Suppose the Weights (In Grams) and Lengths (In Centimeters) of Three

Multiple Choice

Suppose the weights (in grams) and lengths (in centimeters) of three groups of laboratory animals are given by matrix A, where column 1 gives the lengths and each row corresponds to one group. ​ ​
​
If the increase in both weight and length over the next two weeks is 12% for group I, 5% for group II, and 3% for group III, then the increases in the measures during the 2 weeks can be found by computing GA, where
