The more lottery tickets you buy, the greater your chances of winning. However, you have no way of knowing how many tickets you will have to buy before you win. It might be fewer than ten; it might be more than a million. This is an example of which type of schedule of reinforcement?

Variable - Ratio Schedule

Step-by-step explanation:

Schedules of reinforcements are guidelines which give insight as to what actions would be rewarded. They are used as teaching tools. There are basically two types of reinforcements and they are the Continuous and Partial reinforcements.

While the Continuous reinforcements are teaching methods which explain that a response is met with an equal outcome consistently, the Partial reinforcements are used after the lessons are established as in the case of continuous reinforcement. In Partial reinforcements, the response is met with an outcome inconsistently.

In variable - ratio schedules, there is a reinforcement of response after an unknown number of responses. In the lottery game above, no one knows ( unknown response), how many tickets a player has to buy before he is rewarded (outcome/reinforcement). So the outcome/reward is inconsistent and the response is unknown.

use the power rule  

( a b ) n = a n b n

to distribute the exponent.

apply the product rule to  

3 x 2 y 3 . ( 3 x 2 ) 2 ( y 3 ) 2

apply the product rule to  

3 x 2 . 3 2 ( x 2 ) 2 ( y 3 ) 2

raise  

3

to the power of  

2 . 9 ( x 2 ) 2 ( y 3 ) 2 multiply the exponents in   ( x 2 ) 2

.

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 2 ⋅ 2 ( y 3 ) 2

multiply  

2   by   2 . 9 x 4 ( y 3 ) 2

multiply the exponents in  

( y 3 ) 2 .

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 4 y 3

⋅

2

multiply  

3   by   2 . 9 x 4 y 6

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
