Carly surveys students at her school to find out if there is an association between grade level and favorite core subject. Of the 7th graders responding to the survey,
she found that 25 prefer science, 17 math, 6 ELA, and 19 social studies. Of the
8th graders responding to the survey, she found that 12 prefer science, 20 math,
14 ELA, and 17 social studies.
Part A
Make a two-way table to display the results of the survey.

b. 153 students do not participate in sports and seventy-five 12th graders were surveyed

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.
