Suppose your neighbors kid comes by to offer you a lottery ticket for the school fundraiser. there are 700 tickets sold and each are $10.

the prizes are as follows:

1st ticket drawn = $500 2nd ticket drawn = $250 3rd ticket drawn = $100

if all 700 tickets are sold, what is your expected value if you buy a ticket?

what is the estimated profit for the school if all 700 tickets are sold?

answer: r there any options?

step-by-step explanation:

the first one

step-by-step explanation:

just id the test.

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
