A technician works overtime one out of four days. He listens to the radio one out of eight days while driving to work, Assuming working overtime and listening to the radio driving to work are independent events, what is the probability
that he works overtime and listens to the radio driving to work tomorrow? Give your answer as an exact fraction and
reduce the fraction as much as possible.

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)

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.

step-by-step explanation:

the answer to this is a. a^2 + b^2 = c^2

hint: which coefficient is a multiple of 360°?
