An art supply store sells calligraphy pens at Sp per pen and calligraphy ink at $q per bottle. The price of one affects the price of the other, and the weekly demands, x and y, are each functions of p and q given by the given contour diagrams, where x = C(p.q) gives the quantity demanded of pens and y = 1(p.q) gives the quantity demanded of calligraphy ink. Complete parts a) and b) below. W Click the icon to view the contour diagrams. a) What does the graph of x= C(p,g) indicate about the values of dp At any value of p and q on the graph of,

Problem YOUDEN RECTANGLE'S PROBLEM BIBD- Balanced Incomplete Block Design . There is a matrix m x n. This matrix can be 26 x 4 but we can change this dimension if 26 x 4 does not admit a feasible solution. • m> n + 1 • The rows are called "blocks" and the columns are called "forms" • Every form is composed by the same number of blocks • • Every block is composed by the same number of forms The matrix is full and every single spot should be filled with a treatment Every treatment is is replicated r times in the Youden rectangle • Every treatment appears in every form maximum one time • Every couple of treatment appear together in every form 1 times Every treatment appear in all single blocks the same number of times v = number of treatments (1,2,3,4,.....,n) n = blocks (columns) m = forms (rows) r = number of times every treatment is replicated λ = number of times two treatment appear together in the same form Constraints: 1) nxm=vxr - 2) 1 (v 1) = r (k-1) 3) m > v then r > n Goal The…
