A biologist measured the length and mass of 20 rep length, in centimeters, and \( y \) is the mass, in grams. Based on the equation, what is the approximate len A. 62 cm B. 66 cm C. 70 cm D. 75 cm

To determine the approximate length that corresponds to a specific mass based on the equation from the biologist's measurements, it's essential to evaluate the relationship established in the data. Although we haven't been given the exact equation, typically linear regressions are used in biology to model such relationships. You can estimate the length by substituting a value from the given mass into the equation and solving for the length \( x \). Once you analyze the available options and substitute them into the equation, the most accurate choice resulting from your calculations will lead you to the correct answer, which should take into consideration the growth patterns typical for those species.
