masha68 [24]

the cost of airfare on Friday is $141

<u>Step-by-step explanation:</u>

Here we have , The average cost of airfare for a one-way ticket from Las Vegas to Los Angeles was $67 for the days of Monday through Friday. The cost of airfare Monday through Thursday was $40, $44, $50, $60 respectively. We need to find What was the cost of airfare on Friday.Let's find out:

Let amount of Friday be x , So Average cost of airfare for a one-way ticket from Las Vegas to Los Angeles  is given by :

⇒ \frac{40+44+50+60+x}{5} =67

⇒ \frac{194+x}{5} =67

⇒ 194+x =67(5)

⇒ x =335-194

⇒ x =141

Therefore , the cost of airfare on Friday is $141

A new​ phone-answering system installed by a certain utility company is capable of handling ten calls every 10 minutes. Prior to
Mrrafil [7]

Answer:

0.0137

Step-by-step explanation:

Let X be the random variable that measures the number of incoming calls every ten minutes.

If the incoming calls to the system are Poisson distributed with a mean equal to 5 every 10 minutes, then the probability that there are k incoming calls in 10 minutes is

\bf P(X=k)=\frac{e^{-5}5^k}{k!}

If the phone-answering system is capable of handling ten calls every 10 minutes, we want to find

P(X>10), or the equivalent 1 - P(X≤ 10).  

But

1 - P(X≤ 10)= 1 -(P(X=0)+P(X=1)+...+P(X=10)) =

\bf 1-\left (\frac{e^{-5}5^0}{0!}+\frac{e^{-5}5^1}{1!}+...+\frac{e^{-5}5^{10}}{10!}\right)=\\=1-e^{-5}\left(\frac{5^0}{0!}+\frac{5^1}{1!}+...+\frac{5^{10}}{10!}\right)=1-0.9863=0.0137

So, the probability that in a 10-minute period more calls will arrive than the system can​ handle is 0.0137
