None of the chosen pairs will be dependent as nothing is specified.

Independent events are those events whose occurrence does not have any effect on the events that may occur or occurred.

Dependent events are those vents whose occurrence either depends on some other event or has an effect on occurring or occurred vents.

Answer:

To solve this problem, we will use the following steps:

Step 1: Let's assume that the larger number is x and the smaller number is y, we know that the difference between the two numbers is 9, so we can write the equation: x-y = 9

Step 2: We know that Four times the larger number plus one-half the smaller is 45, so we can write the equation: 4x + 0.5y = 45

Step 3: Now we have two equations with two unknowns, we can solve for one of the unknowns by isolating it in one of the equations.

x-y = 9

x = y+9

Step 4: Now we can substitute the value of x in the second equation

4(y+9) + 0.5y = 45

4y + 36 + 0.5y = 45

4.5y + 36 = 45

4.5y = 9

y=2

Step 5: We can substitute the value of y in one of the equation, to find the value of x

x-2 = 9

x = 11

Final Answer: The two numbers are 11 and 2.

Event a has a 12/25 chance of happening provided that event b has already happened.

It is stated as a number between 0 and 1, where 0 denotes that the event is hypothetical and 1 denotes that it is unavoidable. Furthermore, probability can be stated as a percentage, with a range of 0% to 100%. By dividing the number of favourable outcomes by the entire number of possible possibilities, the probability of an event is determined. Many disciplines, such as statistics, economics, and physics, among others, utilise probability theory.

given

We may apply the conditional probability formula to determine p(a/b):

p(a and b) / p = p(a and b) (b)

Given that p(b) = 1/4 and p(a and b) = 3/25, we may enter these numbers in the formula as follows:

p(a/b) = (3/25) / (1/4)

p(a/b) = (3/25) * (4/1)

p(a/b) = 12/25

Event a has a 12/25 chance of happening provided that event b has already happened.

Answer:

10,000 I think.

Step-by-step explanation:

10 x 1000. Put the 0 at the back. So it has 4 zero and so you put the zero at the back and what is 1 x 1 well it's 1, so it's 10,000. I think.

Recall that

\((a+b)^3=a^3+3a^2b+3ab^2+b^3\)

which means

\(\left(r+\dfrac1r\right)^3=r^3+3r^2\left(\dfrac1r\right)+3r\left(\dfrac1r\right)^2+\left(\dfrac1r\right)^3=r^3+3r+\dfrac3r+\dfrac1{r^3}\)

Given that \(r+\frac1r=\sqrt2\), we have

\((\sqrt2)^3=r^3+3\sqrt2+\dfrac1{r^3}\)

\(\implies r^3+\dfrac1{r^3}=2\sqrt2-3\sqrt2=\boxed{-\sqrt2}\)

The domain value that corresponds to a range value of 4 is,

⇒ x = 1/2

Given that;

Function is,

y = 4x + 2

Since, the equation equal to the range value:

4 = 4x + 2

Then, we can solve for "x":

4 - 2 = 4x

2 = 4x

x = 1/2

Now that we have the value of "x", we can find the corresponding value of "y" by substituting it into the given equation:

y = 4x + 2

y = 4(1/2) + 2

y = 4 + 2

y = 6

Therefore, the domain value that corresponds to a range value of 4 is,

Answer:

Step-by-step explanation:

The given proof is correct. Here is a step-by-step explanation of the proof:

It is given that ∠EIJ ≅ ∠GJI.

∠EIJ ≅ ∠IKL and ∠GJI ≅ ∠JLK, as they are corresponding angles for parallel lines cut by a transversal.

By the definition of congruent angles, m∠EIJ = m∠GJI, m∠EIJ = m∠IKL, and m∠GJI = m∠JLK.

So, m∠IKL = m∠JLK by the Transitive Property of Equality.

Angle JLK and ∠JLD are supplementary angles by the definition of supplementary angles, so m∠JLK + m∠JLD = 180°.

By the Substitution Property of Equality, m∠IKL + m∠JLD = 180°.

Therefore, ∠IKL and ∠JLD are supplementary angles by definition.

Hence, the proof is complete.

The amount that Guillermo will pay monthly to keep his home insurance is $270.83.

An insurance premium is a charge that the insurer demands from the insured periodically as part of the pooling of risks under an insurance contract.

House value = $625,000

Insurance premium rate = $0.52 per $100

Annual premium = $3,250 ($625,000 x $0.52/$100)

Monthly premium = $270.83 ($3,250/12)

Thus, the amount that Guillermo will pay monthly to keep his home insurance is $270.83.

Answer: slope is 3, y-intercept is 2

Step-by-step explanation:

The slope of a line is the ratio at which the y value changes with respect to the x value. Since the entire line is straight, the slope at every single point along the line is the exact same. This means that we can find the slope at any point along the line and it'll represent the slope for the entire line.

When x = 0, the y = 2. Therefore we have the point, (0, 2). When x = 1, the y value is y = 5. Therefore, we have another point, (1, 5). The difference between the y values is:

\(5-2=3\)

The difference between the x values is:

\(1-0=1\)

Therefore, their ratio is:

\(3/1=3\)

The y-intercept is the y value at which the function intercepts the y-axis. That would be when y = 2

The side length of the cube is 5.6 feet (rounded to the nearest tenth).

We can calculate the side length of a cube with a volume of 141 cubic feet using the formula for cube volume , which is \(V = s^3\), where V is the volume and s is the side length.

We can calculate s by taking the cube root of both sides of the equation:

\(s = (V)^{(1/3)\)

Substituting V = 141, we get:

\(s = (141)^{(1/3)\)

By using a calculator to evaluate this expression, we may determine:

s ≈ 5.6

As a result, the cube's side length is roughly 5.6 feet (rounded to the closest tenth). This indicates that if we increase the side length by three, it will become longer. (\(s^3\)), we will get the volume of the cube, which is 141 cubic feet.

The total weight of the liquid in the tank is approximately 12,628 pounds.

To calculate the weight of the liquid, we need to determine the volume of the hemisphere and then multiply it by the density of the liquid. The formula for the volume of a hemisphere is V = (2/3)πr³, where r is the radius of the hemisphere.

In this case, the diameter of the tank is given as 24 feet, so the radius is half of that, which is 12 feet. Plugging this value into the formula, we get V = (2/3)π(12)³ ≈ 904.78 cubic feet.

Finally, we multiply the volume by the density of the liquid: 904.78 cubic feet * 92.5 pounds per cubic foot ≈ 12,628 pounds. Therefore, the total weight of the liquid in the tank is approximately 12,628 pounds.

In summary, to calculate the weight of the liquid in the tank, we first determine the volume of the hemisphere using the formula V = (2/3)πr³. Then, we multiply the volume by the density of the liquid.

By substituting the given diameter of 24 feet and using the appropriate conversions, we find that the total weight of the liquid is approximately 12,628 pounds.
