Given the system of equations presented here: 3x + 5y = 29 x + 4y = 16 which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? a) multiply the second equation by −1 to get −x − 4y = −16 b) multiply the second equation by −3 to get −3x − 12y = −48 c) multiply the first equation by −1 to get −3x − 5y = −29 d) multiply the first equation by −3 to get −9x − 15y = −87

The fraction of defective integrated circuits produced in a photolithography process is being studied. a random sample of 300 circuits is tested, revealing 17 defectives. (a) calculate a 95% two-sided confidence interval on the fraction of defective circuits produced by this particular tool. round the answers to 4 decimal places. less-than-or-equal-to p less-than-or-equal-to (b) calculate a 95% upper confidence bound on the fraction of defective circuits. round the answer to 4 decimal places. p less-than-or-equal-to
