Figure 5.4 shows details of a mass stone rubble retaining wall which has a unit weight of 20 kN/m³. The retained soil has a level surface and carries a uniform surcharge, w, with a mean value of 15 kN/m² and a standard deviation of 2.5 kN/m². 6 m 5.0 2m 1m ·2··C·0's = 15kN/m² . My = 20kN/m³ M = 40°. 0₁ Fig. 5.4 Example 5.12 The retained soil is granular with the following properties: mean value = 20 kN/m³; s.d. = 1.5 kN/m³ s.d. = 1.5° Unit weight: Angle of friction: mean value = 40°; The foundation soil is granular and its angle of friction has a mean value of 40° and a standard deviation of 3º. The coefficient of friction of the base of the wall and the foundation soil, μ, can be assumed to be equal to the tangent of the angle of friction of the foundation soil. Assuming that the back of the wall is smooth and using Rankine's formula for K₁, determine the reliability index against sliding.

I want to examine the relationship between gas mileage of cars and the engine size (displacement in cubic inches). Which explanatory variable is Engine size Gas mileage Relationship between the two Both engine size and gas mileage Neither engine size nor gas mileage

2. The data table below shows the instantaneous velocity of a car every 5 minutes. Use simpson's rule to determine the displacement of the car in the first 30 minutes. What is the average speed of the car for the entire 30 minutes? Time (min) Velocity (m/s) 25 5 28 10 32 15 30 20 29 25 26 30 23

Japan's high population density has resulted in a multitude of resource-usage problems. One especially serious difficulty concerns waste removal. The article "Innovative Sludge Handling Through Pelletization Thickening"t reported the development of a new compression machine for processing sewage sludge. An important part of the investigation involved relating the moisture content of compressed pellets (y, in %) to the machine's filtration rate (x, in kg-DS/m/hr). Consider the following data. 125.4 98.3 201.6 147.2 146.0 124.5 112.3 120.2 161.1 178.8 y 77.9 76.9 81.3 80.0 78.1 78.5 77.4 77.2 79.9 80.4 159.4 145.7 74.9 151.5 144.2 124.8 198.6 132.6 159.6 110.7 79.7 79.2 76.9 78.1 79.6 78.3 81.7 76.8 79.1 78.5 Relevant summary quantities are X; = 2817.4 Fy, = 1575.5, 5x? = 415,815.84, Fxy, = 222,698.08, Fy? = 124,149.53.
