Let x-firm revenue in rubles. Z = X * Y in terms of the dollar Y, if revenue X does not depend on the course Y, and the distribution of X and Y are:

Xi 1000 2000

Pi 0.7 0.3

Yi 25 27

Pi 0.4 0.6

Calculate the expectation in two ways: directly and using the properties of the expectation.

55% are girls and 45% are boys : ) hope this

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
