Answer:

3 / 4

Step-by-step explanation:

We can realize that both the numerator and denominator have a common factor of 9. We can divide them both by 9 to get:

3 / 4

This fraction is in simplest form.

I’m really struggling with these proofs. We just started learning them and I’m highly confused!! Please help :)

I'm not sure about what exactly your teacher is looking for, but the actual congruency conjecture you would use is:

(angle symbol) 1 (congruency symbol) (angle symbol) 8 - Because they are alternate exterior angles

The exponential distribution can be used to solve Poisson-type problems in which the intervals are not time. The Air Travel Cons

frutty [35]

Answer:

a) $P(X \ge 490) = 0.628$

b) $P(X \leq 190) = 0.165$

Step-by-step explanation:

a) This is an exponential distribution question since it is a poisson type problem

Mean rate is 0.95 per 1000 passengers

Mean rate, $\lambda = 0.95/1000$

$\lambda = 0.00095$ per passenger

Probability that at least 490 passengers will have their baggage handled properly before the next mishandling occurs :

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

$P(X \ge 490) = e^{-490 * 0.00095}$

$P(X \ge 490) = e^{-0.4655}\\P(X \ge 490) = 0.628$

b) Probability that the number will be fewer than 200 passengers

$P(X \leq 190) = 1 - P(X \geq 190)\\P(X \leq 190) = 1 - e^{-190 \lambda} \\P(X \leq 190) = 1 - e^{-190 *0.00095}$

$P(X \leq 190) = 1 - 0.835\\P(X \leq 190) = 0.165$
