algebra_poly_eval_v1_1419126231_1203
A digital artist generates images using binary sequences of length $320$. An image is considered *high-contrast* if the number of ways to choose $j$ pixels to highlight is odd. Let $R$ count how many values of $j$ from $0$ to $320$ produce such images. Separately, a chemist mixes compounds $A$ and $B$ in integer amount...

comb_count_permutations_fixed_v1_1218484723_1661
A teacher assigns 7 students to present topics, ensuring no one gets their own preferred topic. She selects one student to assign first (in $\binom{7}{1}$ ways), then assigns the remaining 6 students to topics such that none receives their own, in $D_6$ ways. Let $N$ be the total number of such assignment sequences. Co...
