Answer:

The value is  P(X = 3) = 0.1804  

Step-by-step explanation:

From the question we are told that

   The number of customer that enter the tellers every 5 minutes is  \lambda   = 2

Generally the  probability that exactly three customers enter the queue in a randomly selected five-minute period is mathematically represented as

      P(X = 3) = \frac{e^{- \lambda} * \lambda^{3}}{3!}

=>   P(X = 3) = \frac{e^{- 2} * \lambda^{3}}{3!}

=>   P(X = 3) = 0.1804

Answer:

(4, 0)

Step-by-step explanation:

given the 2 equations

y = x - 4 → (1)

- 4x - 6y = - 16 → (2)

substitute y = x - 4 into (2)

- 4x - 6(x - 4) = - 16

- 4x - 6x + 24 = - 16

- 10x + 24 = - 16 ( subtract 24 from both sides )

- 10x = - 40 ( divide both sides by - 10 )

x = 4

substitute x = 4 into (1) for corresponding value of y

y = 4 - 4 = 0

solution is (4, 0)

8·11= 88

11-5= 6
