1 1 of 5 he angle θ for F3 such that the re- suitant iorce is directed along the positive x- axis. If this problem is not solvable (due to un- favorable combination of variables), you must provide a physical explanation (why this can- not be solved using your individual numbers) F2 FA
3. Suppose that xi, ,xn are a random sample from a B(o, β) distribution: ere E[X H -a/(a + β) and EX2] (a + 1)a/( (a + β + 1)(a + β)) (a) Show that the method of moments, using the first two moments, gives the equations (b) Determine the method of moments estimator of α and β based on the first two moments. Note You can use the result of (a) even if you were unable to show it

6. If R is a primitive ring with identity and e ε R is such that e, e 0, then (a) eRe is a subring of R, with identity e. (b) eRe is primitive. [Hint: if R is isomorphic to a dense ring of endomorphisms of the vector space Vover a division ring D, then Ve is a D-vector space and eRe is isomorphic to a dense ring of endomorphisms of Ve.]
