Consider diffusion inside an enclosed circular tube. let its length (circumference) be 2l. let x denote the arc length parameter where -l lessthanorequalto x lessthanorequalto l. then the concentration of the diffusing substance satisfies: {u_t = ku_xx -l < x

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 points (1, 7) and (0, 2) fall on a particular line. what is its equation in slope-intercept form?

In the diagram, ab is tangent to c, ab = 4 inches, and ad = 2 inches. find the radius of the circle.
