You may have polarized sunglasses that eliminate glare by polarizing the light. when light is polarized, all of the waves are traveling in parallel planes. suppose vertically polarized light with intensity io strikes a polarizing filter with its axis at (theta) with the vertical. the intensity of the transmitted light it and theta are related by the equation cos= the square root of it/io. theta is 45 degrees. write it as a function of io.

For f(x)=2x+1 and g(x)= x^2 -7, find (f•g)(x)

2y= 3 2 x−2 y = − 1 3 x + 1 y=− 3 1 x+1

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
