A is spanned by vector.
Step-by-step explanation:
The null space of matrix is set of all solutions to matrix. The linearly independent vectors forms subset which are spanned and forms the null space. The null space of vector can be found by reducing its echelon. The non zero rows formed are the null spaces of matrix.
Answer:
28/155
Step-by-step explanation:
To find people who do use the waterslide and/or the sauna subracter 43 from 155 to get 112.
To find the people who only use the sauna subtract 97 from 112 to get 15.
