What do you think is the author's perspective on publishing his first story as a boy?

Draw the pie charts for the frequency distributions. Use a pie chart to show the percentage of Americans with the indicated blood type. $$ \begin{matrix} \text{Blood Type} & \text{\\% with This Type}\\ \text{0} & \text{43}\\ \text{A} & \text{40}\\ \text{B} & \text{12}\\ \text{AB} & \text{5}\\ \end{matrix} $$

For a data set with a first quartile of Q1 and a third quartile of Q3, a value less than Q1-1.5(IQR) or greater than Q3+1.5(IQR) may be considered to be an outlier. Use this rule to identify any outliers in each data set. Show your work. {2,3,4,5,5,25}

The adsorption of solutes on solids from liquids often follows a Freundich isotherm. Check the applicability of this isotherm to the following data for the adsorption of ethanoic acid on charcoal at $25^{\circ} \mathrm{C}$ and find the values of the parameters $c_{1}$ and $c_{2}.$

$$\begin{matrix} \text{$[\mathrm{acid}] /\left(\mathrm{mol}\ \mathrm{dm}^{-2}\right)$} & \text{0.05} & \text{0.10} & \text{0.50} & \text{1.0} & \text{1.5}\\ \text{$\mathrm{w}^{1} _{4} / \mathrm{g}$} & \text{0.04} & \text{0.06} & \text{0.12} & \text{0.16} & \text{0.19}\\ \end{matrix}$$

where $\mathrm{w}_{4}$ is the mass adsorbed per gram of charcoal.

A person walks 1 km, turns around, and runs back to where he started. Compare the energy used and the power during the two segments. A. The energy used and the power are the same for both. B. The energy used while walking is greater, the power while running is greater. C. The energy used while running is greater, the power while running is greater. D. The energy used is the same for both segments, the power while running is greater.

For matrix

, compute its eigenvalues, eigenvectors and the dimension of eigenspace.

Use a calculator to find the approximate value of each expression rounded to two decimal places. sin 1

Find the inverse of each one-to-one function. State the domain and the range of each inverse function.

Find the GCF of each pair of numbers.

$$45 \ \text{and} \ 81$$

Let

$$\mathbf{u}=\left[ \begin{array}{l}{3} \\ {0}\end{array}\right]$$

and

$$\mathbf{v}=\left[ \begin{array}{l}{1} \\ {2}\end{array}\right]$$

. Compute the area of the parallelogram determined by u, v, u+v, and 0, and compute the determinant of [u v]. How do they compare? Replace the first entry of v by an arbitrary number x, and repeat the problem. Draw a picture and explain what you find.

Perform the indicated operation by first expressing each number in scientific notation. Write the answer in scientific notation. $\frac{0.0018}{0.0000006}$

Find the intercepts and asymptotes, and then sketch a graph of the rational function and state the domain and range. Use a graphing device to confirm your answer.

$$r ( x ) = \frac { 3 x ^ { 2 } + 6 } { x ^ { 2 } - 2 x - 3 }$$

Simplify the expression. Assume that all variables are positive.

$$\sqrt [ 4 ] { \frac { 32 } { x ^ { 4 } } }$$

Simplify the expression.

$$\sqrt { 5 } ( 2 \sqrt { 6 x } - \sqrt { 96 x } )$$
