Afair coin is flipped 3 times. it lands facing heads up 2 out of 3 times.
the probability of a fair coin landing heads up on one flip is 1/2. select the statement that gives
the most likely explanation for why the observed frequency is different than the predicted
probability.

a. the kind of coin used is too heavy.
b. the coin had heads on both sides.
c. the total number of coin flips is small.
d. the probabilities 1/2 and 2/3 have
different denominators.

not enough information

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.

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.
