Answer:
Jimmy’s behavior is being controlled by <u>negative reinforcement</u>.
Explanation:
Jimmy does not expect a reward after taking out the garbage. All he wants is to stop his uncle from nagging. This characterizes negative reinforcement, which is the type of reinforcement that happens when a behavior is strengthened by the desire to avoid or stop a negative outcome or aversive stimulus. Jimmy will be more likely to take out the garbage in the future (behavior) to avoid his uncle's constant requests (aversive stimulus).
Answer:
10 minutes
Explanation:
Mika can eat 21 hot dogs in 6 minutes and she wants to know how many minutes it will take her to eat 35 hot dogs.
This is a problem that can be used establishing a ratio. We know that she can eat 21 hot dogs in 6 minutes, therefore her ratio would be: 
Now if she wants to know how many minutes it will take her to eat 35 hot dogs we can establish another radio where x will be the number of minutes it will take her: 
Since the problem tells us that she can keep up the same pace when eating the 35 hot dogs, <u>we can make those two radios equal to one another and solve for x: </u>

Thus, it will take her 10 minutes to eat 35 hot dogs.
