Let X >0 denote a random variable with p.d.f. fx(2) and c.d.f. Fx (I). Assume Fx() is monotone increasing, and let Y = FX(X). That is, Y is a random variable that takes the value Fx (1) when X = r. Find fy(y). Mark the correct answer (a) fy(y) = 1,0

Answers

The probability density function (PDF) of Y can be determined by the transformation of the PDF of X. Using the transformation rule, we can calculate that fy(y) = fx(x) |dx/dy|, where x is a function of y, since y = Fx(x).

We can use the Chain Rule to determine the derivative of x with respect to y. Since Fx is a monotone increasing function, dx/dy = 1/F'x(x). Substituting this into the transformation rule, fy(y) = fx(x) / F'x(x).

Therefore, to find fy(y), we need to calculate F'x(x). Fx is the cumulative distribution function, which means that its derivative F'x(x) is the probability density function of X, or fx(x). Substituting this into the transformation rule, fy(y) = fx(x) / fx(x). Since fx(x) = fx(2) and fx(2) is a constant, fy(y) = 1/fx(2).

To summarize, the probability density function of Y is given by fy(y) = 1/fx(2).

Consider the following equation
-16p + 37 = 49 - 21p

Answers

the solution to the equation -16p + 37 = 49 - 21p is p = 12/5. The equation -16p + 37 = 49 - 21p is a simple linear equation with one variable, p.

Linear equations are equations where the highest exponent of the variable is one, and they can be solved using algebraic techniques.

To solve this equation, we need to isolate the variable, p, on one side of the equation. We can start by simplifying the equation by combining like terms. To do this, we can add 21p to both sides of the equation, which gives us:

-16p + 37 + 21p = 49

Next, we can combine the terms -16p and 21p, which gives us 5p. So, the equation becomes:

5p + 37 = 49

We can further simplify the equation by subtracting 37 from both sides, which gives us:

5p = 12

Finally, we can solve for p by dividing both sides of the equation by 5:

p = 12/5

So, the solution to the equation -16p + 37 = 49 - 21p is p = 12/5.

In summary, the given equation is a simple linear equation that can be solved using algebraic techniques. We can isolate the variable, p, on one side of the equation by combining like terms and simplifying the equation. Finally, we can solve for p by dividing both sides of the equation by the coefficient of p.

Write your answer using decimals, if necessary. Square millimeters

Answers

Based on the given data, The shape's whole surface area is about 252 mm².

Based on the image, the shape appears to be a set of rectangles with different lengths and widths.

To find the area of this shape, we can break it down into smaller rectangles and add up their areas.

Starting from the bottom, we can see that the first rectangle has a length of 6 mm and a width of 4 mm. Its area is:

Area1

= 6 mm × 4 mm

= 24 mm²

Moving up to the second rectangle, we see that it has a length of 6 mm and a width of 3 mm. Its area is:

Area2

= 6 mm × 3 mm

= 18 mm²

The third rectangle has a length of 6 mm and a width of 5 mm. Its area is:

Area3

= 6 mm × 5 mm

= 30 mm²

The fourth rectangle has a length of 6 mm and a width of 3 mm. Its area is:

Area4

= 6 mm × 3 mm

= 18 mm²

The fifth rectangle has a length of 6 mm and a width of 15 mm. Its area is:

Area5

= 6 mm × 15 mm

= 90 mm²

The sixth rectangle has a length of 3 mm and a width of 9 mm. Its area is:

Area6

= 3 mm × 9 mm

= 27 mm²

Finally, the seventh rectangle has a length of 5 mm and a width of 9 mm. Its area is:

Area7

= 5 mm × 9 mm

= 45 mm²

To find the total area of the shape, we can add up the areas of all seven rectangles:

Total Area

= Area1 + Area2 + Area3 + Area4 + Area5 + Area6 + Area7

= 24 mm² + 18 mm² + 30 mm² + 18 mm² + 90 mm² + 27 mm² + 45 mm²

= 252 mm²

Therefore, the total area of the shape is approximately 252 mm².

Answers

Leo has 38 toy troops as there aren't enough for him to line them up four by four.

what is equation ?

The equal symbol (=) is frequently used to separate the expressions in equations. The left-hand side (LHS) and right-hand side (RHS) of the equation, respectively, are the formulas on either side of the equal sign. If you replace the variable(s) in both expressions with the same value, they will have the same value, as indicated by the equal symbol, which denotes that the two sides are equivalent.

given

We'll name Leo's collection of toy soldiers "x" the amount.

Finally, we know that the remainder is 3 when x is split by 5. Thus, x Plus 2 must be a multiple of 5.

Using this knowledge, we can construct the following system of equations:

x = 4n (where n is a positive number) (where n is a positive integer)

x + 1 = 7m (where m is a positive number) (where m is a positive integer)

x + 2 = 5p (where p is a positive number) (where p is a positive integer)

Testing different values of x that meet these two requirements reveals that x = 38 is the only answer that also resolves the second problem.

False. A probability distribution for a discrete variable is not exclusive, collectively exhaustive list of numerical outcomes for that variable and the probability of occurrence associated with each outcome.

A probability distribution for a discrete variable is a list of all possible values that the variable can take on, along with the probability of each value occurring. The values must be collectively exhaustive (meaning they include all possible outcomes) and mutually exclusive (meaning that each outcome cannot occur at the same time as any other outcome). However, the numerical outcomes do not have to be exclusive, as they can have the same probability of occurring. For example, a coin toss has two possible outcomes (heads and tails) with equal probability, and a dice roll has six possible outcomes with equal probability.

Answers

1) Option a. Depreciation expenses of $6,710 will be recorded each year. is correct.

2) Option c. 175,000 × 7.99% is correct

3) Option b. $105,000 is correct.

1) The annual payments of $10,000 and the recorded cost of the asset of $67,100 are used to calculate the annual depreciation expense using the straight-line method.

Depreciation expense = (Recorded cost of the asset - Residual value) / Useful life

= ($67,100 - $0) / 10 years

= $6,710 per year.

2) The effective interest method calculates interest expense by multiplying the carrying value of the bond (i.e., the amount at which it was issued minus any discount or plus any premium) by the effective interest rate (i.e., the rate that discounts the bond's future cash flows to the carrying value).

Therefore, the interest expense for the first year on the bonds would be $175,000 × 7.99% = $13,965.

3) The dividends declared during the year can be calculated as follows:

Dividends declared = Net income - Increase in retained earnings - Decrease in dividends payable

= $150,000 - ($345,000 - $300,000) - ($29,000 - $19,000)

= $105,000.

For the given system of linear inequalities (53, 4) represents 53 batches of soap and 4 batches of lotion were produced.

What is linear inequality?

An equation with a linear expression and a relational operator is referred to as a linear inequality. Regions in a coordinate plane or space that fulfil a linear inequality are defined by the inequality. A linear inequality in two dimensions defines a half-plane, which, depending on the inequality, is either above or below a line. A linear inequality in three dimensions defines a half-space that, depending on the inequality, is either above or below a plane. In optimization situations, when the objective is to determine the greatest or lowest value of a linear function under a set of constraints represented by linear inequalities, linear inequalities are frequently utilised.

The given system of inequalities is:

5x + 15y ≤ 325

20x + 35y ≤ 1200

Answers

Te surface area of the smaller figure based on the ratio is 1600m²

Calculating the surface area of the smaller figure.

The ratio of the volumes of two similar figures is equal to the cube of the ratio of their corresponding sides.

Let x be the scale factor between the smaller and larger figures.

Then we have:

(x³)/(4000) = 6912

x³ = 6912/4000

x³ = 1.728

Taking the cube root of both sides, we get:

x = 1.2

So the scale factor from the larger figure to the smaller figure is 1:1.2.

The surface area of a similar figure is proportional to the square of the scale factor.

So we can use the scale factor to find the ratio of the surface areas:

SA(smaller) / SA(larger) = 1/(1.2)²

We know that the surface area of the larger figure is 2304m^2, so we can solve for the surface area of the smaller figure:

SA(smaller) = 2304 * 1/(1.2)²

SA(smaller) = 1600m²

Answers

The rate of change of an edge of the cube is approximately 0.048 m/min when the volume is exactly 27 cubic meters.

To find the rate of change of an edge of the cube, given that the volume decreases at a rate of 4 cubic meters per minute when the volume is exactly 27 cubic meters, follow the solution below:Let the length of the edge of the original cube be L.Let the volume of the original cube be V, such that V = L³.The rate of change of volume is given as -4 m³/min; the negative sign is used to indicate a decrease in volume, and this is obtained when the derivative of the volume with respect to time is multiplied by the negative sign.Let V₀ be the original volume of the cube, and V₁ be the volume after t minutes. Thus, V₁ = V₀ - 4t m³. We are told that V₁ = 27 m³, hence:V₀ - 4t = 27 ⇒ V₀ = 27 + 4t m³Substituting V₀ in terms of t into the expression V = L³, we have:L³ = 27 + 4tTaking the derivative of both sides with respect to t, we have:3L²(dL/dt) = 4 ⇒ dL/dt = 4/(3L²)Substituting L from the expression L³ = 27 + 4t, we have:L = (27 + 4t)^(1/3)Therefore, the rate of change of an edge of the cube is given by the derivative of L with respect to t:dL/dt = 4/(3L²) = 4/(3(27 + 4t)^2/3) ≈ 0.048 m/min (to 3 decimal places)Answer: The rate of change of an edge of the cube is approximately 0.048 m/min when the volume is exactly 27 cubic meters.

Answers

The cumulative distributive function (CDF) Fx(3) is 0.61.

The cumulative distributive function (CDF) of a random variable X is the probability that X takes a value less than or equal to x. In this case, we are asked to find Fx(3).

Since the random variable X is given with a probability mass function, we can calculate the CDF by summing the probabilities of X being less than or equal to 3. This can be expressed as: [tex]Fx(3) = P(X<=3).[/tex]
For X = 0, P(X<=3) = 0.23.
For X = 1, P(X<=3) = 0.23 + 0.13 = 0.36.
For X = 2, P(X<=3) = 0.23 + 0.13 + 0.10 = 0.46.
For X = 3, P(X<=3) = 0.23 + 0.13 + 0.10 + 0.15 = 0.61.

Therefore, the cumulative distributive function (CDF) Fx(3) is 0.61.

Statistics question : what was done to get the values in red ? (The ones inside the table based on the question )

Answers

Given that he is from the Dominican Republic, the likelihood that the chosen player is a pitcher is roughly 0.053.

what is probability ?

The study of arbitrary events or experiments falls under the purview of probability, a subfield of mathematics. A value between 0 (impossible) and 1 is used to estimate the possibility or chance of an event occurring (certain). Several disciplines, including science, engineering, economics, finance, and more, utilise the idea of probability. It is frequently determined by dividing the number of positive events by the total number of outcomes that could occur.

given

(a) To find P, we can utilize the complement rule (T&D). The addition to T&D is the possibility that the chosen player is a pitcher or a Dominican. We thus have:

The equation P(T&D) = 1 - P(T'UD') = 1 - P(T') - P(D') + P(T'D')

P(T), P(D), and P(TD) are all provided as 0.42, 0.105, and 0.056 respectively. As a result, we may determine the complements' probabilities:

P(T') = 1 - P(T) = 1 - 0.42 = 0.58 P(D') = 1 - P(D) = 1 - 0.105 = 0.895 P(T'D') = P(TD)' = 1 - (P(T) + P(D) - P(TD)) = 1 - (0.471 + 0.42 + 0.105 - 0.056)

By replacing these values, we obtain:

P(T&D) = 1 - 0.58 - 0.895 + 0.471 = 0.046

As a result, there is a 0.046 percent chance that the chosen player is a non-pitcher from outside the Dominican Republic.

(b) In order to determine the likelihood that the chosen player is a pitcher given that he is from the Dominican Republic, we must first determine P(P|D). Bayes' Theorem may be applied:

P(P|D) equals P(D|P)P(P)/P (D)

P(D) = 0.105 and P(TD) = 0.056 are the values provided. Therefore,

P(P) is defined as P(TD') / P(D') = 0.056 / 0.895 0.0626.

P(D|P) is equal to P(T|D) / P(P) = 0.056 / 0.0626 0.895.

By replacing these values, we obtain:

P(P|D) = (0.895)(0.0626) / 0.105 ≈ 0.053

Given that he is from the Dominican Republic, the likelihood that the chosen player is a pitcher is roughly 0.053.

Use substitution to solve -4x + y = 3, 5x - 2y = -9

Answers

Using  the substitution method, the solution of the system of equations -4x + y = 3 and 5x - 2y = -9 is (x, y) = (1, 7)

We can solve this system of equations using the substitution method by solving for one variable in terms of the other in one equation, and then substituting that expression into the other equation. Here's how:

-4x + y = 3 (Equation 1)

5x - 2y = -9 (Equation 2)

Solving Equation 1 for y, we get:

y = 4x + 3

Now, we substitute this expression for y into Equation 2 and solve for x:

5x - 2(4x + 3) = -9

5x - 8x - 6 = -9

-3x = -3

x = 1

We have found the value of x to be 1. Now, we substitute this value back into Equation 1 to find the value of y:

-4(1) + y = 3

y = 7

Therefore, the solution to the system of equations is (x, y) = (1, 7)

The selling price of a table is ₹ 5400.If the shopkeeper makes a profit of 20%, find the cost
price of the table?

Answers

Sure! I can help you with that.

First, we should calculate the profit made by the shopkeeper. To calculate the profit, we will multiply the selling price of the table with 20%, which is 20% of 5400, or 1080.

Next, we should subtract the profit from the selling price to find the cost price of the table.

The cost price of the table = 5400 - 1080

The cost price of the table = 4320

Therefore, the cost price of the table is ₹ 4320.

At maxs party 3/12 of the guests are 10 year old and 7/12 of guests are 11 year old what fraction of the guests are 10 or 11 years old

Answers

The fraction of the guests are 10 or 11 years old is 5/6

A fraction represents a part of a whole, where the whole is divided into equal parts.

To find the fraction of guests who are 10 or 11 years old, we need to add the fractions of guests who are 10 years old and 11 years old.

3/12 of the guests are 10 years old, which can be simplified to 1/4.

7/12 of the guests are 11 years old.

Therefore, the fraction of guests who are 10 or 11 years old is

1/4 + 7/12 = 3/12 + 7/12

Add the fractions

= 10/12

Simplify the fraction

= 5/6

5. The contents of a sample of 26 cans of apple Juice showed a standard deviation of 0.06 ounces. we are interested in testing to determine whether the variance of the population is significantly more than 0.003. The alternative hypothesis is? a. S^2>0.003 b. S^2=0.003 c.sigma^2>0.003 d. sigma^2 = 0.003

Answers

The alternative hypothesis in this case is that the variance of the population is significantly greater than 0.003. Therefore, the correct answer is option A, S^2>0.003.

The variance is a term used in statistics that refers to how far the numbers in a data set are spread out. A set of numbers with a large variance has a wide distribution, while a set with a small variance has a narrow distribution.

The formula for the variance is as follows:S² = ∑(X - μ)² / Nwhere:∑ = the sum ofX = each individual data pointμ = the population meanN = the number of data points in the population. The null hypothesis in this case would be that the variance of the population is not significantly different from 0.003. The alternative hypothesis, on the other hand, is that the variance is significantly greater than 0.003. This is what option A suggests.

Answers

The numbers ordered from least to greatest are 0.721, 73/100, and 0.75.

0.75, 0.721, 73/100

we can convert the fraction 73/100 to a decimal by dividing 73 by 100, which gives us 0.73.

0.721 < 0.73 < 0.75

"Least" is a mathematical term used to refer to the smallest value in a given set of numbers or a range of values. It is the opposite of the term "greatest," which refers to the largest value in the set. To find the least value in a set of numbers, you can sort them in ascending order and select the first or smallest number. Alternatively, you can use mathematical formulas or functions such as the minimum function to determine the least value.

In algebra, finding the least common multiple (LCM) or least common denominator (LCD) involves identifying the smallest multiple or denominator that two or more numbers or expressions have in common. This is essential in simplifying and solving complex equations and expressions. In geometry, the least distance between two points is the straight line or path that connects them and is the shortest possible route between them. This concept is fundamental in navigation and optimization problems.

Given: AABC, measure of angle C=90°
AB = 8, measure of angle B=40°
Find: Perimeter of AABC

Answers

The perimeter of the triangle AABC is 19.27 m.

Solution:

In order to solve this we first have to create a triangle rectangle, check the image attached to understand it better, and with that we use law of sines in order to calculate the other sides of the triangle:

As you can see we know that the hypothenuse is 8 m, and we have both angles, so for the angle that is opposed to the 50º angle we will use [tex]8cos(50)=5.1423 \ m[/tex].

For the side that is opposed to the 40º angle we will use [tex]8cos(40):6.1283m[/tex]

SO to calculate the perimeter we just add the three sides:

[tex]5.1423 + 6.1283 + 8= 19.27[/tex]

Therefore, The perimeter of the triangle AABC is 19.27 m.
