Answer:

78.5

Step-by-step explanation:

The radius of the circle is 25 so youu multiply that by 3.14

25*3.14=78.5

The possible probability assignments are a) 0.25 0.25 0.25 0.25 and e) 0.5 0.1 0.3 0.1.

To be possible probability assignments, the probabilities assigned to each color must be non-negative and add up to 1.

a) 0.25 0.25 0.25 0.25: These probabilities add up to 1 and are all non-negative, so they are possible.

b) 0.4 0.3 0.2 0.5: The probabilities do not add up to 1, so this is not possible.

c) 0.4 0.3 1.2 -1.9: The probabilities are not all non-negative and do not add up to 1, so this is not possible.

d) 0 1 0 0: Only one color has a non-zero probability, so this is not possible.

e) 0.5 0.1 0.3 0.1: These probabilities add up to 1 and are all non-negative, so they are possible.

Answer:

Think

Step-by-step explanation:

4x - 6 + 2x = 18

You are solving for x so obviously you have to have your x variable on one side of the equal sign by itself.

So how do you do that? Combine the same calues together and seperate the rest

4x + 2x = 6x

6x = 18 + 6

6x = 24

x = 3

Practice practice practice. Simple stuff. You got this!

Answer:

A. x = 4

Step-by-step explanation:

To answer this question, we first have to combine like terms:

4x - 6 + 2x = 18

6x - 6 = 18

Now, we take away 6 from the left side and add it to the right side:

6x - 6 = 18

     +6   +6

6x = 24

Then, we isolate the variable:

6x = 24

/6     /6

x = 4

The probability of being depressed and wearing cotton clothes is 0.39.

Note that the probability of something happening is the chance of occurrence versus the total possibilities obtainable. So, for the data we are given, we will find the probability of being depressed and wearing cotton clothes this way:

Probability of being depressed and cotton/probability of being cotton

= 122/994 ÷ 311/994

= 122/311

= 0.39

So, the relative risk of being depressed and wearing cotton clothes is 0.39.

Step-by-step explanation:

the answer from the graph is;

(3 , -2)

The given integral ∫(-2 to 1) x^2 dx converges and its value is 3.

To determine if the integral converges or diverges, we evaluate the definite integral ∫(-2 to 1) x^2 dx.

Integrating x^2 with respect to x, we get (1/3) x^3. Evaluating the definite integral over the given bounds, we have:

(1/3) [x^3] from -2 to 1.

Substituting the bounds into the antiderivative expression, we get:

(1/3) [1^3 - (-2)^3] = (1/3) [1 - (-8)] = (1/3) [9] = 3.

Since the value of the integral is a finite number (3), we conclude that the given integral converges. The definite integral has a finite value when evaluated over the interval from -2 to 1.

Therefore, the given integral ∫(-2 to 1) x^2 dx converges and its value is 3.

The function has a horizontal asymptote at y = 3. Other types of discontinuities can also occur in rational functions

A polynomial is a mathematical expression that consists of variables and coefficients, which are combined using arithmetic operations such as addition, subtraction, multiplication, and non-negative integer exponents.

A rational function can have a discontinuity at any point where the denominator of the function becomes zero since division by zero is undefined. These points are called "vertical asymptotes."

For example, consider the rational function f(x) = (x² - 1) / (x - 1). The denominator becomes zero when x = 1, which causes a vertical asymptote at x = 1. At x = 1, the function approaches positive infinity from the left-hand side and negative infinity from the right-hand side. This creates a "hole" or a "removable discontinuity" in the graph of the function.

Another type of discontinuity that can occur in a rational function is a "horizontal asymptote." This occurs when the degree of the numerator is less than the degree of the denominator. In this case, the function approaches a horizontal line (the horizontal asymptote) as x approaches infinity or negative infinity.

For example, consider the rational function f(x) = (3x² - 2x + 1) / (x² + 1). As x approaches infinity or negative infinity, the function approaches the horizontal line y = 3.

Therefore, the function has a horizontal asymptote at y = 3.

Other types of discontinuities can also occur in rational functions, such as "slant asymptotes" or "oscillating behavior," but these are less common and typically require more advanced techniques to identify.

The height of the cliff is approximately 269 feet.

We will be using the tangent function to find the height of the cliff.
Draw a right triangle with the rowboat at one corner, the cliff's base as the adjacent side, and the cliff's height as the opposite side.

The angle of elevation (73.8 degrees) is between the rowboat and the cliff's base.
We are given the adjacent side (75 feet) and we need to find the opposite side (height of the cliff).

To do this, we will use the tangent function:
tan(angle) = opposite side / adjacent side
Plug in the given values:
tan(73.8) = height / 75
Solve for the height:
height = tan(73.8) * 75
Calculate the value:
height ≈ 269.4 feet
Round the height to the nearest foot:
height ≈ 269 feet.

What is Symmetry ?

In common parlance, the term "symmetry" describes a sense of lovely proportion and balance. A more exact meaning of "symmetry" can be found in mathematics, where it typically refers to an object that is unaffected by certain transformations like translation, reflection, rotation, or scaling.

A definition of symmetry in mathematics states that whether one shape is moved, rotated, or flipped, it exactly resembles the other shape. Just fold the paper, draw one-half of the heart at the fold, then cut it out to discover that the other half exactly matches the first half when you are instructed to cut out a "heart" from a piece of paper. The heart-shaped carving is an illustration of symmetry. Symmetry is defined in mathematics as "a mirror image." Symmetry is the property of an image that remains unchanged after a shape has been rotated or flipped. There are patterns in it. You may have heard the word "symmetry" quite a bit in modern times.

(A)

Any two indices will do i!=j Paul's time and the time of the ith runner are equally distributed and independent, hence according to the Symmetry, p (Ai) = p(Aj)= 1/2. Consider the intersection of Ai and Aj. Thus, Paul is outpaced by both runners I and j. There are 6 possible permutations of their times because they are i.id, with Paul being the slowest. P(Ai intersection Aj) hence equals 1/3.

But now wе have that P(Ai intersection Aj)= 1/3 != 1/4 = P(Ai)P(Aj)

thus, events They are not autonomous, Ai and Aj. However, they are only somewhat independent given Paul's timing. Paul can be removed from the narrative if such is the case. Then, only these two runners are left. Events As a result of their independent and equal distribution of times, Aj and AI are independent.

(B)

Define Ij as the random variable indication that indicates whether or not the jth runner is superior to Paul. via means of symmetry. We know p(Ij = 1)=1/2.

We determine that 

E(N) = E(I1+I2 +.......In) 

= nE(i1) 

=nP(I1-1) 

=n/2

using the linearity of expectation.

(C)

Paul's estimated time of completion is t The probability that each runner will finish ahead of Paul is P (time of rumer I t) = F. (t)

By using part (a), we can determine that other runners' times are independent of Paull's time, and that the number of runners who finish faster than Paul has a binomial distribution with the parameters n and F. To come to the conclusion that N/T= t Binom (n, F(t)) and if we choose T at random, N/T Binom (n, F(T)),

(D)

Let's figure out Var (N)

Var (N)=F(Var (N/T)) + Var(E(N/T))

= E(n F(T) (1- F(T)) + Var(on F(T))

according to Eve's Law.

Here, we can use the uniform distribution's universality to produce

F(T) ~Unif (0, 1) = U

Hence symmetry, which states that U I-U, leads to

Var(N) = nE(U2) + n2 var (U)

=n/3 + n2/12,

where E(U2)=1/3

Var(U)=1/12.

The length of side BC is 3 units.

What are trigonometric functions?

Trigonometric functions are mathematical functions that relate the angles and sides of a right triangle.

Sine (sin): the ratio of the length of the side opposite an angle to the length of the hypotenuse of the triangle.

Given that angle ABC is a right angle at C and angle <ABC = 30 degrees, we can use trigonometric ratios to find the length of side BC.

Let BC = x units

Using the trigonometric ratio of sine for angle <ABC, we have:

sin(angle ABC) = opposite / hypotenuse

sin(30°) = BC / AB (opposite side is BC and hypotenuse is AB)

1/2 = x / 6

x = 6 * 1/2

x = 3

Therefore, the length of side BC is 3 units.
