An srs of 25 recent birth records at the local hospital was selected. in the sample, the average birth weight was =119.6 ounces. suppose the standard deviation is known to be =6.5 ounces. assume that in the population of all babies born in this hospital, the birth weights follow a normal distribution, with mean based on the 25 recent birth records, the sampling distribution of the sample mean can be represented by:

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )

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.
