A qué se debe que un fluido pierda presión al pasar por un ducto más pequeño​

Answer:

C

Step-by-step explanation:

Just took the quiz

Based on the graphed values of f(x) and independent variable x, the graph shows that C. k is greater than zero.

We have a c value of -1 which is where the y axis is intercepted.

We know that k isn't zero because the x and y values are not the same. We can also tell that k is not less than 0 because if it was, the f(x) for the smaller x value would lead to a larger f(x) value.

The only logical conclusion therefore, is that k is greater than zero.

The z-value is 1.44 in the confidence interval formula for a population mean at an 85% confidence level when you know σ.

1. Determine the desired confidence level: In this case, the confidence level is 85%.

2. Find the remaining area outside the confidence level: Since the confidence interval is symmetrical around the mean, we'll divide the remaining area by 2. Thus, the area outside the 85% confidence interval is 100% - 85% = 15%. Since it's divided equally on both sides, we'll have 7.5% on each tail.

3. Convert the percentage to a decimal: To find the z-value in the z-table, we need to convert the percentage to a decimal. In this case, 7.5% = 0.075.

4. Locate the value in the z-table: The z-table gives the area to the left of the z-value. Since we want the area to the right (the tail), we'll subtract our decimal from 1: 1 - 0.075 = 0.925. Look up 0.925 in the z-table to find the corresponding z-value.

5. Round the z-value to 2 decimal places: The z-value corresponding to 0.925 in the z-table is approximately 1.44 according to the confidence interval formula.

The probability that the policyholder is a home renter, given that a renter still has a policy one year after purchase, is approximately 0.260 or 26.0%.

Let H denote the event that the policyholder is a home renter, and A denote the event that the policyholder is an apartment renter. We are given that P(H) = 0.4 and P(A) = 0.6.

Let T denote the time from policy purchase until policy cancellation. We are also given that T | H ~ Exp(1/4), and T | A ~ Exp(1/2).

We want to calculate P(H | T > 1), the probability that the policyholder is a home renter, given that a renter still has a policy one year after purchase:

P(H | T > 1) = P(H and T > 1) / P(T > 1)

Using Bayes' theorem and the law of total probability, we have:

P(H | T > 1) = P(T > 1 | H) * P(H) / [P(T > 1 | H) * P(H) + P(T > 1 | A) * P(A)]

To find the probabilities in the numerator and denominator, we use the cumulative distribution function (CDF) of the exponential distribution:

P(T > 1 | H) = e^(-1/4 * 1) = e^(-1/4)

P(T > 1 | A) = e^(-1/2 * 1) = e^(-1/2)

P(T > 1) = P(T > 1 | H) * P(H) + P(T > 1 | A) * P(A)

= e^(-1/4) * 0.4 + e^(-1/2) * 0.6

Putting it all together, we get:

P(H | T > 1) = e^(-1/4) * 0.4 / [e^(-1/4) * 0.4 + e^(-1/2) * 0.6]

≈ 0.260

Therefore, the probability that the policyholder is a home renter, given that a renter still has a policy one year after purchase, is approximately 0.260 or 26.0%.

The residential buildings' total assessed land value has the smallest standard deviation.

To determine the standard deviations for the commercial and residential buildings' total assessed land value and total assessed parcel value, we would need access to a specific dataset that includes these values. However, based on general trends and assumptions, residential buildings' total assessed land value is likely to have the smallest standard deviation.

Residential properties typically exhibit more homogeneity compared to commercial properties. Residential neighborhoods often consist of similar types of properties, with comparable land values within a specific area. As a result, the assessed land values for residential buildings are more likely to cluster around a mean value, resulting in a smaller standard deviation.

In contrast, commercial properties can vary significantly in terms of size, location, and intended use. They may be diverse in terms of their land value and parcel value. The assessed land values and parcel values for commercial buildings are more likely to have a wider range of values, leading to a larger standard deviation.  

Therefore, based on these general characteristics, the residential buildings' total assessed land value is expected to have the smallest standard deviation compared to the commercial buildings' total assessed land value and total assessed parcel value.

There are 462 ways to choose 5 books from a shelf of 12, if you cannot choose two adjacent books.

To solve this problem, we can use a technique called "complementary counting." First, let's find the total number of ways to choose 5 books from a shelf of 12. This is simply 12 choose 5, which is:
12! / (5! × 7!) = 792
Now, let's count the number of ways to choose 5 books from a shelf of 12 where two adjacent books are chosen. We can do this by treating the adjacent books as a single unit, and then choosing 4 more books from the remaining 11. This gives us:
11 choose 4 = 330
So, there are 330 ways to choose 5 books from a shelf of 12 where two adjacent books are chosen.
Finally, we can subtract this number from the total number of ways to choose 5 books to get the number of ways to choose 5 books where no two adjacent books are chosen:
792 - 330 = 462
Therefore, there are 462 ways to choose 5 books from a shelf of 12, if you cannot choose two adjacent books.

The vertical line test is a visual test used to determine whether or not a graph is a function. To perform this test, simply draw a straight vertical line multiple times on different parts of the graph.

If a vertical line intersects with the graph at one point, then it's a function.

If a vertical line intersects with the graph at multiple points, then it's not a function.

Examples:

The integral of f(x, y, z) = (x + y + z)/(x^2 y^2 z^2) over the path r(t) = 3ti + 3tj + tk, 0 ≤ t ≤ 1 is: -14/(729√19).

To evaluate the line integral of f(x, y, z) over the given path r(t), we need to substitute the parameterization of the path into the function f(x, y, z) and then compute the integral.

Step 1: Substitute the parameterization of the path into the function f(x, y, z):

f(r(t)) = [(3t) + (3t) + (t)] / [(3t)^2 (3t)^2 (t)^2]

= (7t)/(729t^6)

= 7/(729t^5)

Step 2: Compute the differential of the path:

dr(t) = (3i + 3j + k) dt

Step 3: Compute the magnitude of the differential:

|dr(t)| = sqrt((3)^2 + (3)^2 + (1)^2) dt

= sqrt(19) dt

Step 4: Set up the line integral:

∫[0,1] (f(r(t)) |dr(t)|)

= ∫[0,1] [(7/(729t^5)) * sqrt(19)] dt

Step 5: Evaluate the integral:

= (7/729) * sqrt(19) ∫[0,1] t^(-5/2) dt

To compute the integral ∫[0,1] t^(-5/2) dt, we can use the power rule of integration:

= (7/729) * sqrt(19) * [(t^(-3/2))/(-3/2)] | [0,1]

= -14/(729√19) * [1/(2√t^3/2)] | [0,1]

= -14/(729√19) * (1/(2√1^3/2) - 1/(2√0^3/2))

= -14/(729√19) * (1 - 0)

= -14/(729√19)

Therefore, the integral of f(x, y, z) over the given path r(t) is -14/(729√19).

Step-by-step explanation:

In a standard 52-card deck, there are 20,358 ways to pick an (unordered) subset of 6 cards that contains at least one Ace, at least one King, at least one Queen, and at least one Jack.

When selecting a subset of 6 cards from a standard 52-card deck, the main objective is to ensure that the subset contains at least one Ace, one King, one Queen, and one Jack. To calculate the number of ways this can be achieved, we can break it down into steps.

Step 1: Select one Ace, King, Queen, and Jack

There are 4 ways to choose one Ace, 4 ways to choose one King, 4 ways to choose one Queen, and 4 ways to choose one Jack.

Step 2: Select two additional cards from the remaining 48 cards

After selecting one Ace, one King, one Queen, and one Jack, we are left with 48 cards. To complete the subset of 6 cards, we need to choose two more cards from this remaining set. The number of ways to select two cards from 48 is calculated using combinations, denoted as "48 choose 2," which is equal to 1,128.

Step 3: Multiply the results

To determine the total number of ways, we multiply the results of each step. Therefore, the total number of ways to pick an (unordered) subset of 6 cards that contains at least one Ace, one King, one Queen, and one Jack is 4 * 4 * 4 * 4 * 1,128 = 20,358.

To solve the equation 6x + 5 + 2x - 11 = 90, the value of x can be found by simplifying the equation and solving for x. Hence solution to the equation 6x + 5 + 2x - 11 = 90 is x = 12.

Combining like terms, we have 8x - 6 = 90. To isolate the variable term, we can add 6 to both sides of the equation, resulting in 8x = 96. Finally, dividing both sides of the equation by 8 gives us the solution: x = 12.

In the given equation, we have a combination of variables (x) and constants (numbers). To solve the equation, our goal is to simplify it by combining like terms and isolating the variable term on one side of the equation.

Starting with 6x + 5 + 2x - 11 = 90, we can combine the x terms by adding 6x and 2x to get 8x. The equation becomes 8x + 5 - 11 = 90. Simplifying further, we have 8x - 6 = 90.

To isolate the variable term, we need to eliminate the constant term on the same side as the variable. In this case, we can subtract 6 from both sides of the equation, giving us 8x = 96.

Finally, to find the value of x, we divide both sides of the equation by the coefficient of x, which is 8. This gives us x = 12. Therefore, the solution to the equation 6x + 5 + 2x - 11 = 90 is x = 12.

The altitude of a right triangle, 'h', which intersects with the hypotenuse side of the right triangle at a point such that it creates two segments, 'a' and 'b' on the hypotenuse side , then we have;

h = √(a·b)

Therefore, we have;

Description      \({}\)                                                                                 Proportion

The altitude of ΔAYES is the geometric mean between m and n   \(\dfrac{m}{a} =\dfrac{a}{n}\)

a² = m·n → a = √(m·n)

The shorter leg, s, is the geometric mean between h and m   \(\dfrac{m}{s} =\dfrac{s}{h}\)

s² = m·h → s = √(m·h)

The longer leg, b, is the geometric mean between h and n   \(\dfrac{n}{b} =\dfrac{b}{h}\)

b² = n·h → s = √(n·h)

The noun names in decimal and binary equivalents represent the same numeric value but in different positional numeral systems.

There is a significant difference between the two systems.

While the decimal number system uses ten digits (0 through 9), the binary number system employs only two digits: 0 and 1.

Furthermore, in decimal numbers, the weight of each digit is a multiple of ten, whereas in binary numbers, the weight of each digit is a multiple of two.

The weight of each digit in a binary number is always a power of 2. As the digit moves from the right to the left, the weight of the digit increases.

The weight of the first digit on the right-hand side is 20. The weight of the second digit from the right is 21, and the weight of the third digit from the right is 22.

Similarly, the weight of the fourth digit from the right is 23, and so on.

In the decimal system, the weight of the first digit from the right is 100. The weight of the second digit from the right is 101, and the weight of the third digit from the right is 102, and so on.

So, this is how the noun names relate between the decimal and binary equivalents.

The equation of the parabola with the given vertex and focus is x^2 = 24y.

What is parabola?

A parabola is a U-shaped curve that is symmetric and can either open upward or downward. It is a conic section and is defined as the locus of points equidistant from a fixed point called the focus and a fixed line called the directrix

To find the equation of a parabola with the vertex at the origin (0, 0) and a focus at (-6, 0), we can use the standard form equation for a horizontally-oriented parabola:

(x - h)^2 = 4p(y - k)

where (h, k) represents the vertex coordinates, and p is the distance between the vertex and the focus.

In this case, the vertex is at (0, 0) and the focus is at (-6, 0). The distance between the vertex and focus is given by p = 6 (since the x-coordinate of the focus is 6 units away from the vertex).

Plugging these values into the standard form equation, we have:

(x - 0)^2 = 4(6)(y - 0)

Simplifying further, we get:

x^2 = 24y

Therefore, the equation of the parabola with the given vertex and focus is x^2 = 24y.

The arithmetic mean return is 3.6%, and the standard deviation is 2.14%.

To find the arithmetic mean, we add up the five returns and divide by the number of returns (in this case, 5):

(3% + 6% + 0% + 6% + 3%) / 5 = 3.6%

To find the standard deviation, we first need to find the variance. We can do this by taking each return, subtracting the mean return (3.6%), squaring the result, summing these values, and dividing by the number of returns minus 1 (4 in this case):

((3% - 3.6%)^2 + (6% - 3.6%)^2 + (0% - 3.6%)^2 + (6% - 3.6%)^2 + (3% - 3.6%)^2) / 4 = 0.046

The standard deviation is the square root of the variance:

√0.046 = 0.214 or 2.14%

Therefore, the arithmetic mean return for security y is 3.6%, and the standard deviation (sample) is 2.14%.

The chi-squared distribution is a continuous probability distribution that is often used in statistical hypothesis testing, especially in the field of the goodness of fit.

It is a distribution of the sum of squares of k independent standard normal random variables. The degree of freedom, k, determines the shape of the distribution.

The chi-squared distribution is frequently employed in hypothesis testing because of how closely it resembles the normal distribution. A test statistic, such as the t-statistic in a t-test, is used in many hypothesis tests.

The sampling distribution of the test statistic for these hypothesis tests approaches the normal distribution as the sample size, n, rises.

The distribution of real-world observations rarely has a chi-square shape. Chi-square distributions are primarily used for hypothesis testing rather than for characterizing actual distributions.
