Casinos maximize the amount of money that people are willing to put into slot machines by making sure that the slot machines pay out jackpots on a reinforcement schedule that is the most resistant to behavior extinction. these machines use which reinforcement schedule?

a. fixed-ratio
b. variable-ratio
c. variable-interval
d. continuous

B. Variable-ratio                                        

Explanation:

In operant conditioning, there are four types of reinforcement schedules including fixed-ratio, fixed-interval, variable-ratio, and variable-interval.

Variable-ratio schedule: In psychology, the variable-ratio schedule is a reinforcement schedule in whereby a particular response is being reinforced after an uncertain number of responses and creates a high and steady rate of responding. Variable-ratio reinforcement schedule is most resistant to extinction.

Example: Lottery games and gambling.

In the question above, the machines use the variable-ratio reinforcement schedule.

two jet streams that directly affect the formation of weather in the continental part are a polar jet and a subtropical jet. they are responsible for the transportation of weather systems, which directly affect people. the polar front is the boundary between cold air from the north pole and warmer equatorial air. both the polar jet and the subtropical jet blow from the west to the east, and follow the boundary between cold and warm air.

the strongest jet streams are polar jets, while subtropical jets are somewhat weaker.

the right answer is c. the polar jet stream is generaly stronger than the subtropical jet stream.

the language of nature was a manifestation from god as he said "let there be light" and there was light the world began to assume visible, comprehensible form.

what ever we know now think of the old vision of creation we can be sure that with out the speaking of word -without language- we would have no science today with its striking power to illuminate the world.
