A 4-year financial project is forecast to have net cash inflows of $20,000; $25,000; $30,000; and $50,000 in the next 4 years. It will cost $75,000 to implement the project, payable at the beginning of the project. If the required rate of return is 0.2, con duct a discounted cash flow calculation to determine the NPV.

A turbine blade of solution annealed INCOLOY alloy 800 is 18 in long and operates at 1400 degrees Fahrenheit. If the tip clearance is 0.2 in and centrifugal forces induce an average longitudinal stress of 10 ksi. After how many hours is expected the blade to interfere with the turbine stator due to creep?

Use the normal distribution to find a confidence interval for a
proportion p given the relevant sample results. Give the
best point estimate for p, the margin of error, and the
confidence interval. Assume the results come from a random
sample.
A 99% confidence interval for p given that p^=0.7 (this is
p hat) and n=110.
Round your answer for the point estimate to two decimal places, and
your answers for the margin of error and the confidence interval to
three decimal places.
