The level of production at which a firm neither makes a profit nor sustains a loss is called the break-even level of operation. 3. The matrix product AB is defined if and only if the number of columns of matrix A is equal to the number of rows of matrix B. 4. Let A and B be finite sets such that AnB Ø. By the addition rule for sets, we have n(An B) = n(A) + n(B). 5. The number of combinations of n distinct objects taken n at a time is C(n.n) = n!. 6. If a linear programming problem has a solution, then it must occur at a point on the border of the feasible set S. 7. The objective functions of both the primal and dual problem attain the same optimal value. 8. Simple interest is earned interest at an interest rate of r (in dollars) per year for t years that is computed on the original principal only. 9. A arithmetic progression is completely determined if the first term and the common difference are known. 10. The sum of the first n terms of a geometric sequence with first term a and common ratio r = 1 is given by S₁ = 1-r
