Step-by-step explanation:

The required measure of the missing angles are m∠1 = 50°, m∠2 = 90°, m∠3 = 60°, m∠4 = 60°, m∠5 = 60°, m∠6 = 60°, and m∠7 = 100°.

Two triangles are said to be congruent if their corresponding sides and angles are equal.

For finding m∠1,

Here m∠2 = 90° as per the figure it is the right angle.

m∠1 + 40° +  m∠2 = 180°

m∠1 + 40° +  90° = 180°

m∠1 = 50°

For finding m∠3,

m∠2 + m∠3 +  30° = 180°

90° +  m∠3 +  30° = 180°

m∠3 = 60°

For finding m∠4 and m∠5

We can see that this triangle is equilateral so, m∠4 = m∠5 = 60°

For finding m∠6 and m∠7

m∠6 + m∠7 +  20° = 180°

60° + m∠7 +  20° = 180°

m∠7 = 100°

Thus, the required measure of the missing angles are m∠1 = 50°, m∠2 = 90°, m∠3 = 60°, m∠4 = 60°, m∠5 = 60°, m∠6 = 60°, and m∠7 = 100°.

Answer:

The answer is B "by permitting Congress to pass any law seen as essential even if it has no link to an enumerated power"

Step-by-step explanation:

What does the Necessary and Proper Clause in the Constitution imply about the powers of Congress?

The Congress shall have Power... To make all Laws which shall be necessary and proper for carrying into Execution the foregoing Powers, and all other Powers vested by this Constitution in the Government of the United States, or in any Department or Officer thereof.

PLZ THANK GIVE FIVE STARS AND GIVE BRAINLIEST:)

Answer:

B, by permitting Congress to pass any law seen as essential even if it has no link to an enumerated power

Step-by-step explanation:

The necessary and Proper clause was created to limit the powers of the government and also for checks and balances so that no other branch has too much control over the others. Therefore the Congress has the power to make laws that are necessary and proper for carrying into execution de foregoing powers.

The argument presented is an example of a fallacy known as affirming the consequent, which incorrectly assumes that if the consequent of a conditional statement is true, then the antecedent must also be true. It fails to consider other possibilities and overlooks the fact that not all square shapes are cubes.

The argument presented is an example of a fallacy known as affirming the consequent, which is a formal logical fallacy. This fallacy occurs when one assumes that if the consequent (the "then" part) of a conditional statement is true, then the antecedent (the "if" part) must also be true.

In this case, the argument incorrectly assumes that because all cubes are square (if cube, then square) and a dice is a cube, then the dice must be square. However, this reasoning is flawed. While it is true that all cubes are square, not all square shapes are cubes. Therefore, even though a dice is a cube, it does not necessarily mean that it must be square.

The argument fails to consider other possibilities, such as the fact that cubes can have other shapes besides squares, like rectangular cubes. This logical error highlights the importance of careful reasoning and avoiding fallacies when making arguments.

Step-by-step explanation:

- 6x + 2y = - 12 → (1)

6x + 5y = 117 → (2)

Add the 2 equations term by term to eliminate the x- term

0 + 7y = 105

7y = 105 ( divide both sides by 7 )

y = 15

Substitute y = 15 into either of the 2 equations and solve for x

Substituting into (2)

6x + 5(15) = 117

6x + 75 = 117 ( subtract 75 from both sides )

6x = 42 ( divide both sides by 6 )

x = 7

solution is (7, 15 ) → a

The function \($$f(x)= \begin{cases}1-x^2 & x \leqslant 1 \\ \ln (x) & x \geqslant 1\end{cases}$$\)  is continuous on (-∞, ∞).

As per the given data the function f(x) is given by:

\($$f(x)= \begin{cases}1-x^2 & x \leqslant 1 \\ \ln (x) & x \geqslant 1\end{cases}$$\)

Here we have to determine that the function f(x) is continuous on (-∞, ∞)

If we show that f(x) is continuous at x = 1 then f(x) is continuous on (-∞, ∞)

What are continuous function?

A continuous function in mathematics is one where changes in the parameter cause constant changes in the function's value (i.e., a change without a leap). This shows that there are no abrupt changes in value or discontinuities.

To show f(x) is continuous at x = 1

\(\lim _{x \rightarrow 1^{-}} f(x)=\lim _{x \rightarrow 1^{+}}\) f(x)

\(\rightarrow \lim _{x \rightarrow 1^{-}} f(x) & =\lim _{x \rightarrow 1^{-}}\left(1-x^2\right) \\\)

= 1 - 1

= 0

\(\lim _{x \rightarrow 1^{+}} f(x) & =\lim _{x \rightarrow 1^{+}} \ln (x) \\\)

= ln 1

= 0

Therefore  \(\lim _{x \rightarrow 1^{+}} f(x) & =\lim _{x \rightarrow 1^{-}} f(x)-0\).

Hence f(x) is continuous on (-∞, ∞)

Based on the given information, we can estimate the probability of receiving the death penalty for the group most likely to receive it by substituting the values of the coefficients into the logistic prediction equation:

P(Y = 1) = exp(a + B1R + B2Y + B3 + B4h + B5i + B6j + B7h*i)

where:

a = -5.26

B1 = 0.00

B2 = 0.17

B3 = 0.00

B4 = 0.91

B5 = 0.00

B6 = 2.02

B7 = 3.98

Assuming that the group most likely to receive the death penalty is a black defendant (h = 1), with a white victim (i = 2), and no additional factors (j = 0), we can plug in these values into the equation:

P(Y = 1) = exp(-5.26 + 0.00R + 0.17Y + 0.00 + 0.911 + 0.002 + 2.020 + 3.981)

P(Y = 1) = exp(-5.26 + 0.91 + 3.98)

P(Y = 1) = exp(-0.37)

Using the exponential function, we can calculate the estimated probability:

P(Y = 1) = 0.691

So, the estimated probability of receiving the death penalty for the group most likely to receive it (a black defendant with a white victim and no additional factors) is approximately 0.691 or 69.1%.

If the constraints B1 = By = B = 0 are used instead, the estimates for the coefficients would be different and would need to be calculated accordingly.

The curves intersect at two points and their angle of intersection is approximately 125.1° and 62.7°.

To find the point of intersection between two curves, we need to solve the system of equations:

t = 3 - s

1 - t = s - 2

3 + t² = s²

Simplifying the second equation, we get:

t + s = 3

Substituting t = 3 - s in the third equation, we get:

s⁴ - 6s³ + 17s² - 24s + 10 = 0

This quartic equation can be solved using numerical methods or factored using the rational root theorem. However, the solutions are rather messy and not easy to obtain by hand. So we'll use a graphing calculator to find the approximate values of s:

s ≈ 2.399, 0.313

Substituting each value of s back into the first equation, we get the corresponding values of t:

When s ≈ 2.399, t ≈ 0.601

When s ≈ 0.313, t ≈ 2.687

So the two curves intersect at approximately two points: (0.601, 0.399, 4.360) and (2.687, -1.687, 0.534).

To find the angle of intersection, we can use the dot product formula:

cosθ = (F'(t) · ū'(s)) / (|F'(t)| |ū'(s)|)

where F'(t) and ū'(s) are the derivatives of the respective curves, and |F'(t)| and |ū'(s)| are their magnitudes.

Differentiating the first curve, we get:

F'(t) = (1, -1, 2t)

Differentiating the second curve, we get:

ū'(s) = (-1, 1, 2s)

So the dot product is:

F'(t) · ū'(s) = -1 - 1 + 4ts

The magnitudes of the derivatives are:

|F'(t)| = √(1 + 1 + 4t²)

|ū'(s)| = √(1 + 1 + 4s²)

Substituting the values of t and s for each point of intersection, we get:

At (0.601, 0.399, 4.360):

cosθ ≈ (-2.398) / (2.440 * 2.248) ≈ -0.527

θ ≈ 125.1°

At (2.687, -1.687, 0.534):

cosθ ≈ (8.542) / (6.144 * 2.784) ≈ 0.459

θ ≈ 62.7°

Therefore, the curves intersect at two points and their angle of intersection is approximately 125.1° and 62.7°.

To find the minimum score required for an A grade, we need to determine the cutoff point that corresponds to the top 13% of scores.

Given that the scores on the test are normally distributed with a mean of 69.5 and a standard deviation of 9.5, we can use the standard normal distribution to calculate the cutoff point. Using a standard normal distribution table or a statistical calculator, we find that the z-score corresponding to the top 13% is approximately 1.04. To find the corresponding raw score, we can use the formula:

x = μ + (z * σ)

where x is the raw score, μ is the mean, z is the z-score, and σ is the standard deviation. Plugging in the values, we have:

x = 69.5 + (1.04 * 9.5) ≈ 79.58

Rounding this to the nearest whole number, the minimum score required for an A grade would be 80. Therefore, a student would need to score at least 80 on the test to achieve an A grade according to the professor's grading scheme.

Cooley's theory emphasizes the role of social interactions and the "looking-glass self," while Mead's theory focuses on the significance of language and symbolic interaction. Charles Horton Cooley's theory of self-development revolves around the concept of the "looking-glass self." Cooley argued that individuals develop their sense of self through social interactions and feedback from others.

According to Cooley, people imagine how they appear to others and interpret their reactions, forming their self-perception based on these social reflections. The looking-glass self emphasizes the influence of social relationships and the perception of others in shaping one's identity.
