This table shows the dollar amount customers have in their bank account. which expression would give the best estimate of the total amount in the accounts?

200+400+500+800
200+500+600+800
300+500+500+800
300+500+600+900

i think the second one would be the best estimate.

the rule for rounding is 5+ you would go up and 4 below you would round down, so:

221 -> 200

485 -> 500

562 -> 600

833 -> 800

therefore, 200+500+600+800 is the answer

add the table and i will answer correctly

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
