A travelling salesman sells milkshake mixing machines and on average sells 8.4 machines per month. He needs to sell at least 3 m
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

Solve for . 5w-26=-4(w-7) Simplify your answer as much as possible. PLZ HELP
NikAS [45]

Answer:

w = 6

Step-by-step explanation:

5w-26 = - 4 (w - 7)   multiply -4 through

5w - 26 = - 4w + 28  add 4w to each side to cancel it out on the right

5w + 4w - 26 = 28  

9w - 26 = 28  Now add 26 to each side

9w - 26 + 26 = 28 + 26

9w = 54   Now divide each side by 9

(9w)/9 = 54/9

w = 6
