During a given week, the museum had attendance as shown in the table at right. a. Numerically summarize the center and spread of attendance by finding the median and interquartile range (IQR). b. The museum management needs to tell the staff members their work schedules a week in advance. The museum wants to have approximately one staff member for every 150 visitors. How many staff members should be scheduled to workeach week? Explain your reasoning. c. Why is a scatterplot not an appropriate display of this data?
$\begin{matrix} D a y & A t t e n d a n c e \\ 1 & 870 \\ 2 & 940 \\ 3 & 731 \\ 4 & 400 \\ 5 & 861 \\ 6 & 680 \\ 7 & 593 \end{matrix}$

The yield strength of CP titanium welds was measured for welds cooled at rates of $10^{\circ} C &# x 2 F; s, 15^{\circ} C &# x 2 F; s, a n d 28^{\circ} C &# x 2 F; s$ . The results are presented in the following table. (Based on the article “Advances in Oxygen Equivalence Equations for Predicting the Properties of Titanium Welds,” D. Harwig, W. Ittiwattana, and H. Castner, The Welding Journal, 2001:126s-136s.) $a m p; 71.00 a m p; 63.00 a m p; 68.65 a m p; 75.00 a m p; 68.00 a m p; 73.70 a m p; 79.67 a m p; 73.00 a m p; 78.40 a m p; 81.00 a m p; 76.00 a m p; 84.40 a m p; 75.50 a m p; 79.67 a m p; 91.20 a m p; 72.50 a m p; 81.00 a m p; 87.15 a m p; 73.50 a m p; a m p; 77.20 a m p; 78.50 a m p; a m p; 80.70 a m p; 78.50 a m p; a m p; 84.85 a m p; 88.40$
a. Construct an ANOVA table. You may give a range for the P-value. b. Can you conclude that the yield strength of CP titanium welds varies with the cooling rate?

Page Turner loves discrete mathematics. She has 8 "graph theory" books, 6 books about combinatorics, and 4 "set theory" books.
How many ways can she place her discrete mathematics books on the same shelf in a row if:
1) there are no restrictions.
2) graph theory books are next to each other but the others could be anywhere on the shelf.
3) books are organized by their topic (same kinds are next to each other).

Students pursuing advanced Math are constantly dealing with advanced Math equations that are mostly used in space engineering, programming, and construction of AI-based solutions that we can see daily as we are turning to automation that helps us to find the answers to our challenges. If it sounds overly complex with subjects like exponential growth and decay, don’t let advanced math problems frighten you because these must be approached through the lens of advanced Math questions and answers. Regardless if you are dealing with simple equations or more complex ones, just break things down into several chunks as it will help you to find the answers.
