Given two original random variables X and Y, suppose that we modify one of them by adding a constant: W = a + X. How does cov(W,Y) compare to cov(X,Y)?a. Use algebra and linearity of the expectation operator to find the answer.b. Explain how the transformation affects the drawing of the scatterplot we used to develop our understanding of covariance, and therefore why the answer to part a. should be expected.
The 20-lb cart B is supported on rollers of negligible size. If a 10-lb suitcase A is thrown horizontally on it at 10 ft/s, determine the length of time that A slides relative to B, and the final velocity of A and B. The coefficient of kinetic fri..
A worker needs to enter a confined space to tighten the packing on a leaking argon valve. Describe two procedures that could be used to isolate the argon line and valve prior to starting work.

A discharge of 2,200 ft^3/sec flows in a trapezoidal channel at a normal depth of 8.0 ft. The channel has a slope of 0.01, a 12-ft bottom width, and side slopes of 1:1 (H:V). Determine the manning coefficient of channel roughness
A sewage treatment works (STW) with 4 single-stage trickling filters has become organically overloaded due to the discharge of a biodegradable industrial effluent to the STW. This is causing effluent to pond on the surface of the filters.
For satisfactory operation, the static pressure at the pump inlet must not be lower than -6 m of water gage. Determine the smallest standard commercial pipe that will give the required performance.
Collar A is dropped 30 inches onto collar B, which is resting on a spring of constant k= 4 lb/in. Assuming perfectly plastic impact (coefficient of restitution e=0), determine the maximum deflection of collar B.
A reverse osmosis plant desalinates 5X10^6 L/day of feedwater containing 1500 mg/L of salts, yielding 3X10^6 L/day of product water with 75 mg?l of salt. What would the salt concentration be in the brine?
