graphing tool

the graph in the attached figure

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
