Paul and Micheal sell magazine subscriptions by telephone. Paul is paid $1.00 for every five calls he makes, while Mike is paid$1.00 for every subscription he sells, regardless of the number of calls he makes. Paul's telephoning is reinforced on a <u>fixed-interval</u> schedule, whereas Mike's is reinforced on a <u>variable-ratio</u> schedule.
<h3><u>What is a fixed-interval timetable?</u></h3>
The initial response is rewarded only after a predetermined period of time has passed in fixed-interval schedules. This schedule results in rapid responses near the end of the interval but slower responses right after the reinforcer are given. A fixed-interval (FI) schedule consists of two parts:
- It calls for the passage of a certain amount of time before reinforcement will be supplied in response to a response, and
- No response during the interval is reinforced; only the first response after the interval's completion is reinforced.
<h3><u /></h3><h3><u>What is the variable-ratio schedule?</u></h3>
A schedule of reinforcement known as a variable ratio schedule rewards a behavior after a predetermined number of responses. High, consistent response rates are the result of this type of timetable. Because they believe that the subsequent reaction might be the one they need to receive reinforcement, organisms are persistent in responding.

a. 50 cents
Contribution margin per unit is price per unit- variable cost per unit
1.75 - ($50,000/40,000 units)
1.75 - 1.25 = $ .50
b. $8750
Margin of safety is the expected sales - break even sales
(45,000 units * $1.75 per unit) - (40,000 *1.75)
78,750 - 70,000 = $8750
Answer:
B) In its rulings, the NLRB has allowed employee empowerment in certain very limited situations.
Explanation:
Employee empowerment refers to a company giving its employees a higher degree of autonomy and independence regarding their normal work related activities.
Personally I don't understand how employee empowerment can affect employees negatively but unions tend to oppose it unless they are directly involved in the empowerment process.
Answer:
The thief has a 0.11% probability of hitting the pin code on the first try.
Explanation:
Simply, if the ATM card has a 3-digit code that can be repeated, and the board has 9 numbers (for example, from 1 to 9), we must start from the smallest number that could be formed with these numbers to the highest number that these numbers could also compose, which in the case would be 111 and 999. Then, 889 different numbers could be formed (it is the distance between 111 and 999), with which the possibility of hitting the key to the first attempt would be 1 in 889 times, or 1/889.
To take the probability to a percentage, we must know that 889 / 8.89 gives 100. Therefore, dividing 1 / 8.89 we will know the percentage of probabilities of hitting the key on the first attempt: 1 / 8.89 = 0.11.
This shows us that the thief has a 0.11% probability of hitting the key on the first try.
