Foreign Language Speaking Dorms: A local college recently made the news by offering foreign language-speaking dorm rooms to its students. When questioned at another school, 50 randomly selected students from each class responded as shown. At α = 0.01, is there sufficient evidence to conclude that the proportions of students favoring foreign language-speaking dorms are not the same for each class? Yes - 12, 14, 19, 24. No - 38, 36, 31, 26. Identify hypothesis and claim? Find the critical value? Find the χ² value? Reject the claim or not?

Which of the following statements a), b) or c) is false? If before a function returns it makes a call to another function, the interpreter pushes a stack frame for that function call onto the stack. Thus, the return address required by the newly called function to return to its caller is now on top of the stack. The top stack frame always contains the information the currently executing function needs to return control to its caller. For each function call, the interpreter pushes a stack frame onto the stack. This entry contains the return location that the called function needs so it can return control to its caller. When the function finishes executing, the interpreter pops the function's stack frame, and control transfers to the return location that was popped. All of the above statements are true.

Verify the identity algebraically. Use the table feature of a graphing utility to check your result numerically. (Simplify at each step.) \frac{5}{\cos(x)+1} + \frac{5}{\cos(x)-1} = -10 \csc(x) \cot(x) \frac{5}{\cos(x)+1} + \frac{5}{\cos(x)-1} = \frac{\boxed{}-5+5\cos(x)+5}{(\cos(x)+1)(\cos(x)-1)} = \frac{\boxed{}}{\cos^2(x)-1} = \frac{\boxed{}}{-\sin^2(x)} = -10 \frac{\boxed{}}{\sin(x)} \cdot \frac{\cos(x)}{\sin(x)} = -10 \csc(x) \cot(x)
