Andrew [12]

Answer:

Yuri made 947 more copies than Nathan.

Step-by-step explanation:

Since we are finding the difference from the amount Yuri and Nathan made, the operation is subtraction. Since Yuri made more copies, his number will go first: 1272-325. Then, we solve by subtracting the two numbers, and you should get 947.

Thus, Yuri made 947 more copies than Nathan.

A queue with a single server receives 50 requests per second on average. The average time for the server to address a request is
sdas [7]

Answer:

P(X=k) = \displaystyle\frac{(2.5)^ke^{-2.5}}{k!}

Step-by-step explanation:

This is a typical example where the Poisson distribution is a good choice to model the situation.

In this case we have an interval of time of 50 milliseconds as average time for the server to address one request and 50 requests per second.  

By cross-multiplying we determine the expected value of requests every 50 milliseconds.  

We know 1 second = 1,000 milliseconds

50 requests __________ 1000 milliseconds

 x requests __________ 50 milliseconds

50/x = 1000/50 ===> x = 2.5  

and the expected value is 2.5 requests per interval of 50 milliseconds.

According to the Poisson distribution, the probability of k events in 50 milliseconds equals

\bf P(X=k) = \displaystyle\frac{(2.5)^ke^{-2.5}}{k!}

Find two numbers a and b whose sum a + b is 4 and whose difference a − b is 8 .
PtichkaEL [24]

Answer:

see below

Step-by-step explanation:

 a + b = 4

 a -  b = 8        add the two equations to solve the system of equations

a + a + b + (- b) = 4 + 8

 2a  + 0b = 12

      2a/2  = 12 /2

           a  =  6

    a + b = 4

    a - a + b = 4 -a

            b = 4 - 6

            b =  -2
