For the remaining questions, consider the following problem description:An oil company is considering exploring new well sites S₁, S2, ..., S10 with respective costsC1, C2, C10. And in particular they want to find the least-cost selection of 5 out of the 10 possiblesites. The binary decision variables x₁,x2,..., X10 denote the decision to explore the correspondingsite. ntsnsProvide the best interpretation of the constraint:OX3 + X5 ≤ 1X₁ + X5 ≤ 1Exploring site S3 or site S4 prevents you from exploring site S5OExploring site S3 requires exploration of S4 or S5Exploring sites S3, S4, and S5 is only possible if another constraint is disjunctiveExploring the combination of sites S3 and S4 prevents you from exploring S▸4

In the context of optimization problems, a constraint is a condition or limitation that restricts…

7.) 7.) which of the following describes a direct relationship between and independent and a dependent variable, after controlling for a third variable? a. the bivariate relationship changes acress the partial tables. b.one partial table is the same as the bivariate table, the other(s) are very different c. the bivariate realtionship is the same across the partial tables d. the partial tables have many empty cells.
f. A drapper is required to supply two types of shirts type A and type B. The total number of shirts must not be more than 400. He has to supply more of type A than type B. However, the number of type A must not be more than 300 and the number of type B shirts must not be less than 80. Let x be the number of type A shirts and y be the number of type B shirts. If the profits were as follows: Type A Ksh 600 per shirt Type B Ksh 400 per shirt. Formulate a Linear Optimization Model, hence use the graphical method to determine the number of shirts of each type that should be made to maximize the profit.
The monthly income associated with the sale of two products is described with the function in two variables / = 21a + 19b, where a and b are quantities sold of products A and B, respectively. Furthermore, it is known that the cost of producing these products is modeled by C = 3a² +6b². With this information answer: Write the criterion of the monthly profit function from the sales of products A and B, use as variables a and b What is the only critical point of the utility function? What is the value of the discriminant of the utility function evaluated at that critical point (Value of D used to classify the critical point) At this critical point. Is a relative maximum, a relative minimum, or neither determined?
