To find the total number of diagonals for any given polygon, you can use the expression n(n-3) divided by 2, where n is the number of sides of the polygon

a) determine the minimum value that n could be
b) make a table of four possible values of n. then complete the table by evaluating the expression for each value of n.
c) check by drawing the diagonals of a pentagon and counting the diagonals

Can someone show me the steps to solve the problem?

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
