Based on a sample survey, a principal claims that 7 out of 10 students like math. If there are 1300 students, how many would you predict do NOT like math?

390

Step-by-step explanation:

find the fraction of those that don't like math

10/10 - 7/10= 3/10

then do 3/10 x 1300 to get 390

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.
