Statistics : Predictor or Explanatory Variable and Strength of Relationship
1. In graphing the relationship between two variables, the predictor (also called explanatory) variable is found on the x / y (choose one) axis. (you might have to think about his one!) 2. You are reading an article that reported the results of a study that examined the relationship between duration of television watching f ...continues

8 Topology Questions : Hausdorff Space, Countability, Compactness and Homomorphisms
1. Show that the collection
13 {[O,c)J 0
Using the fact that 1+x = 4+(x-3), find the Taylor series about 3 for g. Give explicitly the numbers of terms. When g(x)=square root of 1+x Check the first four terms in the Taylor series above and use these to find cubic Taylor polynomials about 3 for g. Use multiplication of Taylor series to find the quartic Taylor polyn ...continues
