A two-dimensional robot arm "knows" where it is by keeping track of a "shoulder" angle a and an "elbow" angle B. As shown in the figure, this arm has a fixed point of rotation at the origin. The shoulder angle is measured counterclockwise from the x-axis, and the elbow angle is measured counterclockwise from the upper arm to the lower arm. Suppose that the upper and lower arms are both of length 2 and that the elbow angle B is prevented from "hyperextending" beyond 180°. Find the angles a and ß that will position the robot's hand at the point (1, 2). (Round your answers to two decimal places.) a =

A ✩ The box-and-whisker plot below represents the length, in inches, of 20 trout caught at Raystown Lake in one weekend. 4466619/varlants/5145485/take/5/ 10 Length of Trout (inches) H 15 20 H 25 30 How many trout were less than 20 inches long? Hint: 20 inches is the upper quartile of the box-and- whisker plot. So, 75% of the trout were less than 20 inches long. To find the answer: multiply the percentage (75%) x 20 (the number of inches) We use 75% because that is the Q3 in the data. 25% would be our Q1 and 50% is the median (or Q2).
