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 =

Contingency Table

A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.

Binomial Distribution

Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.

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).
* Subscribe An object is thrown in the air with vertical velocity of 20 ft/s and horizontal velocity of 15 ft/s. The object's height can be described by the equation y (t) = -162+20t while the object moves horizontally with constant velocity 15 ft/s. Write parametric equations for the object's position, and then eliminate time to write height as a function of horizontal position. How did you arrive at your conclusion(s) for this problem? *Provide your initial post, read posts from your classmates, and contribute to the discussion by responding (with a minimum of 3 sentences). You may collaborate together to complete the solution. Your response should be well thought out and further the discussion. Use the graphical equation editor when necessary to express your answer.
