Solve the equation and check your solution.

Look at each function. Is the point (-2,-1) on the graph of the function? Select Yes or No

$$h(x) = - \frac{1}{2}|x|$$

Let $W$ be the amount of water, in gallons, in a bathtub at time $t$, in minutes.

What are the meaning and units of $dW/dt$?

Suppose that 30% of a certain radioactive substance decays in 5 years. Suppose that a certain quantity of this substance is stored in a cave. What percentage of it will remain after t years?

Measuring the height of a California redwood tree is very difficult because these trees grow to heights over 300 feet. People familiar with these trees understand that the height of a California redwood tree is related to other characteristics of the tree, including the diameter of the tree at the breast height of a person (in inches) and the thickness of the bark of the tree (in inches). The file Redwood contains the height, diameter at breast height of a person, and bark thickness for a sample of 21 California redwood trees. At the $0.05$ level of significance, determine whether each independent variable makes a significant contribution to the regression model. Indicate the independent variables to include in this model.

Prove that $A \subseteq(A \cup B)$ where A and B are arbitrary sets.

Mammogram Report:

Exam: Diagnostic bilateral mammogram

Reason for exam: Discomfort in both breasts

The glandular tissue is heterogeneously dense. There are scattered fibroglandular densities bilaterally. There is a benignappearing curvilinear area of glandular tissue in the right lower inner breast. There are a few faint calcifications in the lower inner left breast and in the central left breast. Magnification views were performed of the left breast calcifications in two positions, and they have an appearance most consistent with benign process. There is no associated mass or distortion. Impression: Heterogeneously dense glandular tissue with focal glandular density in the medial aspect of the right breast and faint calcifications in the left breast. Probably benign.

Recommendation: Comparison with prior films. If prior films are not available, recommend follow-up mammogram in 6 months. Findings were submitted to the patient in writing.

Answer the question about the report by filling in the blanks.

Define $bilateral$.

$$\rule{10cm}{0.15mm}$$

$$\rule{10cm}{0.15mm}$$

Describe the relationship between physical activity, weight, and health.

Consider the function $f(x) =\dfrac{3}{2}x^{2}$. Dan says that the graph of this function will look more compressed than the graph of $f(x) = x^{2}$ because the $A-$value is a fraction. Jeannie says that the graph of this function will look more stretched because the $A-$value is greater than 1 Who is correct? Explain your reasoning.

Construct a frequency distribution and a frequency polygon for the data set. Describe any patterns.

Data set: Number of children of the U.S. presidents

$$\begin{array}{rrrrrrrrrrrrrr}0 & 5 & 6 & 0 & 3 & 4 & 0 & 4 & 10 & 15 & 0 & 6 & 2 & 3 \\ 0 & 4 & 5 & 4 & 8 & 7 & 3 & 5 & 3 & 2 & 6 & 3 & 3 & 1 \\ 2 & 2 & 6 & 1 & 2 & 3 & 2 & 2 & 4 & 4 & 4 & 6 & 1 & 2\end{array}$$

People familiar with these trees understand that the height of a California redwood tree is related to other characteristics of the tree, including the diameter of the tree at the breast height of a person (in inches) and the thickness of the bark of the tree (in inches). The file Redwood contains the height, diameter at breast height of a person, and bark thickness for a sample of 21 California redwood trees. Construct a 95% confidence interval estimate of the mean height for trees that have a breast-height diameter of 25 inches and a bark thickness of 2 inches, along with a prediction interval for an individual tree.
