Teenagers signed up to be subjects in a psychology experiment. When they arrive, they are told that interviews are running
late, and they are left waiting outside. The experimenters have placed a sign next to the entry door that says, "Do not open
the door under any circumstances." Some subjects are outside alone and others are in pairs; these are the treatments being
compared. Will the subject open the door? The teenagers agreed to take part in an unspecified experiment, and the true
nature of the experiment is explained to them afterward.
Does this meet the requirement of informed consent? Explain. (5 points)
No, because they had to wait for the interviews
No, because they did not know the nature of the experiment before participating
Yes, because they agreed to participate in an experiment
Yes, because they are not forced to open the door
Unable to determine whether subjects consented to experiment

the discriminant is 64 + 4*1*12 = 112

this is prime.

step-by-step explanation:

we are given a graph for system of inequalities.

in order to write the system of inequalities for the given graph, we need to find the inequality for each of the line separately.

let us find the slope of dotted line first.

taking two coordinates on the graph.

let us say (0,0) and (3,1).

let us find the slope of the line now.

slope of the dotted line would be =.

y-intercept of dotted line is y=0 only.

plugging slope m= and b=0 in slope-intercept form y=mx+b, we get

.

the line is shaded up of that dotted line.

therefore, for shading up we would take greater than inequality symbol > .

and because it's a dotted line we would take only > symbol in place of = sign in above equation of line.

therefore, inequality for dotted line would be

let us take two points (3,1) and (0,4) on the solid line.

slope of the solid line would be =.

for the solid line we have y-intercept b= 4.

plugging slope m= -1 and b=4 in slope-intercept form y=mx+b, we get

y = -1x + 4.

the line is shaded down of that solid line.

therefore, for shading down we would take less than inequality symbol < .

and because it's a solid line we would take ≤ symbol in place of = sign in above equation of line.

therefore, inequality for solid line would be
