Use quadratic regression to find a function that fits the following
points
(1,-8), (2,-4), (3,6)

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.

the probability that a bird is green (.30) is true

step-by-step explanation:

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
