When designing a new warehouse, its size is the most critical attribute. This is because once built, the outer walls of the warehouse form the boundaries within which all operations must take place.

Propose a solution in a essay form with explanations and examples, on how the cubic storage capacity of a warehouse can be increased given a fixed warehouse floor area. (warehouse management)

In forming a chelate with a metal ion, a mixture of free EDTA (abbreviated Y4−) and metal chelate (abbreviated MYn−4) can buffer the free metal ion concentration at values near the dissociation constant of the metal chelate, just as a weak acid and a salt can buffer the hydrogen ion concentration at values near the acid dissociation constant.

The equilibrium

Mn++Y4−−⇀↽−MYn−4

is governed by the equation

K′f=αY4−*Kf=[MYn−4]/[Mn+][EDTA]

here Kf is the association constant of the metal and Y4−, αY4− is the fraction of EDTA in the form Y4−, and [EDTA] is the total concentration of free (unbound) EDTA. K′f is the conditional formation constant.

How many grams of Na2EDTA⋅2H2O (FM 372.23 g/mol) should be added to 1.55 g of Sr(NO3)2⋅4H2O (FM 283.69 g/mol) in a 500. mL volumetric flask to give a buffer with pSr2+=8.00 at pH 10.00? logKf for Sr−EDTA is 8.72 and αY4− at pH 10.00 is 0.30.

The epidemiology lab at the UVA Hospital is trying to estimate how COVID-19 is affecting African American communities living near the Hospital. They know that the infection rates of African Americans in the Baltimore area have been high, at 12% since March 2020. A small team of courageous researchers samples 12 people on the street in several areas near the Hospital – to ensure that they don’t know each other.

a. Please write out the values of the random variable X (the number of people who could be infected in the sample) and its probability distribution. Also draw a histogram of this probability distribution. Then, compute the mean using both the definitional formula and the special formula for this probability distribution.

b. What is the standard deviation of this sample? Compute this standard deviation using both the definitional formula and the special formula for this probability distribution.

c. What is the probability that exactly one-third of this sample is infected with COVID-19?

d. What is the probability that less than 3 students in this sample are infected with the virus?

e. If a much larger group of 110

A real estate investor wants to study the relationship between annual return on his commer- cial retail shops (measured in thousands of dollars) as it relates to their location and the number of homes near the shops. Specifically, the investor has collected data on the annual return of the shops, the number of households within 15 miles of the shops (measured in thousands), and the location of the shops (whether the shops are in a suburban area, near a shopping mall, or downtown). The annual return data can be found in the file “RealEstate.csv” in the d2l. As demonstrated in the lecture, please create a subset data of size 18 and perform your statistical analysis for the subset data. Please note that the subset data should be a random sample of the given data.

(a) State the mean of the response.
(b) Is the multiple linear regression model useful for prediction? Show details. Use ? = 0.05. (c) Provide the detailed interpretations of b1, b2, and b3 in the context of the problem.

(d) Use your estimated regression equation to predict the annual return for a shop in mall with 120,000 households near the shop.

Shop. Annual Return($1000s). Number of Households(1000s). Location.

Real GDP (Y) can be decomposed into the sum of spending by consumers (C), firms (I), the government (G), and net exports (X-M). Y = C + I + G + NX. A common approach taken in exploring real GDP developments is to explore how each of these four spending components identified will develop in the near future. For example, if consumer confidence (an example of a forward-looking indicator) is increasing, this is usually taken as a signal that C will be increasing at a 'healthy' growth rate in the near future. If consumer confidence is decreasing, then C is expected to be flat. Since the spending components feed into real GDP (go back to the circular flow diagram), the development of C gives some indication about near-future developments in real GDP or economic growth. Thus, one can explore expected changes in C, I, G, and NX to get a handle on the expected real GDP growth for the next quarter or year. Your assignment is to develop a report that describes expectations for US RGDP in the short term (6 months to 1 year) and medium-term (2 to 3 years). This type of macroeconomic outlook report is important and of interest to every type of business enterprise as it is the basic indicator of future output and input market conditions. Your report should be addressed to someone who has only a basic understanding of economics; thus, you should as part of your report, explain the definition of each of the spending components (any other technical terms you use). You may use charts and graphs as appropriate. The finished report should be 3 to 5 pages and include an Executive Summary of no more than 200 words.
