Answer:

X=5

Step-by-step explanation:

Answer:

x = -13/4

Step-by-step explanation:

2x + 1 : 4x + 13 = "number of purple tiles" : "number of white tiles"

We know that "of the tiles" are purple, so we can also write:

(number of purple tiles) / (number of total tiles) =

Combining these two equations, we get:

(2x + 1) / (2x + 1 + 4x + 13) =

Simplifying the denominator, we get:

(2x + 1) / (6x + 14) =

Cross-multiplying, we get:

(2x + 1) = (6x + 14)

Expanding the brackets, we get:

2x + 1 = 6x + 14

Subtracting 2x from both sides, we get:

1 = 4x + 14

Subtracting 14 from both sides, we get:

-13 = 4x

Dividing both sides by 4, we get:

x = -13/4

However, since x represents the number of tiles, it doesn't make sense for it to be negative. Therefore, there must have been a mistake in the question or my working so I'm not entirely sure. Hopefully the work can help out a little though.

The correct answer is: None of these answers is correct.The random variable representing the time lapsed during the run in this experiment is a continuous random variable.

I apologize for the previous incorrect answer. The random variable representing the time lapsed during the run in the given experiment is a continuous random variable. A continuous random variable can take on any value within a specified range or interval. In this case, the time elapsed during the run can theoretically be any non-negative real number, allowing for an infinite number of possible outcomes. It is not restricted to specific discrete values or intervals. Examples of continuous random variables include time, length, weight, and temperature.

Continuous random variables are characterized by their probability density function (PDF), which describes the likelihood of observing different values. In contrast, a discrete random variable would have a finite or countable set of possible values, such as the number of heads obtained in a series of coin flips.

Negation is a logical operator that is used to form the negation of a statement by reversing the truth value of the statement. Thus, when simplifying a statement, the negation should be placed right before the variables or statements in the statement to form the negated statement. This is done to clearly express the logical relationship between the variables and the negation.

a. ¬P ∨ Q

b. ¬(P ∨ Q) ∨ (Q ∧ R)

c. (¬P ∨ Q) ∨ (¬R ∧ R)

d. ¬(¬Sam ∧ ¬Chris) ∨ (¬Chris ∧ ¬Woman)

For example, in statement a, the negation of the statement is expressed as ¬P ∨ Q, where the negation is placed right before the variable P. Similarly, in statement b, the negation of the statement is expressed as ¬(P ∨ Q) ∨ (Q ∧ R), where the negation is placed right before the statement (P ∨ Q).

a) The gcd of 200837 and 151406 is 23.

b) The gcd of 6994728 and 34488036 is 1572.

a) To find the gcd of 200837 and 151406 using the Euclidean Algorithm, we divide the larger number (200837) by the smaller number (151406) and take the remainder. We then divide the smaller number (151406) by the remainder, and continue this process until the remainder is zero. The last non-zero remainder obtained is the gcd.

Using the Euclidean Algorithm:

200837 = 1 * 151406 + 49431

151406 = 3 * 49431 + 31213

49431 = 1 * 31213 + 18218

31213 = 1 * 18218 + 12995

18218 = 1 * 12995 + 5223

12995 = 2 * 5223 + 2549

5223 = 2 * 2549 + 124

Since the remainder has become zero (124), the gcd of 200837 and 151406 is the last non-zero remainder, which is 124.

b) Similarly, to find the gcd of 6994728 and 34488036, we apply the Euclidean Algorithm:

34488036 = 4 * 6994728 + 270616

6994728 = 25 * 270616 + 18508

270616 = 14 * 18508 + 11184

18508 = 1 * 11184 + 7324

11184 = 1 * 7324 + 3860

7324 = 1 * 3860 + 3464

3860 = 1 * 3464 + 396

3464 = 8 * 396 + 16

396 = 24 * 16 + 12

16 = 1 * 12 + 4

12 = 3 * 4 + 0

Since the remainder has become zero, the gcd of 6994728 and 34488036 is the last non-zero remainder, which is 4.

The exact value of the integral ∫b0 (x^6/3 * 6x) dx is b^8.

The Fundamental Theorem of Calculus (FTC) is a theorem that connects the two branches of calculus: differential calculus and integral calculus. It states that differentiation and integration are inverse operations of each other, which means that differentiation "undoes" integration and integration "undoes" differentiation.

The first part of the FTC (also called the evaluation theorem) states that if a function f(x) is continuous on the closed interval [a, b] and F(x) is an antiderivative of f(x) on that interval, then:

∫ab f(x) dx = F(b) - F(a)

In other words, the definite integral of a function f(x) over an interval [a, b] can be evaluated by finding any antiderivative F(x) of f(x), and then plugging in the endpoints b and a and taking their difference.

The second part of the FTC (also called the differentiation theorem) states that if a function f(x) is continuous on an open interval I, and if F(x) is any antiderivative of f(x) on I, then:

d/dx ∫u(x) v(x) f(t) dt = u(x) f(v(x)) - v(x) f(u(x))

In other words, the derivative of a definite integral of a function f(x) with respect to x can be obtained by evaluating the integrand at the upper and lower limits of integration u(x) and v(x), respectively, and then multiplying by the corresponding derivative of u(x) and v(x) and subtracting.

Both parts of the FTC are fundamental to many applications of calculus in science, engineering, and mathematics.

Let's start by finding the antiderivative of the integrand:

∫ (x^6/3 * 6x) dx = ∫ 2x^7 dx = x^8 + C

Using the Fundamental Theorem of Calculus, we have:

∫b0 (x^6/3 * 6x) dx = [x^8]b0 = b^8 - 0^8 = b^8

Therefore, the exact value of the integral ∫b0 (x^6/3 * 6x) dx is b^8.

Answer:

it needed your to focus on school work , homework and work hard to make yourself feel ready

It can be determined that a relation represented as an equation is a function if and only if for each value on x-axis, there is a corresponding value on Y-axis.

which also signifies that for each value of x , there is a value of y which exists and is real.

A function is a mapping from one set to another such that nothing in the first set is mapped to more than one thing in the second set.

Or in simple words if there is no corresponding value of y for any x, then that is not a function.

For example,

\(x^{2} +y^{2}\)=1

when the value of x is 0 , then value of y is 1 or -1, Thus, it will not be a function.

The standard deviation for a binomial probability distribution is : √npq.

The correct option is (D) i.e., square root of npq

The standard deviation of a random variable, sample, statistical population, data set or probability distribution is the square root of its variance.

For a binomial distribution,

µ = np, which signifies the expected number of successes.

\(\sigma^2\) = npq , \(\sigma^2\) is the variance.

Since, the standard deviation is the square root of the variance,

Therefore, σ = Standard deviation = √npq

Thus, the standard deviation for a binomial probability distribution is given by √npq.

Competent communicators achieve effectiveness mostly by adjusting their behaviors to suit the person they are communicating with and the situation they find themselves in. While other factors, like having a broad vocabulary or giving feedback, play a part in effective communication, the former is considered the most crucial.

Research suggests that competent communicators achieve effectiveness mostly through adjusting their behaviors depending on the person they are communicating with and the situation they are in. This is option e. of your question. Communicating effectively involves behaviors like active listening, understanding the other person's point of view, being able to express thoughts and ideas clearly, and being polite and respectful. While a broad vocabulary (option b.) can be useful, it is not as crucial as adapting your behavior to fit the situation. Moreover, giving feedback (option d.) is a part of effective communication but not the sole defining factor. Apologizing when offending others (option c.) is also important but it doesn't necessarily make one a competent communicator. Using the same type of behavior in various situations (option a.) might not always work, as different situations and individuals require different communication styles.

201 food calories (kcal) would be sufficient for a well-conditioned athlete to metabolize in doing the same work with an efficiency of 25%

Assuming input the 25% into equation and work

with the help of the equation, we know:

η = work_out / work_in

therefore we get, 0.25 = (2.10e5) / (kcal)

then, kcal = (2.10e5J)/(0.25)

kcal = 2.10e5 J / 0.25

upon dividing the following we get the answer,

kcal = 840e3J

now we need to convert the Joules to kcal and we get,

we know that, 1kcl = 4184J

therefore, 840e3 / 4184 = 201 kcal

The distance from the origin to the center of the sphere is  \(\sqrt{43}\), so we have \(x^{2} +x^{2} +(5-0)^{2} =43\) This gives us \(a^{2} +b^{2} =38\)

The radius of the sphere is the distance from the center of the sphere to the point where the sphere touches the xz-plane. This distance is equal to the length of the hypotenuse of a right triangle with legs of length a and b. Therefore, the radius of the sphere is \(\sqrt{a^{2}+ b^{2} } =\sqrt{38}\)
