What is the equation of the parabola shown below, given a focus at F(1, 5) and a directrix of x = −3? In addition, identify the vertex and the equation of the axis of symmetry for the parabola. vertex: (−1, 5), axis of symmetry: y = 5 vertex: (5, −1), axis of symmetry: x = −3 vertex: (−2, −5), axis of symmetry: y = 2 vertex: (−1, 5), axis of symmetry: y = 5

Assume that there is a 11% rate of disk drive failure in a year. a. if all your computer data is stored on a hard disk drive with a copy stored on a second hard disk drive, what is the probability that during a year, you can avoid catastrophe with at least one working drive? b. if copies of all your computer data are stored on four independent hard disk drives, what is the probability that during a year, you can avoid catastrophe with at least one working drive?
