Answer:An expression is one or more terms in an algebraic phrase. An expression does not contain the = sign because it is a phrase. Some examples of algebraic expressions are 2x, 5x + 3, 8m - 5m + 10

Evaluate an Algebraic Expression

To evaluate an algebraic expressiontext annotation indicator for x = 3, means to replace the variable x with the number 3 and then simplify by following order of operations.

Example:

Evaluate the following expression for x = 3.

3 xtext annotation indicator + 5

3(3) + 5text annotation indicator

= 9 + 5

= 14

Write an Algebraic Expression

To write an algebraic expression, look for key words that tell you what operation (add, subtract, multiply, or divide) to use.

Example:

Write an algebraic expression for: The product of x and 5 .

The key word here is product . You may recall that a product is the answer obtained when you multiply. That means we want to multiply x and 5, so we write the expression as 5 x . It should be written the standard way by putting the coefficient in front of the variable.

Step-by-step explanation:

madreJ [45]

The answer is 30+6x you would just multiply 6 by 5 then put 6 next to x.

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

= $132+0.81(42)\\= 166.02$

Which values are solutions to x<16?

leonid [27]

Answer:

Option D.

x can take values from 15downwards. It can't be 16 because the expression clearly states that x is less than 16. So x can take value from any number below 16.
