Ashley has a box of donuts to distribute among her colleagues. There are eight chocolate donuts, twelve glazed donuts, ten jelly

donuts, two cinnamon donuts, and four rainbow sprinkled donuts in the box. Ashley predicts that when she draws a donut out of the box without looking, she will draw a glazed donut one-third of the time.
Which activity would best allow Ashley to test her prediction?

A.
Randomly select a donut from the box and see if it is a glazed donut.
B.
Randomly select a donut. Then, continue to draw another donut until twelve glazed donuts are drawn.
C.
Randomly select and replace a donut 72 times. Then, observe how close to 18 times a glazed donut is drawn.
D.
Randomly select and replace a donut 72 times. Then, observe how close to 24 times a glazed donut is drawn.

There are 200 seats on the Boeing 747 flight from Dallas to Houston. Assume that the number of passengers who buy tickets but do
Dimas [21]

Answer:

a. The number of reservations should the manager accept is 225 bookings

b. The probability that the manager will have to compensate for customers when there are not enough seats is 0.2317

Step-by-step explanation:

According to the given data we have the following:

Cost of Overage Co = 800

Cost of Underage Cu = 475

Hence, Critical Ratio = Cu/(Cu+Co)

Critical Ratio = 475/1275

Critical Ratio = 0.3725

To calculate the number of reservations should the manager accept we would have to calculate first the Optimal Number of Overbooking as follows:

Z = NORM.S.INV(0.3725) = -0.3251

Optimal Number of Overbooking = Mean of No show + Z*Sd of No show

Optimal Number of Overbooking = 30 - 0.3251*15

Optimal Number of Overbooking = 25.12

Optimal Number of Overbooking = 25

a. Therefore, Number of reservation = Capacity + Overbooking = 200+25 = 225 bookings

b. Number of Overbooking = 220 - 200 = 20

Manager will have to compensate if there will be less than or equal to 19 No show.

Therefore, to calculate the probability that the manager will have to compensate for customers when there are not enough seats we have to calculate the following formula:

P(Compensation) = P(No Show <= 19) = P(Z <= (19-30/15))

P(Compensation) = P(Z<= - 0.7333)

P(Z< - 0.7333) = NORM.S.DIST(-0.7333,1)

P(Z< - 0.7333) = 0.2317

P(compensation) = 0.2317

Probability of Compensation = 0.2317

3. The width of a rectangle is 4 feet less than the length. The area is
mina [271]

Answer:

L = 6, w = 2

Step-by-step explanation:

Let w = width of rectangle

Let L = length of rectangle

w = L - 4

Area of rectangle = Lw

L (L - 4) = 12

L^2 - 4L = 12

L^2 - 4L - 12 = 0

(L - 6)(L + 2) = 0

L - 6 = 0

L = 6 (the other option doesn't work because dimensions can't be negative)

w = L - 4

w = 6 - 4

w = 2

Double check

A = Lw

A = 6 x 2

A = 12

It matches so we are right.

There are 12 balls in a bag. One is blue and one is red. What is the exact probability that the blue ball is drawn first and the
Fiesta28 [93]
<h3>The exact probability that the blue ball is drawn first and the red ball is drawn second is \frac{1}{132}</h3>

<em><u>Solution:</u></em>

<em><u>The probability of an event is given as:</u></em>

Probability = \frac{ \text{ number of favorable outcomes }}{ \text{ total number of possible outcomes }}

Given that,

There are 12 balls in a bag

One is blue and one is red

Favorable outcome = blue ball is drawn first

Favorable outcome = 1

Therefore,

Probability = \frac{1}{12}

Now, without replacement, red ball is drawn second

Therefore,

Total possible outcomes = 12 - 1 = 11

Probability = \frac{1}{11}

<em><u>What is the exact probability that the blue ball is drawn first and the red ball is drawn second?</u></em>

Total\ probability = \frac{1}{12} \times \frac{1}{11} = \frac{1}{132}

Thus the exact probability that the blue ball is drawn first and the red ball is drawn second is \frac{1}{132}
