Let X denotes a randomly chosen student's Midterm 1 score and Y denote his/her Midterm 2 score. Suppose X and Y have the following joint pdf, with scores normalized (lying between 0 and 1): f(x)= (2/7)(3x+4y) 0 < x < 1 and 0 < y < 1 You are asked to provide a prediction “?” of the individual's total score X + Y. The error of prediction is the mean squared error E[(X + Y - ?)^2]. What value of ? minimizes the error of this prediction? In other words, what is your best guess of the student’s total (exam 1+ exam 2) score?
At all other times, the wind velocity is zero. Determine for each case the ration of the total energy available from the wind to the total wind energy available at the mean velocity operating continuously
The depth of the water in the flume is 3m. The average velocity is 1.7m/s. Compute the hydraulic energy at the surface of the water and at the bottom of the flume.
Water occupies the bottom 0.8 m of a cylindrical tank.On top of the water is 0.3 m of kerosene, which is open to the atmosphere. If the temperature is 20 degrees C, what is the gage pressureat the bottom of the tank
A hydraulic jump forms in a horizontal trapezoidal channel. The base width is 4m and the side slopes are 45o. The depths upstream and downstream of the jump are 1m and 3m.
Find the length and width of a square basin for virus disinfection of a flow of 6 MGD. You may assume a depth of 5 ft, a C(dot)t product of 10 (mg/L) (dot)min for 1.5-log removal, and a target free chlorine residual of 0.6 mg/L.
Analyze the frame by moment distribution. Determine all reactions and draw the shear and moment diagrams, locating points of inflection and labeling max and min shear and moment values.
Determine: a. the Level of Service for this segment; b. the loss in Level of Service, if due to construction the lane width is reduced to 10 feet and there are concrete barriers one foot away from either end of the pavement.
The diaphragm is ruptured and fluid fills the entire volume of the vessel. Assume that the fluid is an ideal gas. After you have determined Qsub12, Wsub12, and delta U for the process, calculate the final temperature of the gas.
given: Vf=Vi + a t and Sf=Si + Vi t + 1/2 a t a= 27 ft/sec^2 accelerates from 10 mph to 93 mph in 4.5 seconds designers decided to modify the rise to become the tallest roller coaster in the world, find final velocity in mph if the drop height is ..
Determine the magnitude of P if 10sec is required for the package to travel 5 m up the incline. The static and kinetic coefficients of friction between the package and the incline are both equal to 0.3
Plot the moment envelope curves(positive and negative). (NOTE: You only need to consider maximum positive and negative bending moments even though for a true envelope curve you would have to consider all points between the supports.)
Two capillary tubes have radii of 1 mm and 0.5 mm respectively. They are placed in a liquid whose density is 0.80 g/cc and which completely wets the walls of the tube, i.e. theta = 0. The difference in height of capillary rise is 0.74 cm.
