What is accuracy and error rate? In principle yes, accuracy is the fraction of properly predicted cases thus 1-the fraction of misclassified cases, that is error (rate). Also note that test error rate implies error on a test set, so it is likely 1-test set accuracy, and there may be other accuracies flying around. How […]
How do you set a fitness goal?
How do you set a fitness goal? How to Set Realistic Fitness Goals You’ll Actually Achieve, According to Top Trainers Focus on one goal at a time. Make it your own. Make it measurable, specific, and time-bound. Set the bar low—at least, at first. Play the long game. Understand what’s driving your goal. Be flexible […]
What will be the equi valent resistance of the resistor R1 R2 connected in parallel?
What will be the equi valent resistance of the resistor R1 R2 connected in parallel? Likewise, if three or more resistors each with the same value are connected in parallel, then the equivalent resistance will be equal to R/n where R is the value of the resistor and n is the number of individual resistances […]
Can the Pauli exclusion principle be violated?
Can the Pauli exclusion principle be violated? Pauli exclusion principle will NEVER be violated by any physical object. There will be a finite space between any two object even at angstrom level. In material, this is called lattice parameter. No matter how much you apply the force, lattice parameter or space between any two object […]
What is the formula for relative velocity?
What is the formula for relative velocity? Key Equations Position vector →r(t)=x(t)^i+y(t)^j+z(t)^k Relative velocity equation connecting two reference frames →vPS=→vPS′+→vS′S Relative velocity equation connecting more than two reference frames →vPC=→vPA+→vAB+→vBC Relative acceleration equation →aPS=→aPS′+→aS′S What is relative velocity Class 11 formula? Relative Velocity xB (t) = xB (0) + vB t. Displacement from object A […]
What kind of image is created by a concave lens?
What kind of image is created by a concave lens? virtual images Can a concave lens produce a real image? Plane mirrors, convex mirrors, and diverging lenses can never produce a real image. A concave mirror and a converging lens will only produce a real image if the object is located beyond the focal point […]
Which is the best example of parasitism?
Which is the best example of parasitism? Examples of Parasitism: Fleas or ticks that live on dogs and cats are parasites. They are living off of the blood of the host animal. Lice are another type of parasite. What is the relationship between isopods and fish? The relationship between a fish and an isopod is […]
What are the consequences of not labeling specimens correctly?
What are the consequences of not labeling specimens correctly? Unquestionably, the most serious consequence of specimen labeling errors on the direct care of patients is of one of the following types: Failure to provide proper and immediate care to a patient based on the lack of accurate test results associated with the proper patient. What […]
What are the similarities of electricity and magnetism?
What are the similarities of electricity and magnetism? Electricity and magnetism are closely related. Flowing electrons produce a magnetic field, and spinning magnets cause an electric current to flow. Electromagnetism is the interaction of these two important forces. What is the relationship between electric and magnetic fields? Electricity and magnetism are two related phenomena produced […]
What is needed for heat transfer by radiation?
What is needed for heat transfer by radiation? Radiation is a method of heat transfer that does not rely upon any contact between the heat source and the heated object as is the case with conduction and convection. This is a type electromagnetic radiation . No mass is exchanged and no medium is required in […]
