Meagan gets a third of the money that her family earns selling cookies, and the amount that she gets can be shown with the expression m
3
. What is the meaning of the variable m in the expression?

The correct answer is option 1. In a continuous probability distribution, the random variable can take on an infinite number of values within a given range.

This range is typically represented by the interval between two points on the number line, such as 0 and 100. The probability of a particular value occurring is defined as the area under the curve of the probability density function for that distribution, rather than a single value.

Option 2, "may have a probability greater than 1.00" is incorrect as probabilities are always between 0 and 1, inclusive.

Option 3, "has a limited number of values" is incorrect as, by definition, continuous random variables can take on an infinite number of values.

Option 4, "is discrete" is incorrect as a continuous random variable is not limited to a finite or countable number of values.

This is an equation is e⁻¹³⁸ˣ - 5e⁻¹³⁹ × 81y + z = 6

In mathematics, a tangent is a line that touches a curve at a single point and has the same slope as the curve at that point. The tangent can be thought of as an approximation of the curve at the point where it touches it.

The concept of the tangent is used in calculus and other branches of mathematics to study the properties of curves and to analyze their behavior. The derivative of a function at a point is defined as the slope of the tangent to the curve of the function at that point. The derivative is a fundamental concept in calculus and is used to study the rate of change of a function, the optimization of functions, and to solve problems in many different fields.

To find the equation of the tangent plane to the surface z = e^(x - y^5) at the point (3, 3, 6), we need to find the normal vector of the surface at that point, and use that to find the equation of the plane.

The normal vector can be found using the gradient of the surface, which is given by the partial derivatives of the function:

∇f = ∇(e^(x - y^5)) = (e^(x - y^5), -5e^(x - y^5)y^4, 1)

Evaluating this at the point (3, 3, 6), we get:

∇f(3, 3, 6) = (e^(3 - 3^5), -5e^(3 - 3^5)3^4, 1) = (e^-138, -5e^-138 * 81, 1)

So the normal vector of the surface at the point (3, 3, 6) is (e^-138, -5e^-138 * 81, 1).

To find the equation of the tangent plane, we need to find a point on the plane, and use that along with the normal vector. We already know that the point (3, 3, 6) is on the surface, so we can use that as a point on the plane.

Using the point-normal form of a plane, the equation of the tangent plane is given by:

ax + by + cz = d

Where (a, b, c) is the normal vector and (x⁰, y⁰, z⁰) is a point on the plane.

Substituting the values, we get:

e⁻¹³⁸ˣ - 5e⁻¹³⁹ × 81y + z = 6

This is the equation of the tangent plane to the surface z = e^(x - y^5) at the point (3, 3, 6).

The tangent line to the parabola y = x² at the point (6, 36) is (0.141, 1.68)

The equation of the tangent line at the point (6, 36) can be found using the derivative of the function and the point-slope form of a line:

f(x) = x²

f'(x) = 2x

y = f'(x) * (x - 6) + 36

Substituting f'(x) = 2x,

y = 2x * (x - 6) + 36

Now, we can find a unit vector that is parallel to this line by finding a non-zero multiple of the direction vector of the line, which is (1, 2x), and normalizing it.

To normalize, we divide by the magnitude, which is sqrt(1^2 + (2x)^2) = sqrt(1 + 4x^2).

Let's use x = 6:

y = 2 * 6 * (x - 6) + 36

y = 72

So, the direction vector is (1, 12) and its magnitude is sqrt(1 + 144) = sqrt(145) = 7.07.

The unit vector that is parallel to the tangent line is (1/7.07, 12/7.07) = (0.141, 1.68).

A real estate agent has 17 properties that she shows,  the probability of selling no more than 3 properties in one week is 0.0464 or 4.64%.

There are only two possible outcomes for each attribute. Selling one home does not affect the likelihood of selling another. Therefore, to answer this query, we employ the binomial probability distribution.

Binomial probability distribution

The probability of precisely x successes on n repeated trials is known as a binomial probability, and X can only have two possible outcomes.

[tex]P(X=x) = C_{n} , x.P^x.(1-P)^{n-x}[/tex]

Given by the following formula.

[tex]C_{n} , x = \frac{n!}{x! (n-x)!}[/tex]

And p is the probability of X happening.

n = 17

P = 0.4

P(X≤3) = P(X=0) + P(X=1) + P(X=2) + P(X=3)

In which,

[tex]P(X=x) = C_{n} , x.P^x.(1-P)^{n-x}[/tex]

[tex]P(X=x) = C_{n} , x.P^x.(1-P)^{n-x}\\P(X=0) = C_{17} ,0.(0.4)^0.(0.6)^{17} = 0.0002\\P(X=1) = C_{17} ,1.(0.4)^1.(0.6)^{16}=0.0019\\P(X=2) = C_{17} ,2.(0.4)^2.(0.6)^{15}=0.0102\\P(X=3) = C_{17} ,3.(0.4)^3.(0.6)^{14}=0.0341[/tex]

P(X≤3) = P(X=0) + P(X=1) + P(X=2) + P(X=3) = 0.0002 + 0.0019 + 0.0102 + 0.0341  = 0.0464

Therefore probability of selling no more than 3 properties in one week is 0.0464 or 4.64%.

Without additional information, it is impossible to determine the probability that the toy is not cool.

Without additional information, it is impossible to determine the probability that the toy is not cool. This is because the color of the toy does not provide any information about its coolness. For example, a red toy could be a cool action figure or a boring stuffed animal. Therefore, the color of the toy does not provide any insight into its coolness, and thus any probability assigned to the toy being not cool would be purely speculative and not based on any information. In order to determine the probability that the toy is not cool, we would need additional information, such as what the toy is, what its features are, or who makes it.

lim (x → a) f(x) = ∞ , The limit does not exist and is neither ∞ nor - ∞

The vertical line test is used to verify function. That is, a graph must have a unique y value for it to be referred to as a function for a certain (unique) value of x. If for a particular x, and y values are coming it means it is not a function. If it crosses y-axis twice it means for a particular x value , two different value of y will exist. And that is not possible for a function

From the graph, we know that limit at point a is:

lim (x→a) f(x) exists if and only if

lim (x →a⁺) f(x) = lim (x→a⁻) f(x) and ≠ ∞

∴ right hand side limit = left hand side limit

lim (x →a⁺) f(x) = - ∞

lim (x →a⁻) f(x) = - ∞

Step-by-step explanation:

Rational Root theorem is when we divide the factors of last term by the factors of first term:

[tex]\displaystyle{\text{possible rational roots} = \dfrac{\text{factors of the coefficient of last term (constant)}}{\text{factors of lead coefficient (coefficient of first term)}}}[/tex]

Our constant (last term) is -27. The factors of -27 can be ±1, ±3, ±9, ±27

Our lead coefficient is 2. The factors of 2 can be ±1 and ±2.

It appears that for any ax + b, a combination of ax + b and 2a+d equals 1. This can be proven by setting P(x) = -ax - b and Q(x) = 2a+d.

(a) No combination of 2x + 5 and 3 can equal 1.

Let P(x) and Q(x) be two integer polynomials such that P(x)·(2x + 5) + Q(x)·3 = 1.

This can be written as P(x)·2x + P(x)·5 + Q(x)·3 = 1.

Rearranging, we get P(x)·2x + (P(x)·5 + Q(x)·3) = 0

This implies that P(x)·2x = -(P(x)·5 + Q(x)·3).

Since both P(x) and Q(x) are integer polynomials, it follows that P(x)·2x and (P(x)·5 + Q(x)·3) are both integers.

However, this is impossible since the left hand side is an even integer, while the right hand side is an odd integer.

Therefore, no combination of 2x + 5 and 3 can equal 1.

(b) A combination of 2x + 5 and 4 that equals 1 is P(x) = -2x - 5 and Q(x) = 4.

(c) No combination of 15x+9 and 25 equals 1. However, a combination of 15x+9 and 20 equals 1. This can be seen by setting P(x) = -15x - 9 and Q(x) = 20.

An algebraic equation, also known as a polynomial equation, is a mathematical equation of the form P=0, where P is a polynomial with coefficients in some field, most commonly the field of rational numbers. In its most basic form, an equation is a mathematical statement that indicates that two mathematical expressions are equal. 3x + 5 = 14, for example, is an equation in which 3x + 5 and 14 are two expressions separated by a 'equal' sign.

Here,

Let's call the original value of x as X. Then, we can write the following equation:

X - X/6 - X/13 = 1000

Expanding the first two terms on the left-hand side:
