Identify the variables and classify them in terms of level of measurement, and whether they are discreet or continuous. Is each variable dependent or independent? Does tolerance for diversity vary by race or ethnicity? Samples of white, black, Asian, Hispanic, and Native Americans have been given a survey that measures their interest in and appreciation of cultures other than their own (respondents answer a set of questions and rank their responses as never, rarely, sometimes, often, and always).

Boyle's Law explores the effects of pressure on the volume of an ideal gas. Boyle observed the change in pressure and volume relationship in a gas. The pressure of a gas in a closed container is __________ to the volume of the gas in the container (assuming constant temperature).

Definition 3 (IVP-ext). A function $f$ on $[a, b]$ satisfies the IVP-ext condition if, for every subinterval $[a_1, b_1] \subseteq [a, b]$ and for each $y$ between $f(a_1)$ and $f(b_1)$, the set $S_y$ defined by $S_y = \{x \in [a_1, b_1] | f(x) = y\}$ is a closed nonempty set.

WHY STUDY The Structure of Crystalline Solids? The properties of some materials are directly related to their crystal structures. For example, pure and un- deformed magnesium and beryllium, having one crys tal structure, are much more brittle (i.e., fracture at lower degrees of deformation) than are pure and un- deformed metals such as gold and silver that have yet another crystal structure (see Section 7.4). Furthermore, significant property differences exist between crystalline and noncrystalline materials having the same composition. For example, noncrys- talline ceramics and polymers normally are optically transparent; the same materials in crystalline (or semi- crystalline) form tend to be opaque or, at best, translucent.
