Assume a Poisson random variable has a mean of 5 successes over a 125-minute period.

goldenfox [79]

Answer:

$\mu = 25$

$\lambda =0.04$

$P(X > 65 ) =0.0742$

Step-by-step explanation:

From the question we are told that

The number of success is n = 5

The time duration is N = 125 minutes

Generally the mean of the random variable is mathematically represented as

$\mu = \frac{N}{n}$

=> $\mu = \frac{125}{5}$

=> $\mu = 25$

Generally the rate parameter is mathematically represented as

$\lambda = \frac{1}{\mu}$

=> $\lambda = \frac{1}{25}$

=> $\lambda =0.04$

Generally the cumulative distribution function for exponential distribution function is

$F(x) = \left \{0 \ \ \ \ \ \ x \le 0}} \atop {1 -e^{-\lambda t }\ x>0}} \right.$

Generally the probability that the time to success will be more than 63 minutes is mathematically represented as

$P(X > 65 ) = 1 - P(X \le 65)$

Here

$P(X \le 65) = 1 -e^{-65 * \lambda }$

=> $P(X \le 65) = 1 -e^{-65 * 0.04 }$

=> $P(X \le 65) = 0.92573$

$P(X > 65 ) = 1 - 0.92573$

$P(X > 65 ) =0.0742$

If the foreign exchange rate between the U.S. dollar and the Danish krone is 1:2.50, how many Danish kroner will you get for $5?

enyata [817]

$\bf \begin{array}{ccll} US~\$&Danish~\$\\ \cline{1-2} 1&2.50\\ 5&d \end{array}\implies \cfrac{1}{5}=\cfrac{2.50}{d}\implies d=\cfrac{5\cdot 2.50}{1}\implies d=12.5$

A horizontal force of 480 n is applied to a stationary wooden box in one direction and a 600 n horizontal force is applied in th

maksim [4K]

Answer:

Step-by-step explanation:

In a static position, the sum of the forces is always 0.

so:

F1 = 480 N

F2 = -600 N

F3 = ?

F1 + F2 + F3 = 0

480 - 600 + F3 = 0

F3 = 120 N (the answer is positive, so the force acts in the same direction as F1)
