Question

In mammals the weight of the heart is approximately 0.5%. Write a linear model that gives the heart weight in terms of whole body weight?

Answer 1

Answer: $h=0.05w$

Let the whole body weight of a whale be w

Let the weight of the heart be h

It is given that weight of the heart is 5% weight of the whole body weight.

$\Rightarrow h=5 \% \hspace{1mm} of \hspace{1mm} w\\ \Rightarrow h=\frac{5}{100}\times w\\ \Rightarrow h=0.05w$
