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).
What is a fixed ratio reinforcement schedule?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.

Find the sum of the finite arithmetic sequence.
Sum of the first 80 positive odd integers
Answer:
6400
Step-by-step explanation:
We have 1 + 3 + 5 + ... + 155 + 157 + 159.
We can use Gauss's strategy.
Since we are adding 80 numbers, there are 40 pairs. Each pair adds up to 1 + 159 = 160. (Notice that 3 + 157, 5 + 155 = 160)
Thus, because there are 40 pairs and each pair adds up to 160, we have 160 * 40 = 6400.

What is Precession? Group of answer choices
Deviations in the circularity of the orbit
Changes in the rate of Earth's Spin
Changes in the magnitude of the angle of tilt
Changes in the orientation of the axis of rotation
Precession is a phenomenon that refers to the gradual and continuous change in the orientation of the Earth's rotational axis over long periods of time.
This shift in the orientation of the axis of rotation results in changes in the position of the celestial pole with respect to the stars, which causes a shift in the apparent position of stars over time. The precession of the Earth's axis is caused by the gravitational forces of the Sun, Moon, and other planets in the solar system.
Precession is characterized by changes in the magnitude of the angle of tilt, which causes changes in the rate of the Earth's spin. As the axis of rotation moves, it causes the length of the day to change over time. Additionally, deviations in the circularity of the orbit also affect the precession of the Earth's axis.
Precession is a significant phenomenon in astronomy and has been observed for thousands of years. It has important implications for studies of astronomy, geology, and climate change. For instance, precession affects the timing of the seasons and has a significant impact on the Earth's climate. It also affects the orientation of the Earth's magnetic field, which has important implications for navigation and communication systems.
In conclusion, precession is the gradual change in the orientation of the Earth's rotational axis, caused by the gravitational forces of the Sun, Moon, and other planets. It results in changes in the magnitude of the angle of tilt, changes in the rate of Earth's spin, and deviations in the circularity of the orbit. Precession has significant implications for various fields of study, including astronomy, geology, and climate change.

Using the substitution method, find the solution to this system of equations. Be sure to show your work!
-2x+2y=7
-x+y=4
please show a breakdown of the equation and a correct answer! thanks.
Answer:
To solve the given system of equations using the substitution method, we need to solve one equation for one variable and then substitute that expression into the other equation for that same variable. Let's solve the second equation for y.
-x + y = 4
y = x + 4
Now we can substitute this expression for y into the first equation and solve for x.
-2x + 2(x + 4) = 7
-2x + 2x + 8 = 7
8 = 7
The equation 8 = 7 is not true, which means the system of equations has no solution. We can see this visually by graphing the two lines. They are parallel and will never intersect, which means there is no point that satisfies both equations.
Therefore, the solution to the system of equations is "No solution."

Evaluate
\int_{C}^{ }x^2yzds
where C is the line segment from (0, 1, 1) to (3, 0, 6)??
The value of the line integral ∫(C) x²yz ds over the given line segment is 9√(35)/4.
To evaluate the given line integral, we need to parameterize the line segment from (0, 1, 1) to (3, 0, 6) and then integrate the function over that parameterization.
Let's parameterize the line segment using a parameter t that ranges from 0 to 1:
x = 3t
y = 1 - t
z = 1 + 5t
Now, we can express the line integral as follows:
∫(C) x²yz ds = ∫(C) (3t)² (1 - t) (1 + 5t) ds
To evaluate this integral, we need to express ds in terms of dt. We can use the arc length formula:
ds = √((dx/dt)² + (dy/dt)² + (dz/dt)²) dt
Plugging in the parameterizations, we have:
dx/dt = 3
dy/dt = -1
dz/dt = 5
ds = √((3)² + (-1)² + (5)²) dt
= √(9 + 1 + 25) dt
= √(35) dt
Now, we can rewrite the integral:
∫(C) x²yz ds = ∫(0 to 1) (3t)² (1 - t) (1 + 5t) √(35) dt
Simplifying the integrand:
∫(C) x²yz ds = ∫(0 to 1) 9t² (1 - t) (1 + 5t) √(35) dt
= 9√(35) ∫(0 to 1) (t² - t³ + 5t³ - 5t⁴) dt
= 9√(35) ∫(0 to 1) (6t³ - 5t⁴ - t³) dt
= 9√(35) ∫(0 to 1) (5t³ - 5t⁴) dt
Integrating each term:
= 9√(35) [5 * (t⁴ / 4) - 5 * (t⁵ / 5)] evaluated from 0 to 1
= 9√(35) [5/4 - 5/5]
= 9√(35) [25/20 - 20/20]
= 9√(35) (5/20)
= 9√(35) (1/4)
= 9√(35)/4

Hence, x < -2Consider a game in which two players, each has to choose a non-negative integer, that is, anything from {0,1,2,…}. If both players choose the same number, they each get that number in dollars. Otherwise, the player who chooses the higher number gets the lower number plus $1. And the person who chooses the lower number gets the lower number. (a) Describe all the Nash equilibria in this game. (b) Suppose now the rules remain as above, excepting in the case where one person chooses a number less than or equal to 10 and the other chooses a number greater than 10 . Then they both get 0 . Describe all the Nash equilibria of this game.
In the original game, there are infinitely many Nash equilibria, as any pair of numbers chosen by the players where neither player can increase their payoff by unilaterally changing their choice is a Nash equilibrium.
However, the most commonly studied Nash equilibrium in this game is for both players to choose 0.
In the modified game, where one person choosing a number less than or equal to 10 and the other choosing a number greater than 10 results in both players receiving 0, there are two Nash equilibria: one where both players choose 0 and another where both players choose numbers greater than 10.
Explanation:
(a) In the original game, let's consider the case where both players choose the same number, let's say x. In this case, both players receive x dollars, and neither player can increase their payoff by changing their choice. Therefore, any pair of numbers where both players choose the same number is a Nash equilibrium.
(b) In the modified game, if one player chooses a number less than or equal to 10 and the other chooses a number greater than 10, both players receive 0. In this case, neither player can increase their payoff by unilaterally changing their choice, as both players will still receive 0. Therefore, the Nash equilibria in this game are pairs of numbers where both players choose 0 or pairs of numbers where both players choose numbers greater than 10.
Overall, the original game has infinitely many Nash equilibria, while the modified game has two Nash equilibria: one where both players choose 0 and another where both players choose numbers greater than 10.

What is the solution for the system of equations? use the substitution method to solve. 2x + y = 20
−5y = −6x + 12
Using the substitution method the solution for the system of equations is (x, y) = (7, 6).
The given system of equations is:
2x + y = 20 ---(1)
−5y = −6x + 12 ---(2)
We can use the substitution method to solve this system of equations.
Step 1: Solve one of the equations for one of the variables in terms of the other variable.
Let's solve equation (2) for y:
−5y = −6x + 12
Divide both sides by -5:
y = (6/5)x - 12/5
Step 2: Substitute the expression we found for y into the other equation and solve for x.
Substitute (6/5)x - 12/5 for y in equation (1):
2x + (6/5)x - 12/5 = 20
Multiply both sides by 5 to get rid of the denominator:
10x + 6x - 12 = 100
Combine like terms:
16x = 112
Divide both sides by 16:
x = 7
Step 3: Substitute the value of x into one of the original equations and solve for y.
Let's use equation (2) since we already solved for y in terms of x:
−5y = −6(7) + 12
−5y = −30
Divide both sides by −5:
y = 6
Therefore, the solution for the system of equations is (x, y) = (7, 6).

Consider the quadratic polynomial ax 2 bx c. suppose the coefficients are given by rolling a fair die three times. what is the probability that the roots of the polynomial are equal?
Complete the square to write
ax² + bx + c = a (x + b/(2a))² - (b² - 4ac)/(4a)
The quadratic has a double root at x = -b/(2a) if the constant term (b² - 4ac)/(4a) vanishes, which happens if b² - 4ac = 0.
Let A, B, and C be random variables representing the value of the first, second, and third roll of the die. They are independent and identically distributed with PMF
Pr [X = x] = 1/6
if x ∈ {1, 2, 3, 4, 5, 6}, and 0 otherwise.
We want to find
Pr [B² - 4AC = 0]
Note that
B² - 4AC = 0 ⇒ B² = 4AC ⇒ (B/2)² = AC
which tells us that B must be even, and also that AC is a perfect square. Then there are 5 possible outcomes that satisfy the conditions:
• If B = 2, then AC = 1 ⇒ A = C = 1
• If B = 4, then AC = 4 ⇒ A = 1, C = 4 or A = C = 2 or A = 4, C = 1
• If B = 6, then AC = 9 ⇒ A = C = 3
and there are 6³ = 216 total possible outcomes in the sample space. So,
Pr [B² - 4AC = 0] = 5/216

(i) It is impossible to provide an example for the statement "C = {(x, y) ∈ R² |x² + y² = 1} is an uncountable set" in 15 to 20 words.
To prove that the set C = {(x, y) ∈ R² |x² + y² = 1} is an uncountable set, we can use the Cantor's diagonal argument. Suppose, for contradiction, that C is countable.
This means we can list all the elements of C in a sequence, such as C = {(x₁, y₁), (x₂, y₂), (x₃, y₃), ...}. Now, consider constructing a point (a, b) that is not in the list. We can do this by choosing a ≠ xᵢ and b ≠ yᵢ for each i.
Since (a, b) is not in the list, it contradicts the assumption that C contains all the points (x, y) satisfying x² + y² = 1. Therefore, C must be uncountable.
