Choose the statement that is true. a. For a normal distribution, 68% of the distribution is within 3 standard deviations.
b. For a normal distribution, 100% of the distribution is within 3 standard deviations.
c. For a normal distribution, 99.7% of the distribution is within 3 standard deviations.
d. For a normal distribution, 95% of the distribution is within 3 standard deviations.

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

i belive those are the ones that are under 90 degreese.

won't that be plagrisim thought?

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.
