The molarity of a solute in solution is defined to be the number of moles of solute per liter of solution (1 mole = 6.02 × 1023 molecules). If X is the molarity of a solution of magnesium chloride (MgCl2), and Y is the molarity of a solution of ferric chloride (FeCl3), the molarity of chloride ion (Cl−) in a solution made of equal parts of the solutions of MgCl2 and FeCl3 is given by M = X + 1.5Y . Assume that X has mean 0.125 and standard deviation 0.05, and that Y has mean 0.350 and standard deviation 0.10.
a. Find the mean of M
b. Find the standard deviation of M (assume X and Y are independent).
Please help, need accurate solutions

Use the converse of the side-splitter theorem to determine if tu || rs. which statement is true? line segment tu is parallel to line segment rs because 32/36 = 40/50 line segment tu is not parallel to line segment rs because 32/36 not equal 40/50. line segment tu is parallel to line segment rs because 32/36 = 40/50. line segment tu is not parallel to line segment rs because 32/36 not equal 40/50 .
