Answer:

<u>2x⁵ + x⁴ - x³ + 6x² + 3x - 3</u>

Step-by-step explanation:

Given :

  • f(x) = x³ + 3
  • g(x) = 2x² + x - 1

Finding (f × g)(x) :

  • f(x) × g(x)
  • (x³ + 3)(2x² + x - 1)
  • 2x⁵ + 6x² + x⁴ + 3x - x³ - 3
  • <u>2x⁵ + x⁴ - x³ + 6x² + 3x - 3</u>

Suppose that the length of a phone call in minutes is an exponential random variable with parameter λ = 1/ 8. If someone arrives
Elis [28]

Answer:

a) P=0.535

b) P=0.204

c) P=0.286

Step-by-step explanation:

The exponential distribution is expressed as

F(x>t)=e^{-\lambda t}

In this example, λ=1/8=0.125 min⁻¹.

a) The probability of having to wait more than 5 minutes

F(x>5)=e^{-0.125*5}=e^{-0.625}=0.535

b) The probability of having to wait between 10 and 20 minutes

F(1020)=e^{-0.125*10}-e^{-0.125*20}\\\\F(10

c) The exponential distribution is memory-less, so it is independent of past events.

If you have waited 5 minutes, the probability of waiting more than 15 minutes in total is the same as the probability of waiting 15-5=10 minutes.

F(x>15|t^*=5)=F(x>15)/F(x>5)=\frac{e^{-0.125*15}}{e^{-0.125*5}}=e^{-0.125*(15-5)}\\\\ F(x>15|t^*=5)=e^{-0.125*(10)}=F(x>10)=0.286
