A teacher compiles a data set from the records in one of his 7th grade history classes. The final exam in the course is a 20-item multiple choice test, with each test item worth 5 points (no partial credit given). So scores on the final exam can range from 0 to 100. The data he compiles include the student’s name, ID number, gender (coded 0 for male, 1 for female, 2 for other), final exam score (on a 100-point scale), and course grade (as a letter grade).  Example data for two students are given below. Name ID Gender FinalExam Grade Mary 23994 1 95 A Ali 27114 0 85 B+   Give the level of measurement for each of the variables above, using the categories {nominal, ordinal, interval, ratio}. Name:  [LM1] ID:  [LM2] Gender:  [LM3] FinalExam:  [LM4] Grade:  [LM5]  

Find an equation of the tangent line to the curve at the point. You may leave your answer in point-slope form. x=t2−5,y=2t3+6,(−1,−10){“version”:”1.1″,”math”:”x = t^{2}-5,\, y = 2t^{3}+6, \quad{} (-1,\, -10)”}

Given the parametric equations . Eliminate the parameter and write the corresponding rectangular equation. Do not use inverse trigonometric functions in your answer. x=2cos⁡(t),y=3sin⁡(t)−2{“version”:”1.1″,”math”:”x = 2\cos(t),\, y = 3\sin(t)-2″}  

Paul draws one playing card out of a standard poker deck and observes its value (2 though Ace) and its color (red or black).  He then replaces the card, shuffles the deck, and again draws a card, observing its value and color. Let event A =  The first card is an Ace,  and let event B = the second card is Red. Events A and B are:

A study investigates the effectiveness of a new flu vaccine.   The one-year study enlists several thousand volunteers.  40% of the volunteers are diagnosed with flu during the course of the study, and 60% are not diagnosed with flu. Of the participants who are diagnosed with flu during the study, 20% had gotten the vaccine.  Overall, 45% of participants had been assigned to the vaccine condition in the study.  What proportion of participants did not contract flu and had gotten the vaccine? Show your work.

Given the parametric equations. x=t,y=2t+1{“version”:”1.1″,”math”:”x = \sqrt{t},\, y = 2\sqrt{t}+1″} (a) Eliminate the parameter and write the corresponding rectangular equation. (b) Sketch the graph of the curve. Label at least two points on your graph. Show the orientation of the curve.  

Mary owns an antiques store.  She has calculated that each customer who enters the shop has a 22% chance of buying something. What is the probability that, of the next four customers who enter the shop, none of them buys anything?

Once you establish the extent of your fear of failure, which of the following would be a good step toward coping with it?
