Surveys can give useful information about a population if a random sample of people complete the survey. But the information may be biased if only a small percentage of the sample actually return the survey. Will more people complete a survey if they are paid? In this study researchers examine the relationship between monetary incentive and the percentage of the sample who complete the survey. The direction of this relationship is [ Select ] ["postive", "negative", "neither positive nor negative"] . In the context of this example, this means that when researchers promised higher payments, the percentage of participants who completed the survey [ Select ] ["increased", "remained the same", "decreased"] . The form of the relationship is [ Select ] ["linear", "curvilinear", "neither linear nor curvilinear"] . Based on the form of the relationship as it is illustrated above, the relationship is quite [ Select ] ["strong", "weak"] . The point (50, 64) is NOT an outlier with respect to [ Select ] ["Incentive", "Percentage returned", "Form and direction of the relationship"] .

Motor units are composed of a single nerve axon and all the muscle fibers that it innervates. True or False? I believe this to be false as my PPTs state: A motor unit consists of a GROUP of nerve FIBERS and all the muscle fibers innervated by that nerve. It also states: A motor unit consists of a SINGLE motor neuron and all the muscle fibers it CONTROLS. It is all worded differently. So I would choose false, but I am not sure if I am correct. Please explain.

(5.15) Shannon entropy. (Computer science) Natural languages are highly redundant; the number of intelligible fifty-letter English sentences is many fewer than 2^650, and the number of distinguishable ten-second phone conversations is far smaller than the number of sound signals that could be generated with frequencies up to 20,000 Hz.59 This immediately suggests a theory for signal compression. If you can recode the alphabet so that common letters and common sequences of letters are abbreviated, while infrequent combinations are spelled out in lengthy fashion, you can dramatically reduce the channel capacity needed to send the data. (This is lossless compression, used in zip, gz, and gif file formats.) An obscure language A'bç! for long-distance communication has only three sounds: a hoot represented by A, a slap represented by B, and a click represented by C. In a typical message, hoots and slaps occur equally often (p= 1/4), but clicks are twice as common (p = 1/2). Assume the messages are ot

Problem 6. (1 point) a. Find the coordinate vector for each vector in the figure. $ \vec{a} = $ $ \vec{b} = $ $ \vec{c} = $ help (vectors) help (vectors) help (vectors) b. Using geometric vector addition, draw the vector sum $ \vec{a} + \vec{b} + \vec{c} $. Then, verify your answer using vector addition operations. $ \vec{a} + \vec{b} + \vec{c} = $ help (vectors) c. Using geometric vector addition, draw the vector sum $ 2\vec{a} + 3\vec{b} - \vec{c} $. Then, verify your answer using vector addition and scaling operations. $ 2\vec{a} + 3\vec{b} - \vec{c} = $ help (vectors) d. Find the vector sum $ z_1\vec{a} + z_2\vec{b} + z_3\vec{c} $ when $ z_1 = -2 $, $ z_2 = 5 $ and $ z_3 = -5 $. You should be able to do this both geometrically and algebraically. $ z_1\vec{a} + z_2\vec{b} + z_3\vec{c} = $ help (vectors) e. Find a vector $ \vec{d} $ such that $ \vec{a} + \vec{c} + \vec{d} = \vec{0} $. You should be able to do this both geometrically and algebraically. $ \vec{d} = $ help (vectors)
