We are going to rewrite both numbers:
 (4.2 × 10 ^ 6) = 4200000
 (2.25 × 10 ^ 5) = 225000
 Adding we have:
 4200000 + 225000 = 4425000
 Rewriting in exponential notation we have:
 4425000 = 4,425 * 10 ^ 6
 Answer:
 
(4.2 × 10 ^ 6) + (2.25 × 10 ^ 5) is equal to:
 
4,425 * 10 ^ 6

gogolik [260]

Answer:

d. Variable ratio

Step-by-step explanation:

We are asked to determine that gambling at a slot machine is an example of which reinforcement schedule.

Let us see our given choices one by one.

b. Fixed interval

We know that in fixed interval schedule the first response is rewarded only after a specified amount of time has elapsed. An example of fixed interval schedule is weekly paycheck.

c. Variable interval

We know that in variable interval schedule, the reinforcement is delivered at changing and unpredictable intervals of time.

d. Variable ratio

In variable ratio schedule, a response is reinforced after an unpredictable number of responses. Gambling and lottery are examples of variable ratio.

Therefore, option 'd' is the correct choice.
