You need to find the width of the stream. you cannot measure the width directly, so you draw a diagram showing lengths that you can measure. your diagram contains two similar triangles, one in the stream and one on land. use the diagram to find the width of the stream. math item stem image

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
