The measures of the angles of a triangle are shown in the figure below. Solve for x.

The correct way to report the results of this experiment is t(23)=2.92, p<0.05.

Therefore answer is D.

The notation 't(24)=2.92, p<0.05' indicates the degrees of freedom (24), the value of the test statistic (2.92), and the level of significance (p<0.05).

The notation "t(23)" indicates that the t-value was calculated with 24 degrees of freedom, which is the number of subjects minus 1. The level of significance (p<0.05) means that the probability of obtaining a t-value of 2.92 or greater by chance alone is less than 5%. This indicates that the results are statistically significant and unlikely to be due to random chance.

Option A is incomplete because it does not indicate the degrees of freedom. Option B is incorrect because it states that the degrees of freedom is 24. Option C is incorrect because it incorrectly states that the probability is greater than 0.05, which would mean that the results are not statistically significant. Therefore the correct answer is option D.

Step-by-step explanation:

The answer is approximately 4.08 But again, it's hard to say for certain without more information about what you're trying to do with this equation

Sure, I'd be happy to help!

The equation you've given is a bit tricky to interpret without more context, but here's my best attempt:

It looks like you're trying to find the value of "A" based on an expression involving some kind of radical, and two terms "a" and "b".

Specifically, it seems like you're taking the cube of two coordinate points (1,0) and (0,b), and then adding those cubes together. Finally, you're taking the nth root of the resulting sum (where "n" is some unspecified number).

So if we plug in some values for "a" and "b", and assume that "n" is equal to, say, 2, we might get something like:

A = 3√[(1,0)^3 + (0,4)^3]

= 3√(1 + 64)

= 3√65

Answer:

[tex]P(x)=3x^4-11x^3+71x^2-275x-100[/tex]

Step-by-step explanation:

Given information:

For any complex number  [tex]z=a+bi[/tex], the complex conjugate of the number is defined as  [tex]z*=a-bi[/tex].  

If f(z) is a polynomial with real coefficients, and z₁ is a root of f(z)=0, then its complex conjugate z₁* is also a root of f(z)=0.

Therefore, if P(x) is a polynomial with real coefficients, and 5i is a root of P(x)=0, then its complex conjugate -5i is also a root of P(x)=0.

So the zeros of the function are: 5i, -5i, 4, and -1/3.

The zeros of a function P(x) are the x-values of the function such that the P(x)=0.  According to the Factor Theorem, if P(x) is a polynomial, and P(a)=0, then (x - a)  is a factor of P(x).

Therefore, the factors of the function are:

[tex]x=5i \implies (x-5i)[/tex]

[tex]x=-5i \implies (x+5i)[/tex]

[tex]x=4 \implies (x-4)[/tex]

[tex]x=-\dfrac{1}{3} \implies (3x+1)[/tex]

So the polynomial in factored form is:

[tex]P(x)=a(x-5i)(x+5i)(x-4)(3x+1)[/tex]

As we have not been given a specific leading coefficient, let us assume it is one.

[tex]P(x)=(x-5i)(x+5i)(x-4)(3x+1)[/tex]

To write the polynomial in standard form, expand and simplify.

[tex]\begin{aligned}P(x)&=(x-5i)(x+5i)(x-4)(3x+1)\\&=(x^2+5ix-5ix-25i^2)(3x^2+x-12x-4)\\&=(x^2-25(-1))(3x^2-11x-4)\\&=(x^2+25)(3x^2-11x-4)\\&=3x^4-11x^3-4x^2+75x^2-275x-100\\&=3x^4-11x^3+71x^2-275x-100\end{aligned}[/tex]

Answer: $1.46 less

Step-by-step explanation:

Lets find how much each bottle is first for Store B, to do that divide 29.10 divided by 15 and you should get 1.94 meaning each bottle of juice is $1.94. Next, lets find how much each bottle costs in store A. You can take any number from the total cost and divide it by the bottles and you should get the same thing. Lets do the first one 2.40 divided by 5 equals 0.48. If you want to check you can multiply 0.48 by any number of bottles and you should get the total cost. Now we have to find how much less Store A costs, to do so we subtract store B (1.94) and store A (0.48) and you should get $1.46.

What does a math angle mean?

An angle is made up of two rays (half-lines) that have a shared termination. The rays serve as the angle's sides, occasionally serving as the angle's legs and occasionally serving as its arms, while the latter is referred to as the vertex of the angle.

                                           A figure that is created by two rays or lines that have the same endpoint is known as an angle in plane geometry. The Latin word "angulus," which meaning "corner," is the source of the English term "angle". The vertex, which is the shared terminal of the two rays, is referred to as the side of an angle.

The three integers are 11, 13, and 15.

Explanation:We shall consider the integers as x, 

(x+2), and (x+4).

The sum of these is 39, so we can write:

x+(x+2)+(x+4)=39

Open the brackets and simplify.

x+x+2+x+4=393x+6=39

Subtract 6 from each side.

3x=33

Answer:

y = -5x

Step-by-step explanation:

y = -5x;

[tex]\frac{y}{x}[/tex] = -5;

y:x=-5:1

The equation solved for the variable x is:

[tex]x = e^{ W(ln(y))}[/tex]

In any equation of the form:

y = f(x), to make x the subject of the equation, we need to isolate x in one of the sides of the equation, then we will get:

x = g(y).

In this case we have:

xˣ = y

And we want to make x the subject of the equation.

We can start by apliying the natural logarithm in both sides to get:

ln(xˣ ) = ln(y)

x*ln(x) = ln(y)

We can rewrite:

[tex]x = e^{ln(x)}[/tex]

Then our equation becomes:

[tex]e^{ln(x)}*ln(x) = ln(y)[/tex]

Now the Lambert W function is defined as:

[tex]W(x*e^x) = x[/tex]

So if we apply this in both sides, we will get:

[tex]W(e^{ln(x)}*ln(x)) = W(ln(y))\\ln(x) = W(ln(y))[/tex]

Now apply the exponential in both sides and get:

[tex]ln(x) = W(ln(y))\\\\e^{ln(x)} = e^{ W(ln(y))}\\x = e^{ W(ln(y))}[/tex]

That is the equation solved for x.

The estimated distance between the recycling center and your school is approximately 4.47 miles.  

WHAT IS DISTANCE?

Distance is a numerical measurement of the amount of space between two points. In physics, distance is often described as the length of a path traveled by an object from one point to another. Distance is a scalar quantity, which means it has magnitude but not direction. It is typically measured in units such as meters (m), kilometers (km), feet (ft), or miles (mi).
Distance is an important concept in many fields, including physics, mathematics, geography, and engineering. It is used to describe the separation between two objects or locations, and to calculate various quantities such as speed, velocity, and acceleration.

To estimate the distance between the recycling center and your school, we can use the distance formula:

distance = √((x₂ - x₁)² + (y₂ - y₁)²)

where (x₁, y) represents the coordinates of your school, (x₂, y₂) represents the coordinates of the recycling center, and the √ symbol denotes the square root.

From the problem statement, we know that:

Your school is 4 miles east and 1 mile south of your apartment. Therefore, the coordinates of your school are (4, -1).

The recycling center is 2 miles east and 3 miles north of your apartment. Therefore, the coordinates of the recycling center are (2, 3).

Substituting these values into the distance formula, we get:

distance = √((2 - 4)²+ (3 - (-1))²)

= √((-2)² + (4)²)

= √(4 + 16)

= √20

≈ 4.47 miles

Therefore, the estimated distance between the recycling center and your school is approximately 4.47 miles.

Step-by-step explanation:

The exact expression for g(x) is 2.25cos((2π/4.5)×(x-3.5)) - 4.

A function can be represented using a formula or an equation, and it can be graphed on a coordinate plane. The input values are typically represented on the x-axis and the output values on the y-axis.

From the given information, we know that the function g(x) has a maximum point at (3.5, -4) and a minimum point at (-1, -5).

The general form of a cosine function is f(x) = A×cos(Bx + C) + D, where A is the amplitude, B is the period, C is the phase shift, and D is the vertical shift.

Since the function has a maximum point at (3.5, -4), we know that the graph has been shifted to the left by 3.5 units. Therefore, we can write the function as g(x) = A×cos(B(x - 3.5)) + D.

Similarly, since the function has a minimum point at (-1, -5), we know that the graph has been shifted upwards by 1 unit. Therefore, we can write the function as g(x) = A×cos(B(x - 3.5)) - 4.

To determine A and B, we can use the fact that the period of the function is 4.5 units (the distance between the maximum and minimum points). Therefore, we have B = 2*pi/4.5.

To determine A, we can use the fact that the amplitude is half the distance between the maximum and minimum points, which is 0.5*(5-(-4)) = 4.5. Therefore, we have A = 4.5/2 = 2.25.

Substituting these values into the equation for g(x), we have:

g(x) = 2.25cos((2π/4.5)×(x-3.5)) - 4

Therefore, the exact expression for g(x) is:

g(x) = 2.25cos((2π/4.5)×(x-3.5)) - 4.

The answer of the given question on the listing the critical numbers is  the critical numbers as x = 3, 6, and 9. and the function has an absolute maximum at x = 9. and the function has an absolute minimum at x = 2.

an absolute maximum occurs at the highest point on the graph of a function over its entire domain. It can be a local maximum or a global maximum, depending on whether there are any other points in the domain that have higher function values. Finding the absolute maximum of a function is important in optimization problems, where we want to find the maximum or minimum value of a function subject to certain constraints.

Based on the graph provided, we can approximate the critical numbers as x = 3, 6, and 9.

To determine whether there is relative maximum, relative minimum, absolute maximum, or absolute minimum at each critical number, we need to examine  behavior of function near each critical number.

At x = 3, the function has a relative maximum, since the graph changes from increasing to decreasing at that point.

At x = 6, the function has a relative minimum, since the graph changes from decreasing to increasing at that point.

At x = 9, the function has a relative maximum, since the graph changes from increasing to decreasing at that point.

Since the graph increases without bound as x approaches 10 from the left, but approaches a finite value as x approaches 10 from the right, the function has an absolute maximum at x = 9.

Since the graph decreases without bound as x approaches 2 from the right, but approaches a finite value as x approaches 2 from the left, the function has an absolute minimum at x = 2.
