A farsighted eye is corrected by placing a converging lens in front of the eye. The lens will create a virtual image that is locatedat the near point (the closest an object can be and still be in focus) of the viewer when the object is held at a comfortabledistance, usually taken to be 25.0 cm. If a person has a near point of 79.5 cm, what power reading glasses should be prescribedto treat this hyperopia? Assume that the distance from the eye to the lens is negligible.power:0.0275Incorrect.diopters

According to the given data, find the power of the lens:

A EXAM #2 IE 3477 Methods and Industrial Engineering March 11, 2021 1. (20 points total) A guard rail at the front row of the second deck of a sports stadium is 85 cm. high. When someone sits back normally in a seat with a seat back in that section, the angle between the eye and the near edge of the playing field is 35 degrees below horizontal. The height of the seat was designed based on an average male. Assume that the horizontal distance from the eyes of a person seating to the edge of the guard rail is 1.15 mts. Determine what percentage of the female population may be able to see the near edge of the playing field over the rail. ANSWER:
List a value of X in quadrant ii that makes csc(x)=2 . Explain how you got your answer.
Alligators have shown the ability to determine the direction of an airborne sound. But can they locate underwater sounds? This was the subject of a study. Alligators were monitored for movement toward a sound produced from a submerged diving bell. Movements within a 180° arc of the direction toward the sound were scored as movements toward the sound; all movements in other directions were scored as movements away from the sound. Consequently, the researchers assumed that the proportion of movements toward the sound expected by chance is 180°/360° = 0.5. In a sample of n= 50 alligators, 29 moved toward the underwater sound. Complete parts a through e below. a. Give the null and alternative hypotheses for testing whether the true proportion of alligators that move toward the underwater sound is higher than expected by chance. Let p be the true proportion of alligators that move toward the underwater sound. Choose the correct answer below. O A. Ho: p>0.50 vs. Ha: p= 0.50. O B. Ho: p= 0.50…
