A common definition of "binge drinking" is consuming 5 or more drinks at one setting for men, and 4 or more for women. An observational study finds that students who binge drink have lower GPAs, on average, than those who don't. However the possibility of confounding means that we can't conclude that increased alcohol consumption causes lower GPA. Select any possible lurking variables that may be confounding the relationship between binge drinking and GPA:

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

6 cm

step-by-step explanation:

the easiest way to do these would be to solve the equations. if you can solve the equation than you can solve these problems.
