The value of P(A | B) is a) 0.4878.

We have been given the following information:

A and B are events in a sample space S such that P(A) = 0.38, P(B) = 0.41, and P(A ∩ B) = 0.20.

We need to find P(A | B), which represents the probability of event A occurring given that event B has occurred.

The conditional probability formula states that P(A | B) = P(A ∩ B) / P(B).

By substituting the given values, we can calculate:

P(A | B) = 0.20 / 0.41 ≈ 0.4878.

Therefore, the value of P(A | B) is approximately 0.4878, which corresponds to option (a).

Hence, option (a) is correct.

In given word problem Andre has more money than Elena after four weeks.

What is word problem?

A math word problem is a question that is written as one or more sentences and asks students to use their mathematical understanding to solve an issue from "real world." In order to understand the word problem, they must be familiar with the terminology that goes along with the mathematical symbols that they are used to.

Here,

Initial investment of Andre= $50

She add $5 per week for next 4 weeks , then

=> 4×5 = $20

Then total savings of Andre = $50+$20=$70.

Now Initial investment of Elena = $5

She adds $10 for each 4 weeks then

=> 10×4=$40.

Now total savings of Elena = $40+$5=$45.

Here $70>$45.

Hence after 4 weeks Andre has more money than Elena.

The crew's rowing rate in still water is 13 km/h.

Let's assume the rowing rate of the boat in still water is denoted as "b" km/h, and the speed of the current is denoted as "c" km/h.

When the boat is rowing downstream, it benefits from the current, which increases its effective speed. The effective speed is calculated by adding the rowing rate in still water to the speed of the current:

Effective speed downstream = b + c

According to the given information, the boat covered 180 kilometers downstream in 9 hours. Therefore, we have the equation:

180 = (b + c) * 9

Simplifying the equation, we have:

(b + c) = 20 (Equation 1)

When the boat is rowing upstream, it has to overcome the current, which reduces its effective speed. The effective speed upstream is calculated by subtracting the speed of the current from the rowing rate in still water:

Effective speed upstream = b - c

Again, according to the given information, the boat covered 180 kilometers upstream in 30 hours. Therefore, we have the equation:

180 = (b - c) * 30

Simplifying the equation, we have:

(b - c) = 6 (Equation 2)

To find the crew's rowing rate in still water, we can solve the system of equations formed by Equations 1 and 2.

Adding Equation 1 and Equation 2:

(b + c) + (b - c) = 20 + 6

2b = 26

Dividing both sides by 2:

b = 13

Hence, the crew's rowing rate in still water is 13 km/h.

If 79% of the participants played pickleball, then 21% of the participants do not play pickleball.

Input these percentages into the table:

\(\begin{array}{|l|c|c|c|}\cline{1-4} \vphantom{\dfrac12}& \sf Male & \sf Female & \sf Total\\\cline{1-4} \vphantom{\dfrac12}\sf Plays \; pickleball & & & 79\%\\\cline{1-4} \vphantom{\dfrac12}\sf Does\;not\;play\; pickleball & & & 21\%\\\cline{1-4} \vphantom{\dfrac12}\sf Column\;Totals&&& 100\%\\\cline{1-4}\end{array}\)

Of those who play pickleball, 6% are female.

Therefore, of those who play pickleball, 94% must be male.

The total percentage of those who play pickleball is 79%, so find 6% and 94% of 79%:

\(\begin{aligned}\textsf{Plays pickleball (female)}&=6\% \; \sf of \; 79\%\\&=0.06 \times 0.79\\&=0.0474\\&=5\%\; \sf (nearest\;percent)\end{aligned}\)

Of those who do not play pickleball, 21% are male.

Therefore, of those who do not play pickleball, 79% must be female.

The total percentage of those who do not play pickleball is 21%, so find 21% and 79% of 21%:

\(\begin{aligned}\textsf{Does not play pickleball (male)}&=21\% \; \sf of \; 21\%\\&=0.21 \times 0.21 \\&=0.0441\\&=4\%\; \sf (nearest\;percent)\end{aligned}\)

Answer:

1.Corresponding angles theorem

2.Linear postulate

3.By the definition of supplementary angles

Step-by-step explanation:

We are given that  

\(w\parallel x \ and \ y\) is a transversal.

We have to prove \(\angle 3\) and \(\angle 5\) are supplementary

Proof:

1.Given that \(w\parallel x \ and \ y\) is a transversal.

We know that \(\angle 1\cong \angle 5\)

Reason:Corresponding angles theorem

Therefore, \(m\angle 1=m\angle 5\)

by the definition of congruent.We also know that, by definition, angle 3 and angle 1 are a linear pair.

Therefore, they are supplementary by linear pair postulate

By the definition of supplementary angles

\(m\angle 3+m\angle 1=180^{\circ}\)

Now, we can substitute \(m\angle 5=m\angle 1\)

Then, we get

\(\m\angle 3+m\angle 5=180^{\circ}\)

Therefore, by the definition of supplementary angles,angle 3 and angle 5 are supplementary

Answer:

1. Corresponding angles theorem

2. Linear pair postulate

Depending on whether the movement is along the x-axis or the y-axis, the ordered pair would be either (0.25, 0) or (0, 0.25).

To plot an ordered pair starting from the origin and moving 0.25, we need both an x-coordinate and a y-coordinate.

We are starting from the origin (0, 0), we can apply the movement of 0.25 to either the x-axis or the y-axis.

If we move 0.25 units on the x-axis, the x-coordinate of the ordered pair would be 0.25, and the y-coordinate would remain 0 since there is no movement on the y-axis. Therefore, the ordered pair would be (0.25, 0).

Similarly, if we move 0.25 units on the y-axis, the x-coordinate would remain 0 since there is no movement on the x-axis, and the y-coordinate of the ordered pair would be 0.25. In this case, the ordered pair would be (0, 0.25).

So, depending on whether the movement is along the x-axis or the y-axis, the ordered pair would be either (0.25, 0) or (0, 0.25).

What is partial differential equation?

A partial differential equation (PDE) is an equation that involves partial derivatives of a multivariable function. It relates the function, its partial derivatives, and the independent variables. PDEs are used to describe various phenomena in physics, engineering, and other scientific fields, where the variables of interest depend on multiple independent variables. Solving PDEs involves finding a function that satisfies the equation and any given boundary or initial conditions.

To solve the partial differential equation \(∂w/∂t + ∂w/∂x = 0 \\\)with the initial conditions \(w(x,0) = x^2\) and w(0,t) = 5 using Laplace transform, we need to apply the Laplace transform operator to both sides of the equation and then solve for the transformed function.

Let's denote the Laplace transform of the function w(x,t) as W(x,s), where s is the complex frequency variable. Applying the Laplace transform to both sides of the equation, we get:

\(sW(x,s) - w(x,0) + ∂W(x,s)/∂x = 0\)

Using the initial condition \(w(x,0) = x^2\), we have:

\(sW(x,s) - x^2 + ∂W(x,s)/∂x = 0\)

Now, let's apply the Laplace transform to the boundary condition w(0,t) = 5:

W(0,s) = 5

We now have a transformed equation with the transformed function W(x,s) and transformed boundary condition W(0,s). To solve for W(x,s), we can integrate the equation with respect to x and solve the resulting ordinary differential equation. The solution for W(x,s) can then be inverse Laplace transformed to obtain the solution for w(x,t).

Please note that the specific solution depends on the domain and boundary conditions. Additional information or constraints may be required to determine a unique solution.

The explicit formula for the population growth is P(t) = 9 * (1 + 0.08)^t, where P(t) represents the population at time t, P0 is the initial population of 9, r is the growth rate of 8% or 0.08, and t is the time in years. Using this formula, we can calculate the population after 9 years which is approximately 16.03

To find the explicit formula for the population growth, we use the exponential growth model formula P(t) = P0 * (1 + r)^t. In this case, P0 is given as 9, and the growth rate r is 8%, or 0.08 when expressed as a decimal. Plugging these values into the formula, we get P(t) = 9 * (1 + 0.08)^t.

To evaluate the population after 9 years, we substitute t = 9 into the formula and calculate: P(9) = 9 * (1 + 0.08)^9. Using a calculator or performing the calculation manually, the population after 9 years is approximately 16.03 (rounded to two decimal places).

Therefore, the population after 9 years, based on the exponential growth model with an initial population of 9 and a growth rate of 8%, is approximately 16.03

Answer: $574

Step-by-step explanation:

First we need to calculate the price of the snowboard before the addition of the tax. This will be represented by x. Therefore,

6% of x = $32.50

0.06 × x = $32.50

0.06x = $32.50

x = $32.50 / 0.06

x = $541.67

Therefore, the total cost including the sales tax will be:

= $541.67 + $32.50

= $574.17

The amount that Dado will pay for 1 xylobar and 2 yakities is 1.779.

A mathematical equation is the statement that illustrates that the variables given. In this case, two or more components are taken into consideration to describe the scenario.

Zimak bought 3 xylobars and 5 from the intergalactic Candy. Let this be:

3x + 5y = 1.75

x = xylobars

y = yackities

Jeejuju paid 1.88 and got 4 xylobars and 1 yackity. Let this be:

4x + y = 1.88

Equate the equations and this will be:

4x + y = 1.88 ....... i

3x + 5y = 1.75 .... ii

From equation i y = 1.88 - 4x

Put this into equation ii

3x + 5y = 1.75

3x + 5(1.88 - 4x) = 1.75

3x + 9.4 - 30x = 1.75

Collect like terms

3x - 30x = 1.75 - 9.4

-27x = -7.65

Divide

x = 7.65 / 27

x = 0.283

xylobars = 0.283

Since 4x + y = 1.88

4(0.283) + y = 1.88

1.132 + y = 1.88

y = 1.88 - 1.132

y = 0.748

The cost for 1 xylobar and 2 yakities will be:

x + 2y

0.283 + 2(0.748)
