The manager lets you review the receipts used to make the boxplot. The actual numbers of items purchased by the customers in the first 30 minutes the store was open were: 17,18,20,21, 21,22,24,25,26,27,31,33,33,3434, 35,35,37,42,42, 46, and 62. Calculate the following statistics:

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
