One of Pryor's 10 Laws of shaping is D. Train one behavior at a time is one of Pryor's 10 Laws of shaping. This law emphasizes the importance of focusing on one behavior at a time when shaping behavior.

By doing so, the trainer can avoid confusing the animal and can more effectively reinforce the desired behavior. This law also helps the trainer to break down complex behaviors into smaller, more manageable parts, which can then be shaped individually.

According to Karen Pryor's 10 Laws of Shaping, one of the key principles is to train one behavior at a time. This is important because it helps the learner to focus on mastering a specific behavior without getting overwhelmed or confused by multiple tasks.

By concentrating on one behavior at a time, the trainer can provide clear, consistent reinforcement and feedback, which increases the likelihood of successfully shaping the desired behavior.

Overall, following this law can lead to more successful shaping and training outcomes.

The average number of left-handed people from the simulations is 10.8. The number 10 is consistent with the actual percentage of left-handedness, which is 10 percent.

Conducting the simulation:First, the simulation of left-handedness is conducted according to the description provided

The simulation was conducted on a random sample of 150 people. The simulated percentage of left-handedness was 9.33 percent. This percentage is different from the 10 percent real value.

The simulated percentage is lower than the real value. A simulation of 150 people is insufficient to generate a precise estimate of left-handedness. The percentage may be off by a few percentage points. It is impossible to predict the exact outcome of a simulation.

The results of a simulation may deviate significantly from the real value. The discrepancy between the simulated and actual percentage of left-handedness could have occurred due to a variety of reasons. A simulation can provide an estimate of a population's parameters.

However, the simulation's estimate will be subject to errors and inaccuracies. A sample's size, randomness, and representativeness may all have an impact on the accuracy of a simulation's estimate.

Repeating the simulation:Based on the instructions provided, the simulation is repeated ten times.

The number of left-handed people in each of the ten simulations is recorded. The results of the ten simulations are as follows:

16, 9, 11, 9, 13, 10, 10, 10, 10, and 10.

The average number of left-handed people from the simulations is 10.8. The number 10 is consistent with the actual percentage of left-handedness, which is 10 percent.

Based on the simulation's results, it is not improbable to choose 15 individuals at random and not find any left-handed people. It is possible because the number of left-handed people varies with each simulation.

The percentage of left-handed people from the simulation is not very close to the actual value. This is because a simulation's accuracy is affected by the sample's size, randomness, and representativeness. The simulation was repeated ten times to obtain a more accurate estimate of left-handedness. The average number of left-handed people from the simulations is 10.8, which is consistent with the actual percentage of 10%.

Answer:

a) 6x³ − 5x² − 39x + 35

b) no

Step-by-step explanation:

(2x^3 − 5) (3x² + 5x − 7)

Distribute:

3x² (2x − 5) + 5x (2x − 5) − 7 (2x − 5)

Distribute again:

6x³ − 15x² + 10x² − 25x − 14x + 35

Combine like terms:

6x³ − 5x² − 39x + 35

5x − 2 is the opposite of 2x − 5, so you would get the negative of the answer from part (a).

Answer:

We have, 14% × x = 15

or, 14100 × x = 15

Multiplying both sides by 100 and dividing both sides by 14,

We are given v = ds/dt, v = 9.8t + 9, s(0) = 17. We need to find the position of a body moving along a coordinate line at time t.

Using the formula of velocity, we can integrate it with respect to t to find the position of the body at any time t. The formula for velocity is:v = ds/dt... (1) Integrating equation (1) with respect to t, we get's = ∫vdt + C ...(2)

Here, C is the constant of integration, and it is found using the given initial position. Given, s(0) = 17Substitute s = 17 and t = 0 in equation (2).17 = ∫(9.8t + 9)dt + C [∵ s(0) = 17]17 = 4.9t² + 9t + C

Therefore, C = 17 - 4.9t² - 9tOn substituting the value of C in equation (2), we get:s = ∫vdt + 17 - 4.9t² - 9t ...(3)Now, we can substitute the given velocity, v = 9.8t + 9, in equation (3).s = ∫(9.8t + 9)dt + 17 - 4.9t² - 9ts = 4.9t² + 9t + 17 - 4.9t² - 9ts = 9t + 17

The total length between the two fences is 136 ft, and the total cost is 164.56 dollars.

We have a square garden with a perimeter of 60ft. Then if the sidelength of the square is S, we have that:

60ft = 4*S

S = 60ft/4 = 15ft

We know that the first fence is around the perimeter of the garden, so the length of the first fence is exactly 60ft.

Now, the other fence is 2ft away from the first fence, so it forms a square of sidelength of:

15ft + 2*2ft = 19ft

Then the perimeter of this square is:

P = 4*19ft = 76ft

This means that the length of the second fence is 76 ft.

So the total length of fence is 76ft + 60ft = 136ft

And the cost is $1.21 per ft, then the total cost for the fence is:

The given information describes a parallelogram GRPC with point B between C and P, forming triangle GCB. The lengths of the sides of triangle GCB are as follows: GC = 375 ft, CB = 325 ft, and GB = 425 ft.

Point E is outside the parallelogram, and segments BE and PE form triangle BPE. The length of BP is given as 225 ft. To find the length of EP, we can use the triangle proportionality theorem. According to this theorem, if a line is drawn parallel to one side of a triangle, it divides the other two sides proportionally.

In this case, since BP is parallel to GR, we can set up the following proportion:
BP / BE = GR / GE

Substituting the given lengths, we have:
225 / BE = 375 / GE

Solving for GE, we find:
GE = (375 * BE) / 225

Now, to find the length of EP, we can use the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

In triangle BPE, the sum of BP and BE is greater than EP. Therefore:
BP + BE > EP
225 + BE > EP

Finally, to find the length of EP, subtract BE from both sides of the inequality:
225 > EP - BE
225 + BE > EP

In conclusion, the length of EP is greater than 225 ft, but we cannot determine the exact length without knowing the value of BE. This is the main answer.

Step-by-step explanation:

The distance travelled in a velocity time graph as shown in the image is the area of the shape. As such, considering the first 14 seconds, the distance covered will be computed by finding the area of the shape.

Note that the shape to be considered ends t the 14 seconds mark. This shape is a trapezium. The area of  a trapezium is given as

A = 1/2(a + b) h

where a and b are the parallel sides of the trapezium and h is the height As such, the distance covered in the first 14 seconds

= 1/2 (14 + 10) * 8

= 4 * 24

= 96m

What is ascending order?

Suppose there is a series of numbers. The numbers will be in ascending order if the numbers are arranged from their least value to their greatest value.  

The sorting of numbers in ascending order plays a very important role in statistics for calculation of median, quartiles, decile and percentile.

Here,

4.79 = 4.79

\(4\frac{19}{28} = 4 + \frac{19}{28} = 4.68\\\)

\(4,\bar{8} = 4.8888..... = 4.89\)

\(-\sqrt{25} = -5\)

-5< 4.68< 4.79< 4.89 is in ascending order

Answer:

14.81%

Step-by-step explanation:

A fair six-sided dice has a total of six sides meaning that there are 6 possible outcomes for each dice roll. If two of the faces on the dice are red, then the possibility of rolling a red on a single dice roll would be 2/6, while the probability of rolling anything else would be 4/6 because there are 4 other sides left. Now if we roll three seperate dice, in order to calculate the probability of getting only one red face we need to multiply the probability of getting a red face on the first dice by the probability of the other two dice getting anything else.

2/6 * 4/6 * 4/6 = 32/216 or 0.1481

Answer:

There are 7 1/5 rest stops in the 5 mile race.

Step-by-step explanation:

To solve this you just have to divide 5 by 5/6. To do this you have to first turn 5 into an improper fraction, which would be 36/6. After that you need to switch 5/6 so its 6/5 and you also need to change the division sign to a multiplication sign. Next, you can cross cancel the 6 in both 36/6 and 6/5 so they change to 36/1 and 1/5. Then you just multiply across and you should get 36/5. To change the improper fraction into a mixed number you have to divide 36 and 5 so then you'll get 7 with a remainder of 1 and then you can make 7 the whole number and then make 1 be the numerator and 5 the denominator so you get 7 1/5.
