A rectangular storage container with an open top is to have a volume of 18 cubic meters. The length of its base is twice the width 𝑥. Material for the base costs 11 dollars per square meter. Material for the sides costs 6 dollars per square meter. Answer the following: (a) Determine the cost function 𝐶(𝑥), where 𝑥 denotes the width of the box. Do not include the dollar sign in your answer. 𝐶(𝑥) = (b) Find the cost for the cheapest such container. Total cost =

Carbon monoxide: A recent study examined the effects of carbon monoxide exposure on a group of construction workers. The following table presents the numbers of workers who reported various symptoms, along with the shift (morning, evening, or night) that they worked. Influenza Headache Weakness Shortness of Breath Morning Shift Evening Shift Night Shift 19 10 10 33 22 8 16 11 8 10 9 11 Send data to Excel Test the hypothesis of independence. Can you conclude that symptoms and shift are not independent? Use the $\alpha = 0.01$ level of significance and the $P$-value method with the TI-84 Plus calculator. Part 1 of 7 (a) State the null and alternate hypotheses. $H_0$: The shift and reported symptoms are $\blacktriangledown$Independent. $H_1$: The shift and reported symptoms are not $\blacktriangledown$Independent. Part 2 of 7 (b) Compute the value of the chi-square statistic. Round the answer to three decimal places. $\chi^2 = 7.922$ Part 3 of 7 (c) How many degrees of freedom are there? Degrees of freedom = 6 Part 4 of 7 (d) Find the $P$-value. Round the answer to four decimal places. The $P$-value is 0.2439 Part: 4 / 7 Part 5 of 7 (e) Compute the expected frequencies. Round the answer to three decimal places. Influenza Headache Weakness Shortness of Breath Morning Shift Evening Shift Night Shift

You need to create the Graphical User Interface version of programming assignment 1. Use tkinter to produce a form that look much like the following. It doesn't need to look exactly like this (and probably it can't, but it should be similar). It should have these widgets in any case. It should probably have the entry elements at the top of the form, the radio buttons kind of in the middle, the Convert and Clear buttons next, then the output stuff. However, you may arrange, layout, align the widgets in any manner you think is reasonable as long as the form would make sense for someone to use. Temperature Converter Enter a temperature Convert to Fahrenheit Convert to Celsius Convert Value Clear Result The user will enter a temperature in the first entry box. They will then click either the Convert to Fahrenheit or the Convert to Celsius radio button (but not both). And when they click the Convert button the value entered in the first entry box will be converted to the proper temperature and put into the second entry box. For full credit you need: \begin{itemize} \item use a class that inherits Frame to implement your program. \item Your 2 entry boxes need to have labels explaining the purpose of the entry boxes. \item Round the result to 1 decimal place. \item In addition to the Convert Value button, you need to have a Clear button that clears both entry boxes. \end{itemize}

Let U (X; Y) = \sqrt{XY} represent the benefit that a consumer will obtain from the goods X and Y. Let Px, Py denote the prices of the goods and M is the income of the consumer. 1. Calculate the marginal utility of goods X and Y. 2. Show uncompensated (Marshallian) claims for X and Y goods using the lagrange method. 3. Let it be given as M = 100, Px = 20 and Py = 25. In this case, by calculating the optimal consumption of the consumer; at this point Show that the equation marginal principle applies. 4. Using the Slutsky equation, calculate numerically after determining the substitution effect of X when its price changes.
