Ms. Park printed out pages to make a handout. She then realized she wanted to teach scholars about a few more poems so she added 3 more pages to the handout She then made 15 copies, and ended up with 75 total pieces of paper . How many pages, p, were in the original handout before she added more? Write an equation to represent the situation and then solve

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

The product of 3 and a number increased by 8 is 31 written as an equation

Nour and rana are shopping for a christmas tree. they are deciding between 2 22 different types of trees (real and fake) and 4 44 colors for the ornaments (white, silver, gold, and purple). they each created a display to represent the sample space of randomly picking a type of tree and a color for the ornaments. whose display correctly represents the sample space?
