An animal rescue group tracks how their marketing impacts the pet adoptions that occur each year. A record of adoptions for a 12-month period is shown below, in which the adoption status is sorted according to social media use for those cases. Featured on Social Media Not Featured on Social Media Total

Animal adopted 138 76 214

Animal not adopted 78 62 140

Total 216 138 354

Which of the following gives the best evidence of association between social media use and adoption of an animal?
A greater proportion of animals were adopted when social media was used one hundred thirty-eight over two hundred sixteen than when social media was not used seventy-six over one hundred thirty-eight.

The combination of being featured on social media and an animal being adopted occurred more frequently than any other combination.

A total of 138 animals were adopted when social media was used, and only 76 were not adopted when social media was used.

A total of 216 animals were adopted when featured on social media and 138 animals were not.

step-by-step explanation: a

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.

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
