The diagram shows a telescope fitted with parabolic, hyperbolic, and elliptical mirrors. The focus of the parabola coincides with one of the foci of the hyperbola. The second focus of the hyperbola coincides with one of the foci of the ellipse, and the other
focus of the ellipse is located at the eyeplece. A ray of light parallel to the parabolic axis enters the telescope, as shown, and
hits the parabolic surface.
Draw lines on the dlagram to show how the light ray will be reflected by each conic surface.

(co 3) the times that customers spend in a book store are normally distributed with a mean of 39.5 minutes and a standard deviation of 9.4 minutes. a random sample of 25 customers has a mean of 36.1 minutes or less. would this outcome be considered unusual, so that the store should reconsider its displays? no, the probability of this outcome at 0.035, would be considered usual, so there is no problem yes, the probability of this outcome at 0.035, would be considered unusual, so the display should be redone no the probability of this outcome at 0.359 would be considered usual, so there is no problem yes, the probability of this outcome at 0.965 would be considered unusual, so the display should be redone
