Answer:
C. No, because the subjects are randomly assigned to treatment groups
Step-by-step explanation:
We are told that 80 people are selected at random and are given the drug gabapentin.
Also that the remaining people are given the placebo.
This means that they are randomly assigned treatment groups and so it is a completely randomized block design and as such the use of volunteers doesn't make it invalid.
If the two circles are touching tangentially at one point then they have one point in common. If centers are C1 & C2 and radii are R1 & R2. then if distance C1C2 = R1+R2 then they have one point in common.
if 0< C1C2 < R1+R2 they are two points in common.
if C1C2 = 0 R1 = R2 then they have all the points in common. they are the same circle.
Look at the slope in each equation. A neg. slope indicates that the function is decreasing. A pos. slope: increasing.
