A two-lane rural highway, four-leg intersection will have its stop control replaced by a signal control. Compute the expected average total crash frequency (all types, all severities) after the change for the following conditions: 


Expected average crash frequency before change: 23 total crashes/yr
AADT on minor road: 1500 veh/day

AADT on major road: 5000 veh/day 


Please show all work and formulas used. Thanks! Submitting this again this the last person didn't even answer the question at all. Not sure what they were reading.

The composition of "ordinary" Portland cement is 63.82% CaO, 20.56% SiO ₂, 5.50%Al ₂O ₃, 0.76%K ₂O, 0.32% Na ₂O, 0.95% other, and 0.52% insoluble. When mixed with water the resulting cement slurry is basic. Identify three bases of Portland cement and the compounds they form when mixed with water.

Hurricane Harvey caused a net loss of $127 Billion. Let us assume that in any given year the net loss would be the same for the next 10 years (Jan 1, 2020 to Dec 31, 2029) if a Harvey like hurricane were to recur in Houston and adjoining areas. However, if certain investments are made in 2019 to mitigate risks and enhance resilience in the region, the expected loss can be reduced significantly. Let us assume that scientists, engineers and policy experts have worked together to estimate that if the investments are indeed made in 2019 the net loss would reduce to 10% (i.e., $12.7 Billion expected net loss per year over the period from 2020 to 2029 if a hurricane like Harvey were to recur) but additional investments of $ 6.35 Billion would be needed each year to maintain the investments. At the end of 2029 the salvage value of the investments would be 20% of the cost of the original investment. Other than this salvage value there would be no other costs or gains expected after the 10-year period. According to a Presidential tweet at the time, Harvey was a 500-year event. Assuming this probability assessment to be accurate, what present (2019) investment would be justified from a net present worth perspective? Please feel free to make any appropriate assumptions but try to state them clearly.
