Soil signal is found to exceed target signal (due to an aluminum sphere of radius 0.0127 m) in many cases, even for the weakly magnetic Cambodian laterite used in the experiments.
How deep a buried target is detected depends on many other factors in addition to the relative strength of soil and target signals.
The weights used in computing this average correspond to the probabilities in case of a discrete random variable, or densities in case of a continuous random variable.
In mathematics, a sequence is an ordered list of objects (or events).
Like a set, it contains members (also called elements), and the number of ordered element (possibly infinite) is called the length of the sequence.
The guide leads readers through the design of performance assessments by using tools, protocols, and case studies that showcase various entry points and experiences of the schools.You may download and use these tasks for professional development purposes without modifying the tasks.The tasks for grades 3 through High School were developed by the Mathematics Assessment Resource Service (MARS) of the Shell Centre for Mathematical Education, University of Nottingham, England.These tasks are grade-level formative performance assessment tasks with accompanying scoring rubrics and discussion of student work samples.They are aligned to the Common Core State Standards for Mathematics.
