The simplified expression of \(\sqrt[4]{567(x^9)(y^{11})}\) is \(3x^2y^2\sqrt[4]{7xy^3}\).

Given expression:

\(\sqrt[4]{567(x^9)(y^{11})}\).

We can simplify the expression using the property that says for any non-negative numbers a and b, and any integer n ≠ 0,

\((a\times b)^{n} = a^n \times {b^n}\)

Using this property, we can simplify the expression as follows:

\((567x^9y^{11})^{1/4} = (567)^{1/4} \times (x^9)^{1/4} \times (y^{11})^{1/4}\)

Now we need to simplify,

\((81\times 7)^{1/4}x^{9/4}y^{11/4}\\=(81)^{1/4}(7)^{1/4}(x^{\frac{8}{4}+\frac{1}{4})(y^{\frac{8}{4}+\frac{3}{4})\)

Also,

\({3^4}^{1/4}(7)^{1/4}(x^{2+\frac{1}{4}})(y^{2+\frac{3}{4}})\\=3^1 7^{1/4}x^2x^{1/4}y^2y^{1/4}\\=3x^2y^2(7^{1/4}x^{1/4}y^{3/4})\\=3x^2y^2(7xy^3)^{1/4}\\=3x^2y^2\sqrt[4]{7xy^3}\)

An equation that describes the graph include the following: C. y = |x – 1| + 2.

In Mathematics and Geometry, the translation of a graph to the right simply means adding a digit to the numerical value on the x-coordinate of the pre-image while the translation of a graph upward simply means adding a digit to the numerical value on the y-coordinate (y-axis) of the pre-image.

Since the parent function is f(x) = |x|, g(x) or y would be created by translating f(x) one (1) unit to the right and two units upward as follows;

f(x) = |x|

g(x) = f(x - 1) + 2

y = |x – 1| + 2

Step-by-step explanation:

Answer:

Confidence Interval = (1.41, 1.59)

Step-by-step explanation:

To construct a confidence interval for the population mean, we can use the following formula:

Confidence Interval = sample mean ± (margin of error * standard error)

where the standard error is equal to the standard deviation divided by the square root of the sample size.

Given the information provided, we can calculate the standard error as:

standard error = 2.16 / sqrt(1370) = 0.058

Then, we can calculate the margin of error as 0.12.

Substituting these values into the formula, we get:

Confidence Interval = 1.5 ± (0.12 * 0.058)

Confidence Interval = (1.41, 1.59)

Therefore, we can interpret the 95% confidence interval as follows: we are 95% confident that the true population mean of the number of days that people feel lonely in the past 7 days is between 1.41 and 1.59. This means that if we were to take many samples of 1370 subjects and compute the confidence intervals for each sample using the same method, we would expect about 95% of the intervals to contain the true population mean.

Answer:

3cm

Step-by-step explanation:

The formula for the volume of the cuboid is \(w*l*h=volume\)

We already have the length, width, and volume, so we have to plug it in to the equation.

\(15*10*h=450\) (Just a heads up in case you didn't know: the centimeters cubed is just part of the units, so you don't need to worry about it when plugging it in to the equation.)

To solve for h:

1. Multiply 15 and 10

\(150*h=450\)

2. Divide both sides by 150

\(h = 450/150\)

h = 3

This is in centimeters, so the final answer is 3cm.

The height of a cuboid with a volume of 450cm³ with a length of 10cm and width of 15cm is 3cm.

The volume of a cuboid can be calculated using the following formula:

Volume = length × width × height

According to this question, the volume of a cuboid is 450cm³ and has a length of 10cm and the width is 15cm. The height is as follows:

450cm³ = 15cm × 10cm × h

450cm³ = 150²h

h = 450/150

h = 3

Therefore, the height of a cuboid with a volume of 450cm³ with a length of 10cm and width of 15cm is 3cm.

La edad actual de José es de 30 años.

Para resolver este problema, primero debemos establecer ecuaciones basadas en la información proporcionada. Llamemos "x" a la edad actual de José y "y" a la edad actual de Ana. Según la primera condición, la edad de Ana es la mitad de la edad de José, por lo que podemos escribir la ecuación: y = (1/2)x.

La segunda condición nos dice que dentro de 10 años, sus edades serán dos tercios de sus edades actuales. Esto se puede expresar como: (x + 10) * (2/3) = y + 10.

Reemplazando el valor de y en la segunda ecuación con la primera ecuación, obtenemos: (x + 10) * (2/3) = (1/2)x + 10.

Resolviendo esta ecuación, podemos simplificarla y llegar a: 2(x + 10) = 3[(1/2)x + 10].

Al resolver la ecuación resultante, encontramos que x = 30.

The transformation function can be represented as vwxyz \($\rightarrow$\)qrstu = (v,w,x,y,z) \($\rightarrow$\) (q,r,s,t,u).

This algebraic representation of the transformation of pentagon vwxyz into pentagon qrstu is using the notation of a function. A function takes an input (in this case, the coordinates of pentagon vwxyz) and produces an output (in this case, the coordinates of pentagon qrstu). This transformation can be represented by the notation (v,w,x,y,z) \($\rightarrow$\) (q,r,s,t,u). This notation means that the coordinates (v,w,x,y,z) are being transformed into the coordinates (q,r,s,t,u). This notation is a concise way of expressing the transformation of pentagon vwxyz into pentagon qrstu. It is important to note that the transformation itself is not specified; the notation is simply used as a way of representing the transformation.

The solution is,  the domain is: x ∈ (-∞, ∞).

Here, we have,

When we have two functions, f(x) and g(x), the composite function:

(f°g)(x)

is just the first function evaluated in the second one, or:

f( g(x))

And the domain of a function is the set of inputs that we can use as the variable x, we usually start by thinking that the domain is the set of all real numbers, unless there is a given value of x that causes problems, like a zero in the denominator, for example:

f(x) = 1/(x + 1)

where for x = -1 we have a zero in the denominator, then the domain is the set of all real numbers except x = -1.

Now, we have:

f(x) = x^2

g(x) = x + 9

then:

(f ∘ g)(x) = (x + 9)^2

And there is no value of x that causes problems here, so the domain is the set of all real numbers, that, in interval notation, is written as:

x ∈ (-∞, ∞)

(g ∘ f)(x)

this is g(f(x)) = (x^2) + 9 = x^2 + 9

And again, here we do not have any problem with a given value of x, so the domain is again the set of all real numbers:

x ∈ (-∞, ∞)

(f ∘ f)(x) = f(f(x)) = (f(x))^2 = (x^2)^2 = x^4

And for the domain, again, there is no value of x that causes a given problem, then the domain is the same as in the previous cases:

x ∈ (-∞, ∞)

(g ∘ g)(x) = g( g(x) ) = (g(x) + 9) = (x + 9) +9 = x + 18

And again, there are no values of x that cause a problem here,

so the domain is:

Answer:

a = 36

Step-by-step explanation:

For the system to have no solution, the two lines must have the same slope and different y -intercept, that is, be parallel lines.

The slope of the first line is "-1/2" (negative one half) when we solve for y:

\(y = -\frac{1}{2} x+\frac{11}{6}\)

so we want the slope of the second line to be the same, and the y-intercept to be different:

\(y=-\frac{a}{72} x+\frac{61}{36}\)

We see that the y-intercepts are different, so all is needed now is to find the appropriate a that gives a slope = -1/2, and that a value is 36.

Answer:

|Z| = |-1.36| < 1.645 at 0.1 level of significance

The null hypothesis is accepted

A manufacturer of banana chips are filling machine works correctly at the mean 449

Step-by-step explanation:

Step(i):-

Given mean of the Population(μ) = 449

The Standard deviation of the population(σ) = 22

size of the sample 'n' = 36

mean of the sample(x⁻) = 444

Given the level of significance(α) = 0.1

Critical value Z = 1.645

Step(ii):-

Null hypothesis:H₀:

A manufacturer of banana chips would like to know whether its bag filling machine works correctly at the 449.0

(μ) = 449

Alternative Hypothesis:H₁: (μ) ≠ 449

Test statistic

                  \(Z = \frac{x^{-} -mean}{\frac{S.D}{\sqrt{n} } } \\= \frac{444-449}{\frac{22}{\sqrt{36} } }\)

                 = -1.36

Final answer:-

|Z| = |-1.36| < 1.645 at 0.1 level of significance

The null hypothesis is accepted

The entropy of the outcome of this experiment = 9

A probability is a number that reflects the chance or likelihood that a particular event will occur. Probabilities can be expressed as proportions that range from 0 to 1, and they can also be expressed as percentages ranging from 0% to 100%.

Given that,

A coin having probability p=2/3

Heads is flipped 6 times

If the coin is flipped 6 times

The Total Number of Trial in the Experiment =2/3

It comes up heads 6 times

This Means: Number of Successful Outcome of HEADS =6

In an experimental probability,

Experimental probability of the coin’s coming up heads

=Number of Successful Outcome of HEADS/Total Number of Trials in the Experiment

= 6/(2/3)

From the question we are told that

Altitude of Height 1.4miles

a) From the question

\(f(x)=ax3+bx2+cx+d\) on interval (-4,0)

The descent can be expressed in \(\triangle _x =-4,0\)

therefore  initial points is (-4 , 1.4).

final co-ordinate is given by (0,0) as its landing

Mathematically solving in above  cubic equation

 \(0 = 0 + 0 + 0 + d \\\)

\(d = 0\)

\(1.4 = -64a + 16b -4c + d\)

\(1 = -45.7a + 11.4b-2.9c+d\)

Generally in this case Slope of tangent at point of descent is zero.assuming flight was initially straight before descent

     \(f'(x) = 3ax^2 + 2bx+c\)

    \(f'(-4) = 48a -8b + c = 0\)

    \(f'(0) = c = 0\)

Mathematically solving above equations we have

\(a = \frac{1}{40} \ and \ b = \frac{3}{20}\)

Therefore having found a and b the Cubic equation is given as

\(f(x) = \frac{1}{40}x^3 + \frac{3}{20}x^2\)

b)descent at its greatest rate

\(f(x)=\frac{1.4}{40} x^3 + \frac{129}{20} x^2\)

\(f(x)=\frac{1.4}{40} x^3 + \frac{129}{20} x^2\)

If we restrict the domain of the function to the portion of the graph with a positive slope, the domain of the inverse function will be the range of the original function for values of x greater than 4, and its range will be all real numbers greater than or equal to 4.

The given function f(x) = |x – 4| + 6 is a piecewise function that contains an absolute value. The absolute value function has a V-shaped graph, and the slope of the graph changes at the point where the absolute value function changes sign. In this case, that point is x=4.

If we restrict the domain of f(x) to the portion of the graph with a positive slope, we are essentially considering the piece of the graph to the right of x=4. This means that x is greater than 4, or x>4.

The domain of the inverse function, f⁻¹(x), will be the range of the original function f(x) for values of x greater than 4. This is because the inverse function reflects the original function over the line y=x. So, if we restrict the domain of f(x) to values greater than 4, the reflected section of the graph will be the range of f⁻¹(x).

The range of f(x) is all real numbers greater than or equal to 6 because the absolute value function always produces a positive or zero value and when x is greater than or equal to 4, we add 6 to that value. The range of f⁻¹(x) will be all real numbers greater than or equal to 4, as this is the domain of the reflected section of the graph.

Answer:

It is a false statement

The correct statement is -The margin of error from the smaller sample will be \(\sqrt{2}\)  times the margin of error from the larger sample.

Step-by-step explanation:

P.S - The exact question is -

Given - A large restaurant chain is curious what proportion of their

            customers in a given day are new customers. They  are thinking  

            of taking a sample of either n = 50 or nº= 100 customers and

            building a one-sample z interval for  a proportion using the data

            from the sample.

To find - The margin of error from the smaller sample will be 2 times

               the margin of error from the larger sample.

Proof -

We know that

E ∝ \(\frac{1}{\sqrt{n} }\)

For smaller margin, E₁ = \(\frac{1}{\sqrt{50} }\)

For larger margin , E₂ = \(\frac{1}{\sqrt{100} }\)

Now,

\(\frac{E_{1} }{E_{2} } = \frac{\sqrt{100} }{\sqrt{50} } = \sqrt{\frac{100}{50} } = \sqrt{2}\\\)

⇒E₁ = \(\sqrt{2}\) E₂

⇒The margin of error from the smaller sample will be \(\sqrt{2}\)  times the margin of error from the larger sample.

So,

It is a false statement.
