The level of calcium in the blood of healthy young adults follows a Normal distribution with a mean of LaTeX: \mu = 10μ = 10 milligrams per deciliter and a standard deviation of LaTeX: \sigma = 0.4.σ = 0.4. A clinic measures the blood calcium of 100 healthy pregnant young women at their first visit for prenatal care. The mean of these 100 measurements is LaTeX: \bar x= 9.8x ¯ = 9.8. Is this evidence that the mean calcium level in the population of healthy pregnant young women is less than 10?

no i do not : ( what is it?

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:

25/14 or 1.

step-by-step explanation:

the dots mean that it has infinitely more numbers behind it

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative
