The least common denominator of the two fractions is 30. if you add the two denominators, their sum is 17. what are the denominators

Find the area of the regular hexagon if a side is 20 cm.

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

Find the solution set for this equation: t^2+7t=0 separate the two values with a comma.
