A is correct Answer. with the point of the compass on A.dreaw an arc that intersects both sides of the angle at B and C.

Step 3 is unnecessary (the statement is already given, plus you haven't proven the triangle is isosceles anyway).

After, omit step 5 and jump straight to 6.

After this, step 6 is the statement that used to be step 5, which is true by CPCTC.

Then, you can prove the required statement by definition from this.

Answer:

\(\huge\boxed{\tt{x = 11 , y = 1}}\)

Step-by-step explanation:

x + y = 12 -------------------------(1)

2x + 5y = 27 --------------------(2)

Multiply (1) by 2

2(x+y) = 12 * 2

2x + 2y = 24 --------------------(3)

Subtract (3) from (2)

2x + 5y - ( 2x + 2y ) = 27 - 24

2x + 5y - 2x - 2y = 3

5y - 2y = 3

3y = 3

Divide 3 to both sides

y = 1

Put y = 1 in (1)

x + 1 = 12

x = 12 - 1

x = 11

So,

x = 11 , y = 1

The surface area of the sphere is about 50.27 square feet.

The formula for the surface area of a sphere is:

Surface area = 4πr²

The circumference of the sphere as C = 4r ft.

The radius of the sphere as follows:

C = 2πr

4r = 2πr

r = 2 ft

The radius of the sphere can use the formula for surface area to find the answer:

Surface area = 4πr²

Surface area = 4π(2²)

Surface area ≈ 50.27 square feet

Rounding the answer to the nearest hundredth, we get:

Area of fabric needed to cover the lampshade is 768 \(cm^2\)

What is Fabric?

Fabric can be either a cloth made by weaving or knitting, or it can be the framework of a construction. Some individuals use twisting, felting, or braiding to create fabrics. When I remark that termites are "gradually eating away at the fabric of the building," I'm referring to either the floor or the walls.

The phrase may also be used to refer to the fundamental framework or organization of society. For instance, "the fabric of society" refers to its fundamental structure, which includes all of its practices and beliefs.

I'm referring to the body of the car when I remark, "I heard clanking noises in the fabric of the car." This phrase can also be used to describe the body of an aircraft.

Length= 16 cm

Breath= 12 cm

Area= 4(16*12)  \(cm^2\)

Area=768 \(cm^2\)

Hence, Fabric needed is 768 \(cm^2\)

The probability of A and B is the probability of the intersection (AnB) of events A and B which is zero.

A die is a cube with six faces, labeled from 1 to 6. The elementary events are the six possible outcomes of the die roll, which are:

E1 = {1}, E2 = {2}, E3 = {3}, E4 = {4}, E5 = {5} and E6 = {6}.

The probability of the elementary events is the same for all outcomes and is given by:

P(E1) = P(E2) = P(E3) = P(E4) = P(E5) = P(E6) = 1/6

The event A that the outcome is greater than 3 can be written as A = {4, 5, 6}. The probability of A is:

P(A) = P(E4) + P(E5) + P(E6) = 1/6 + 1/6 + 1/6 = 1/2

The event B that the outcome is odd can be written as B = {1, 3, 5}. The probability of B is:

P(B) = P(E1) + P(E3) + P(E5) = 1/6 + 1/6 + 1/6 = 1/2

The probability of the union (AUB) of events A and B is:

P(AUB) = P(A) + P(B) - P(AnB) = 1/2 + 1/2 - P(AnB)

The probability of the intersection (AnB) of events A and B is zero since there is no outcome that is both greater than 3 and odd. Thus:

P(AnB) = 0

P(AUB) = 1/2 + 1/2 - 0 = 1

The probability of A is 1/2 and the probability of B is 1/2.

The probability of A and B is the probability of the intersection (AnB) of events A and B which is zero.

When a 99% confidence interval for the mean of a population is computed from a random sample, we can conclude that there is a high degree of certainty that the true population mean falls within this range. This information is useful in making informed decisions and drawing conclusions about the population.

A 99% confidence interval is a range of values within which the true population mean is likely to fall with 99% confidence. When a 99% confidence interval for the mean of a population is computed from a random sample, we can conclude that there is a high degree of certainty that the true population mean falls within this range.
For instance, let's assume that a random sample of a population is taken, and the 99% confidence interval for the mean is found to be (50, 70). This means that we are 99% confident that the true population mean falls within this range. Therefore, we can conclude that the population mean is most likely to be within this range with a high degree of certainty.
It is important to note that a 99% confidence interval is wider than a 95% confidence interval, which means that the level of confidence in the estimate is higher. The wider interval allows for a greater degree of uncertainty and variation in the data, which means that the true population mean is more likely to be captured within the interval.
In summary, when a 99% confidence interval for the mean of a population is computed from a random sample, we can conclude that there is a high degree of certainty that the true population mean falls within this range. This information is useful in making informed decisions and drawing conclusions about the population.

The annual appreciation of the coin from 1968 to 2019 was 6.7%. Hence the coin appreciated at a rate of 6.7% per year from 1968 to 2019.

In 2019, a coin was sold at auction for $4,120,500. The coin had a face value of $20 when it was first issued in 1786. The coin had been previously sold for $395,000 in 1968. At what price did the coin appreciate annually from 1968 to 2019? Solution:We can start this problem by using the compound interest formula which is given as follows;A = P (1+r/n)^(nt)Where:A is the future value of the investment;P is the principal investment;r is the annual interest rate;n is the number of times that interest is compounded per year;t is the number of years the money is invested.To solve the problem we will consider the following;We will use the initial price of the coin which was sold in 1968 which is $395,000 as the principal investment, PWe will use the price of the coin sold at auction in 2019 which is $4,120,500 as the future value of the investment, AWe will use the number of years between 1968 and 2019 which is 51 years as t.The interest rate is not given, but we can solve for it by substituting the known values into the formula as shown below;A = P (1+r/n)^(nt)=> 4,120,500 = 395,000 (1+r/1)^(1 x 51)=> (1+r) = (4,120,500/395,000)^(1/51)=> (1+r) = 1.067=> r = 1.067 - 1=> r = 0.067 = 6.7%Therefore the annual appreciation of the coin from 1968 to 2019 was 6.7%. Hence the coin appreciated at a rate of 6.7% per year from 1968 to 2019.

What is the uniform distribution?

Probability distributions with uniform distributions have outcomes that are all equitably likely. Results are discrete and have the same probability in a discrete uniform distribution. Results are continuous and infinite in a continuous uniform distribution. Data near the mean occur more frequently in a normal distribution.

Here, we have

Given: X1, X2,..., Xn is independent and identically distributed random variables having uniform distributions over (0,1).

a) Z = max{X₁, X₂....Xₙ}

Since Z is maximum so it is greater than X1, X2...Xn so cdf of Z will be

F(Z) = P(Z≤z) = P(X₁, X₂....Xₙ≤z) = P(X₁≤z, X₂≤z.....Xₙ≤z)

= P(X₁≤z)P(X₂≤z)....P(Xₙ≤z) = Fₓ(z)Fₓ(z).....Fₓ(z)

F(Z) = zⁿ

So pdf of Z is

F(z) = F'(z) = nzⁿ⁻¹

Expectation of Z is

F(Z) = \(\int\limits^0_1 {zf_Z(z)} \, dz\) = \(n\int\limits^0_1 {} \,\)zⁿdz

= n[zⁿ⁺¹/n+1]₀¹ = n/n+1

b) Let Y = min{X₁, X₂....Xₙ}

Since Y is the minimum so it is less than X1, X2...Xn so the cdf of Y will be

F(Y) = P(Y≤y) = 1 - P(Y>y) = 1- P(X₁, X₂....Xₙ≤z) = 1- P(X₁≤z, X₂≤z.....Xₙ>y)

= 1- P(X₁>y)P(X₂>y)....P(Xₙ>y) = 1- Fₓ(y)Fₓ(y).....Fₓ(y)

= 1 - [1-y]ⁿ

So pdf of Y is

F(y) = F'(y) = n[1-y]ⁿ⁻¹

The expectation of Y is

E(Y) = \(\int\limits^0_1 {yf_Y(y)} \, dy\) = ∫₀¹ yn(1-y)ⁿ⁻¹dy = 1/n+1

Hence, Maximum = n/n+1 and Minimum = 1/n+1

The general solution of the given homogeneous differential equation is:y = ±x√(Cx² + 2)

The given differential equation is: 2xyy' + (x² - y²) = 0

We have to find the general solution of the given homogeneous differential equation. To solve the above differential equation, we will use the substitution method.

Put y = vx and y' = v + xv'

Differentiating both sides w.r.t x: y' = v + xv' ⇒ v' = (y' - v)/x

Differentiating again w.r.t x: y'' = v' + xv'' + v' ⇒ y'' = (y'' - 2y'v + v² + xv')/x

Substituting these values in the given differential equation:

2x(v)(v + xv') + (x² - v²x²) = 0

2v + 2x²v' + x - v² = 0

2x²v' + 2v/x - v³/x = -1/x

We can write the above differential equation as:

2x²dv/dx + 2v/x = v³/x - 1/x

Separating the variables and integrating both sides:

∫dx/x = ∫[v/(v² - 2)]dv/x

⇒ ln |x| + ln |v² - 2| + C

⇒ ln |x(v² - 2)| = ln |Cx|

⇒ v² - 2 = Cx² (where C is a constant)

⇒ v = ±√(Cx² + 2)

Putting the value of v in y = vx, we get:

y = x√(Cx² + 2) and y = -x√(Cx² + 2)

For a 60% confidence interval, the number of cis that we expect to contain the true mean is of 60% of the total amount.

The interpretation of a x% confidence interval it is x% likely that the population parameter(mean/proportion/standard deviation) is between a and b, which are the bounds of the confidence interval.

The bounds a and b of the confidence interval are given by the estimate plus/minus the margin of error.

The interpretation also means that out of n samples, the percentage which are expected to contain the true mean is of x, hence the percentage for this problem is of 60%, as it is the confidence level.

The AOB 36V hoverboard has a higher speed and is faster.

To determine which hoverboard is faster, we need to compare their speeds. Speed is defined as the distance traveled per unit of time. In this case, we are given the distances traveled by each hoverboard in a specific amount of time.

The Jetson Sphere hoverboard travels 10 feet in 1/2 second, while the AOB 36V hoverboard travels 8 feet in 1/3 of a second.

To compare their speeds, we can calculate the speed for each hoverboard by dividing the distance traveled by the time taken.

For the Jetson Sphere hoverboard:

Speed = Distance / Time = 10 feet / (1/2 second) = 10 feet * 2 = 20 feet per second

For the AOB 36V hoverboard:

Speed = Distance / Time = 8 feet / (1/3 second) = 8 feet * 3 = 24 feet per second

Comparing the speeds, we can see that the AOB 36V hoverboard has a speed of 24 feet per second, while the Jetson Sphere hoverboard has a speed of 20 feet per second. Therefore, the AOB 36V hoverboard is faster.

We know this because the AOB 36V hoverboard covers a greater distance in the same amount of time compared to the Jetson Sphere hoverboard. It travels 24 feet in 1 second, while the Jetson Sphere hoverboard travels only 20 feet in the same time. Thus, the AOB 36V hoverboard has a higher speed and is faster.
