determinant method

It is not possible to measure directly the potential developed at interface of the metal gas and its ions in solution using voltmeter. Hence the electrode whose single electrode potential has to be determined is coupled with another electrode of known potential and the emf of the cell is..

So far we have learnt how to construct a mathematical model for a linear programming problem. If we can find the values of the decision variables x 1 , x 2 , x 3 , ..... x n , which can optimise (maximize or minimize) the objective function Z, then we say that these values of x i are the optimal so..

could be known and the height of the electric pole be determined. This method is called Triangulation method..

A teacher wishes to know whether there is any relationship between the hours of study and the test scores of the students. Ten students were selected randomly and were given a test. Test the hypothesis that there is a significant relationship between hours of study and test scores at α = 0.01..

State whether the system is consistent and independent, consistent and dependent, or inconsistent using Elimination method. 7 x + y = 8 y - 7 z = 50 8 x + 8 z = - 48 => Cannot be determined or Consistent and dependent or Inconsistent or Consistent and independent..

State whether the system is consistent and independent, consistent and dependent, or inconsistent using elimination method. 5 x - 2 y + z = 10 x + y + z = 2 14 x + 6 z = - 3 => cannot be determined or inconsistent or consistent and dependent or consistent and independent..

State whether the system is consistent and independent, consistent and dependent, or inconsistent using Elimination method. 3 x - 3 y + z = 9 x + y + z = 3 18 x + 12 z = - 4 => Inconsistent or Consistent and dependent or Consistent and independent or Cannot be determined..

State whether the system is consistent and independent, consistent and dependent, or inconsistent using Elimination method. x - 13 y - 168 z = - 170 13 x + y = 144 z 12 x + 36 z = 183 - 15 y => Consistent and independent or Cannot be determined or Consistent and dependent or Inc..

State whether the system is consistent and independent, consistent and dependent, or inconsistent using Elimination method. x 4 + 4 y + z 4 = - 15 4 x 4 - y 4 = 6 z 4 x + z = 4 => Cannot be determined or Consistent and dependent or Consistent and independent or Inconsistent..

State whether the system is consistent and independent, consistent and dependent, or inconsistent using Elimination method. 8 x 7 + y 8 = z + 1 1 5 x 4 9 - 8 z 4 9 = - 1 x - y 8 = z 7 - 8 => Consistent and dependent or Cannot be determined or Inconsistent or Consistent and Indep..
