This draft confuses the usual, explicit definition of functions with algorithmic definitions. For example, the function on the real plane that takes (a,b) and returns 1 when a< b or returns 0 otherwise, where < is a well-ordering on the reals given by the axiom of choice, is certainly not algorithmic.
An average full-grown male Labrador Retriever weighs anywhere between 65 and 80 lbs. Males are characteristically larger than females, though are just as prone to becoming overweight. The average female Labrador Retriever can weigh from 55 to 70 lbs, depending on bone structure and diet.
So average Labrador Retriever weight figures can be misleading. As a very rough guide an adult female Labrador might weigh between 55 and 70lbs. An adult male Lab will weigh 65 â 80lbs. Female Lab weight will on average be lower than male Lab weight, but as you can see there is a considerable cross over.
