Use logarithmic notation to represent the solution to each of the following equations. If there is no solution, enter "DNE".
Professor Lapan's Helpful Hint: For this question, do not evaluate solutions numerically. Instead, choose logarithms that undo the given exponential function. For example, $f(x)=9^{x}$ has inverse function $g(x)=\log _{9}(x)$ , so to solve an equation like $9^{x}=10$ , use $\log _{9}(x)$ in this question. This question emphasizes that $b^{x}$ and $\log _{b}(x)$ are inverses. a. $7^{x}=59$ $x=$ $\square$ b. $7^{x}=\frac{1}{2401}$ $x=$ \begin{tabular}{lll} -4 & X \\ \hline \end{tabular} c. $4^{x}=-75$ $x=$ DNE

In randomized, double-blind clinical trials of a new vaccine, rats were randomly divided into two groups. Subjects in group 1 received the new vaccine while subjects in group 2 received a control vaccine. After the second dose, 113 of 748 subjects in the experimental group (group 1) experienced fever as a side effect. After the second dose, 70 of 629 of the subjects in the control group (group 2) experienced fever as a side effect. Does the evidence suggest that a higher proportion of subjects in group 1 experienced fever as a side effect than subjects in group 2 at the $\alpha=0.10$ level of significance? C. The samples are independent. D. The samples are dependent. E. The sample size is less than $5 \%$ of the population size for each sample. F. The data come from a population that is normally distributed.

Problem 14196

POSSIBLE POINTS
A diagram demonstrates the Pythagorean Theorem, which states that for a right triangle with legs $a$ and $b$ and hypotenuse $c, a^{2}+b^{2}=c^{2}$ .
How are the squares in the diagram related to the equation? The number of unit squares in each square is equal to the adjacent side length. The square of the sum of the legs equals the square of the hypotenuse. The square shapes represent the squares of the side lengths, and the sum of the areas of the two smaller squares equals the area of the larger square. The squares represent the side lengths of the triangle. The sum of the side lengths of the legs equals the length of the hypotenuse. The square of the sum of the lengths of the sides of the triangle equals the number of unit squares in all the squares.
