Consider a cipher that has three keys, three plaintexts, and four ciphertexts that are combined… Consider a cipher that has three keys, three plaintexts, and four ciphertexts that are combined using the following encryption table (table 2): Suppose further that the plaintexts and keys are used with the following probabilities: f(m1) = f(m2) = 2 […]
circles find the equation of the circle through the point of intersection of circles x2+y2-4x-6y-12=0 and x2+y2+6x+4y-12=0 and cutting the circle x2+y2-2x-4=0 orthogonally.
Suppose that the key equivocation of a certain cryptosystem vanishes, i.e H(K|C) = 0. Prove that… Suppose that the key equivocation of a certain cryptosystem vanishes, i.e H(K|C) = 0. Prove that even a single ciphertext uniquely determines the key. (d) Show that the unicity distance of the Hill Cipher over Z26 (with an m […]

Please only two attempts are left and i have 1 hour left The U.S. Food and Drug Administration lists dichloromethane (CH2Cl2) and carbon tetrachloride (CCl4) among the many chlorinated organic compounds that are carcinogenic (cancer-causing). What are the partial pressures of these substances in the vapor above a solution of 1.13 mol of CH2Cl2 and […]
heat and energy The oxidation of copper 1 oxide, Cu2O (s) to copper 2 oxide, CuO (s) is an exothermic process: 2Cu2O (s) + O2 (g) -> 4CuO (s) deltaH= -292.0 kJ x mol-1 Calculate the energy released as heat when 25.0 grams of Cu2O (s) undergo oxidation at constant pressure.
chemical formula What is the chemical formula for: 75.69% C, 8.80% H, and 15.51% O and has a molar mass of 206 g/mol
Lewis formulas Consider the hypothetical elements X, Y, and Z with the following Lewis formulas. X with seven electron dots around it, Y with six electron dots, and Z with five electron dots. To which groups in the periodic table would each element belong?
psychologist studied three computer keyboard designs psychologist studied three computer keyboard designs. Three samples of individuals were given material to type on an particular keyboard and the number of errors committed by each subject was recorded. The data are as follows: keyboard A: 0,4,0,1,0 keyboard B: 6,8,5,4,2 Keyboard C: 6,5,9,4,6 Does typing performance differ significantly […]
