Cars cross a certain point on the highway in accordance with a Poisson process with rate = 3 per minute. If Al runs across the h

Svetradugi [14.3K]

Answer:

The probability is 0.2212

Solution:

As per the question:

Poisson rate, $\lambda = 3/min = \frac{3}{60}\ s = 0.05\ s$

Now,

Let

X: time of waiting for the next vehicle on the highway

Now,

To find the probability of the next vehicle to arrive after 10 s

The probability distribution function is given by:

$f(x) = \lambda e^{- \lambda x}$

Now,

P(X < x) = $1 - e^{- \lambda x}$

$P(X \leq x) = 1 - e^{- 0.05 x}$

For X> 0,

P(X > x) = $e^{- \lambda x}$

P(X < 5) = $1 - e^{- 5\lambda} = 1 - e^{- 0.25} = 1 - 0.7788 = 0.2212$

Carole is very tired and makes coffee. why would newton say that she must use her hand to put up the cup

Marat540 [252]

<span>newton say that she must use her hand to put up the cup because the work is equal to force times it distance, that is in the same direction of the force applied. if carole used her hand to put up the cup, then he is not applying any work because the displacement is not in the same direction of the force</span>
