The value of the independent variable probability is P ( A | B ) = 0.5

Given data ,

Let the independent events be represented as

P ( A ) = 0.5

P ( B ) = 0.15

Now , the value of the probability P ( A | B ) is given by

And , if events A and B are independent, then P(A|B) = P(A). Therefore, in this case, P(A|B) = P(A) = 0.5

Hence , the probability is P ( A | B ) = 0.5

Answer:

D = 10.3

Step-by-step explanation:

Distance Formula = √(x₂-x₁)² + (y₂-y₁)²

D = \(\sqrt{(-3-2)^2 + (-6-3)^2}\)

D = \(\sqrt{(-5)^2+(-9)^2}\)

D = \(\sqrt{25+81}\)

D = \(\sqrt{106}\)

D = 10.3

Therefore, the future value of a three-year uneven cash flow given below, using an 11% discount rate is $1,238.82.

To calculate the future value of a three-year uneven cash flow given below, using an 11% discount rate, we need to use the formula;

Future value of uneven cash flow = cash flow at year 1/(1+discount rate)¹ + cash flow at year 2/(1+discount rate)² + cash flow at year 3/(1+discount rate)³ + cash flow at year 4/(1+discount rate)⁴

Given the cash flows;

Year 0: $0

Year 1: $600

Year 2: $500

Year 3: $400

Then the Future value of uneven cash flow

= $600/(1+0.11)¹ + $500/(1+0.11)² + $400/(1+0.11)³

= $600/1.11 + $500/1.23 + $400/1.36

=$540.54 + $405.28 + $293.00

=$1,238.82

Therefore, the future value of a three-year uneven cash flow given below, using an 11% discount rate is $1,238.82.

Answer:

The answer is 17.

Step-by-step explanation:

Add 3 to both side:

10 = 2(r+1)^2

Divide both sides of the equation by 2:

5 = (r+1)^2

Take the square root of both sides:

√5 = r+1

Subtract 1 from both sides :

√5 - 1 = r

Answer:

x=-2,y=-4

Step-by-step explanation:

Substuting the value of y in second equation.

3x+3×2x=-18

9x=-18

x=-2

putting the value of x in equation 1 ,

y=-4

Step-by-step explanation:

y = 2x

so,

3x + 3y = -18

3(y÷2) + 3y = -18

3y ÷2 + 3y = -18

( 3y + 6y )÷2 = -18

9y ÷2 = -18

9y = -18 ×2

9y = -36

x = y÷2

The motion of the wagon linked to a wall with a spring and a damper is described by the differential equation \( m\frac{{d^2x}}{{dt^2}} + c\frac{{dx}}{{dt}} + kx = 0 \). which is the differential equation governing the motion of the wagon.

The motion of the wagon is governed by Newton's second law, which states that the sum of forces acting on an object is equal to its mass times its acceleration. Considering the forces acting on the wagon, we have the equation \( F_{\text{net}} = m\frac{{d^2x}}{{dt^2}} \), where \( m \) is the mass of the wagon.The forces acting on the wagon are the spring force (\( F_s = -kx \)) and the damping force (\( F_d = -c\frac{{dx}}{{dt}} \)). These forces oppose the motion of the wagon, leading to the negative signs. Combining the forces, we get \( m\frac{{d^2x}}{{dt^2}} + c\frac{{dx}}{{dt}} + kx = 0 \)

The motion of the wagon linked to a wall with a spring and a damper is described by the differential equation \( m\frac{{d^2x}}{{dt^2}} + c\frac{{dx}}{{dt}} + kx = 0 \), where \( m \) is the mass of the wagon, \( c \) is the damping coefficient, \( k \) is the spring constant.

A SSS (side-side-side) theorem is kind of Congruence rule where two triangles with three congruent sides. So, we can solve it by showing the congruency between two triangles.

Statement: Side-Side-Side (SSS) ,the congruence theorem states that two triangles are congruent if three of their sides are equal to the corresponding sides of the other triangle.

Proof: Given, AB = DE, BC = EF, AC = DF.

To prove: ΔABC ≅ ΔDEF.

We know that the three sides of both triangles are equal in size and length. With both triangles superimposed, DE is placed on AB, EF is placed on BC, and DF is placed on AC. That is, AB = DE, BC = EF, AC = DF. Therefore, we can say that ΔABC ≅ ΔDEF.

The velocity of the cylinder when it reaches the bottom of the incline is v = sqrt(4gh/3).

The velocity of the cylinder when it reaches the bottom of the incline can be calculated using the principle of conservation of energy. The velocity of the cylinder is given by the formula v = sqrt(2gh/(1+I/(mr^2))), where g is the acceleration due to gravity, h is the height of the incline, and I is the moment of inertia of the cylinder.

In this case, the cylinder is released from rest at a height h on an incline without slipping, which means that all the potential energy at the top of the incline is converted to kinetic energy at the bottom of the incline. Therefore, we can write:

1/2 mv^2 = mgh

where v is the velocity of the cylinder at the bottom of the incline.

The moment of inertia of the cylinder is given as 1/2mr^2. Substituting this into the formula for v and simplifying, we get:

v = sqrt(2gh/(1+1/2)) = sqrt(4gh/3)

Therefore, the velocity of the cylinder when it reaches the bottom of the incline is v = sqrt(4gh/3).

68% of the races he competed in had a finish time around 64.5 and 65.5 seconds.

The term "variance" (or "") refers to an assessment of the data's dispersion from the mean. A small variance implies that the data are grouped around the normal, and while a large standard deviation shows that the data are more dispersed.

\(\begin{aligned}& \mathrm{P}(\mu-\sigma < \mathrm{X} < \mu+\sigma) \approx 68 \% \\& \mathrm{P}(\mu-2 \sigma < \mathrm{X} < \mu+2 \sigma) \approx 95 \% \\& \mathrm{P}(\mu-3 \sigma < \mathrm{X} < \mu+3 \sigma) \approx 99.7 \%\end{aligned}\)

When the standard deviation out from mean of the distribution of X is and the mean of the dispersion of X is (assuming X is normally distributed).

Kiran's 400-meter dash timings have an average of 65 secs and a confidence interval of 0.5 seconds, and they are regularly distributed.

Using the formula, we then obtain

\(\mathrm{P}(65-0.5 < \mathrm{X} < 65+0.5)=\mathrm{P}(64.5 < \mathrm{X} < 65.5) \approx 68 \%\)

The shortest length of fence that the rancher can use is 6000 ft.

What is meant by length?

The measuring of one thing from finish to finish or on its longest aspect, or a measuring of a selected a part of one thing is known as length.

Main Body:

x = width of rectangle

y = length of rectangle

A = area of rectangle = xy = 1500000 ft^2

L = length of fencing needed = 2(x + y) + x = 3x + 2y

L = 3x + 2(1500000/x) = 3x + 3(10^6)x^(-1)

As x –> 0+, L –> +inf.

As x –> +inf, L –> (3x)+.

Sketch and see that there will be a minimum in Quadrant I.

dL/dx = 3 - 3(10^6)x^(-2)

Extrema occur when dL/dx = 0:

3 - 3(10^6)x^(-2) = 0

(10^6)x^(-2) = 1

x^2 = 10^6

x > 0, so x = 1000 feet for shortest length.
