Maya is playing a trivia game with multiple choice questions. Each question has 222 correct answers among 555 answer choices. Maya has no idea what the answers to a certain question are, so she needs to choose two different answers at random. What is the probability that maya's first guess is correct and her second guess is incorrect? round your answer to two decimal places.
The probability that maya's first guess is correct and her second guess is incorrect is 0.24
From the question given above, the following data were obtained:
Correct answer (C) = 222Total answer = 555Incorrect answer (I) = 555 – 222 = 333Next, we shall determine the probability that her 1st guess is correct.
Correct answer, nC = 222Total answer, nS= 555Probability of correct answer, P(C) =?P(C) = nC / nS
P(C) = 222 / 555
Next, we shall determine the probability that her 2nd guess is incorrect
Incorrect answer, nI = 333Total answer, nS = 554Probability of incorrect answer, P(I) =?P(I) = nI / nS
P(I) = 333 / 554
Finally, we shall determine the probability that her first guess is correct and her second guess is incorrect.
Probability of correct answer, P(C) = 222 / 555Probability of incorrect answer, P(I) = 333 / 554Probability of 1st correct and 2nd incorrect, P(C n I) =?P(C n I) = P(C) × P(I)
P(C n I) = (222 / 555) × (333 / 554)
P(C n I) = 0.24

____________ reinforcement occurs if a behavior is only reinforced some of the time. A. Continuous b. Positive c. Intermittent d. Negative.
Answer:
Its c! Intermitted
Explanation:
I took the test
Intermittent reinforcement occurs if behavior is only reinforced some of the time. The correct option is c.
What is Intermittent reinforcement?Delivering rewards at irregular periods is known as intermittent reinforcement. This technique has been shown to elicit the most effort from the subject.
The subject is rewarded at what appears to be random intervals, rather than every time they exhibit a desirable behavior or in accordance with any set plan. In order to enhance the trauma bond, which is the result of the victim's extreme emotional experience as she battles for her life and looks to the abuser for approval, intermittent reinforcement is used.
Positive reinforcement, negative reinforcement, extinction, and punishment are the four different types of reinforcement.
Therefore, the correct option is c. Intermittent.

From the given graph, from the ground floor to the third floor is a rapid acceleration.
During the unload at the third floor, the velocity was constant until all the passengers was unloaded.
The deceleration of the elevator was slower than the acceleration because it occurred at a longer time.
Thus, we can conclude that the graph correctly represents the story illustrated in the graph.

Newton’s law of cooling states that for a cooling substance with initial temperature t0, the temperature t(t) after t minutes can be modeled by the equation t(t)=ts+(t0−ts)e−kt, where ts is the surrounding temperature and k is the substance’s cooling rate. A liquid substance is heated to 80°c. Upon being removed from the heat, it cools to 60°c in 15 min. What is the substance’s cooling rate when the surrounding air temperature is 50°c? round the answer to four decimal places. 0. 0687 0. 0732 0. 0813 0. 872.
The cooling rate of the substance is approximately 0.0732.
According to the statement, the Newton's law of cooling is defined by the following formula:
[tex]T(t) = T_{s} + (T_{o}-T_{s})\cdot e^{-k\cdot t}[/tex] (1)
Where:
[tex]T_{s}[/tex] - Final temperature, in degrees Celsius.[tex]T_{o}[/tex] - Initial temperature, in degrees Celsius.[tex]t[/tex] - Time, in minutes.[tex]k[/tex] - Cooling rate, in [tex]\frac{1}{min}[/tex].[tex]T(t)[/tex] - Current temperature, in degrees Celsius.Please notice that substance reaches thermal equilibrium when [tex]T(t) = T_{s}[/tex], that is when temperature of the substance is equal to the temperature of surrounding air.
If we know that [tex]T_{o} = 80\,^{\circ}C[/tex], [tex]t = 15\,min[/tex], [tex]T_{s} = 50\,^{\circ}C[/tex] and [tex]T(15) = 60\,^{\circ}C[/tex], then the cooling rate of the substance is:
[tex]60 = 50 + (80 - 50)\cdot e^{-15\cdot k}[/tex]
[tex]\frac{60-50}{80-50}= e^{-15\cdot k}[/tex]
[tex]\frac{1}{3} = e^{-15\cdot k}[/tex]
[tex]k = -\frac{1}{15}\cdot \ln \frac{1}{3}[/tex]
[tex]k \approx 0.0732[/tex]
