(Not sure if what I put is correct I need help!) To the right are four of the top officials in a region's government a. List the possible samples without replacement of size 3 that can be obtained from the population of four officials(Hint There are 4 possible samples.) If simple random sample without replacement of three officials is taken from the four officials , determine the probability the following officials are in the sample . b. The governor , secretary of defense , and treasurer C. The governor and treasurer d. The governor

a is the right answer

47 - 90 = 43

43 - 180 = x

x = 137

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
