01.06.1 Multiple-Choice Test Chapter 01.06 Propagation of Errors 1. If 05 . 0 56 . 3 ± = A and 04 . 0 25 . 3 ± = B , the values of B A + are (A) 90 . 6 81 . 6 + B A (B) 90 . 6 72 . 6 + B A (C) 81 . 6 81 . 6 + B A (D) 91 . 6 71 . 6 + B A 2. A number A is correctly rounded to 3.18 from a given number B . Then C B A , where C is (A) 0.005 (B) 0.01 (C) 0.18 (D) 0.09999 3. Two numbers A and B are approximated as C and D , respectively. The relative error in D C × is given by (A) × B D B A C A (B) × + + B D B A C A B D B A C A (C) × + B D B A C A B D B A C A (D) B D B A C A 4.
