3. Ryan asks 80 people to choose a marble, note the color, and replace
the marble in Brianna's bag. Of all random marble selections in this
experiment, 34 red, 18 white, 9 black, and 19 green marbles are selected.
How does the theoretical probability compare with the experimental
probability of drawing a white marble? Lesson 9-3

22.5% hope this helps!

Step-by-step explanation:

1) 18 over 80

2) 18 divided by 80 = .225

3) move the decimal to the right twice

4) answer is 22.5%

yep

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
