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
hjlf

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

If jl = 5x+2, find jl<br> please help me answer please this is urgent
Olenka [21]

Answer:

JL = 62

Step-by-step explanation:

JL = JK + KL, substitute values

5x + 2 = 27 + 3x - 1

5x + 2 = 26 + 3x ( subtract 3x from both sides )

2x + 2 = 26 ( subtract 2 from both sides )

2x = 24 ( divide both sides by 2 )

x = 12

Thus

JL = 5x + 2 = 5(12) + 2 = 60 + 2 = 62
