The average sale price of new one-family houses in the united states for 2003 was $247,900. findthe range of values in which at least 75% of the sale prices will lie if the standard deviation is$51,500. round your k to the nearest whole number. the range of values is between $ and $

just sum

10 + 10 = 20

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.
