a. the residual plot for model 1 has a random pattern and is a good fit for the data.
Answer from: Quest
it's equivalent, so we can say that its equal.
let's call the denominator x and the numerador is 18 less then denominator, x - 18.
multiply
2.x = 5.(x - 18)
2x = 5x - 90
90 = 5x - 2x
90 = 3x
x = 90/3
x = 30
so:
Answer from: Quest
let's solve your equation step-by-step.
4x+2=2x+12
step 1: subtract 2x from both sides.
4x+2โ2x=2x+12โ2x
2x+2=12
step 2: subtract 2 from both sides.
2x+2โ2=12โ2
2x=10
step 3: divide both sides by 2.
2x
2
=
10
2
x=5

Answer from: Quest
answer: the angel abc is 30ยฐ,and the abc is a triangle where the angel bac is 90ยฐ
so ac is the half of 24=12ft,and from the pythagorean theorem we find ba
ba=โbc^2-ac^2=โ576-144=โ432=12โ3ft
so bac is 12+12โ3=12(1+โ3)ft
