What does the analysis of variance procedure compare to determine whether the population means are equal? a. the between-treatments estimate of σ2 and the within-treatments estimate of σ2 b. the sample proportions c. the population means d. the population variances and the sample variances

i think it's b

step-by-step explanation:

because the graph is 2 above (0,0)

eve and marks ratios are equivalent

step-by-step explanation:

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
