The percentage varies according to race. About 85% of Americans have Rh+ blood. In China, the percentage is over 99%. The worldwide percentage is about 90%.
85% positive - 15% negaive
This varies tremendously by region of population movement over centuries, from under 5% in North and South America; to 15-25% in most areas of Asia and the Middle East. Worldwide, 29.98% of the population is type B, which include B positive and B negative blood types.
In an electromagnet, the negative side of the coil is said to "emit" the magnetic field lines- it is the north pole of the electromagnet. However, in alternating current, the energized wire alternates between positive and negative. As a result, a conventional electromagnet running on alternating current would constantly be undergoing a reversal of the poles.
velocity is a vector quantity and also acceleration is a vector quantity. Suppose my automobile is travelling in north direction and I apply brakes to it then until the automobile stops it will move in north direction while the acceleration will act in south direction as brakes are applied.
Although transfusion errors are only a small percentage of all medical errors reported in North American hospitals, they are the most common cause of serious mortality and morbidity associated with blood transfusions

North/south and negative/positive have nothing to do with each other.
No it is a positive number, because there are two negative signs you cancel them. For example: 9-(-4)=13 Since there is a parenthesis between both signs (parenthesis means to multiply) you multiply. Negative X Negative = Positive; then the -4 becomes positive and finally you just add. Very complex isn't it. Think about it like this. Say you're in a car on a North-South road. North is positive, and South is negative. If you're a positive number, then point your car North, if a negative, point your car South. Now if you are to be added, then drive forward, and if you are to be subtracted, then put in reverse and drive backward. So in the above example, start at 9 miles North of a reference point (mile zero). Then you are negative 4, so point the car South, but since you are subtracting, drive in reverse for 4 miles (you will be moving toward the North, which is in the positive direction), and arrive 13 miles North of the reference point (positive 13). Hope this helps.
If you define one direction (for example, north) as positive, then the opposite direction is negative.

The answer to that question could be "south", "negative", "positive" "Lech Walesa", or "north", depending on what "it" is.

Magnet declination is the angle between magnetic north and true north. Declination is considered positive east of truth north and negative when west.
polar opposites attract. that's where the phrase "opposites attract" comes from.AnswerThere are no such things as 'positive' or 'negative' magnets, other than in the minds of magnetic therapists who seem to have very little scientific knowledge of magnetism! Magnetic poles, not magnets, are named after the directions in which the point when freely suspended -i.e. north and south.
