The problem of matching aircraft to passenger demand on each flight leg is called the flight assignment problem in the airline i
Darina [25.2K]

Answer:

Step-by-step explanation:

Given that the demand for the 6 p.m. flight from Toledo Express Airport to Chicago's O'Hare Airport on Cheapfare Airlines is normally distributed with a mean of 132 passengers and a standard deviation of 42

Let X be the no of passengers who report

X is N(132, 42)

Or Z is \frac{x-132}{42}

a) Suppose a Boeing 757 with a capacity of 183 passengers is assigned to this flight.

the probability that the demand will exceed the capacity of this airplane

=P(X>183) = P(Z>1.21) =

=0.5-0.3869\\=0.1131

b)  the probability that the demand for this flight will be at least 80 passengers but no more than 200 passengers

=P(80\leq x\leq 200)\\= P(-1.23\leq z\leq 1.62)\\

=0.4474+0.3907

=0.8381

c) the probability that the demand for this flight will be less than 100 passengers

=P(x

d) If Cheapfare Airlines wants to limit the probability that this flight is overbooked to 3%, how much capacity should the airplane that is used for this flight have? passengers

=P(Z>c)=0.03\\c=1.88\\X=132+1.88(42)\\=210.96

e) 79th percentile of this distribution

=132+0.81(42)\\= 166.02

Solve. −35x+15>720 Drag and drop a number or symbol into each box to show the solution.
vampirchik [111]

Answer:

The solution of the inequality - 35x + 15 > 720  is x

Step-by-step explanation:

Consider the given inequality

- 35x + 15 > 720

Subtract both side by 15 , we get

- 35x + 15 - 15 > 720 - 15

- 35x > 705

Multiply both sides by -1 (Reverse the inequality )

(-35x)(-1) < 705 (-1)

35x < -705

Now, divide both side by 35

\frac{35x}{35}=\frac{-705}{35}

\Rightarrow x=\frac{-141}{7}

Thus, the solution of the inequality - 35x + 15 > 720  is x
