Answer:

Domain of n^-1(x) = {x ∈ R | x ≤ -2 or x ≥ 2}

Step-by-step explanation:

We begin by finding the inverse of the function n(x).

n(x) = x + 1/x

To find the inverse, we replace n(x) with y:

y = x + 1/x

Then we solve for x in terms of y:

yx = x^2 + 1

x^2 - yx + 1 = 0

Using the quadratic formula, we get:

x = (y ± √(y^2 - 4))/2

Therefore, the inverse function of n(x) is:

n^-1(x) = (x ± √(x^2 - 4))/2

The domain of n^-1(x) is all values of x that make the expression under the square root non-negative:

x^2 - 4 ≥ 0

(x - 2)(x + 2) ≥ 0

The expression is non-negative when x ≤ -2 or x ≥ 2. Therefore, the domain of n^-1(x) is:

Domain of n^-1(x) = {x ∈ R | x ≤ -2 or x ≥ 2}

When two variables vary along with each other but the data points are loosely scattered around the line of best fit, the correlation is weak correlation.

We need to find the type of correlation when two variables vary along with each other but the data points are loosely scattered around the line of best fit.

A scatter plot helps find the relationship between two variables. This relationship is referred to as a correlation. Based on the correlation, scatter plots can be classified as follows.

A weak positive correlation indicates that, although both variables tend to go up in response to one another, the relationship is not very strong. A strong negative correlation, on the other hand, indicates a strong connection between the two variables, but that one goes up whenever the other one goes down.

Therefore, when two variables vary along with each other but the data points are loosely scattered around the line of best fit, the correlation is weak correlation.

when you flatten a spherical meatball into a hamburger, you increase its surface area while keeping the volume constant.

A sphere is a three-dimensional shape that has a curved surface. When you flatten a spherical meatball into a hamburger, you are essentially reshaping it into a flat, disk-like form. By doing so, you increase the area that is in contact with the cooking surface, such as a pan or grill. This larger surface area allows for more even cooking and browning.

However, the total amount of meat remains the same when you flatten the meatball. The volume of an object refers to the amount of space it occupies, and since the meatball is being flattened without adding or removing any meat, the volume remains constant. In other words, the flattened hamburger will have a larger surface area but the same amount of meat as the original spherical meatball.

So, when you flatten a spherical meatball into a hamburger, you increase its surface area while keeping the volume constant.

When you flatten a spherical meatball into a hamburger, you decrease its volume and increase its surface area.

When a spherical meatball is flattened into a hamburger, its shape changes from a sphere to a flat disk. This transformation affects both the volume and surface area of the meatball.

The volume of a sphere is given by the formula V = (4/3)πr^3, where r is the radius of the sphere. The surface area of a sphere is given by the formula A = 4πr^2.

On the other hand, the volume of a disk (or a circle) is given by the formula V = πr^2, where r is the radius of the disk. The surface area of a disk is given by the formula A = 2πr.

When the meatball is flattened, its radius decreases, resulting in a smaller volume. The volume of the flattened meatball is less than the volume of the original spherical meatball.

However, the surface area of the flattened meatball increases. The surface area of the flattened meatball is greater than the surface area of the original spherical meatball.

Answer:

x = 31.3°

Step-by-step explanation:

\(cos (A) = \frac{b^{2} + c^{2} - a^{2} }{2bc} \)

here a = 8 ,  b = 11 , c = 15

using the formula:

cos(x) = (11² + 15² - 8²) / ( 2 * 11 * 15)

cos(x) = \(\frac{47}{55} \)

x = \(cos^{-1} (\frac{47}{55} )\)

False. The number in front of the "E" in E notation must always contain a decimal point to accurately represent the value.

b. False. When using E notation (also known as scientific notation), the number in front of the "E" must contain a decimal point.

E notation is a way to express very large or very small numbers in a compact form. It consists of two parts: the significand (or mantissa) and the exponent. The significand represents the main digits of the number, and the exponent indicates the power of 10 by which the significand should be multiplied.

It is crucial to include a decimal point in the significand to accurately represent the number in E notation. Omitting the decimal point can lead to a misunderstanding or incorrect interpretation of the value.

Answer:

2.537 x 10¹⁵ miles

Step-by-step explanation:

We are given the following:

1 light year = 5.9 x 10¹² miles

Distance of the star = 4.3 x 10² light years

To get this we just convert the distance of the star in light years into miles.

We cancel out the light years and then we are left with:

In dealing with scientific notation, when we multiply them we can treat the coefficients and exponents of 10 separately.

Coefficients:

4.3 x 5.9 = 25.37

Exponents of 10:

10² x 10¹² = 10⁽²⁺¹²⁾=10¹⁴

Then we combine them again to form a scientific notation:

25.37 x 10¹⁴

But since the standard in writing a scientific notation, the coefficient needs to be a number from 1-9, we need to move the decimal. When we move the decimal to the right or left, we change the exponent of the power of 10. Since we will move it once to the left, we add 1.

The answer will then be:

2.537 x 10¹⁵ miles

To find the indefinite integral of the given expression, we can use the logarithmic rule of integration.

The integral of 1/(x^2 + 6) with respect to x can be expressed as:

∫(1/(x^2 + 6)) dx

To integrate this, we make use of the logarithmic rule:

∫(1/(x^2 + a^2)) dx = (1/a) * arctan(x/a) + C

In our case, a^2 = 6, so we have:

∫(1/(x^2 + 6)) dx = (1/√6) * arctan(x/√6) + C

Hence, the indefinite integral of the given expression is:

∫(1/(x^2 + 6)) dx = (1/√6) * arctan(x/√6) + C

where C represents the constant of integration.

To estimate the mean BMI (m) in the population of American young women with a confidence interval of ±1 and 99% confidence, we can use the formula:

n = (Z * σ / E)^2

Where:

n = required sample size

Z = Z-value corresponding to the desired confidence level (99% confidence level corresponds to Z = 2.576)

σ = standard deviation of the population (given as 7.5)

E = margin of error (±1)

Plugging in the values, we have:

n = (2.576 * 7.5 / 1)^2

n = (19.314 / 1)^2

n = 372.36

Rounding up to the nearest whole number, we need a sample size of approximately 373 to estimate the mean BMI in the population with a 99% confidence level and a margin of error of ±1.

⇒ y = - 2x - 6

What is Equation of line?

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

The point on the line are (-1, -4).

And, The gradient is,

⇒ m = - 2

Now,

Since, The equation of line passes through the point (- 1, - 4).

And, The gradient is,

⇒ m = - 2

Thus, The equation of line with slope - 2 is,

⇒ y - (-4) = - 2 (x - (-1))

⇒ y + 4 = - 2 (x + 1)

⇒ y + 4 = - 2x - 2

⇒ y = - 2x - 2 - 4

⇒ y = - 2x - 6

a. Null hypothesis: The success rate for ART at this clinic is equal to the success rate reported by the CDC. Alternative hypothesis: The success rate for ART at this clinic is higher than the success rate reported by the CDC.

b. The histogram shows the distribution of simulated proportions in 1,000 simulations under the null hypothesis. The proportion in the observed sample is indicated by the red line.

c. The consumer group's news headline may not be appropriate since there is strong evidence to support the company's claim.

a. Null hypothesis: The null hypothesis states that there is no significant difference in success rates between the fertility clinic and the CDC. H0: P = 0.488. Alternative hypothesis: The alternative hypothesis states that there is a significant difference between the fertility clinic and the CDC. H1: P > 0.488, where P is the proportion of cases where live birth occurs in the 30 patients

b. The p-value is the probability of observing a result as extreme as or more extreme than what was observed, assuming the null hypothesis is true. The p-value can be estimated by finding the proportion of simulated proportions that are greater than or equal to the observed proportion.In this case, the observed proportion is 0.6, which is to the right of the center of the histogram.

The p-value is therefore the proportion of simulated proportions that are greater than or equal to 0.6. From the histogram, it appears that this proportion is less than 0.001, which means that the p-value is less than 0.001. Since the p-value is less than the significance level of 0.05, we reject the null hypothesis and conclude that there is strong evidence to support the company's claim.

c.  The hypothesis test showed that the success rate at this clinic is significantly higher than the success rate reported by the CDC. However, it is possible that the sample of 30 patients is not representative of all patients who receive ART at this clinic, or that the sample is biased in some way. Therefore, it may be appropriate for the consumer group to investigate further or to request more information from the clinic before making a definitive statement.
