Consider the following scatter plots of realizations (samples) of (X, Y ) sampled from five different joint Gaussian distributions: a) Rank the values of Cov(X, Y ) for a-e. Explain your ranking. b) Would you expect that X and Y for any of these graphs would be statistically independent

Find the exact value of each of the following. in each case, show your work and explain the steps you take to find the value. (a) sin 17π/6 (b) tan 13π/4 (c) sec 11π/3

Which function has the domain x> -11?

Will mark determine whether the conjecture is true or false. give a counterexample for any false conjecture. given: points r, s, and t conjecture: r, s, and t are coplanar. a) false; the points do not have to be in a straight line. b) true c) false; the points to not have to form right angles. d) false; one point may not be between the other two.
