mr. crandall has assigned a term paper due at the end of the semester. he would like to know the average length of the paper. the data below are the numbers of typed pages from a random sample of 10 term papers. use the data to create a 98% confidence interval for the population mean length of all term papers for his class.

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:

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft

here's a poem i finished a while ago. i hope you like it and that it inspires you.
