Determine Whether the Variation Model Is of the Form $y = k x$

question 28

Multiple Choice

Determine whether the variation model is of the form $y = k x$ or $y = \frac { k } { x }$ and find k.Then write a model that relates y and x. $$\begin{array} { | c | c | c | c | c | c | } \hline x & 4 & 8 & 12 & 16 & 20 \\\hline y & 1 & \frac { 1 } { 2 } & \frac { 1 } { 3 } & \frac { 1 } { 4 } & \frac { 1 } { 5 } \\\hline\end{array}$$

• A) \(y = 4 x\)
• B) \(y = \frac { 1 } { x }\)
• C) \(y = \frac { 4 } { x }\)
• D) \(y = x\)
• E) \(y = \frac { x } { 4 }\)

Definitions:

Polygenic

A term describing traits or disorders influenced by multiple genes, typically resulting in a continuum of possible phenotypic outcomes.

Codominant

A genetic scenario where two alleles of a gene pair in a heterozygote are fully expressed, with neither being recessive to the other.

Dominant

Possessing authority, control, or influence over others, often in a social, genetic, or interactional context.

Dizygotic Twins

Also known as fraternal twins, they develop from two different eggs fertilized by two different sperm, resulting in genetically unique siblings born at the same time.
