The order of string lengths from the longest to the shortest is:

8.8 meters, 36 decimeters, 672 centimeters. So the correct option is : 2

To compare these lengths, we need to convert them to the same units.

8.8 meters is the longest length.

36 decimeters is equivalent to 3.6 meters.

672 centimeters is equivalent to 6.72 meters.

1 meter = 10 decimeters = 100 centimeters

Now converting ,

So, 8.8 meters = 88 decimeters = 880 centimeters

36 decimeters = 360 centimeters

Now we can see that the order from longest to shortest is:

8.8 meters = 880 centimeters

36 decimeters = 360 centimeters

The assumption that AXB is a bounded angle is false, as a result, if AXB is a circumscribed angle of circle C, then AXB and ACB are supplementary.

To complete the proof of the Circumscribed Angle Theorem, use the fact that an inscribed angle of a circle is equal to half of the central angle that intercepts the same arc.

Since angle ∠AXB is circumscribed by the circle, point X lies on the circumference of the circle. Therefore, angles ∠CXA and ∠CXB are inscribed angles that intercept the same arc AB.

By the Inscribed Angle Theorem:

∠CXA = ½∠CAB

∠CXB = ½∠CAB

Adding these two equations:

∠CXA + ∠CXB = ½∠CAB + ½∠CAB

∠CXA + ∠CXB = ∠CAB

Now, observe that angles ∠CAB and ∠ACB form a linear pair, since they are adjacent angles that together make a straight line. Therefore, they are supplementary, which means:

∠CAB + ∠ACB = 180°

Substituting ∠CAB with ∠CXA + ∠CXB:

∠CXA + ∠CXB + ∠ACB = 180°

Finally, ∠AXB and ∠CXB form a linear pair, since they are adjacent angles that together make a straight line. Therefore, they are supplementary, which means:

∠AXB + ∠CXB = 180°

Substituting ∠CXB with ∠CAB - ∠CXA:

∠AXB + ∠CAB - ∠CXA = 180°

Adding ∠CXA to both sides:

∠AXB + ∠CAB = ∠ACB + 180°

Substituting ∠AXB + ∠CAB with 180° (since they are adjacent angles that together make a straight line):

180° = ∠ACB + 180°

Simplifying:

∠ACB = 0°

This is a contradiction, since we know that ∠ACB is a non-zero angle. Therefore, our assumption that ∠AXB is a circumscribed angle must be false. Hence, we have proved that if ∠AXB is a circumscribed angle of circle C, then ∠AXB and ∠ACB are supplementary.

The probability that a student who did not complete the homework passed the test is 0.25.

Answer:

c.

Step-by-step explanation:

The original triangle has two sides with length 4x each, and the hypotenuse has length 3y.

After the enlargement, each of the sides with length 4x becomes 3y × 4x = 12xy, and the hypotenuse becomes 3y × 3y = 9y^2.

Therefore, the perimeter of the enlarged triangle is the sum of the lengths of its three sides:

12xy + 12xy + 9y^2 = 24xy + 9y^2 = 9y^2 + 24xy

So the answer is (C) 9y^2 + 24xy.

The explanation of how to convert a general form equation to a standard form equation is given below:

Let's first look at how to convert a general form equation to a standard form equation. Given a general form equation:

x^2 + y^2 + Dx + Ey + F = 0

Complete the square for both x and y:

a. Divide the coefficients D and E by 2, and square the results. Let's call these values Cx and Cy:

Cx = (D/2)^2

Cy = (E/2)^2

b. Add and subtract Cx and Cy on both sides of the equation:

x^2 + Dx + Cx + y^2 + Ey + Cy = -F + Cx + Cy

Rearrange the equation to form the standard form equation:

a. Group the x and y terms and rewrite as perfect squares:

(x + D/2)^2 + (y + E/2)^2 = -F + Cx + Cy

b. Now, compare this to the standard form equation:

(x - h)^2 + (y - k)^2 = r^2

c. Identify the values of h, k, and r:

h = -D/2

k = -E/2

r^2 = -F + Cx + Cy

Now let's see how to convert a standard form equation to a general form equation. Given a standard form equation:

(x - h)^2 + (y - k)^2 = r^2

Expand the squares:

(x^2 - 2hx + h^2) + (y^2 - 2ky + k^2) = r^2

Rearrange the equation to form the general form equation:

x^2 + y^2 - 2hx - 2ky + h^2 + k^2 - r^2 = 0

Compare this to the general form equation:

x^2 + y^2 + Dx + Ey + F = 0

Identify the values of D, E, and F:

D = -2h

E = -2k

F = h^2 + k^2 - r^2

Now you can convert equations between the general form and the standard form. If you're missing some variables in the general form equation, just treat them as zero and proceed with the same steps.

Angles VYX and ZVX are alternate interior angles and are congruent.

Length of XW = 13 * 54 / WV, Length of WV = 702 / XW.

XW/YZ = VZ/WV (by similarity of triangles WYX and VZX).

Congruency refers to the property of two geometric figures that have exactly the same size and shape, so that they can be superimposed on one another. In other words, if two geometric figures are congruent, then all corresponding sides and angles of the figures are equal in measure.

1. To find the length of XW, we can use the fact that VZ is parallel to WY to set up a proportion. Since VZ and WY are parallel, we know that angles VZW and WYX are alternate interior angles and are therefore congruent. Similarly, angles VYX and ZVX are alternate interior angles and are congruent. Thus, we have:

XW/YZ = VZ/WV (by similarity of triangles WYX and VZX)

XW/13 = 54/WV (substituting the given values)

We can solve for XW by multiplying both sides by 13:

XW = 13 * 54 / WV

2. To find the length of WV, we can use the same proportion we set up in part 1 and substitute the given values:

Copy code

XW/YZ = VZ/WV

XW/13 = 54/WV

We can solve for WV by multiplying both sides by 54 and then dividing both sides by XW:

As the sample size increases, the shape of the distribution approaches the normal distribution, and the spread of the sampling distribution increases. The correct answer is option D.

As the sample size increases, the shape of the sampling distribution of the sample proportion approaches the normal distribution, and the spread of the sampling distribution decreases. The mean of the sampling distribution is always equal to the true proportion of that population, regardless of the sample size.

This phenomenon is due to the Central Limit Theorem (CLT), which states that as the sample size increases, the sampling distribution of the sample proportion becomes increasingly normal in shape, even if the population distribution is not normal.

The spread of the distribution decreases because larger sample sizes lead to more precision in estimating the true proportion.

Moreover, the mean of the sampling distribution of the sample proportion is equal to the true proportion of the population, regardless of the sample size. This property is known as unbiasedness. As the sample size increases, the variance of the sampling distribution decreases, resulting in a more precise estimate of the true proportion.

In conclusion, the larger the sample size, the more accurately the sample proportion represents the true proportion of the population. This result is due to the combination of the CLT and the unbiasedness of the sample proportion as an estimator of the population proportion.

The probability that an athlete who tests negative actually did not take steroids is approximately 0.926 or 92.6%.

Let's assume that 100 athletes were tested that day. Of these, 10 are expected to have taken steroids, and 90 are expected to have not taken steroids.

Of the 10 athletes who took steroids, the test is accurate 95% of the time, so 9 of them are expected to test positive for steroids, and 1 is expected to test negative.

Of the 90 athletes who did not take steroids, the test is accurate 97% of the time, so 87 of them are expected to test negative for steroids, and 3 are expected to test positive.

Therefore, out of the 100 athletes tested, a total of 90 + 1 + 3 = 94 are expected to test negative for steroids.

Since we know that the test is accurate, the probability that an athlete who tests negative actually did not take steroids is:

(Probability that athlete did not take steroids and tested negative) / (Probability of testing negative)

= 87 / 94

= 0.9255 (rounded to four decimal places)

If the rectangular "flower-garden" has area of 30 m², then dimensions of garden to minimize the combined area of garden and borders is length is √15 m and width is √60 m.

Th area of the rectangular garden is 30m²,

So, rectangular garden area is expressed using the equation

⇒ 30 = L×W, where L is length and W is width.

So, We can express "L", in terms of W, by equation,

⇒ L = 30/W.

We need to minimize the "combined-area" of garden and it's borders.

The equation for the combined area is ⇒ A = (L + 1)(W + 2).

We minimize area by first expressing the function in terms of "W", and then differentiate the function for "combined-area" and then equate the derivative to 0.

The dimension which satisfies the equation optimizes the combined area.

⇒ A = (L+1)×(W+2)

⇒ A = (30/W + 1)×(W + 2)

⇒ A = 30 + W + 60/W + 2

⇒A = 32 + W + 60/W,

Differentiating the area with the width,

We get,

⇒ dA/dW = 1 − 60/W²

⇒ 0 = 1 − 60/W²

⇒ 1 = 60/W²

⇒ W² = 60, ⇒ W = √60.

Function f(x) = √6x

And g(x)= 1/ (x-6

Composition function fog is ,

fog(x) = f(g(x))

Domain of fog(x),

First, find the domain of g(x),

The denominator of g(x) cannot be equal to zero,

So we must exclude x = 6 from the domain of g(x).

The domain of g(x) is equal to ,

domain of g(x) = {x | x ≠ 6}

The range of g(x) is,

As x approaches 6 from the left, g(x) approaches negative infinity,

And as x approaches 6 from the right, g(x) approaches positive infinity.

Range of g(x) = (-∞, 0) U (0, ∞)

The rate at which the base of the triangle is changing when the altitude is 20 cm and the area is 120 cm^2 is 0 cm/s.

To solve this problem, we need to use the formula for the area of a triangle, which is:

A = (1/2)bh

Where A is the area, b is the base, and h is the altitude.

We know that the area is 120 cm^2 and the altitude is 20 cm. So we can plug in these values and solve for the base:

120 = (1/2)b(20)

240 = 20b

b = 12 cm

Now we need to differentiate both sides of the equation with respect to time (t):

dA/dt = (1/2)(db/dt)h

We are given the value of dh/dt (which represents the rate at which the altitude is changing) is 3 cm/s. We need to find db/dt (which represents the rate at which the base is changing).

Plugging in the values we know, we get:

dA/dt = (1/2)(db/dt)(20)

Solving for db/dt, we get:

db/dt = (2dA/dt)/h

Plugging in the values we know, we get:

db/dt = (2)(0)/20

db/dt = 0 cm/s
Since the area is constant (120 cm²) and the altitude is constant (20 cm), the base of the triangle is not changing. Therefore, the rate at which the base is changing is: 0 cm/s

In algebra, the definition of an equation, in its simplest form, is a mathematical statement that shows that two mathematical expressions are equal. For example, 3x + 5 = 14 is an equation where 3x + 5 and 14 are two expressions separated by the equation.

To test the hypothesis that stock betas are higher in bear markets, we use the following regression equation:

Ri = αi + βi(Rm) + εi

where,

Ri = return on ith stock

Rm = market return

αi = intercept (constant term) of the regression equation of the ith stock.

βi = slope of the market return of the ith stock (regression coefficient).

εi = error period of the ith stock

To test the hypothesis, we  include an additional variable in the regression equation that describes the effect of the market return when it is negative. This variable would be a dummy variable that takes the value  1 if the market return is negative and 0 otherwise. Let's call this variable D. So the modified regression equation would be:

Ri = αi + βi(Rm) + γiD + εi

where,

γi = the excess regression coefficient of the ith stock that describes the effect of the market return when it is negative

The coefficient γi measures the difference between the  beta value of a stock between a falling market and a non-falling market. If γi is significantly greater than 0, this supports the analyst's hypothesis that betas are higher in  down markets.
