There are 10 players and 7 chairs. How likely is it that I will win
this round?

70%

Step-by-step explanation:

To solve this problem, you simply divide 7 by 10.

7 ÷ 10 = .7

.7 is the decimal form of 70%. This means that you have a 70% chance of winning this round.

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.
