Determine how the ABC contingency can be altered to promote more positive behavior. (Option (a) is correct one )

The method that intervention development will be influenced by the ABC data that are gathered on the function of the target behavior is through the determination of how the ABC contingency can be changed to encourage more positive behavior.

By identifying the functional reinforcers that sustain problem behavior, practitioners can create therapies that are more effective (i.e., from a smaller pool of potential interventions to choose from) and efficient.

Linking therapies to the outcomes of functional assessments has become accepted clinical practice and is now covered by both federal and state laws. This represents a significant and advantageous change in the method of behavioral intervention.

Answer:

x = 6

Step-by-step explanation:

To solve the two-step equation 3(x-10)=-12, we need to use inverse operations to isolate the variable x.

First, we will simplify the expression inside the parentheses by distributing the 3.

3(x-10) = -12

3x - 30 = -12

Next, we will add 30 to both sides to isolate the variable term.

3x = 18

Finally, we will divide both sides by 3 to solve for x.

x = 6

Therefore, the solution to the equation 3(x-10)=-12 is x = 6.

{-4 = 7, 5 = 5} = {False, True}

Step-by-step explanation:

The distance between d and f is df = 4.795.

Given,

We are assuming e=d and df as the distance between d and f.

d(-7,-2) and f(11,3)

We need to find the distance of df.

The distance between two points (x_1, y_1) and (x_2, y_2) is given by:

\(\sqrt{(x_{2}- x_{1} )+ (y_{2} -y_{1}) }\)

We have,

d(-7,-2) and f(11,3)

x_1 = -7

x_2 = 11

y_1 = -2

y_2 = 3

df = \(\sqrt{(11-(-7))+(3-(-2))}\)

   Removing the brackets inside the square root

   = square root ( 11 + 7) + ( 3 + 2 )

   = square root (18 + 5)

   = square root 23

The square root of 23 is 4.795.

   = 4.795

Answer:

D. 9x² - 12x - 1

Explanation:

To find f(g(x)), we need to replace x by g(x) as follows:

f(x) = x² - 5

f(g(x)) = (g(x))² - 5

Then, g(x) is equal to -3x + 2, so replacing g(x) by (-3x + 2), we get:

f(g(x)) = (g(x))² - 5

f(g(x)) = (-3x + 2)² - 5

f(g(x)) = (-3x)² + 2(-3x)(2) + 2² - 5

f(g(x)) = 9x² - 12x + 4 - 5

f(g(x)) = 9x² - 12x - 1

Answer:

Step-by-step explanation:

A quadrilateral can be inscribed in a circle only if the sum of its opposite angles is equal to 180°, so:

7x - 15 + 3x + 15 = 180°      and      2(17y - 10) + 13y + 12 = 180°

     10x = 180°                                  34y - 20 + 13y + 12 = 180°

       x = 18°                                             47y = 188°

                                                                   y = 4°

m∠M:  2(17•4 - 10) = 2•58° = 116

m∠N:   7•18 - 15 =126 - 15 = 111

m∠O:   13•4 + 12 = 52 + 12 = 64  

m∠P:    3•18 + 15 = 54 + 15 = 69

The coordinates of the midpoint of AB are (-5/2, 9).

Since the line through (-3,8) is parallel to u=2x-3, it has the same slope of 2. We can find the equation of the line passing through (-3,8) with slope 2 using point-slope form:

y - 8 = 2(x + 3)

y = 2x + 14

Now we can find the coordinates of the points A and B where this line intersects the curve (x+3)(y-2) = 8 by substituting y = 2x+14 into the equation:

(x+3)(2x+12-2) = 8

\(2x^2 + 10x - 5 = 0\)

Using the quadratic formula, we get:

\(x = (-10 + \sqrt{(160)} )/4\\x = (-5 + \sqrt{10} )/2\)

Therefore, the points A and B have x-coordinates of \((-5 + \sqrt{10} )/2\) and \((-5 - \sqrt{10} )/2\), respectively. To find the y-coordinates of A and B, we substitute these values of x into the equation y = 2x + 14:

\(y_A = 2(-5 + \sqrt{(10)} )/2 + 14 = -5 + \sqrt{(10)} + 14 = 9 + \sqrt{(10)} \\y_B = 2(-5 - \sqrt{(10)} )/2 + 14 = -5 - \sqrt{(10)} + 14 = 9 - \sqrt{(10)}\)

The midpoint of AB has coordinates

\(((-5 + \sqrt{(10)} )/2 + (-5 - \sqrt{(10)} )/2)/2 = -5/2 and (9 + \sqrt{(10)} + 9 - \sqrt{(10)} )/2 = 9.\)

In terms of probability, we can say that the probability of selecting a coffee maker with a defective cord is 5.0% or 0.05. The percentage of coffee makers with a defective cord.

To find the probability of a coffee maker having a defective cord, we'll use the given information about faulty switches and defective cords.

We know that:
1. 6.0% of coffee makers have either a faulty switch or a defective cord.
2. 1.5% have a faulty switch.
3. 0.5% have both defects.

Using the formula for the probability of the union of two events (A or B) - P(A ∪ B) = P(A) + P(B) - P(A ∩ B), where A represents the event of a faulty switch, B represents the event of a defective cord, and A ∩ B represents both defects:

P(A ∪ B) = 6.0% (either a faulty switch or a defective cord)
P(A) = 1.5% (faulty switch)
P(A ∩ B) = 0.5% (both defects)

We need to find P(B), the probability of a coffee maker having a defective cord.

Using the formula, we can write:
6.0% = 1.5% + P(B) - 0.5%

Now, we'll solve for P(B):
6.0% = 1.0% + P(B)
P(B) = 6.0% - 1.0%
P(B) = 5.0%

Therefore, the probability (percent) of a coffee maker having a defective cord is 5.0%.

The solution for the simultaneous of equations 4x + 7y = 40 and 4x + 4y = 4 by elimination are x = -11, y = 12

we shall write the equations as:

4x + 7y = 40...(1)

4x + 4y = 4...(2)

subtract equation (2) from (1) to eliminate x

4x + 7y - 4x - 4y = 40 - 4

3y = 36

divide through by 3

y = 12

put the value 12 for y in equation (1) to get

4x + 7(12) = 40

4x + 84 = 40

4x = 40 - 84 {subtract 84 from both sides}

4x = -44

divide through by 4;

x = -11

The length of the ribbon can be expressed as (2x + 2x + 2) inches, and its value depends on the value of x.

Let's start by calculating the length of ribbon needed for the first pillow. The side length of the square pillow is given as 2x + 2 inches. Since the ribbon is sewn along the perimeter, the length of the ribbon needed is equal to the perimeter of the pillow. The perimeter of a square is calculated by adding up the lengths of all four sides. In this case, the perimeter is 2x + 2 + 2x + 2 + 2x + 2 + 2x + 2, which simplifies to 8x + 8 inches.

For the second pillow, the side length is given as 4x - 7 inches. Using the same logic, we can calculate the length of ribbon needed as the perimeter of the second pillow, which is 4x - 7 + 4x - 7 + 4x - 7 + 4x - 7. Simplifying this expression gives us 16x - 28 inches.

To find an expression that represents the length of ribbon needed for both pillows, we can set up a proportion based on the ratio of their side lengths. We have (2x + 2) / (4x - 7) = (8x + 8) / (16x - 28). We can solve this proportion to find the value of x, and then substitute it back into either expression to find the length of ribbon needed.

Answer:

Part A: The proposed route does not meet requirement because it is longer than the maximum required length of 3 miles

Part B: For the total distance is as close to 3 miles as possible, the start point of the parade should be at the point on Broadway with coordinates (9.941, 4.970)

Part C: The coordinates of the cameras stationed half way down each road are;

For central avenue; (4, 2)

For Broadway; (7.97, 2.49)

Step-by-step explanation:

Part A: The length of the given route can be found using the equation for the distance, l, between coordinate points as follows;

\(l = \sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}\)

Where for the Broadway potion of the parade route, we have;

(x₁, y₁) = (12, 3)

(x₂, y₂) = (6, 0)

\(l_1 = \sqrt{\left (0 -3\right )^{2}+\left (6-12 \right )^{2}} = 3 \cdot \sqrt{5}\)

For the Central Avenue potion of the parade route, we have;

(x₁, y₁) = (6, 0)

(x₂, y₂) = (2, 4)

\(l_2 = \sqrt{\left (4 -0\right )^{2}+\left (2-6 \right )^{2}} = 4 \cdot \sqrt{2}\)

Therefore, the total length of the parade route =-3·√5 + 4·√2 = 12.265 unit

The scale of the drawing is 1 unit = 0.25 miles

Therefore;

The actual length of the initial parade =0.25×12.265 unit = 3.09 miles

The proposed route does not meet requirement because it is longer than the maximum required length of 3 miles

Part B:

For an actual length of 3 miles, the length on the scale drawing should be given as follows;

1 unit = 0.25 miles

0.25 miles = 1 unit

1 mile =  1 unit/(0.25) = 4 units

3 miles = 3 × 4 units = 12 units

With the same end point and route, we have;

\(l_1 = \sqrt{\left (0 -y\right )^{2}+\left (6-x \right )^{2}} = 12 - 4 \cdot \sqrt{2}\)

y² + (6 - x)² = 176 - 96·√2

y² = 176 - 96·√2 - (6 - x)²............(1)

Also, the gradient of l₁ = (3 - 0)/(12 - 6) = 1/2

Which gives;

y/x = 1/2

y = x/2 ..............................(2)

Equating equation (1) to (2) gives;

176 - 96·√2 - (6 - x)² = (x/2)²

176 - 96·√2 - (6 - x)² - (x/2)²= 0

176 - 96·√2 - (1.25·x²- 12·x+36) = 0

Solving using a graphing calculator, gives;

(x - 9.941)(x + 0.341) = 0

Therefore;

x ≈ 9.941 or x = -0.341

Since l₁ is required to be 12 - 4·√2, we have and positive, we have;

x ≈ 9.941 and y = x/2 ≈ 9.941/2 = 4.97

Therefore, the start point of the parade should be the point (9.941, 4.970) on Broadway so that the total distance is as close to 3 miles as possible

Part C: The coordinates of the cameras stationed half way down each road are;

For central avenue;

Camera location = ((6 + 2)/2, (4 + 0)/2) = (4, 2)

For Broadway;

Camera location = ((6 + 9.941)/2, (0 + 4.970)/2) = (7.97, 2.49).

This exercise is necessary to use the given map information and then make the distance between points, in this way we find that:

A)The proposed route does not meet requirement because it is longer than the maximum required length of 3 miles.

B) Broadway and Cedar Street

C) \(Central \ Avenue(4, 2)Broadway (7.97, 2.49)\)

So from the distance between points and the informed map we have:

A) The equation for the distance, as follows:

\(l=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}\)

Where for the Broadway potion of the parade route, we have:

\((x_1,y_1)=(12,3)\\(x_2,y_2)=(6,0)\)

Applying the values ​​in the formula given above, we have:

\(l_1=\sqrt{(0-3)^2+(6-12)^2}=3\sqrt{5}\)

For the Central Avenue potion of the parade route, we have:

\((x_1, y_1) = (6, 0)(x_2, y_2) = (2, 4)\)

Applying the values ​​in the formula given above, we have:

\(l_2=\sqrt{(4-0)^2+(2-6)^2}=4\sqrt{2}\)

Therefore, the total length of the parade route:

\(3\sqrt{5} + 4\sqrt{2} = 12.265 \\0.25*12.265 unit = 3.09\ miles\)

B) The two streets that are the same distance apart are the streets: Broadway and Cedar Street.

C) The coordinates of the cameras stationed half way down each road are:

For Central Avenue:

\(Camera \ location = ((6 + 2)/2, (4 + 0)/2) = (4, 2)\)

The speed of the boat is approximately 9.21 km/h.

In order to ascertain the speed of the boat, we must find out the number of kilometers traversed by it and the amount of time taken for traveling that distance.

The traveled distance by the boat is equal to the space between two points,

or the magnitude of (final position vector - initial position vector),

which in this case is (-7i - 3j). Hence, the total distance of sqrt((-7)^2 + (-3)^2) kilometers is obtained.

Regarding the amount of time taken to travel that predetermined distance, it computes to be 2 hours 45 minutes, or 2.75 hours.

Therefore, through simple division, the speed of the boat can be determined at roughly 9.21 km/h, which results when you divide the traveled distance of sqrt(58) by the time taken in hours, that is, 2.75.
