the entertainment committee at maplecrest junior high school has narrowed down the theme of the spring
dance to three choices. the ten committee members want to conduct a survey to determine which theme
maplecrest's 2000 students prefer. there will be three choices (disco fever, the crazy eighties, or hip hop til
you drop) and the committee will go with the theme that gets the most votes.
which of the following survey methods will allow the committee to make a valid conclusion about which
theme maplecrest's student body prefers?
choose 1
each of the 10 committee members can ask 10 friends to obtain a sample of 100 students.
assign a number to each student, and use a computer program to generate 100 random numbers
between 1 and 2000. ask those students whose numbers are selected.

4 candies

step-by-step explanation:

7 x 28 = 196

200 - 196 = 4 candies remaining.

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

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
