During the first 13 weeks of the television season, the Saturday evening 8:00 p. m. to9:00 p. m. audience proportions were recorded as ABC 29%, CBS 28%, NBC 25%, and independents18%. A sample of 300 homes two weeks after a Saturday night schedule revisionyielded the following viewing audience data: ABC 95 homes, CBS 70 homes, NBC89 homes, and independents 46 homes. Test with α=.05 to determine whether the viewingaudience proportions changed.

it would be 6xy and -16xy.

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
