Solve and check: 3 x2 + 5x + 6 + x − 1 x + 2 = 7 x + 3 x = is a solution. x = is an extraneous solution.

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

Complete the solution of the equation. find the value of y when x equals to 28 x+3y=28
