A company performs linear regressions to compare data sets for two similar products. If the residuals for brand A are randomly scattered above and
below the x-axis, and the residuals for brand B form a U-shaped pattern, what
can be concluded?

the discriminant is 64 + 4*1*12 = 112

this is prime.

step-by-step explanation:

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)
