Answer:

A. 0.9510

B. 0.0480

C. 0.0490

D. No, I would not feel comfortable accepting the shipment if one item was found defective, because the probability is quite small to obtain 1 or more defective items.

Answer:

x = 200

Step-by-step explanation:

Multiply by 4:

x + 120 + 2x = 720

3x = 600 . . . . . . collect terms, subtract 120

x = 200 . . . . . . . divide by 3

_____

<em>Check</em>

(200/4 +30) +(200/2) = 180

(50 +30) + 100 = 180

80 + 100 = 180 . . . . . true

_____ _____

<em>Alternate solution</em>

If you like, you can simply work with the equation given.

(3/4)x + 30 = 180 . . . . collect terms

(3/4)x = 150 . . . . . . . . . subtract 30

x = 200 . . . . . . . . . . . . multiply by 4/3

I know it seems that alot of people like on here so people do their work but I really need help!!! I have a set of problems that

marshall27 [118]

Answer:

No Problem, I know That I personally can't stand it when people just give me the number. So another way to think of this problem is "How many 2/3 are in 3 cups." So try drawing 3 rectangles to represent 3 cups and then draw two lines inside those rectangles so that there are 3 rectangles inside each one and then shade in two of the smaller rectangles in a way that you can tell them all apart preferably different colors and then just count them.

Step-by-step explanation:

Hope this is enough to help you understand it, if not then feel free to ask for more info in the comments. :)

Changes in airport procedures require considerable planning. Arrival rates of aircrft are important factors that muct be taken i

Irina18 [472]

Answer:

a) 0.1558

b) 0.7983

c) 0.1478

Step-by-step explanation:

If we suppose that small aircraft arrive at the airport according to a <em>Poisson process</em> <em>at the rate of 5.5 per hour</em> and if X is the random variable that measures the number of arrivals in one hour, then the probability of k arrivals in one hour is given by:

$\bf P(X=k)=\displaystyle\frac{(5.5)^ke^{-5.5}}{k!}$

(a) What is the probability that exactly 4 small aircraft arrive during a 1-hour period?

$\bf P(X=4)=\displaystyle\frac{(5.5)^4e^{-5.5}}{4!}=0.1558$

(b) What is the probability that at least 4 arrive during a 1-hour period?

$\bf P(X\geq4)=1-P(X$

(c) If we define a working day as 12 hours, what is the probability that at least 75 small aircraft arrive during a working day?

If we redefine the time interval as 12 hours instead of one hour, then the rate changes from 5.5 per hour to 12*5.5 = 66 per working day, and the pdf is now

$\bf P(X=k)=\displaystyle\frac{(66)^ke^{-66}}{k!}$

and we want <em>P(X ≥ 75) = 1-P(X<75)</em>. But

$\bf P(X$

hence

P(X ≥ 75) = 1-0.852 = 0.1478
