Compare the dot plots by answering the questions.

How do the modes compare?

Answer these questions for each of the given functions. i. Is $f$ one-to-one? Justify your answer. ii. Is $f$ onto? Justify your answer.iii. Is $f$ bijective? If yes, find $f^{-1}$.(b) $f: \mathrm{Q} \rightarrow \mathrm{Q}$ is defined by $f(a)=\frac{5-2 a}{3}$.

Choose the best answer.Right triangle FGH has midsegments of length 10 centimeters, 24 centimeters and 26 centimeters. What is the area of ΔF:,G. H? A 60cm², B 120cm², C 240cm², D 480 cm².

For this exercise, refer to the pictograph in the earlier example.

Write a question that could be answered using the pictograph. Have a classmate answer your question.

When asked to factor

$$81 t ^ { 2 } - 16$$

, one student answered (9t - 4)(9t + 4), and another answered (9t + 4)(9t - 4). Explain why both students are correct.

Why should objections be answered promptly?

Answer these questions for each of the given functions. i. Is $f$ one-to-one? Justify your answer. ii. Is $f$ onto? Justify your answer.iii. Is $f$ bijective? If yes, find $f^{-1}$.(a) $f: 2 Z \rightarrow Z$ is defined by $f(a)=\frac{3 a-4}{2}$.

How does the cost of a movie depend on its length? Data on the cost (millions of dollars) and the running time (minutes) for major release films of 2005 are summarized in these plots and computer output:$\newline$

$$\newline$$

Dependent variable is : Budget($M)$<br>$R-squared$= 15.4\% <br> s = 32.95$with$120- 2 = 118$degrees of freedom$

$$\begin{alignat*}{7} \textbf{Variable} \quad &\textbf{Coefficient} \quad &\textbf{SE(Coeff)} \quad &\textbf{t-Rate} \quad &\textbf{P-Value} \\ \text{Intercept} \quad & -31.3869\quad & 17.12\quad & -1.83\quad & 0.0693\\ \text{Run Time} \quad & 0.714400\quad & 0.1541\quad & 4.64\quad & \le0.0001 \end{alignat*}$$

$ Explain what that means in this context.

$ Explain in context what the regression says.

Suppose the cost function of manufacturing cost for a certain product be approximated by

$$C(x, y)=3 x^2+y^2-x-y-3 x y+100,$$

where $x$ is the cost of labor per hour and $y$ is the cost of materials per unit. Find values of $x$ and $y$ that minimize the cost function. Find the minimum cost.

Is a high contribution margin ratio good?
