Question 6 of 10
2 Points
At City Community College, every freshman must take Math 101. The math
department wants to know whether students who take this class in their
second semester get better grades than students who take the class in their
first semester. Which principle of experimental design can the math
department best use to include a variety of students in both the first and
second semester treatment groups of the study?

$30.32

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316

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.

i would say true? if the unit was informational and it "refreshed your understanding", then true.
