Answer: The answer is the second equation (y = 3x-4 and y = -1/3x - 2)

Step-by-step explanation:

This is because two lines are perpendicular when the slopes of the equations are negative reciprocals from each other.

1.a sphere with a radius of three units

By definition, the volume of a sphere is:
$V = ( \frac{4}{3} ) (\pi) (r ^ 3)
$
Substituting values we have:
$V=(\frac{4}{3})(\pi)(3^3)$
Rewriting we have:
$V = (4) (\pi) (3 ^ 2)

V = (4) (\pi) (9)

V = 36\pi$

2.a cone with a diameter of twelve units and a height of three units

By definition, the volume of a cone is given by:
$V = \frac{1}{3} (\pi) (r ^ 2) (h)
$
Substituting values we have:
$V = \frac{1}{3} (\pi) ((\frac{12}{2}) ^ 2) (3)
$
Rewriting we have:
$V = (\pi) (6 ^ 2)

V = 36\pi$

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
