No, a normal distribution has only one mode. A bimodal distribution is not normal, but it can indicate the possibility of two underlying normal distributions.

A normal distribution approximates a bell-shaped curve. Outliers to one side would skew the distribution. If the distribution was flat, having about the same frequencies throughout the distribution, this would be non-normal. Also a bimodal distribution would be non-normal, ...

math
using distance from (2,1/2) to y=x^2, d^2 = (x-2)^2 + (y-1/2)^2 = (x-2)^2 + (x^2 - 1/2)^2 = x^2 - 4x + 4 + x^4 - x^2 + 1/4 = x^4 - 4x + 17/4 d = sqrt(x^4 - 4x + 17/4) d' = 2(x^3 - 1)/sqrt(x^4 - 4x + 17/4) d' = 0 when x = 1 so, (2,1/2) is closest to (1,1) ______________________...

Physics
Normal means perpendicular to the slope. The slope is at X deg to the horizontal, and the normal is 90 deg to that, so to the horizontal, the normal then is 90+x, but measuring the normal to the perpendicular, you subtract 90, so the normal is to vertical is X deg. gravity is ...

Math
Do you believe the distribution would be normal or skewed? If it is normal, it doesn't make a difference. If skewed, the mean is most influenced by deviant scores, so the median is a better indicator of central tendency.

Chemistry
Vitamin K is involved in normal blood clotting. When 2.40 g of vitamin K is dissolved in 25.0 g of camphor, the freezing point of the solution is lowered by 8.05 C. Calculate the molar mass of vitamin K. Kf value is 37.8 and the normal freezing point is 176 degrees C

Chemistry
What is the normal boiling point of water? Isn't it 100 degrees C. So if 4a is a California beach at sea level, then atmospheric pressure is 1 atmosphere (760 mm Hg)so 4b would be the normal boiling point of water which is 100 C.
