Hi,

Solving:

\frac{2 {y}^{2} - 6y - 20}{4y + 12} \div \frac{ {y}^{2} + 5y + 6}{ 3 {y}^{2} + 18y + 27 } \\ \frac{2 {y}^{2} - 6y - 20}{4y + 12} \div \frac{3 {y}^{2} + 18y + 27 }{{y}^{2} + 5y + 6} \\ \frac{2( {y}^{2} - 3y - 10)}{4y + 12} \div \frac{3 {y}^{2} + 18y + 27}{ {y}^{2} + 5y + 6} \\ \frac{2( {y}^{2} - 3y - 10}{2(2y + 6)} \times \frac{3 {y}^{2} + 18y + 27}{ {y}^{2} + 5y + 6} \\ \frac{ \not2( {y}^{2} - 3y - 10) }{ \not2(2y + 6)} \times \frac{3( {y}^{2} + 6y + 9) }{ {y}^{2} + 5y + 6} \\ \frac{ {y}^{2} + 2y - 5y - 10 }{2(y + 3)} \times \frac{3( {y}^{2} + 6y + 9) }{ {y}^{2} + 3y + 2y + 6} \\ \frac{y \times (y + 2) - 5(y + 2)}{2(y + 3)} \times \frac{3(y + 3)^{2} }{y \times (y + 3) + 2(y + 3)} \\ \frac{ (y + 2) \times (y - 5)}{2(y + 3)} \times \frac{3(y + 3)^{2} }{(y + 3) \times (y + 2)} \\ \frac{y - 5}{2(y + 3)} \times 3(y + 3) \\ \frac{y - 5}{2} \times 3 = \frac{3y - 15}{2} \: \: \: \: \: \: \: \: \: \: \: \: result

What isa the area of the square whoose sides mesure 3x + 4​
olga nikolaevna [1]

Answer:

9^{2} + 24x + 16

Step-by-step explanation:

If it is a square, all sides are equal. An area of a square would be side x side. You would multiply 3x + 4 and 3x + 4 together. I used the foil method (multiply first, then outside, inside, last) or (3x * 3x, 3x * 4, 4 * 3x, 4 * 4).

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
