Function or not a function?

The angle of a triangle are given as 6x,(x-3), and (3x+7). find x then find the measures of the angles

Ab based on the given diagram, if m_1 = 60° then m 2 = 30 60 90 180

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
