A manufacturing company wants to develop control charts to measure the quality of its steel plate. They take ten sheets of 1" steel plate and compute the number of cosmetic flaws on each roll. Each sheet is 20' by 100'. Based on the following data.

a. Compute the lower control (LCL) limit

b. Compute the upper control (UCL) limit

c. Is the process under control ?

Determine if exact equation, then solve:

x(y+2)y' = lnx+1 , y(1) = -1

Figure 1. Water at 1 K Figure 2. Argon at 1 K Figure 3. Oxygen at 1 K Figure 4. Neon at 1 K a) As demonstrated in the above figures, explain in detail why water, H2O, expands upon freezing whereas the other substances in these figures contract upon freezing. In your answer ensure that you address the bonding, polarity, density and other relevant factors to describe these phenomena. b) Draw the structure of water when it freezes. c) Link the phenomena indicated from this observation to explain important aspects of the existence of life on our planet Earth. d) Are there any other substances which exhibit similar behaviour? If so, identify these substances by name, chemical symbol/formula, and a brief description – if there are many such substances, identify at least three of these substances.

You returned to Aguamaint about mid-afternoon on Wednesday, January 7. Jerry Loos had prepared written responses to all of your questions. After getting clarification on a couple of points, you are ready to get to work to complete the necessary adjusting and correcting entries.

REQUIRED:

Use the information provided below to create all adjusting and correcting journal entries needed to assure that Aguamaint’s financial statements will be in accordance with U.S. GAAP. Documentation for each journal entry should include a detailed explanation and all necessary calculations.

The issues:

1. Are all receivables collectible? Do you require an allowance for doubtful accounts?

Collection of the receivables will be no problem. We know all the customers with whom we have a contract and we have reviewed each of the accounts at year-end for any potential problems. Everyone has paid on time thus far.

Write 1 to 1 and 1/2 pages (single space) paper. Describe how ETFs are same, and how they are different than mutual funds. And what role ETFs can play in investment strategy.

1. Determine the ROC for stability for transfer function H(s) = 1 / (s-2) ( s-1)

2. Determine the ROC for stability for transfer function H(z) = (z-1) / (z+0.1) (z-0.2)

SO3(g) can be produced by this two step process:

1.) 2FeS2 + 1 1/2 O2 = Fe2O3 + 4SO2

2.) SO2 + 1/2 O2 = So3

How many grams of SO3 can be produced from the reaction of 45.0 g of FeS2 if there is no experimental error? How many grams would actually be measured if reaction 1 had 100% yield and reaction 2 had 83.4% yield?

x: 1.5, 1, .25, .5

y: 3.75, 2, 1, 1.75

1) what is the % variation in y explained by the regression

2) test the null hypothesis that the slope =0 with the alternative that slope is not =0 and using alpha =.01. write down the test p value and state your conclusion about the hypothesis.

Prove by induction that:

1) x^n - 1 is divisible by x-1

2)2n < 3^n for all natural numbers n
