At the center of espionage in Kznatropsk one is thinking of a new method for sending Morse telegrams. Instead of using the tradi
alexgriva [62]

Answer:

It takes less time sending 5 letters the traditional way with a probability of 36.7%.

Step-by-step explanation:

First we must take into account that:

- The traditional method is distributed X ~ Poisson(L = 1)

- The new method is distributed X ~ Poisson(L = 5)

P(X=x)=\frac{L^{x}e^{-L}}{x!}

Where L is the intensity in which the events happen in a time unit and x is the number of events.

To solve the problem we must calculate the probability of events  (to send 5 letters) in a unit of time for both methods, so:

- For the traditional method:

P(X=5)=\frac{1^{5}e^{-1}}{1!}\\\\P(X=5) = 0.367

- For the new method:

P(X=5)=\frac{5^{5}e^{-5}}{5!}\\\\P(X=5) = 0.175

According to this calculations we have a higher probability of sending 5 letters with the traditional method in a unit of time, that is 36.7%. Whereas sending 5 letters with the new method is less probable in a unit of time. In other words, we have more events per unit of time with the traditional method.

Cerrena [4.2K]

Answer:

First Answer:

$15,060.

Second Answer:

9.96 miles.

Third Answer:

$3.27.

Step-by-step explanation:

First Question:

Cost of the rented car = 50 + 0.20 = $50.20

How much did Matt's family spend for the car:

1 mile = $50.20

300 miles = ?

300 × 50.20

= $15,060.

Second Question:

If Hayden spent $500 for her rented car, how many miles did she drive:

$50.20 = 1 mile

$500 = ?

500 ÷ 50.20 = 9.96 miles.

Third Question:

What is the cost per gallon of gas:

24 gallons = $78.48

1 gallon = ?

78.48 ÷ 24 = $3.27.

Solve the equation by completing the square. 2x-18x+58=0
lubasha [3.4K]
x^{2}  -18x+58=0

We have got quadratic equation. We calculate it by using Δ.

\Delta=(-18)^{2} -4*1*58=324-232=92>0
\sqrt{\Delta} = \sqrt{92} =2 \sqrt{23}

x_1= \frac{-b- \sqrt{\Delta} }{2a} = \frac{18-2 \sqrt{23} }{2} =9- \sqrt{23}
∨
x_2= \frac{-b+ \sqrt{\Delta} }{2a} = \frac{18+2 \sqrt{23} }{2} =9+ \sqrt{23}

Hope it helps :)
