Scores of an iq test have a bell-shaped distribution with a mean of 100 and a standard deviation of 15. use the empirical rule to determine the following.
(a) what percentage of people has an iq score between 55 and 145?
(b) what percentage of people has an iq score less than 55 or greater than 145?
(c) what percentage of people has an iq score greater than 145?

y -5 = (-1/4)(x + 8)

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.
