The main criticism of differential opportunity theory is that it overlooks the fact that most delinquents become law-abiding adults (option c).

Differential opportunity theory, developed by Richard Cloward and Lloyd Ohlin, focuses on how individuals in disadvantaged communities may turn to criminal activities as a result of limited legitimate opportunities for success.

However, critics argue that the theory fails to account for the fact that many individuals who engage in delinquency during their youth go on to become law-abiding adults.

This criticism highlights the idea that delinquent behavior is not necessarily a lifelong pattern and that individuals can change their behavior and adopt prosocial lifestyles as they mature.

While differential opportunity theory provides insights into the relationship between limited opportunities and delinquency, it does not fully address the complexities of individual development and the potential for desistance from criminal behavior.

Critics suggest that factors such as personal growth, social support, rehabilitation programs, and the influence of life events play a significant role in individuals transitioning from delinquency to law-abiding adulthood.

Answer: Each wheel makes 437.5 revolutions in 20 mins

Step-by-step explanation:

Circumference = 2πr

Given that the radius is 40 cm

Circumference = 2π(40) = 80π cm

Find the distance traveled in 20 mins

Speed = 66 km/h

1 hour = 66 km

Rewrite hour into min

60 min = 66 km

1 min = 66 ÷ 60 = 1.1 km

Rewrite km in cm

1.1 km = 1.1 x 10,000 cm = 110,000 cm

Find the number of revolutions in 20 mins:

1 revolution = 80π cm

Number of revolution = 110,000 ÷ 80π = 437.5

The price of each plastic bead is $0.75 and the price of each metal bead is $1.25.

Let's assume the price of a plastic bead is 'p' dollars and the price of a metal bead is 'm' dollars.

We can create a system of equations based on the given information:

Equation 1: 7p + 5m = 7.25 (from the first bracelet)

Equation 2: 9p + 3m = 6.75 (from the second bracelet)

To solve this system of equations using elimination, we'll multiply Equation 1 by 3 and Equation 2 by 5 to make the coefficients of 'm' the same:

Multiplying Equation 1 by 3:

21p + 15m = 21.75

Multiplying Equation 2 by 5:

45p + 15m = 33.75

Now, subtract Equation 1 from Equation 2:

(45p + 15m) - (21p + 15m) = 33.75 - 21.75

Simplifying, we get:

24p = 12

Divide both sides by 24:

p = 0.5

Now, substitute the value of 'p' back into Equation 1 to find the value of 'm':

7(0.5) + 5m = 7.25

3.5 + 5m = 7.25

5m = 7.25 - 3.5

5m = 3.75

Divide both sides by 5:

m = 0.75

Therefore, the price of each plastic bead is $0.75 and the price of each metal bead is $1.25.

Answer:

12:15 pm.

Step-by-step explanation:

If Mrs. Morales' Spanish class starts at 11:25 am and is 50 minutes long, it will end 50 minutes after it starts.

To find the end time, you can add 50 minutes to the start time of 11:25 am.

11:25 am + 50 minutes = 12:15 pm

Therefore, Mrs. Morales' Spanish class ends at 12:15 pm.

Answer: 1/5 * 1/4 = a

Step-by-step explanation: Ok, so 5/5 = 1 whole. So that is the reason why the square is divided into 20 small squares. Dividing fractions is the same as multiplying by its recriplical. Ex. 2 divided by 1/4. First we would do 2/1 divided by 1/4, since a whole can be put on top of 1. So in your case that would be 4/1. Then we do 2/1 * 4/1. As you can see 1/4 is flipped because dividing is the same as multiplying by the reciprocal. So in your case that would be 1/5 * 1/4 = a

Both statements 1 and 2 are false.

Statement 1: ∀x ∈ Z+, [(2x + 1 > 3) ⋁ (2x^2 – 1 ≥ 1)]

To evaluate this statement, we need to consider all positive integers (Z+) and check if either of the conditions within the brackets is true for each value of x. However, upon closer examination, we can see that neither condition is satisfied for any positive integer. For the first condition, 2x + 1 > 3, no positive integer value of x makes this inequality true. Similarly, for the second condition, 2x^2 – 1 ≥ 1, none of the positive integers satisfy this inequality. Therefore, statement 1 is false.

Statement 2: ∃x ∈ Z, [(x^2 – 1 < 0) ∧ (2x - 2 ≥ 0)]

In this statement, we are looking for the existence (∃) of an integer (Z) value of x that satisfies both conditions within the brackets. For the first condition, x^2 – 1 < 0, we need to find an integer value of x for which this inequality holds true. However, there are no integer solutions to this inequality. For the second condition, 2x - 2 ≥ 0, we can rewrite it as 2(x - 1) ≥ 0, which is true when x ≥ 1. Since we couldn't find any integer value of x that satisfies both conditions simultaneously, statement 2 is also false.

Therefore, both statement 1 and statement 2 are false.

The radius of convergence of a power series function is a positive real number R that determines the interval of values for which the power series converges.

It represents the distance from the center of the power series expansion, within which the series converges. The radius of convergence is determined by the properties of the coefficients in the power series. Specifically, it is defined as the reciprocal of the limit superior of the absolute values of the coefficients. Mathematically, if we have a power series function of the form:

f(x) = ∑(n=0 to ∞) aₙ(x - c)ⁿ

where aₙ represents the coefficients and c is the center of the series, then the radius of convergence R is given by:

R = 1 / lim sup |aₙ|^(1/n)

The power series converges for all values of x within the interval (c - R, c + R). If |x - c| > R, the series diverges.

It's important to note that the radius of convergence can be zero, indicating that the power series only converges at the center point (x = c), or it can be infinite, indicating that the series converges for all values of x.

To find the area of the resulting surface when the curve x^(2/3) y^(2/3) = 9 is rotated about the y-axis within the interval 0 ≤ y ≤ 27, we can use the surface area formula for revolution.

The area can be computed by integrating the surface area element along the curve and then evaluating the integral over the given interval.

To calculate the surface area, we use the formula for the surface area of revolution, which states that the surface area is equal to the integral of 2πy ds, where ds represents the infinitesimal element of integral along the curve.

First, we rewrite the equation x^(2/3) y^(2/3) = 9 in terms of y to isolate y: y = (9/(x^(2/3)))^(3/2).

Next, we calculate ds using the formula for arc length: ds = √(1 + (dy/dx)^2) dx.

Taking the derivative of y with respect to x, we find dy/dx = \((-9x^(-5/3))/(2x^(-1/3)) = -9/(2x).\)

Substituting this value into the expression for ds, we have ds = √(1 + (-9/(2x))^2) dx.

Now, we can set up the integral for the surface area:

Surface Area = ∫[from x = 1 to x = 27] 2πy ds

Substituting the expressions for y and ds, the integral becomes:

Surface Area = ∫[from x = 1 to x = 27] \(2π(9/(x^(2/3)))^(3/2) √(1 + (-9/(2x))^2)\)dx.

Evaluating this integral will give us the area of the resulting surface.

There are 92,378 different assignments of pollsters to houses where two pollsters will canvas a neighborhood with 20 houses.

There are 20 houses to choose from for the first pollster, and then 19 houses remaining for the second pollster.

However, since the order in which the pollsters visit the houses does not matter, we need to divide by the number of ways of arranging the 10 houses that each pollster will visit evaluated using probability.

Therefore, the total number of different assignments of pollsters to houses is:

(20 choose 10) * (10 choose 10) / 2! = (184,756) * (1) / 2 = 92,378

So there are 92,378 different assignments of pollsters to houses.

The surface area  of an art project having the height of the cone is 28 inches and its diameter is 14 inches is approximately 635 square inches to the nearest square inch.

To find the surface area of the cone, we need to find the slant height first.

Using the Pythagorean theorem, we can find the slant height:

r = diameter/2 = 14/2 = 7 inches
s = sqrt(r^2 + h^2) = sqrt(7^2 + 28^2) = 29 inches (approx)

Now we can find the surface area of the cone:

surface area = pi*r*s = 3.14*7*29 = 643.46 square inches (approx)

Therefore, the surface area of the covering to the nearest square inch is 643 square inches.

To find the surface area of the paper covering the cone, you'll need to consider both the lateral surface area and the base area.

However, since the base is not covered in paper, we'll only need to calculate the lateral surface area.

Given the height of the cone is 28 inches and its diameter is 14 inches, we can find the radius (r) as half of the diameter: r = 14 / 2 = 7 inches.

To find the lateral surface area, we need the slant height (l). We can use the Pythagorean theorem for this: l² = r² + h²
l² = 7² + 28²
l² = 49 + 784
l² = 833
l = √833 ≈ 28.84 inches

Now, we can calculate the lateral surface area (A) using the formula: A = π * r * l
A ≈ 3.14 * 7 * 28.84
A ≈ 634.5 square inches
