Tina’s application for graduate school was ranked 54 out of 300 applications. Her twin sister’s application to a different graduate school was ranked 23 out of 175 applications. a. Which sister had the higher percentile ranking?

B. If you had the data on the cumulative GPA of each student in each school in June 2019, which measure of average would be the most meaningful – mean, median, mode? Explain.

if you was gonna solve for a, a is a   < -12

think the answer would beb

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
