As the value of k, the degrees of freedom increases, the (chisq - k)/sqrt(2k) approaches the standard normal distribution.
A skewed bell shape.
the normal distribution is a bell shape and expeonential is rectangular
Characteristics of the F-distribution1. It is not symmetric. The F-distribution is skewed right. That is, it is positively skewed.2. The shape of the F-distribution depends upon the degrees of freedom in the numerator and denominator. This is similar to the distribution and Student's t-distribution, whose shape depends upon their degrees of freedom.3. The total area under the curve is 1.4. The values of F are always greater than or equal to zero. That is F distribution can not be negative.5. It is asymptotic. As the value of X increases, the F curve approaches the X axis but never touches it. This is similar to the behavior of normal probability distribution.
skewed right.
symmetrical
Its potential energy increases as it regains its shape.
When the eccentricity of an eclipse increases, its shape becomes more elongated or elliptical. This means that the eclipse will appear less circular and more stretched out. The degree of elongation will depend on how much the eccentricity increases.
When you triple the dimensions of a flat (2-dimensional) shape,the area increases by (3)2 = 9 times.When you triple the dimensions of a solid (3-dimensional) shape,the volume increases by (3)3 = 27 times.
A skewed bell shape.
A "bell" shape.
the normal distribution is a bell shape and expeonential is rectangular
The orbit becomes more eccentric until the orbit becomes almost a strait line.
The distribution of the sample mean is bell-shaped or is a normal distribution.
The standard normal distribution or the Gaussian distribution with mean 0 and variance 1.
