A single curve cannot touch "each other" since "each other" implies two curves.
They can, so the question is irrelevant.
The domain of the Normal distribution is the whole of the real line. As a result the horizontal axis is asymptotic to the Normal distribution curve. The curve gets closer and closer to the axis but never, ever reaches it.
because it is imposible
This is because the normal distribution has a domain that extends to infinity in both directions.
The normal curve, or Gaussian distribution, approaches but never touches the axis because it is defined mathematically to extend infinitely in both directions. As you move further away from the mean, the probability density decreases, but it never actually reaches zero; instead, it asymptotically approaches the horizontal axis. This characteristic reflects the fact that while extreme values become increasingly unlikely, they are still possible, ensuring that the total area under the curve remains equal to one.
Tangent to the curve.
no
I have the Blackberry Curve 9320 and it is NOT a touch screen.
No. Sorry!
Well it depends which one you get, the newest one is-9900 and I have a feeling the 9790 is.
What is MPN product description for an ipod touch?
The tangency condition refers to the point where a curve and a straight line touch each other without crossing. At this point, the curve and the line have the same slope. This affects the behavior of the curve at the point of tangency by creating a smooth transition between the curve and the line, without any abrupt changes in direction.
