Two of the airlines did not have an airline quality score. The least-squares regression line for this data is given by ŷ = 0.990

+ 0.683 x. (Let x = passenger complaint rank and y = airline quality score.) Use the least-squares line to predict the airline quality score for Hawaiian Airlines and Northwest Airlines. (Round your answers to three decimal places.)

Answer:

Step-by-step explanation:

the passengers of  hawaiian airlines  in 2018 were 1.800.000, and for Northwest airlines 192.500.000 (delta)

We replace this number in the equation :

Hawaiian : 0,990 +0.683 x (number of passengers) =

                  0.990 + 0.683 x (1.800.000) =12294012

Northwest airlines: 0,990 +0.683 x (number of passengers) =

                  0.990 + 0.683 x (195.000.000) = 131477501

Marcus was going up 10 stairs in his office. Write an absolute value expression for the given statement.
djyliett [7]

The absolute value expression for the given statement is  |10|

<h3>What is absolute value?</h3>

The absolute value (or modulus) | x | of a real number x is the non-negative value of x without regard to its sign

Marcus was going up stairs in his office. Therefore, he was ascending .

This means the 10 staircase will be added since there is an increase.

Hence, the absolute value expression for the given statement is as follows:

absolute value = |10|

A pilot was scheduled to depart at 4:00 pm, but due to air traffic, her departure has been delayed by 10 minutes. Air traffic co
Greeley [361]

Answer:

Y= X/3 + 10

Step-by-step explanation:

The initial time of departure = 4.00pm

Her flight was then delayed for 10 minutes

Let the initial flight plan be X

Let the new flight plan be Y

The new flight plan allows her arrive at her destination three times faster. this means Y = (1/3)X

Y = X/3

The equation to know the number of minutes after 4.00pm she will arrive is

1/3 of the initial plan + the 10 minutes of delay

Y = X/3 +10
