Determine whether the statement is true or false. If it is false, rewrite it as a true statement. Using a systematic sample guarantees that members of each group within a population will be sampled. Choose the correct answer below. A. False. Using a cluster sample guarantees that members of each group within a population will be sampled. B. False. Using a stratified sample guarantees that members of each group within a population will be sampled C. True.

The temperature of a person during a certain illness is given by the following equation, where \( T \) is the temperature \( \left({ }^{\circ} \mathrm{F}\right) \) at time \( t \), in days. Find the relative extreme points and sketch a graph of the function. \( T(t)=-03 t^{2}+24 t+983,0 \leq t \leq 8 \)

11)Paci a ecuacoos a) \( y=5 x+2 \) b) \( y=-3 x-13 \) d) \( y=-\frac{2}{3} x+\frac{1}{3} \)

g) \( \frac{x}{7}+\frac{4}{7}+\frac{x}{2}-\frac{1}{2}+4=7 \)

Write the radical as a pure imaginary number. \( \sqrt{-343} \) \( \sqrt{-343}=\square \) (Simplify your answer. Type an exact answer, using radicals as needed. Express
