HOMEWORK EXAM 1 CHEM 142 QUESTIONS AND ANSWERS GRADED A Is there an attraction between two neutral helium atoms? Explain in detail why or why not. Be sure to include any evidence you have for your claim and how this supports your reasoning. Yes; 2 helium atoms can be attracted because the electrons in the electron cloud are freely moving. This leads to one of the atoms becoming an instantaneous dipole, this will then induce a dipole on the other atom. The opposite partial charges will a...

MAT 133 (MATH) 4-3 Homework Questions with Solutions 2023. The probability that a student has a Visa card (event V) is .60. The probability that a student has a MasterCard (event M) is .20. The probability that a student has both cards is .12. (a) Find the probability that a student has either a Visa card or a MasterCard. Formula for "OR" Probability : P(A U B) = P(A) + P(B) – P(A ∩ B) P(Visa or Mastercard) = P(Visa) + P(Mastercard) – P(Visa and Mastercard): .60 + .20 - .12 = .68...

MAT 133 5-3 Homework Assignment Solutions (MAT 133-J4254) Oxnard Petro Ltd. is buying hurricane insurance for its off-coast oil drilling platform. During the next five years, the probability of total loss of only the above-water superstructure ($250 million) is .30, the probability of total loss of the facility ($950 million) is .30, and the probability of no loss is .40. Find the expected loss. Expected loss is the same as the mean. We have 3 different x-values here because we have 3 diff...

4-3 Homework Help MAT 133-J4254 | Questions with Solutions. Suppose the probability of an IRS audit is 1.4 percent for U.S. taxpayers who file form 1040 and who earned $100,000 or more. (a) What are the odds that such a taxpayer will be audited? P(A) = P(the taxpayer will be audited): 1.4% → .014 P(A’) = P(the taxpayer won’t be audited) = 1 - .014 = .986 b) What are the odds against such a taxpayer being audited? Here is a video you can watch for Problem 2: Homework Problem 3 Reca...
