A quadratic function is defined by f : [6, 1]  ℝ and rule f(x) = ax2 + bx + c.

The turning point has coordinates (1, 10). The minimum value of the function is 10. Find the values of a, b and c.

Find an equation of the line perpendicular to the graph of 28x-7y=9 that passes through the point at (4,1)

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
