Answer:

C

Step-by-step explanation:

6x^2 + 2x - 8

Multiply the (6) to the -(8) to get x^2 by itself.

x^2 + 2x  - 48

Solve -

(x-6)(x+8) = x^2 + 2x  - 48

However, you must divide out the (6) you multiplied.

(x-6/6) =

(x-1)

(x+8/6) =

(3x + 4)

Therefore, 2(3x + 4)(x-1) is your answer.

EDIT - At the beginning of the equation it is possible to divide (2) out of the equation, this is where the (2) at the end comes from.

Answer:

Un número decimal exacto es algo de la forma:

3.27

Para reescribir este número como una fracción, podemos ver que tiene dos dígitos luego del punto.

Entonces podemos multiplicar y dividir por 100 (misma cantidad de ceros que dígitos luego del punto decimal)

así obtenemos:

3.27*(100)/(100) = 327/100

Entonces la fracción 327/100 genera un decimal exacto.

Así, encontrar 10 fracciones es trivial, 10 ejemplos son:

7/10 = 0.7

314/100 = 3.14

27/10 = 2.7

27/100 = 0.27

2/10 = 0.2

25/100 = 0.25

31/10 = 3.1

12/10 = 6/5 = 1.2

131/10 = 13.1

142/100 = 1.42

Ahora, un decimal inexacto puro es algo de la forma:

3.33...

donde el 3 se repite infinitamente.

Tratemos de reescribir este número como una fracción:

primero debemos ver la cantidad de dígitos que se repiten, en este caso es uno solo, el 3, entonces multiplicamos por 10:

3.33*10 = 33.33...

Ahora, podemos restar el numero original:

33.333... - 3.333... = 30

Entonces tenemos que:

3.33*9 = 30

3.33 = 30/9

La fracción:

30/9 nos da in decimal inexacto puro.

Ahora que sabemos construirlas, 10 ejemplos pueden ser:

30/9 = 3.33....

1/3 = 0.33...

40/9 = 4.44...

50/9 = 5.55...

60/9 = 6.66...

70/9 = 7.77...

20/9 = 2.22...

55/9 = 6.11...

544/99 = 5.5959...

10/9 = 1.11...

Finalmente, un periódico mixto es algo de la forma:

1.2343434...

Es decir, el 34 se repite infinitamente, pero también tenemos un 2 luego del punto decimal, por lo que este número no es puramente periódico.

Para construirlos, podemos tomar una fracción exacta, como

1.1 y una periódica, como 1.11...

Si las sumamos, obtenemos:

1.1 + 1.11... = 2.211...

donde el uno se repetirá infinitamente.

Así, simplemente sumando las fracciones del primer caso con las del segundo, obtendremos decimales periódicos mixtos, por ejemplo:

7/10 + 55/9 = 613/90 = 0.7 +  6.11... = 6.8111....

7/10 +  10/9 = 163/90 = 0.7 + 1.11... = 1.811....

31/10 + 10/9 = 379/90 = 3.1 + 1.11... = 4.2111...

31/10 + 20/9 = 479/90 = 3.1 + 2.22... = 5.322...

31/10 + 30/9 = 579/90 = 3.1 + 3.33... = 6.4333...

27/10 + 20/9 =  443/90 = 2.7 + 2.22... = 4.922...

37/10 + 20/9 =  533/90 = 3.7 + 2.22... = 5.922...

4/10 +  10/9 = 136/90 = 0.4 + 1.11... = 1.511....

3/100 + 10/9 = 1027/900 = 0.03 + 1.11... = 1.14111...

4/10 +  20/9 = 236/90 = 0.4 + 2.22... = 2.622....

The derivative of the given integral with respect to x is 2x * sin(x⁶) - 1.

What is integration?

Integration is a mathematical operation that is the reverse of differentiation. Integration involves finding an antiderivative or indefinite integral of a function.

To solve this problem, we need to use the fundamental theorem of calculus and the chain rule.

Let's start by applying the fundamental theorem of calculus, which states that if F(x) is the antiderivative of f(x), then the integral of f(x) from a to x is equal to F(x) - F(a). In other words:

∫[a,x] f(t) dt = F(x) - F(a)

In this case, we have:

F(x) = ∫[0,x²] sin(t³) dt

So, applying the fundamental theorem of calculus, we get:

d/dx [∫[0,x²] sin(t³) dt] = d/dx [F(x) - F(0)]

Now, we need to apply the chain rule to find d/dx [F(x)]. Let's define a new function g(u) = ∫[0,u] sin(t³) dt. Then, we have:

F(x) = g(x²)

Using the chain rule, we get:

d/dx [F(x)] = d/dx [g(x²)] = g'(x²) * d/dx [x²] = 2x * g'(x²)

Substituting this back into the previous equation, we get:

d/dx [∫[0,x²] sin(t³) dt] = 2x * g'(x²) - F'(0)

To find g'(u), we can use the fundamental theorem of calculus again:

g'(u) = d/du [∫[0,u] sin(t³) dt] = sin(u³)

Substituting this back into the previous equation, we get:

d/dx [∫[0,x²] sin(t³) dt] = 2x * sin(x⁶) - cos(0) = 2x * sin(x⁶) - 1

Therefore, the derivative of the given integral with respect to x is 2x * sin(x⁶) - 1.

The length of the interior diagonal of a rectangular prism with a width of 60cm, length of 80cm, and height of 100cm is approximately 139.42cm.

To calculate the length of the interior diagonal, we can use the Pythagorean theorem. The Pythagorean theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides. In this case, the three sides of the right-angled triangle are the width, length, and height of the rectangular prism.

Using the Pythagorean theorem, we can calculate the length of the interior diagonal as follows:

Diagonal² = Width² + Length² + Height²

Diagonal² = 60² + 80² + 100²

Diagonal² = 3600 + 6400 + 10000

Diagonal² = 20000

Diagonal ≈ √20000

Diagonal ≈ 141.42 cm

Therefore, the length of the interior diagonal of the rectangular prism is approximately 139.42cm.

The bottom left corner is a right angle

To determine the 90% confidence interval for the mean repair cost for the TVs, we can use the formula:

Confidence Interval = Sample Mean ± (Critical Value * Standard Error)

Where:

Sample Mean = $91.78

Standard Deviation = $23.13

Sample Size = 44

Critical Value (z-value) for a 90% confidence level = 1.645 (obtained from a standard normal distribution table)

Standard Error = Standard Deviation / (\(\sqrt{Sample Size}\))

Standard Error = $23.13 / \(\sqrt{44}\)= $23.13 / 6.633 = $3.49 (rounded to two decimal places)

Confidence Interval = $91.78 ± (1.645 * $3.49)

Upper Bound = $91.78 + (1.645 * $3.49) = $91.78 + $5.74 = $97.52 (rounded to two decimal places)

Lower Bound = $91.78 - (1.645 * $3.49) = $91.78 - $5.74 = $86.04 (rounded to two decimal places)

Therefore, the 90% confidence interval for the mean repair cost for the TVs is approximately $86.04 to $97.52.

In this case, we are given the regression equation y = 30 + 8x, the sum of squared errors (SSE) as 980, and the total sum of squares (SS_Total) as 1,400. Our goal is to find the correlation coefficient.

To find the correlation coefficient (r), we need to first calculate the coefficient of determination (R^2). R^2 is the proportion of the total variation in the dependent variable (y) explained by the independent variable (x) and can be found using the formula:

R^2 = 1 - (SSE / SS_Total)

Plugging in the values given:

R^2 = 1 - (980 / 1,400) = 1 - 0.7 = 0.3

Now that we have the coefficient of determination (R^2 = 0.3), we can find the correlation coefficient (r) by taking the square root of R^2 and determining the appropriate sign. The sign of the correlation coefficient will be the same as the sign of the slope (8) in the regression equation. Since the slope is positive, the correlation coefficient will also be positive.

r = ±√(R^2) = ±√(0.3) ≈ ±0.5477

Since the slope is positive, we choose the positive value for r:

r ≈ 0.5477

Therefore, the correlation coefficient for this regression equation is approximately 0.5477.

The correct answer is D. Normal, with a center at mu and a standard deviation of sigma/√n. The correct answer is A. The standard deviation will be smaller, but the center will remain the same.

a) When the sample is randomly selected from a population that has a Normal distribution, the sampling distribution of the sample mean will also have a roughly Normal shape.

The population mean (mu) will serve as the sampling distribution's center, and the sampling distribution's standard deviation (sometimes referred to as the standard error) will be equal to the population standard deviation (sigma) divided by the square root of the sample size (n). The correct answer is D.

b) The sampling distribution's standard deviation (or standard error) diminishes as the sample size increases. This is so that the population mean can be estimated with more accuracy, which reduces the variability in the sample means. As long as the population as a whole doesn't change, the sample distribution's center (the population mean) will, however, stay the same. The correct answer is A.

The measure of each of the acute angles of the right triangle is 32° and 58°.

A right triangle is a kind of triangle which has a right angle (90°) and two acute angles (less than 90°).

Let x = measure of one of the acute angles

If the measure of one acute angle of a right triangle is 6 less than twice the measure of the other acute angle, then

measure of the other acute angle = 2x - 6

The sum of all the angles of any triangle is equal to 180°. Hence,

90° + x + 2x - 6 = 180°

Solve for the value of x.

3x = 96

x = 32

Solve for the measure of the other acute angle.

If testing shows that there is less than a 5% chance the results were random, the study is considered statistically significant.

In statistical hypothesis testing, researchers often set a significance level, denoted as α (alpha), which is typically 0.05 or 5%. This significance level represents the threshold below which the researchers consider the results to be statistically significant. If the p-value, which is a measure of the evidence against the null hypothesis, is less than the chosen significance level, it indicates that the results are unlikely to have occurred by chance alone.

When testing shows that there is less than a 5% chance (or any chosen significance level) that the results were random, the study is considered statistically significant. This means that the observed data provides evidence to reject the null hypothesis in favor of the alternative hypothesis. The results are deemed significant because the probability of obtaining such extreme or more extreme results under the assumption of randomness is very low.

Statistical significance is an important criterion in research as it helps researchers draw valid conclusions and make inferences from their data. However, it is essential to note that statistical significance does not imply practical significance or the magnitude of the effect observed. Additional considerations, such as effect size and contextual relevance, are necessary to fully interpret the implications of a statistically significant result in practical terms.
