A trainer working for the circus trains a lion to jump through a hoop by rewarding small steps (like walking near the hoop, walking through the hoop, and so on) that eventually lead to this desired, more complex behavior. this trainer is using ____________________. shaping classical conditioning observational learning latent learning
The trainer is using the technique of shaping to train the lion to jump through a hoop. Shaping is a method of operant conditioning where desired behaviors are gradually achieved by reinforcing successive approximations of the target behavior.
The trainer is using shaping to train the lion. Shaping involves rewarding small steps or behaviors that are closer and closer to the desired behavior, gradually shaping the lion's behavior towards the ultimate goal of jumping through the hoop. The trainer starts by reinforcing simpler behaviors, such as walking near the hoop, and then progressively rewards more complex behaviors, like walking through the hoop, until the lion successfully jumps through the hoop.
Shaping is a technique derived from operant conditioning, a type of learning where behaviors are strengthened or weakened by the consequences they produce. By using positive reinforcement, in the form of rewards, the trainer motivates the lion to continue exhibiting behaviors that lead to the desired outcome. Through shaping, the lion learns to associate the hoop with positive reinforcement and is gradually shaped to perform the complex behavior of jumping through the hoop.

Answer:
Use all the given information:
Price of a slice in $ - x
Number of slices- 3
Total cost of slices- 3x
Price of chopped cheese in $- 2+x
Number of chopped cheeses- 4
Total cost of chopped cheeses- 8+4x
Total cost- 7x+8
Step-by-step explanation:
We are told that the price of a slice is x and that Dashaun bought 3 slices.
So to find the total amount paid for slices, multiply the price by the number of slices:
\(3*x=3x\)
We are told that the price of chopped cheese is $2 more than a slice. Use y as the cost for chopped cheese:
\(y=2+x\)
Dashaun bought 4 chopped cheeses.
To find the total cost of chopped cheeses bought, multiply the cost per cheese by the amount of cheese purchased:
\(4y\)
Insert the value of y:
\(4(2+x)\)
Use the distributive property:
\(8+4x\)
This is the total cost for the chopped cheeses.
To find the total of lunch, add the prices for the slices and cheeses together:
\(T=3x+8+4x\\\\T=7x+8\)
The total cost for lunch is 7x+8

Which value of x makes the expression above equivalent to 14 Square root 7?
Pls helppppppppppppppp
Answer:
B. 4
Step-by-step explanation:
First, let's evaluate the first expression:\(7 \sqrt{7x} = \sqrt{49 \times 7x} \)
We can just remove the √ from both sides to make it easier to see, so49 × 7x = 343x
Now, let's evaluate the second expression:14√7 = √(1372)
To see what value would make the first expression equal to the second expression, we can divide the the second expression by first expression:1372 ÷ 343 = 4 this is the vaule of x.

Suppose that a department contains 11 men and 15 women. How many ways are there to form a committee with six members if it must have more women than men
There are 183183 ways to form a committee with six members if it must have more women than men.
We need to find the number of ways to form a committee with six members, having more women than men.
We can achieve this in three possible scenarios:
To form a committee with more women than men, we can have either 1, 2, or 3 men on the committee.
We need to calculate the number of ways to form a committee in each of these cases and add them up to get the total number of ways.
Case 1: 1 man and 5 women
We can choose 1 man out of 11 and 5 women out of 15.
The number of ways to do this is:
11C1 * 15C5 = 11 * 3003 = 33033.
Case 2: 2 men and 4 women
We can choose 2 men out of 11 and 4 women out of 15.
The number of ways to do this is:
11C2 * 15C4 = 55 * 1365 = 75075
Case 3: 3 men and 3 women
We can choose 3 men out of 11 and 3 women out of 15.
The number of ways to do this is:
11C3 * 15C3 = 165 * 455 = 75075
Total number of ways = 33033 + 75075 + 75075 = 183183
This gives you the total number of ways to form a committee with six members, with more women than men.

If 1.) Gabby made a scale drawing of the Sam Houston statue in Huntsville, TX. The statue is actually 67 feet tall. Gabby's model used a scale of 1 inch = 20 feet. What was the length of her drawing?
Answer:
3.35 inches
Step-by-step explanation:
Actual height of statue = 67 feets
Scale used : 1 inch = 20 feets
Let Length of drawing = x
1 inch = 20 feets
x inch = 67 feets
Cross multiply to obtain the length of the drawing in inches
20 * x = 67 * 1
20x = 67
x = 67 / 20
x = 3.35 inches
Hence, length of her drawing is 3. 35 inches
Jose can read 7 pages of his book in 5minutes . At this rate how long will it take him to read the entire 175 page book.
Answer:
It will take 125 minutes or 2 hours and 5 minutes.
Step-by-step explanation:
We can use a proportion.
7 pages is to 5 minutes as 175 pages is to x minutes
7 : 5 = 175 : x
7/5 = 175/x
7x = 5 * 175
7x = 875
x = 125
It will take 125 minutes or 2 hours and 5 minutes.

First, we want to note two things:
We have a solid circle at -10, so -10 IS part of the solution.We have shading to the right of -10, meaning we also need to include numbers to the right of -10, or numbers greater than -10.
We can describe this with an inequality: x ≥ -10
Be sure you use ≥ and not >, since -10 is included.
We can describe this with interval notation: [ -10, infty )
Be sure you use [ and not ( on -10, since -10 is included.
You can also use set-builder notation: { x | x ≥ -10 }

Compute the z score for the applicant. Applicant's score 21.0; Mean 18.0; Standard Deviation - 3.0 O2.0 O-10 10 O-20 O None of these
To compute the z-score for the applicant, we can use the formula:
z = (x - μ) / σ
Where:
x is the applicant's score
μ is the mean
σ is the standard deviation
Given that the applicant's score is 21.0, the mean is 18.0, and the standard deviation is -3.0, we can substitute these values into the formula to calculate the z-score.
z = (21.0 - 18.0) / (-3.0)
z = 3.0 / -3.0
z = -1.0
Therefore, the z-score for the applicant is -1.0.
The correct option is O-10.

The required coordinate vector of p(t) = -1 + 15t - 6t^2 relative to B is [2, -2, 3].
The basis for P2 as B = {1 - 4t2, 2 - t, 1 + t - t2}.We need to find the coordinate vector of p(t) = -1 + 15t - 6t2 relative to the basis B of P2.Coordinate vector relative to B means expressing p(t) as a linear combination of the basis vectors, and then finding the scalars (coefficients of the linear combination) and arranging them in a column vector.Consider the vector space P2 consisting of all polynomials of degree less than or equal to 2.Let p(t) be an arbitrary element of P2. Then we need to express p(t) as a linear combination of the given basis vectors, i.e.,p(t) = c1(1 - 4t^2) + c2(2 - t) + c3(1 + t - t^2)where c1, c2, and c3 are scalars. Equating the coefficients of the corresponding powers of t, we get-1 = c1 + 2c2 + c315 = -4c1 - c27 = c1 + c2 - c3Therefore, solving the above equations for c1, c2, and c3, we getc1 = 2, c2 = -2, and c3 = 3.Now, the coordinate vector [P]b of p(t) relative to B is given by[P]b = [2, -2, 3]Hence, the required coordinate vector of p(t) = -1 + 15t - 6t^2 relative to B is [2, -2, 3].Answer: [2, -2, 3].

explain how, in the fewest possible number of moves, you would measure out exactly 1 gallon of water. note that, if you dump out a jug, you have to dump it out completely, that means it is illegal to, for example, fill up the 12-gallon jug and then dump it into both the 3-gallon jug and the 8-gallon to leave behind 1 gallon in the 12-gallon jug.
To measure out exactly 1 gallon of water we need exactly six possible number of moves.
To measure out exactly 1 gallon of water using two jugs, one with a 3-gallon capacity and one with an 5-gallon capacity, you can follow some steps
Fill the 5-gallon jug with water completely. Pour the water from the 5-gallon jug into the 3-gallon jug, leaving 2 gallons of water in the 5-gallon jug.
Empty the 3-gallon jug completely. Pour the 2 gallons of water from the 5-gallon jug into the empty 3-gallon jug.
Fill the 5-gallon jug with water again. Pour water from the 5-gallon jug into the 3-gallon jug until it is full, which will leave exactly 1 gallon of water in the 5-gallon jug.
