The probability that both will be married before the age of 18 is 0.0036. The probability that both will be married by the age of 25 is 0.25. Finally, the probability that both will be married by the age of 30 is 0.5476.

According to the brief report by NCHS, approximately 6% of women in the United States married for the first time before their 18th birthday, and 50% of women married by their 25th birthday. 74% of women married by their 30th birthday.The probability of a family with two daughters marrying at different ages is asked in the question. The probability that both daughters will be married by the ages of 18, 25, and 30 will be determined

The question requires finding the probability that both daughters of a family will be married by the ages of 18, 25, and 30 respectively. Since each daughter's wedding is a separate event, the individual probability of a daughter marrying at a given age will be determined separately and then multiplied together to get the probability of both daughters being married at the given age. So, let's find the probabilities of each daughter marrying at a given age:

Probability of one daughter getting married by 18 years:

As per the brief report, 6% of women in the United States married before the age of 18.

Therefore, the probability of one daughter getting married before the age of 18 is 0.06

Probability of one daughter getting married by 25 years:

As per the brief report, 50% of women in the United States get married by the age of 25. Therefore, the probability of one daughter getting married by 25 years is 0.5.

Probability of one daughter getting married by 30 years:

As per the brief report, 74% of women in the United States get married by the age of 30. Therefore, the probability of one daughter getting married by 30 years is 0.74.

The probability of both daughters getting married at the same age is the product of each daughter's probability of getting married at that age.

The probability that both daughters will get married before the age of 18 is:

P(both daughters married at 18 years) = P(daughter1 married at 18) × P(daughter2 married at 18)= 0.06 × 0.06= 0.0036

The probability that both daughters will get married by the age of 25 is:

P(both daughters married at 25 years) = P(daughter1 married at 25) × P(daughter2 married at 25)= 0.5 × 0.5= 0.25

The probability that both daughters will get married by the age of 30 is:

P(both daughters married at 30 years) = P(daughter1 married at 30) × P(daughter2 married at 30)= 0.74 × 0.74= 0.5476

The probability that in a family with two daughters, both will be married before the age of 18 is 0.0036. The probability that both daughters will be married by the age of 25 is 0.25. Finally, the probability that both daughters will be married by the age of 30 is 0.5476.

Answer:

0 = 7x-6y -99

Step-by-step explanation:

The slope intercept form of a line is

y = mx+b where m is the slope and b is the y intercept

y = 7/6x+b

Using the point

-6 = 7/6(9) +b

-6 = 7*3/2 +b

-6 = 21/2 +b

Subtract 21/2 from each side

-12/2 -21/2 = b

-33/2 = b

y= 7/6x -33/2

Multiply each side by 6

6y = 7x - 99

Subtract 6y from each side

0 = 7x-6y -99

Answer:

a = -3

Step-by-step explanation:

Step 1:  Since we're told that 5 to the power of a = 1/125, we can use the following equation to solve for a:

5^a = 1/125

Step 2:  Take the log of both sides

log(5^a) = log(1/125)

Step 3:  According to the power rule of logs, we can bring a down and multiply it by log(5):

a * log(5) = log (1/125)

Step 4:  Divide both sides by log(5) to solve for a:

(a * log(5) = log(1/125)) / log(5)

a = -3

Optional 5:  We can check our answer by plugging in -3 for a and seeing if we get 1/125 when completing the operation:

5^-3 = 1/125

1/(5^3) = 1/125 (rule of exponents states that a negative exponent creates a fraction with 1 as the numerator and the base (5) and exponent (-3 becoming 3) as the denominator

1/125 = 1/125

Parabolic CoordinatesParabolic coordinates are a coordinate system that can be used to define any point in 2D Euclidean space.

In this system, points are defined by two variables u and v. The parabolic coordinates of a point in 2D Euclidean space can be found using the following equations: x = (u^2 - v^2) / 2y = uvIn this coordinate system, the differential unit of length, ds2, can be found using the equation:ds2 = du2 + dv2 + dx2where du2 and dv2 are the differentials of u and v, respectively, and dx2 is the differential of x. Cylindrical CoordinatesCylindrical coordinates are a coordinate system that can be used to define any point in 3D Euclidean space. In this system, points are defined by three variables r, θ, and z.

The cylindrical coordinates of a point in 3D Euclidean space can be found using the following equations: x = r cos(θ)y = r sin(θ)z = zIn this coordinate system, the differential unit of length, ds2, can be found using the equation:ds2 = dr2 + r2 dθ2 + dz2where dr2 and dθ2 are the differentials of r and θ, respectively, and dz2 is the differential of z. The volume element dV can be found using the equation:dV = r dr dθ dz. Using the above explanations, the differential unit of length, ds2, and the volume element dV for parabolic coordinates and cylindrical coordinates are as follows: For Parabolic Coordinates: ds2 = du2 + dv2 + dx2= du2 + dv2 + [(u2 - v2)/2]2dV = dudvdxdydz = [(u2 - v2)/2] dudvdzFor Cylindrical Coordinates: ds2 = dr2 + r2 dθ2 + dz2= dr2 + r2 dθ2 + dz2dV = rdrdθdzThe above explanations provide the main answer, which is the differential unit of length, ds2 and the volume element dV for parabolic coordinates and cylindrical coordinates.

$3000 is the ANSWER EDG 2022

Step-by-step explanation:

If DC = 10, the measure of DB is 20 units.

An equation to solve for x is 5x + 12 = 8x.

The measure of x is 4.

The measure of ∠BAC is 60°.

The measure of ∠B is 30°.

In Mathematics and Geometry, a perpendicular bisector is a line that bisects or divides a line segment exactly into two (2) equal halves and forms an angle that has a magnitude of 90 degrees at the point of intersection.

Therefore, the measure of DB can be calculated as follows;

DB = 2DC

DB = 2(10)

DB = 20 units.

Since the perpendicular bisector of DB is AC, an equation to solve for x is as follows;

5x + 12 = 8x

3x = 12

x = 12/3 = 4.

Since ∠D is congruent to ∠ABC, the measure of ∠BAC can be calculated as follows;

∠ABC + ∠BAC = 90° (complementary angles).

30° + ∠BAC = 90°

∠BAC = 90° - 30°

∠BAC = 60°

Similarly, ∠D is congruent to ∠B;

∠D ≅ ∠B = 30°.

Step-by-step explanat:

The area under the curve over [2,5] is 24.

Given function is f(x) = 2xIntervals [2, 5] is given and it is to be divided into subintervals.

Let us consider n subintervals. Therefore, width of each subinterval would be:

$$
\Delta x=\frac{b-a}{n}=\frac{5-2}{n}=\frac{3}{n}
$$Here, we are using right-hand end point. Therefore, the right-hand end points would be:$${ c }_{ k }=a+k\Delta x=2+k\cdot\frac{3}{n}=2+\frac{3k}{n}$$$$
\begin{aligned}
\therefore R &= \sum _{ k=1 }^{ n }{ f\left( { c }_{ k } \right) \Delta x } \\&=\sum _{ k=1 }^{ n }{ f\left( 2+\frac{3k}{n} \right) \cdot \frac{3}{n} }\\&=\sum _{ k=1 }^{ n }{ 2\cdot\left( 2+\frac{3k}{n} \right) \cdot \frac{3}{n} }\\&=\sum _{ k=1 }^{ n }{ \frac{12}{n}\cdot\left( 2+\frac{3k}{n} \right) }\\&=\sum _{ k=1 }^{ n }{ \frac{24}{n}+\frac{36k}{n^{ 2 }} }\\&=\frac{24}{n}\sum _{ k=1 }^{ n }{ 1 } +\frac{36}{n^{ 2 }}\sum _{ k=1 }^{ n }{ k } \\&= \frac{24n}{n}+\frac{36}{n^{ 2 }}\cdot\frac{n\left( n+1 \right)}{2}\\&= 24 + \frac{18\left( n+1 \right)}{n}
\end{aligned}
$$Take limit as n → ∞, so that $$
\begin{aligned}
A&=\lim _{ n\rightarrow \infty  }{ R } \\&= \lim _{ n\rightarrow \infty  }{ 24 + \frac{18\left( n+1 \right)}{n} } \\&= \boxed{24}

Given function f(x) = 2x. The interval is [2,5]. The number of subintervals, n is 3.

Therefore, the area under the curve over [2,5] is 21.

From the given data, we can see that the width of the interval is:

Δx = (5 - 2) / n

= 3/n

The endpoints of the subintervals are:

[2, 2 + Δx], [2 + Δx, 2 + 2Δx], [2 + 2Δx, 5]

Thus, the right endpoints of the subintervals are: 2 + Δx, 2 + 2Δx, 5

The formula for the Riemann sum is:

S = f(c1)Δx + f(c2)Δx + ... + f(cn)Δx

Here, we have to find a formula for the Riemann sum obtained by dividing the interval [2.5] subintervals and using the right hand endpoint for each ck. The width of each subinterval is:

Δx = (5 - 2) / n

= 3/n

Therefore,

Δx = 3/3

= 1

So, the subintervals are: [2, 3], [3, 4], [4, 5]

The right endpoints are:3, 4, 5. The formula for the Riemann sum is:

S = f(c1)Δx + f(c2)Δx + ... + f(cn)Δx

Here, Δx is 1, f(x) is 2x

∴ f(c1) = 2(3)

= 6,

f(c2) = 2(4)

= 8, and

f(c3) = 2(5)

= 10

∴ S = f(c1)Δx + f(c2)Δx + f(c3)Δx

= 6(1) + 8(1) + 10(1)

= 6 + 8 + 10

= 24

Therefore, the Riemann sum is 24.

To calculate the area under the curve over [2, 5], we take the limit of the Riemann sum as n → ∞.

∴ Area = ∫2^5f(x)dx

= ∫2^52xdx

= [x^2]2^5

= 25 - 4

= 21

Therefore, the area under the curve over [2,5] is 21.

Step 1: 3x + 2 - 4x Distributive Property: The distributive property is used to multiply the 2 by the 4x, resulting in 8x.

The distributive property is a rule of mathematics that states that when you multiply a number by the sum of two other numbers, the result is the same as if you had multiplied the number by each of the two numbers separately and then added the results together. This property is also known as the distributive law of multiplication over addition. For example, if you are asked to multiply 3 x (2 + 5), you can use the distributive property to calculate it as 3 x 2 + 3 x 5, which equals 6 + 15, or 21.

Step 2: 3x + 8x, Combine Like Terms: The like terms of 3x and 8x are combined, resulting in 11x.

Step-by-step explanation:

We can use the Pythagorean theorem since this is a right triangle:

a^2+ b^2 = c^2 where a and b are the legs and c is the hypotenuse

a=6 and b = 10

6^2 + b ^2 = 10^2

36+ b^2 = 100

b^2 = 100-36

b^2 = 64

Taking the square root of each side

sqrt(b^2) = sqrt(64)

b = 8

The correct choice is: B. There is a unique solution in the region consisting of all points in the xy-plane except the origin.

To determine the region of the xy-plane for which the given differential equation, x(dy/dx) = y, would have a unique solution passing through a point (x0, y0) in the region, we can analyze the characteristics of the equation.

The given differential equation is a first-order linear ordinary differential equation. It can be rearranged as (dy/dx) = (y/x).

The general solution of this differential equation is y = Cx, where C is a constant.

To have a unique solution passing through a specific point (x0, y0), the constant C must be uniquely determined. In other words, there should not be multiple values of C that satisfy the condition.

Let's analyze the options:

A. There is a unique solution in the entire xy-plane.

This statement is incorrect. The equation y = Cx represents a family of lines passing through the origin (0, 0), and different values of C will give different lines.

B. There is a unique solution in the region consisting of all points in the xy-plane except the origin.

This statement is correct. Excluding the origin (0, 0), each point in the xy-plane corresponds to a unique value of C, resulting in a unique solution.

C. There is a unique solution in the region x < 1.

This statement is incorrect. The region x < 1 includes points where x = 0, which leads to an undefined solution (division by zero) for the given differential equation.

D. There is a unique solution in the region y ≤ x.

This statement is incorrect. The region y ≤ x includes the origin (0, 0), and as mentioned earlier, the equation y = Cx does not provide a unique solution passing through the origin.

E. There is a unique solution in the regions x > 0 and x < 0.

This statement is correct. For x > 0 and x < 0, each region corresponds to a unique value of C, resulting in a unique solution passing through the respective regions.

Based on the analysis, the correct choice is: B. There is a unique solution in the region consisting of all points in the xy-plane except the origin.
