A first-order pressure sensor must meet the following dynamic response specifications: (a) At least 95% accuracy within 0.09s after a step input. (b)The delay corresponding to a ramp input of 60 psi/s is less than 0.02s. (c) Steady-state error of no more than 1 psi for a ramp input of 100 psi/s. (The dynamic error for an input ramp corresponds to the following definition: (d) The dynamic error is to be held smaller than 10% for measuring a turbulent flow with fluctuations of up to 30 Hz. Find a transfer function which has the largest allowable time constant for this sensor.

A box contains 100 Christmas light bulbs -- 40 green, 35 red and 25 blue. You randomly select two bulbs from the box with replacement. The outcome of interest is the colour of each of the two selected light bulbs. (a) List the complete sample space of outcomes. (1 mark) (b) What is the probability that the two selected bulbs are the same colour? (1 mark) (c) What is the probability that the first selected bulb is green or that the second selected bulb is red? (1 mark) Instead of typing the intersection symbol ∩, you can type "and". Instead of typing the union symbol ∪, you can type "or".

The following information is for a collateralized mortgage obligation (CMO). Tranche A of $50 million receives quarterly payments at 9 percent per year, tranche B of $100 million receives quarterly payments at 10 percent per year, and tranche C of $50 million receives quarterly payments at 11 percent per year.
5. What is the principal outstanding on Tranche A, Tranche B, and Tranche C after the end of year payment in the previous question? (0.2 points)

Another topic that no one seems to consider is driving a 4x4 truck across the surface of Mars, years of experimenting with a robot vehicle when you have 100 years of progress with the motorcar.
So you have a fuel laden Chevy Silverado with air tanks for the fuel/air mixture and you set it on a course to drive a long distance photographing the terrain as it goes, even deploy a drill that is powered by the enging. The result is a quicker mapping of the surface, sampling and a huge coup for a motor manufacturer, the first Car on Mars.
The Opportunity Rover has travelled 40km in 10 years, a Silverado could run 400km in a couple of days.

Assume that the probability that a person is killed by coronavirus in a year is, independently, 1/(200 million). Assume that the TR population is 100 million. (5 poi. for each parts)
a. Compute P(3 or more people will be killed by coronavirus next year) exactly.
b. Approximate the probability that found in (a).
c. Approximate the probability that ONO or more people are killed by coronavirus within the first 3 months of next year.
d. Approximate the probability that in exactly 3 of next 10 years exactly 4 people are killed by coronavirus. e. Find the expected number of years, among the next 5, in which 2 or more people are killed by coronavirus.

Simmons, Inc., is considering a new 4-year project that requires an initial fixed asset investment of $3.1 million. The fixed asset is eligible for 100 percent bonus depreciation in the first year. At the end of the project, the asset can be sold for $425,000. The project is expected to generate $2.9 million in annual sales, with annual expenses of $940,000. The project will require an initial investment of $475,000 in NWC that will be returned at the end of the project. The corporate tax rate is 24 and the project has a required return of 14 percent. |

What is the NPV of the project? (Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.) |

Quad Enterprises is considering a new three-year expansion project that requires an initial fixed asset investment of $2.29 million. The fixed asset qualifies for 100 percent bonus depreciation in the first year. The project is estimated to generate $1,810,000 in annual sales, with costs of $700,000. The project requires an initial investment in net working capital of $450,000, and the fixed asset will have a market value of $480,000 at the end of the project. |
| a. |
If the tax rate is 25 percent, what is the project’s Year 0 net cash flow? Year 1? Year 2? Year 3? |
| b. | If the required return is 12 percent, what is the project's NPV? |
