Arandom sample of 184 students at south high school were surveyed on whether they would prefer going to a movie or a concert. the results are shown in the relative frequency table. which statements are correct? check all that apply. a) the marginal relative frequency for 10th graders is 0.18. b) 42% of the students prefer a concert over a movie. c) a greater ratio of 11th graders prefer a concert to a movie. d) more 12th graders were surveyed than any other grade level. e) the difference in the percent of students who prefer a movie over a concert is16%.

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
