What happens when two polygons have the same z value and the z-buffer algorithm is used?
the pixel intensity in final image will be of the surface last scanned if the z value is same.
What does it mean for a negative to be decreased by a negative?
It becomes less negative
To explain. Lets take a negative, eg -5.
If we decrease it by 1, it becomes -6 (where 1 is positive)
Thus if we decrease it by -1, it becomes -4 (as the -1 is negative)
Note that the final number could be positive,
For example, if you decrease -5 by -6, you get +1

To cut the maximum likely error in half the sample size should be?
... should be increased by a factor of 4. Note that this implies that the only errors are statistical (random) in nature; increasing the sample size won't improve systematic errors.

Anuzinc suppository dose frequency?
"Directions: Remove wrapper and insert one suppository into the rectum in the morning and at bedtime, and after each bowel movement."
Negative correlation implies an inverse relationship between a person's weight and the amount of distance that they walk (say on an average day). So you can conclude that heavier people are more likely to walk less. Lighter people are more likely to walk more.
Remember though that correlation does not always equate to causation. What this means in practical terms is that walking more does not necessarily mean you'll lose weight. Conversely, walking less does not necessarily mean that you'll gain weight. Or thinking of it another way, losing weight will not necessarily cause you to walk more and gaining weight will not necessarily cause you to walk less.
