Let B be a finite commutative group without an element of order 2. Show the mapping of b to b2 is an automorphism of B. However, if |B| = infinity, does it still need to be an automorphism?

Problem 2. Suppose that R is a commutative ring, and that R[X] := { (a_0, a_1, a_2, ...)^T | a_i is in R, a_i not equal to 0 for only finitely many i} is the set of polynomials over R, where we have named one particular element X := (0, 1, 0, 0, . . .)T . Show that R[X] forms a commutative ring with a suitably-chosen addition and multiplication on R[X]. This will involve specifying a “zero” element of...

Let R be a ring (not necessarily commutative), and let X denote the set of two-sided ideals of R. (i) Show that X is a poset with respect to to set-theoretic inclusion, ⊂. (ii) Show that with respect to the operations I ∩ J and I + J (candidates for meet and join; remember that I+J consists of the set of sums, {i + j} where i ∈ I and j ∈ J) respectively, X is a lattice. (iii) Give...

In this lab you will learn how to use methods from the Math class in order to calculate the area or the volume of several different shapes. If you are confused about the Methods you can access from the Math class and would like to see some examples click here. Hint: Most of these methods can be done in one line. Step 1 - circleArea In this method you will calculate the area of a circle. Before you can calculate...

For this case study we will take up the matter of genetic testing for untreatable genetic diseases. Huntington’s disease is a devastating genetic disorder with no known effective treatment. However a test for detecting the HD gene is available and relatively inexpensive to administer. Carriers of the HD gene typically develop symptoms in the prime of their life that range across a variety of physical and emotional disorders. In advanced stages they are rendered helpless against involuntary muscle spasms throughout...

Math 333 ASAP please. Suppose that X has a discrete uniform distribution f ( x ) = { 1 / 3, x = 1,2,3 0, otherwise A random sample of n = 34 is selected from this population. Find the probability that the sample mean is greater than 2.1 but less than 2.6. Express the final answer to four decimal places (e.g. 0.9876). The probability is Enter your answer in accordance to the question statement
