Simplify -|-7 + 4|. how can i do and what is the answer for it

If f(x) =3x-2 and g(x) =2x+1 fins (f+ g) (x)

Will give brainliest immeadeately true or false: the origin woud be included in the solution set for the inequality: y< 2x-5

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
