Discuss the following conservation laws: energy, linear momentum, angular momentum, electric charge, baryon number, lepton number, and strangeness. Are all of these laws based on fundamental properties of nature? Explain.

How did the split of the Democratic Party affect the outcome of the 1860 election and the Southern states'decision to secede?

Why did Andrew Jackson defeat John Quincy Adams so dramatically in the $1828$ election?

Test the following decays for violation of the conservation of energy, electric charge, baryon number, and lepton number. $\mu^{-} \rightarrow \mathrm{e}^{-}+\bar{v}_e+v_{\mu^{-}}$ Assume that linear momentum and angular momentum are conserved. State which conservation laws (if any) are violated in each decay.

Identify and explain the effect on Czechoslovakia of the reforms Alexander Dubcek introduced after his election in 1968.

You and your best friend are among several candidates running for class president. You estimate that there is a $40 \%$ chance you will win the election and a $35 \%$ chance your best friend will win. What is the probability that either you or your best friend wins the election?

Why do you think Americans voted so overwhelmingly for Johnson in the presidential election of 1964?

Determine whether the data are discrete or continuous.

14. Votes received by mayoral candidates in a city election

Give one reason why most southerners were upset about Lincoln's election in 1860.

Voting patterns. A survey of a precinct’s residents revealed that $55\%$ of the residents were members of the Democratic party and $60\%$ of the Democratic party members voted in the last election. What is the probability that a person selected at random from this precinct is a member of the Democratic party and voted in the last election?

Why did Andrew Jackson defeat John Quincy Adams so dramatically in the $1828$ election ?

Use the Laws of Logarithms to expand the quantity. $\ln \sqrt{a b}$

Use scientific notation, the Laws of Exponents, and a calculator to perform the indicated operations. State your answer rounded to the number of significant digits indicated by the given data.

$$\frac{\left(3.542 \times 10^{-6}\right)^9}{\left(5.05 \times 10^4\right)^{12}}$$

In an election held last year that was contested by three parties. Party A captured 31% of the vote, party B garnered 51%, and party C received the remaining votes. A survey of 1,200 voters asked each to identify the party that they would vote for in the next election. These results were recorded where 1 = party A, 2 = party B, and 3 = party C. Can we infer at the 10% significance level that voter support has changed since the election?
