Apen is dropped on a hardwood floor and a 1 is recorded if the pen crosses a line and a 0 if it does not. estimate the probability that the pen crosses a line in a single drop. 1 1 1 0 1 0 0 1 0 0 1 1 1

a. 3/13

b. 5/13

c. 5/8

d. 8/13

D. 8/13

Step-by-step explanation:

Of the 13 drops, the pen crossed a line 8 times (there are 8 1's).  So the probability is 8/13.

answer: what in the world is 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
