The graph stays on a linear line going up to 10000. This graph has a correlation coefficient: Interval of r: -1 ≤ r ≤ 1. The graph has strong linear correlation because the value is close to one. When you square root 0.9952 you get r = 0.9975.

Earthquakes and Subduction Zones Lab Amy Paret Mrs. Igo 9th Grade Periods 3 and 4 Even Date: 2/14/13 Background Research: This lab uses earthquake data to construct profiles of two convergent boundaries: the Tonga Trench and the Peru-Chile Trench. Where two tectonic plates converge‚ if one or both of the plates is an oceanic lithosphere‚ a subduction zone will form. When crust is formed at a mid-ocean ridge‚ it is hot and buoyant meaning it has a low density. As it spreads away from the ridge and

the rotational motion of a particle. It is also called the moment of force. It is always specified with regard to the axis of rotation. On the experiment the axis of rotation serves as the model balance. This means that as much as torque is directly proportional with the force applied on a particle‚ it is also dependent on the perpendicular distance of the applied force to the axis of rotation. On the first activity we need to determine the weight of the pans. At first we had a difficulty or rather

In adult‚ the femoral neck shaft angle is 120-135degrees. We analysed the Femoral Neck Shaft Angle in 50 dry human femur bones. Material and Methods A total of 50 dry femur bones of unknown sex were used for this study. The bones were obtained from the Department of Anatomy‚ Saveetha Dental College and Hospitals.

Also‚ it is specific to the mass and shape of the object‚ including the way that is mass is distributed in the object. Moment of inertia is usually quantified in kgm2. An object’s where the mass is concentrated very close to the center of axis of rotation will be easier to spin than an object of identical mass with the mass concentrated far from the axis of rotation. A common example is to think of an ice skater who

Introduction: The following study may not be true: Studies show that men that are above average in weight are more likely to have a stroke than people with average weight. Steel structured buildings are less likely to fall then brick-structured buildings. How do we interpret this? Explanatory and Response Variables The three Principles that guide Statistics: 1. Plot the data‚ and then add numerical summaries. 2. Look for overall patterns and deviations from those patterns. 3. When there’s a
