Weighted average grade: The weighted grade is equal to the sum of the product of the weights (w) in percent (%) times the grade (g): Weighted grade = w 1 Ã g 1 + w 2 Ã g 2 + w 3 Ã g 3 +...When the weights are not in percent (hours or points...), you should also divided by the sum of the weights:Weighted grade = (w 1 Ã g 1 + w 2 Ã g 2 + w 3 Ã g 3 +...) / (w 1 + w 2 + w 3 +...).hen the weights are not in percent (hours or points...), you should also divided by the sum of the weights: Weighted grade = (w 1 Ã g 1 + w 2 Ã g 2 + w 3 Ã g 3 +...) / (w 1 + w 2 + w 3 +...).
A pinched nerve is a nerve with pressure applied to it, in terms of a whiplash injury this is usually caused by a herniated disc pressing against it. Pinched nerves in the spine tend to happen in the neck and lower back as these are the areas that do the most moving.The symptoms of a pinched nerve include weakness, tenderness, prickly sensation, tingling sensation or stabbing sensations in the limbs or areas of the body where the nerves are linked to.n this case the âdiseaseâ in question is the pressure applied to the nerve from a herniated disc as a result of the extreme forces applied to the neck from a whiplash type injury. Treatment for this is the same as that for a herniated disc or possibly a fractured vertebrae, as they are the root cause of this condition.
Some of the areas where pinched nerves most frequently occur include: 1  The sciatic nerve, which can cause pain through the lower back and into the leg. 2  The cervical spine, better known as the neck region of the back. Pinched nerves in the neck can cause radiating pain through the shoulder blade and/or arm.
