What is the excluded value from the domain? (Image below). I got x = -3 but it says it is x = -6, -3. I've also uploaded my work.

Answer:

[tex]4y^{2}[/tex]

Step-by-step explanation:

A = Area

w = width

l = length

[tex]A=lw[/tex]

in this equation the area is [tex]32xy^{3}[/tex] and the length is [tex]8xy[/tex].

To find the equation we simply have to divide the area ([tex]32xy^{3}[/tex]) by the length ([tex]8xy[/tex]).

[tex]32xy^{3} =(8xy)w[/tex]

When dividing, it's important to remember two things:

Using these two rules, we divide the common bases (number by number, x by x, y by y):

[tex]\frac{32}{8}=4[/tex]

[tex]\frac{x}{x}=1[/tex]

[tex]\frac{y^{3} }{y}=y^{2}[/tex]

Multiplying all of them together, we find that the width is:

[tex]4y^{2}[/tex]

The statement “The relationship between the spring constant (k), the mass (m), and the period of oscillation (t) is given by the equation (19) this is not a linear equation, but it can be linearized using the same method used to linearize equation 10.” is true because equation 19 can indeed be linearized with the same method used to linearize equation 10.

Equation 10 is a non-linear equation and can be linearized by taking the natural logarithm of both sides. This will convert the equation into a linear form which can be used to calculate the parameters of the original equation.

Similarly, equation 19 can be linearized by taking the natural logarithm of both sides. The linearized form of equation 19 will also be useful in finding out the parameters of the original equation.

By linearizing the equations, it becomes easier to solve for the parameters of the equations. This is because linear equations are much simpler and can be solved using basic algebraic methods.

Linear equations can also be solved using matrix methods and can be used to solve for the parameters of the original equations more accurately.

Therefore, it is true that equation 19 can be linearized using the same method used to linearize equation 10. This will make it easier to solve for the parameters of the original equation.

The experimenter cannot control the probability of a Type I error, but they can control the level of significance they set, and that will determine the probability of making this type of error.

The probability of committing a Type I error is determined by the level of significance (α, alpha) that one chooses. This is because the level of significance is the probability of rejecting the null hypothesis when it is actually true. In other words, the level of significance is the probability of making a Type I error (falsely rejecting the null hypothesis). For example, if the level of significance is set to 0.05, then the probability of making a Type I error is 0.05. This can be expressed mathematically as: P(Type I Error) = α. Therefore, the experimenter cannot control the probability of a Type I error, but they can control the level of significance they set, and that will  the probability of making this type of error.

Answer:

true

Step-by-step explanation:

A unit rate is a price for one unit of anything. This is written as a ratio with a denominator of one.

The correct option is D, The probability that the Z-transform is greater than 2 in absolute value Pr (Z] > 2) is approximately 5%.

The Empirical rule states that 2 standard deviation from mean contains 95% data.

For,  Z follows standard normal distribution.

[tex]Z ~ Normal(\mu=0, \sigma=1)[/tex]

Then,

P( -2 ≤ Z≤ +2) = 0.95

Or

P(|Z| ≤ 2) = 0.95

And

P( |Z|>2) = 1 - P(|Z|≤2)

P(|Z|>2) = 1- 0.95

P(|Z|>2) = 0.05 = 5%

Probability is a mathematical concept that deals with the likelihood of events or outcomes. It is expressed as a number between 0 and 1, with 0 meaning no chance of an event occurring and 1 meaning that an event is certain to occur. In probability theory, random experiments are performed and the results are analyzed to determine the probability of specific outcomes.

For example, if you roll a dice, there are 6 possible outcomes and each outcome has a probability of 1/6. In statistics, probabilities are used to make predictions and to analyze data. The use of probabilities is essential in fields such as insurance, finance, and decision making as it provides a framework for making decisions based on uncertain information. Probability is an important tool for understanding and making decisions about the world around us.

It is not appropriate to assume that the sampling distribution of the sample mean is approximately normal when the sample size is small and the population distribution is skewed to the right or to the left. So, the options C and D are not appropriate. A and B are appropriate as the sample size is large and the population is normally distributed. E is also appropriate as the sample size is large.

The central limit theorem states that if we have a large enough sample size (typically n >= 30) from any population with a well-defined mean and finite variance, then the distribution of the sample mean approaches a normal distribution with mean equal to the population mean and variance equal to the population variance divided by the sample size.

However, if the population distribution is highly skewed, meaning it is not symmetric, then even a large sample size may not lead to a normal distribution of the sample mean.

In this case, it is not appropriate to assume that the sampling distribution of the sample mean is approximately normal. This is why options C and D are not appropriate as the sample size is large (10 and 75 respectively) but the population distribution is skewed to the right or to the left. On the other hand, options A and B are appropriate as the sample size is large and the population is normally distributed. Option E is also appropriate as the sample size is large, regardless of the shape of the population distribution.

Cylindrical shells: finding volume by rotating region around y-axis by integrating thin cylindrical shell area with height dr and radius f(x) over an interval.

To find the volume generated by rotating a region about the y-axis using the method of cylindrical shells, you need to integrate the area of a thin cylindrical shell with height dr and radius f(x) (where f(x) is the equation of the boundary curve) over the interval of x.

The volume generated by rotating the region bounded by the given curves can be found using the following formula:

[tex]V=\pi \int\limits[a,b] {(f(x))^{2} } \, dr[/tex]

Here, a and b are the lower and upper limits of the interval, and f(x) is the equation of the boundary curve. The integration should be performed over the given interval to obtain the volume.

In essence, the method of cylindrical shells involves wrapping the region around the y-axis to form a series of cylindrical shells and finding the volume of each shell, then summing up all the volumes to get the final volume.

There exists a value of c in the interval [0,2] such that g(c) = 1, and that value is c = 1/2. (option c)

The mean value theorem states that for any continuous function over a closed interval, there exists a point at which the value of the function is equal to the average of the minimum and maximum values of the function. In this case, the interval is [0,2] and the function is g(x) = -3√x + 2.

To find the value of c, we need to find the average of the minimum and maximum values of g(x) in the interval [0,2]. The minimum value of g(x) in the interval is g(0) = 2, and the maximum value is g(2) = -3√2 + 2 = 0. The average of the minimum and maximum values is (0 + 2)/2 = 1. Hence, there exists a value of c in the interval [0,2] such that g(c) = 1, and that value is c = 1/2.

The area of each composite figure is 828.96 cm².

A 3D object's surface area is the entire area that all of its faces cover. For instance, the surface area of a cube is its surface area if we need to determine how much paint is needed to paint it. It is consistently expressed in square units.

Given:

Surface area = SA of Cone + SA of Hemisphere

Cone:

radius = 8 cm

slant height = 17 cm

So, SA of Cone = πrl

                          = 3.14 x 8 x 17

                          = 427.04 cm²

Hemisphere:

radius = 8 cm

So, SA of Hemisphere = 2πr²

                                     = 2 x 3.14 x 8 x 8

                                     = 401.92 cm²

The total area of the given 5 square rooms is (3×14²)+(2×17²). Therefore, option A is the correct answer.

The area of a thing is the amount of space it occupies in two dimensions. It is the measurement of the quantity of metric squares that completely cover the entire surface of an enclosed figure. The square unit, which is frequently expressed as square inches, sq.ft, etc., is the accepted unit of area.

Area is the entire amount of space occupied by a plain (2-D) surface or an object's form. The area of a planar figure is the area that its perimeter encloses. The quantity of unit triangles that cover a closed figure's surface is its area. Area is measured in units like mm in diameter and m2.

Given that, sides of three square rooms measure 14 feet each, and sides of two square rooms measure 17 feet each.

We know that, area of square =a², where a is the side of square

Now, area of a square room with side 14 feet

= 14² square feet

The area of 3 square room with sides 14 feet

= 3×14² square feet

The area of a square room with side 17 feet

= 17² square feet

The area of 2 square room with sides 17 feet

= 2×17² square feet
