## 1. Nonnegativity and Exact Total One as Separate Weight Tests

Use a finite nonempty ordered vector list and aligned exact rational weights. Convex weights may be zero but must be nonnegative and sum exactly to 1, not merely approximately. A convex-combination witness establishes its weighted point, not unique coordinates without separate affine independence. vectors=[[-12, 0], [-10, 2]], weights=[2/3, 2/3]. This family admits unqualified candidates for inspection. Give (vectors,normalized weights,all nonnegative?,exact sum,sum equals 1?,both conditions?). Use exact rational arithmetic, reduce fractions to positive denominators and omit /1 for integer outputs.

View answer and explanation([[-12, 0], [-10, 2]], [2/3, 2/3], Yes, 4/3, No, No)
