The cost (c) to hire a dog trainer is varies directly with the amount of time (h) in hours spent training the dog.
NNADVOKAT [17]

Answer:

Part A) The proportional equation is c=55h

Part B) 8 hours of training

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

Let

c -----> the cost to hire a dog

h ----> the amount of time in hours

The linear equation is equal to

c=kh

Sue spent $660 on 12 hours of obedience training for her dog Muffin

Find the value of k (constant of proportionality)

k=y/x

substitute the values

k=660/12=55

therefore

The linear equation is

c=55h

For c=\$440

Find the value of h

substitute in the equation and solve for h

440=55h

h=440/55=8\ hours

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
