The sample proportions, , who approve the president within all possible samples of this size. A confidence interval containing the true proportion of voters who approve of the president. The proportion of all voters who approve the president. The proportion of these 3,500 voters who approve the president.

stethere all not eveanp-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.
