Answer:

m∠2 = m∠7 ( ): Alternate Exterior angles theorem

m∠7 + m∠8 = 180° ( ) : linear pair theorem

Step-by-step explanation: I got it right

The missing statements which prove that ∠2 and ∠8 are supplementary angles are Alternate exterior angles theorem and Linear pair theorem.

Linear pair of angles are the pair of angles formed when two lines are intersected at a point forming on a line.

Sum of the measures of angles of linear pair is supplementary.

Given that,

Lina a is parallel to line b.

Both lines are intersected by transversal t.

Here, ∠2 and ∠7 are alternate exterior angle.

By the "Alternate Exterior Angles Theorem", the alternate exterior angles formed by two parallel lines intersected by a transversal are equal.

So, m∠2 = m∠7 [By Alternate Exterior Angles Theorem]

∠7 and ∠8 are angles formed on a line. That is, they are linear pair of angles.

By "Linear pair theorem", linear pair of angles are supplementary.

So, m∠7 + m∠8 = 180° [Linear pair theorem]

Hence the blanks are Alternate exterior angles theorem and Linear pair theorem.

Answer:

x = 32

Step-by-step explanation:

Three angles have been shown in the figure which are located at a point of a straight line.

By the property of angles on a straight line,

Sum of the angles shown = 180°

(3x - 20)° + 30°+ (2x + 10)° = 180°

(3x + 2x) + ( -20 + 30 + 10) = 180

5x + 20 = 180

5x = 180 - 20

5x = 160

x = \(\frac{160}{5}\)

x = 32

Therefore, x = 32 will be the answer.

Answer:

\(x = 32 \: \: degrees\)

Step-by-step explanation:

Angels in a straight line =180°

\(3x - 20 + 30 + 2x + 10 = 180 \\ 5x + 20 = 180 \\ 5 x = 180 - 20 \\ 5x = 160 \\ \frac{5x}{5} = \frac{160}{5} \\ x = 32\)

If William spends a winter day recording the temperature once every three hours for science class. If  the temperature dropped 9.1°F. Between 3pm and 6pm, the temperature dropped 5°F. The temperature at 6pm is: -11.1°F

Between 9am and noon, the temperature rose 16.2°F, so the temperature at noon will be:

Temperature at noon  = -12.2 + 16.2

Temperature at noon  = 3.0°F

Between noon and 3pm, the temperature dropped 9.1°F, so the temperature at 3pm will be:

Temperature at 3pm = 3.0 - 9.1

Cov(X,Y) = E[XY] - E[X]E[Y] = 0, and so Corr(X,Y) = Cov(X,Y) / (sd(X) * sd(Y)) = 0. X and Y are not independent. we have shown that P(X > 0, Y > 0) ≠ P(X > 0) * P(Y > 0), which means X and Y are not independent. Another way to see this is to note that if X is known, then Y is restricted to the interval (-√(1-x^2), √(1-x^2)) due to the constraint 2+y^2<1.

(a) To show that Corr(X,Y)=0, we need to calculate the covariance between X and Y and divide it by the product of their standard deviations.

Cov(X,Y) = E[XY] - E[X]E[Y]

To calculate E[XY], we integrate the joint density function over the region where 2+y^2<1:

E[XY] = ∫∫ xy fx,y(x,y) dxdy
      = ∫∫ xy (1/π) dxdy   (since (X,Y) is a uniform random vector on the disc)
      = 0   (due to symmetry of the disc around the origin)

Similarly, E[X] and E[Y] can be calculated as follows:

E[X] = ∫∫ x fx,y(x,y) dxdy
      = ∫∫ x (1/π) dxdy
      = 0

E[Y] = ∫∫ y fx,y(x,y) dxdy
      = ∫∫ y (1/π) dxdy
      = 0

Therefore, Cov(X,Y) = E[XY] - E[X]E[Y] = 0, and so Corr(X,Y) = Cov(X,Y) / (sd(X) * sd(Y)) = 0.

(b) X and Y are not independent. To see why, consider the following:

P(X > 0, Y > 0) = Area of the quarter-disc in the first quadrant / Area of the full disc
                = (1/4) / π
                ≠ P(X > 0) * P(Y > 0) = (1/2) * (1/2) = 1/4

Therefore, we have shown that P(X > 0, Y > 0) ≠ P(X > 0) * P(Y > 0), which means X and Y are not independent. Another way to see this is to note that if X is known, then Y is restricted to the interval (-√(1-x^2), √(1-x^2)) due to the constraint 2+y^2<1.


(a) To show that Corr(X, Y) = 0, we need to find the covariance and the standard deviations of X and Y, then use the correlation formula:

Corr(X, Y) = Cov(X, Y) / (σX * σY)

Cov(X, Y) = E(XY) - E(X)E(Y)

Since (X, Y) and (-X, Y) have the same distribution, E(X) = E(-X) = 0, and E(XY) = E(-X*Y) = 0. Therefore,

Cov(X, Y) = E(XY) - E(X)E(Y) = 0 - 0 * 0 = 0.

Now, we know that Cov(X, Y) = 0. Since σX and σY are non-zero (given that the random vector is on the disc with x^2 + y^2 < 1), we can conclude:

Corr(X, Y) = 0 / (σX * σY) = 0.

(b) For X and Y to be independent, their joint density function fX,Y(x, y) should be the product of their marginal density functions fX(x) and fY(y). The fact that Corr(X, Y) = 0 doesn't necessarily imply independence.

To determine independence, we would need to find the marginal density functions of X and Y, then check if fX,Y(x, y) = fX(x) * fY(y) for all x and y values in the domain. If this equality holds, then X and Y are independent. If not, they are dependent.

In this case, we don't have enough information to determine the marginal density functions, so we cannot definitively conclude whether X and Y are independent.

The equilibrium price is $0 and the equilibrium quantity is 5 units.

To find the equilibrium price and quantity, we need to set the quantity demanded equal to the quantity supplied and solve for the equilibrium values.

Setting Q_d = Q_s, we can equate the equations for demand and supply:

-2Q - 2Q_d = -5 + 3Q_s

Since we know that Q_d = Q_s, we can substitute Q_s for Q_d:

-2Q - 2Q_s = -5 + 3Q_s

Now, let's solve for Q_s:

-2Q - 2Q_s = -5 + 3Q_s

Combine like terms:

-2Q - 2Q_s = 3Q_s - 5

Add 2Q_s to both sides:

-2Q = 5Q_s - 5

Add 2Q to both sides:

5Q_s - 2Q = 5

Factor out Q_s:

Q_s(5 - 2) = 5

Q_s(3) = 5

Q_s = 5/3

Now that we have the value for Q_s, we can substitute it back into either the demand or supply equation to find the equilibrium price. Let's use the supply equation:

P = -5 + 3Q_s

P = -5 + 3(5/3)

P = -5 + 5

P = 0

Therefore, the equilibrium price is $0 and the equilibrium quantity is 5 units.

You would need a sample size of 53 to estimate the population mean with an error of less than 5 and a 99% confidence level, given a population standard deviation of 13.6.

To estimate the population mean with an error of less than 5 and 99% confidence, you need to determine the required sample size using the given population standard deviation (σ = 13.6) and the desired margin of error (E = 5).

Step 1: Identify the confidence level (99%)
The confidence level indicates the probability that the true population mean lies within the margin of error. A 99% confidence level corresponds to a z-score (z) of 2.576, found in standard z-score tables or through software.

Step 2: Calculate the required sample size
The formula for determining the required sample size (n) when estimating the population mean with a specific margin of error and confidence level is:

n = (z^2 × σ^2) / E^2

Plugging in the values we have:

n = (2.576^2 × 13.6^2) / 5^2
n ≈ (6.635776 × 184.96) / 25
n ≈ 1304.756736 / 25
n ≈ 52.19

Step 3: Round up the result
Since you cannot have a fraction of a sample, round up the result to the nearest whole number. In this case, the required sample size is 53.

In conclusion, you would need a sample size of 53 to estimate the population mean with an error of less than 5 and a 99% confidence level, given a population standard deviation of 13.6.

The statement cannot be assumed to be true based solely on a survey of 1455 people.

While the survey results indicate that 53% of the surveyed population works a full-time job, it is not sufficient evidence to make assumptions about the entire U.S. population. A survey sample size of 1455 people may not accurately represent the diversity and demographics of the entire U.S. population, which consists of millions of individuals.

To make a valid assumption about the entire U.S. population, a more comprehensive and representative survey or data collection method would be required. This could involve surveying a much larger and more diverse sample size or gathering data from reliable sources such as government statistics or labor market reports.

Making assumptions about the entire population based on a small survey sample can lead to inaccurate conclusions and generalizations. The U.S. population is complex and dynamic, with variations in employment patterns, demographics, and other factors that cannot be fully captured by a limited survey sample.

Therefore, while the survey results provide insights into the surveyed population, it is not appropriate to assume that the same percentage of the entire U.S. population works a full-time job based solely on this survey.

Step-by-step explanation:

Using Leibniz's notation for the chain rule  \(\frac{dy}{dx}\)= 540x⁸.

To find ​ \(\frac{dy}{dx}\) using Leibniz's notation for the chain rule, we have:

y=f(u)=5u⁴+2

u=g(x)=3x³u

Let's start by finding \(\frac{dy}{du}\) and \(\frac{du}{dx}\) individually:

1. \(\frac{dy}{du}\):

To find \(\frac{dy}{du}\)​, we differentiate y with respect to u while treating uas the independent variable:

\(\frac{du}{dy}\) ​=d/du​(5u⁴+2) = 20u³

2. \(\frac{du}{dx}\) :

To find \(\frac{du}{dx}\)​ , we differentiate u with respect to x:

\(\frac{du}{dx}\)​​​ = d/dx​(3x³)=9x²

Now, we can apply the chain rule by multiplying  \(\frac{dy}{du}\) and  \(\frac{du}{dx}\) to find  \(\frac{dy}{dx}\)

\(\frac{dy}{dx}\) = \(\frac{dy}{du}\) * \(\frac{du}{dx}\) = (20 u³)* (9x²)

Substituting u=3x³:

\(\frac{dy}{dx}\) = (20(3x³)³)⋅(9x²)

Simplifying:

\(\frac{dy}{dx}\) = 540 x⁸

Therefore, \(\frac{dy}{dx}\)=540x⁸ using Leibniz's notation for the chain rule.
