Apotential energy function is given by u = a x3 + b x2 − c x + d . for positive parameters a, b, c, d this potential has two equilibrium positions, one stable and one unstable. find the stable equilibrium position for a = 1.45 j/m3 , b = 2.85 j/m2 , c = 1.7 j/m , and d = 0.6 j . answer in units of m

Suppose a man is heterozygous for heterochromia, an autosomal dominant disorder which causes two different‑colored eyes in an individual, produced 25‑offspring with his normal‑eyed wife. of their children, 15 were heterochromatic and 10 were‑normal. calculate the chi‑square value for this observation.

In two or more complete sentences, formulate how to use technology to calculate the appropriate regression model for the given data. you are not required to find the model, just choose the appropriate regression and explain how to use the technology.
