Wes and Libbie each surveyed groups of students to find whether they would prefer going to an art museum or to the zoo. Wes found that 90% of the students he surveyed wanted to go
to the zoo. Libbie found that 60% of the students she surveyed wanted to go to the zoo. When
the teachers surveyed all the students, they found that 62% wanted to go to the zoo. Which of
these most likely explains why Wes's data were so different than the other two surveys?

-2

7 - 9 = -2

reversed:

-2 + 9 = 7

a precentage of 6th graders. the population is all 6th graders. let me know if i'm wrong, i hope this ! : )

step-by-step explanation:

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
