Draw a coordinate plane on your paper and graph the following using intercepts. x+2y = 6 2x-y= 4​

Answer:fixed ratio

Step-by-step explanation: :)

This is an illustration of a fixed ratio reinforcement schedule: after a predetermined number of responses, Frances is given a reward (in this case, $1). (every pound of worms).

An example of a reinforcement plan utilized in the behavioral psychology concept of operant conditioning is a fixed ratio reinforcement schedule. A reward or reinforcement is delivered according to this schedule after a predetermined number of actions or responses. As an illustration, a rat might receive a food pellet after every 10 lever presses.

Fixed ratio schedules work well for encouraging high response rates since the subject is driven to keep up the activity in order to earn the reward. Yet, if the reinforcement is stopped, the behavior can become less frequent or cease entirely.

Fixed ratio schedules can also cause behaviors to become rigid or stereotyped because the subject may start concentrating only on the number of responses required to earn the reward and stop considering other options or actions.

Overall, fixed ratio reinforcement regimens can be helpful in teaching both humans and animals to carry out particular tasks, but they should be utilized with caution and consideration for any unexpected consequences.

21. Break the bracket out, we get : 5(2x + 3) = 5.2x + 5.3 = 10x + 15
a is exactly alike, b is a bit longer but can be simplified as 10x + 15, so answer is a and b

22. Break the bracket of b, we get : 2(2x-4) = 2.2x - 2.4 = 4x - 8
b is exactly alike, c is a bit longer but also can be simplified as 4x-8, so b and c

23. Break the bracket of c, we get : 4(3x-4) = 4.3x - 4.4 = 12x - 16, and this is the only answer that is right.

24. Break the bracket, we get : 2(6x + 1/2) = 2.6x + 2.1/2 = 12x + 1, and b is also the only right answer

Step-by-step explanation:

The average of a sum and the sum of the averages are not same.

The average of a sum is mean of sum of data. Total sum divided by total number of sum.

Whereas , The sum of the average is sum of mean of data. Total sum of averages of data.

These two terms are not same.

For example : Assume x₁ , x₂ , x₃ , . . . , xₙ be a data

S₁ , S₂ , . . . , Sₙ be sum of data

A₁ , A₂ , . . . , Aₙ be average of data

where n is total number of sum of data

The Average of sum will be = S₁ + S₂ + . . . + Sₙ / n

The sum of average will be = A₁ + A₂ + . . . + Aₙ

Hence, The average of sum and Sum of average are different.

Therefore, the maximum blood pressure of 200 mmHg occurs at approximately 0.524 seconds, and the minimum blood pressure of 120 mmHg occurs at approximately 1.571 seconds within the time interval 0 ≤ t ≤ 0.75.

To find the maximum and minimum values of the blood pressure function p(t), we need to examine the behavior of the sinusoidal term, -40sin(3t), within the given time interval. The function is a sine wave with an amplitude of 40 and a period of 2π/3. This means that the maximum value occurs at the peak of the sine wave (amplitude + offset), and the minimum value occurs at the trough (amplitude - offset).

The maximum blood pressure corresponds to the peak of the sine wave, which is 40 + 160 = 200 mmHg. To find the time at which this occurs, we set the argument of the sine function, 3t, equal to π/2 (since the peak of the sine wave is π/2 radians). Solving for t gives t = (π/2) / 3 = π/6 ≈ 0.524 seconds.

Similarly, the minimum blood pressure corresponds to the trough of the sine wave, which is -40 + 160 = 120 mmHg. Setting the argument of the sine function equal to 3π/2 (the trough of the sine wave), we find t = (3π/2) / 3 = π/2 ≈ 1.571 seconds.

Therefore, the maximum blood pressure of 200 mmHg occurs at approximately 0.524 seconds, and the minimum blood pressure of 120 mmHg occurs at approximately 1.571 seconds within the time interval 0 ≤ t ≤ 0.75.

even if an independent variable has an effect on the dependent variable, it fail to reject the null hypothesis and make a type II error

Even if a treatment is effective in the real world (it has an effect), it is still possible to obtain a sample mean that is so similar to the population mean that the sample mean doesn't fall in the critical, or rejection, region. If this happens, you are likely to fail to reject the null hypothesis and make a type II error.

Since that sample mean is so similar to the population mean, the treatment effect may not be detected on analysis even though it is in fact significant, this will cause the research to erroneously concluded that the treatment effect is zero and accept the null hypothesis when it is actually not zero. This is a type II error. Type II error in statistics means the non-rejection of a false null hypothesis and type I error is the rejection of a correct null hypothesis.

The solution x = -9 is correct and satisfies the equation 10x = -90 using the multiplication principle.

The given equation is 10x = -90

To solve for x using the multiplication principle,you need to divide both sides of the equation by 10.

10x/10 = -90/10x = -9

After performing the division, you will get the value of x to be -9.

This is your solution to the equation 10x = -90.

However, you need to perform a check to verify that the solution is correct.

To perform a check, substitute the value of x back into the original equation:

10x = -90(10) (-9) = -90

The left-hand side is equal to 10 times -9 which is -90, and the right-hand side is equal to -90.

Since both sides are equal, the solution x = -9 is correct and satisfies the equation 10x = -90.

The answer choice which should fill the blank in the task content is; Sometimes.

The maximum value of a linear objective function sometimes occurs at exactly one vertex of the feasible region.

It follows from the task content that the maximum value of a linear function is established as occuring at the vertex of the feasible region; however, it is required to determine if this is always, never or sometimes.

When the graph of a system of inequalities, usually the constraint inequalities forms a region that is closed, the region is said to be bounded and the region is termed the feasible region as all constraints are satisfied in this region.

Furthermore, If the linear programming problem can be optimized, an optimal (minimum or maximum) value will occur at one of the vertices of the region representing the set of feasible solutions.

However, more than one vertex may produce the maximum value; hence, the correct answer choice is; sometimes.

shaded area = (area of the regular hexagon - area of the regular pentagon (the hexagon is shaded while the pentagon is not therefore you would subtract the area of the hexagon by the area of the pentagon))+(area of the square- area of the triangle( same reason as the hexagon and pentagon the triangle is not shaded therefore creating a gap in the square)

The number of students who attended the previous six classes is an example of a discrete probability distribution.

A discrete probability distribution refers to a probability distribution where the random variable can only take on a finite or countable number of distinct values. In the given options, the number of students who attended the previous six classes fits this criteria and can be considered a discrete probability distribution.

In this scenario, the random variable represents the number of students attending the classes, and it can only take on specific whole number values (e.g., 0, 1, 2, 3, and so on). Each value has a corresponding probability associated with it, representing the likelihood of that specific number of students attending the classes.

The distribution of the number of students who attended the previous six classes can be analyzed using concepts such as probability mass functions and cumulative distribution functions. It allows us to calculate probabilities for different outcomes, assess the likelihood of specific attendance numbers, and make informed decisions based on the distribution's characteristics.

Other options mentioned, such as the recruitment of volunteers for a charity drive, the distribution of salaries, and car speeds, are not discrete probability distributions. The recruitment of volunteers and the distribution of salaries involve continuous variables and are better suited for continuous probability distributions. Car speeds, on the other hand, can also be modeled using continuous distributions due to the infinite number of possible speed values along a neighborhood street.
