(a) Circle one: If R" contains a linearly independent set with exactly 15 vectors that is NOT a basis, then n is AT LEAST 15 / AT LEAST 16 AT MOST 14 / AT MOST 15 (b) Circle one: If R" contains a spanning set with exactly 15 vectors that is NOT a basis, then n is AT LEAST 15 / AT LEAST 16 / AT MOST 14 / AT MOST 15 (c) Circle one: If the columns of Atxa are linearly independent, then Ax = 0 has 0/1/00-many solutions (d) Circle one: If the rows of A3x5 are linearly independent, the dimension of the null space of A is 1/2/3/4/5 (e) Circle one: If the column space of A4x3 is exactly a two-dimensional plane, then the null space of A is exactly ONE POINT / ONE LINE / ONE PLANE / 3-SPACE/4-SPACE (f) Circle one: If the null space of Asx3 is exactly a plane, then the column space of A is exactly ONE POINT / ONE LINE / ONE PLANE / 3-SPACE / 4-SPACE
