catter Plot, simple regression line re: the amount of tar having an effect on the amount of nicotine in cigarettes. Mainly.... the data set shows tar levels ranging from 1mg - 17mg, with an additional data point of 29..8mg - it remains on the regression line. My questions come from the 'appropriateness' questions.. My thoughts: x=0, y intercept is 0.131mg - 0 mg is below the data set so inappropriate? OR Appropriate because still plausible that a cigarette with NO tar could still have 0.131 mg of nicotine. Then...for the appropriateness of 25mg... if using the top level of the data set of 29.8mg then yes, it is appropriate as still within the parameters of the data set OR no, because 29.8mg is considered an outlier? .... I have read the book, read our notes, etc (online class) and watched videos but nothing REALLY explains what is 'appropriate or not' and the example homework from our online book, they answers were always it wasn't appropriate.

a tilebased game, 2D rectangle tiles with a size of 5000X5000 pixels per rectangle. I make every rectangle know the 4 neighbouring rectangles in the map so starting from one you can generate an essentially infinite map. I want to move this map around instead of moving the player around, the player stays centered on screen and since the map moves under him it looks like he's the one doing the moving. So I know the following things: Width and height of a single section: 5000X5000 pixels the x and y location of the center section can be a value anywhere from -5000,-5000 to 5000,5000 The visible screen real estate is 1920 X 1080 pixels big 0X,0Y always stars top left, bottom right is 5000X5000 What I need to end up with: A percentage value of howmuch this specific section is visible on screen, "inside the rectangle that is the scfeen)

or give some complimentary/bonus time while you figure it out, or figure out how to do particular things between sessions instead of during the session Current topics: understand slope and y-intercept and be able to apply it to equations written using different letters instead of m and b or instead of y and x; parallel, perpendicular line equations; calculate slope/gradient of graphs/sides of shapes/equations; calculate midpoint; calculate distance between two points on a graph; find the equation of a line given a graph or given 2 points; learn the meanings of symbols such as R for real numbers, Z for integers' calculate area of a triangle on a graph The student is in Kazakhstan and speaks Russian and Kazakh fluently, but is intermediate in English. Please speak with her in English as much as possible, but knowing Russian or Kazakh would be a good bonus that would make you preferable to other tutors all else being about the same, though familiarity with TI calculators or the ability to figure them out is also very important.

et loans (he doesn't "earn" income). With the loans (L) he needs to decide between first period consumption (C1) and investment (I). The amount invested will allow him to get a second period income Y with probability P which is increasing in I (therefore, P(I)), In case of success and the person obtain Y, the individual should use Y to repay the loan (L) that he requested in the first period and consume in the second period (C2). However, with probability 1 - P(I), the person don't get Y and therefore only consume C1. Note that if the individual only invest the loan (L=I) and don't obtain Y, he can't consume anything. That motivates him not to invest the whole loan and keep part of the loan in order to warrant at least first period consumption. Therefore, considering B the parameter for the time preference, the problem would be: max U=ln(C1) + Bln(C2) s.t: L = I + C1 Y(I) = L(1+r) + C2 with Probability P(I) or s.t: L = I + C1 with probability 1 - P(I) My question is, Have you ever seen something like this? If yes, how to proceed? What is more important, I really need a bibliography (a book or article talking about this)

Attachment theory hypothesizes that children's relationships with their parents shape habitual patterns of attachment in close relations. Thus, ones childhood experiences should connect to relationship quality during adulthood. Many years ago, a large group of teenage boys had been interviewed about their families. These interviews were coded to provide data in childhood family environment- a measure on which low numbers reflected distant/punitive/cold relationships with parents while higher numbers reflected nurturing/autonomous/warm relationships. Many decades later, researchers attempted to re-contact these same people. A total of 81 men(aged 70-85 years) who had been married to the same spouse for at least ten years and agreed to participate were interviewed about their marriage. The spouses of these men were interviewed as well. The interviews were coded in order to provide a measure of relationship attachment-higher scores reflected greater levels of relationship satisfaction,loving, and caring. Is there any evidence to support attachment theory's claim that children's parental relationships predict relationship quality in adulthood?
