The dilation center is at C. The scale factor is 5/12. The value of x is 5/2.

What is dilation?

Meaning of Dilation in Math. Dilation is a transformation that allows you to resize an object. Dilation is a technique for making objects larger or smaller. This transformation yields an image that is identical to the original shape. However, there is a size difference in the shape.

Given that the length of the original rectangle is 12. The length of the new rectangle is 5.

The scale factor is the ratio of the dimension of the new rectangle to the dimension of the original rectangle = 5:12 = 5/12

The width of the new rectangle is the product of the original width by the scale factor = 5/12 × 6 = 5/2

The value of x is 5/2.

Answer:

x = 122°

Step-by-step explanation:

There is remote angle( non- adjecent angle) and their sum equal to the exterior angle .

Exterior angle is an angle formed from one side of the polygone and the extended side so

<A and <B are remot angle and <BCD is exterior angle .

And we write the equetion as

<A + <B = <BCD

58° + 64° = x°

122° = X°

so the exterior angle ( x ) measures 122° .

The test statistic for the population mean has a t-distribution with 9 degrees of freedom.

In probability and statistics, Student's t-distribution (or simply t-distribution) is any member of the family of continuous probability distributions for which the standard deviation is unknown when estimating the mean of a distributed population normally with small sample and population sizes.

The t-distribution is a symmetric bell-shaped distribution similar to the normal distribution. However, the t-distribution has heavier tails, which means it is more likely to produce values ​​that are far from the mean. This is useful for understanding the statistical behavior of ratios of certain types of random quantities, where variations in the denominator are magnified and outliers are produced when the denominator of the ratio is close to zero.

The t distribution is a statistical distribution that describes the normalized distance between a sample mean and the corresponding population mean.

This distribution (t-distribution) can be used when the data is approximately normally distributed. The degrees of freedom represent the number of independent observations in the data.

Finally, the test statistic for the population mean has a t-distribution with 9 degrees of freedom.

The length of one side of the octagon is 2.93 inches. The resulting octagon will have equal side lengths. We need to find the length of the side of the octagon.

Step 1: The square has a side length of 10 inches. So, the diagonal of the square will be 10√2 inches.

Step 2: The isosceles right triangles are congruent. Therefore, we can draw one of the triangles by cutting off one corner of the square.

The hypotenuse of the right triangle will be the side of the octagon and will be equal to the length of one side of the square minus the length of one of the legs of the right triangle. The length of each leg of the right triangle will be 10/√2.

Step 3: Using the Pythagorean theorem, we can find the hypotenuse of the right triangle. We can then subtract 10/√2 from the length of the side of the square to find the length of one side of the octagon.

The Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.a² + b² = c² Where a and b are the lengths of the legs of the right triangle and c is the length of the hypotenuse.

Using the theorem, we can find the length of the hypotenuse of the right triangle: (10/√2)² + (10/√2)² = c²100/2 + 100/2 = c²100 = c²c = √100 = 10 inches

Step 4: To find the length of one side of the octagon, we need to subtract 10/√2 from the length of the side of the square. The length of the side of the square is 10 inches. Therefore, the length of one side of the octagon will be:10 - 10/√2 = 10 - 7.07 ≈ 2.93 inches

Therefore, the length of one side of the octagon is 2.93 inches.

The results of a study are said to be replicable when researchers using new subjects come to the same conclusion. Replicability is important in research as it ensures the validity and reliability of the study findings.

The results of a study are said to be replicable when researchers using new subjects come to the same conclusion. Replicability is an important aspect of scientific research because it ensures that the findings are not simply a result of chance or bias. If a study cannot be replicated, it may be difficult to draw firm conclusions or generalize the findings to a broader population. However, it is important to note that replicability does not guarantee that the study is both statistically significant and meaningful.

A study may be replicable but still have limited practical or theoretical value. The p-value and significance level are important measures of statistical significance, but they do not necessarily indicate replicability. Finally, while statistics are knowable, parameters (such as population mean or variance) are typically unknown and must be estimated from the sample data.

The breadth of the rectangle is 3.4353 cm

What is rectangle?

A rectangle is a type of quadrilateral with parallel sides equal to each other and four equal 90-degree vertices. Because of this, it is also known as an equiangular quadrilateral. Because the opposite sides of a rectangle are equal and parallel, it can also be referred to as a parallelogram.

Area, A= 25.25 square cm

length, l = 7.35 cm

let b= breadth

Formula:

Area of a rectangle, A = l * b

                          25.25 = 7.35 * b

                            => b =  25.25 / 7.35   =  3.4353 cm

The vertex of the parabola is (2, 16). This means that the average of couches sold in Germany was the greatest in the year 2013, which is 2 years after 2011.

The equation y = -0.25(x - 2)² + 16 models the average of couches sold in Germany, where x is the number of years since 2011 and y is the number of couches sold. We can find the year when the average of couches sold in Germany was the greatest by finding the maximum value of the equation.

To find the maximum value, we can first rewrite the equation in vertex form: y = a(x - h)² + k, where (h, k) is the vertex of the parabola.

y = -0.25(x - 2)² + 16

y = -0.25(x² - 4x + 4) + 16

y = -0.25x² + x + 15

To find the vertex of the parabola, we can use the formula h = -b/2a and k = f(h), where f(h) is the value of y at the vertex.

h = -b/2a = -1/(2*(-0.25)) = 2

k = f(h) = -0.25(2)² + 2 + 15 = 16

Therefore, the vertex of the parabola is (2, 16). This means that the average of couches sold in Germany was the greatest in the year 2013, which is 2 years after 2011.

The probability that at least 70 out of 110 incoming freshmen will graduate in four years depends on additional information.

To calculate the probability that at least 70 out of 110 incoming freshmen will graduate within four years, we need additional information such as the distribution or mean of the graduation rate. The given probability of 0.654 represents the overall probability for an individual incoming freshman to graduate in four years, but it does not provide specific information about the group of 110 freshmen.

To determine the probability of at least 70 out of 110 freshmen graduating in four years, we would need to know the distribution of graduation rates or have additional information about the correlation or variability within the group. Without this information, it is not possible to provide a precise probability value. Further data or assumptions are necessary to calculate the desired probability.

============================================

Explanation:

Use the slope and given point to find the y intercept

y = mx+b

8 = (-2/3)*(1) + b

8 = -2/3 + b

8 + 2/3 = b

24/3 + 2/3 = b

26/3 = b

b = 26/3

The equation of the line is y = (-2/3)x + 26/3

To confirm this, plug in x = 1 and we should get y = 8, due to the point (1,8)

y = (-2/3)x + 26/3

y = (-2/3)*1 + 26/3

y = -2/3 + 26/3

y = (-2+26)/3

y = 24/3

y = 8

So that verifies we have the correct equation.

--------------

Next, go through each answer choice to see if the x coordinate of the point leads to the y coordinate.

If we try x = 7, then,

y = (-2/3)x + 26/3

y = (-2/3)(7) + 26/3

y = -14/3 + 26/3

y = (-14+26)/3

y = 12/3

y = 4

This shows that (7,4) is on the line. Choice A is the answer

That rules out choice B.

----------------

If we tried x = -5, then,

y = (-2/3)x + 26/3

y = (-2/3)(-5) + 26/3

y = 10/3 + 26/3

y = 36/3

y = 12

meaning that (-5,12) is on the line. That rules out choices C and D.

To convert an expression into standard form a + bi, you separate the real and imaginary parts and combine them using the appropriate operators.

To write an expression into standard form, a + bi form, you need to separate the real and imaginary components of the expression and combine them using the appropriate notation.

In a + bi form, 'a' represents the real part of the expression, and 'b' represents the imaginary part.

Let's say we have an expression in the form x + yi, where 'x' is the real part and 'y' is the imaginary part.

To convert this expression into standard form, you need to perform the following steps:

Separate the real and imaginary parts of the expression.

Write the real part first, followed by the imaginary part with 'i'.

Combine the real and imaginary parts using the appropriate operators (+ or -).

Let's take an example to illustrate this process:

Suppose we have the expression 3 + 2i.

Here, '3' is the real part, and '2' is the imaginary part.

To convert it into standard form, we write it as 3 + 2i.

Similarly, if we have the expression -5 - 4i, where '-5' is the real part and '-4' is the imaginary part, we write it as -5 - 4i.

In both cases, the expressions are in standard form, a + bi.
