Question

Calculate the unconfined compressive strength of a moist, fine
sand. Carefully state any assumptions you make. Illustrate your
calculations with sketches if appropriate.

Answer #1

The accompanying data is on cube compressive strength (MPa) of
concrete specimens.
112.5
97.0
92.6
86.0
102.0
99.1
95.8
103.5
89.0
86.6
(a) Is it plausible that the compressive strength for this type
of concrete is normally distributed?
The normal probability plot is not acceptably linear, suggesting
that a normal population distribution is plausible.

- Odds. Use the definition given in the text to find both the
odds for and the odds against the following events.
1.) Flipping two fair coins and getting 2 heads
- Use the definition of odds in betting to find the following
odds.

Suppose the utility function for a consumer is given by U =
5XY.
X is the amount of Good X and Y is the amount of Good Y.
a) Neatly sketch the utility function. [Ensure that you
label the graph carefully and state any assumptions that you make
in sketching the curve.]
b) Does this utility function exhibit diminishing marginal
utility? [Ensure that you explain your answer fully.]
c) Calculate the marginal rate of substitution. [Ensure that
you explain your...

Please make sure that you show all your work when solving the
problems. Feel free to make any assumptions whenever you feel
necessary. Just make sure that you clearly state your
assumptions.
Should you accept a project that costs $125,000 initially, and
provides cash flows of $45,000, $60,000 and $75,000 for the
following three years, given that the project has the same risk as
another project that requires an initial investment of $50,000 and

Question 1: Draw and
carefully describe a graph that utilizes the
Aggregate Demand/Aggregate Supply model that would illustrate the
current state of the aggregate economy in the
United States as of October 2020. The Aggregate Demand/Aggregate
Supply Model is first introduced in Chapter 11 (Links to an
external site.) of your text and is further explicated in Chapters
12 and 13. Make sure that you explain your graph in your own
words.
You should draw your own AD/AS graph which...

Make sure you state your hypotheses and rejection rule.
Calculate your test statistic and decide whether to reject the null
hypothesis or not and then explain what that conclusion means. You
will need to use formulas with proper notation and draw diagrams
for each of these problems.
3. A random sample of 115 finance majors finds that 47 work for
one of the major insurance companies. Career advisors believe fewer
than 50% of the jobs in finance come from the...

Federal income tax allows a deduction for any state tax paid
during the year. In addition, the state of Alabama allows a
deduction from its state income tax for any federal tax paid during
the year. The federal corporate income tax is equivalent to a flat
rate of 34% and the Alabama state tax rate is a flat 5%.
Both the Alabama and the federal taxable income
for a corporation is $1,000,000 before either tax is paid.
Because each tax...

Its winter time, and you areinsulating your windows with plastic
shrink wrap(although it’s a little late). You need to calculatethe
optimal spacing between the window pane and the shrink wrap to
minimize the overall heat loss fromthe house. Using your knowledge
of free convection in enclosures, calculate the optimal gap
width.Assume that the average temperature outside is 0°C, and the
inside temperature is 20°C. You can assume the window pane is the
same temp as the outside air and the...

The time to failure of an engine is modeled by a non-normal
distribution. You are assigned, as a new Engineer, to estimate the
time to failure of the ZX-300 new engine.
a) What would you try to estimate: centrality, dispersion or
proportion? Explain
b) How many samples would you advise your team to destroy in
this case in order for you to make an estimation? Explain
c) Let's say that times are hard to calculate, and you can get
only...
