The correct answer is B) y = 120000x + 420000.

We multiply 120,000 by x since that is the cost per person per day, and x is the number of days.  We add 420,000 because that is the one time cost of the round trip airfare.

klio [65]

Answer:

P(X<3) = 0.01004

Step-by-step explanation:

From the given information:

Consider the application of Poisson distribution P(X = x ) = \dfrac{e^{-\lambda} \lambda ^x}{x!} with the parameter \lambda = 8.4;

Therefore, we can calculate the required probability as follows:

P(X< 3) = P(X = 0) + P(X = 1) + P(X =2)

P(X< 3) = \dfrac{e^{-8.4} 8.4^0}{0!} +  \dfrac{e^{-8.4} 8.4^1}{1!} +  \dfrac{e^{-8.4} 8.4^2}{2!}

P(X< 3) =e^{-8.4}( 1 + 8.4+35.28)

P(X<3) = 0.01004

What is the answer?
Vinvika [58]

Answer:

1:200

5.6 cm^2 : y (as actual area)

y = 200 mutifly 5.6 cm^2

y= 1120 cm^2

We know 1m =100cm

so, 1m^2 =100cm x 100 cm = 1000cm^2

y= 1120 m^2/ 100x100

 = 0.112 m^2
