In Bayes Theorem, | stands for 'given' or 'conditional on'. In bar charts, tend to summarize categorical type data. In Bayes Theorem, you have some starting information, then you collect some new information so that you can update the original probabilities so you now have better information.

In Bayes Theorem, the symbol | stands for 'given' or 'conditional on'. It is used to indicate that the probability is calculated under the condition that a certain event has occurred. For example, P(A|B) represents the probability of event A given that event B has occurred.

In bar charts, tend to summarize categorical type data. A bar chart is a type of graph that uses rectangular bars to represent data. Each bar in the chart represents a category, and the height of the bar represents the frequency or count of that category. Bar charts are useful for comparing the frequencies of different categories or showing the distribution of a single categorical variable.

In Bayes Theorem, you have some starting information, then you collect some new information so that you can update the original probabilities. This allows you to have better information and make more accurate predictions or decisions based on the new evidence.

If the linear dimensions of the cube double, the total electric flux through the cubic surface will double as well.

The total electric flux through a closed surface is equal to the charge enclosed within the surface divided by the permittivity of free space. The electric flux is given by the dot product of the electric field and the area vector of the surface, integrated over the surface.

When the linear dimensions of a cube double, the surface area of the cube increases by a factor of eight (2^3). This means that there is more surface area over which to integrate the electric flux, and therefore the total electric flux through the surface increases. However, the electric field inside the cube does not change when the dimensions double.

Therefore, the total electric flux through the surface increases as the cube's dimensions double, because there is more surface area over which to integrate the constant electric field. The increase in total electric flux is proportional to the increase in surface area, which is a factor of eight.

The area of the center section when the leaves are down is evaluated being of 932.84 in.²

If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:

\(|AC|^2 = |AB|^2 + |BC|^2\)

where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).

The simplified figure is attached below.

We need to find the area PQRS.

Area(PQRS) = 4(Area(DOQ) + Area(QOB)) (by symmetry.

The line OD and OT are perpendiculars on those 38 inch chords, and therefore D and T are bisecting them(by a theorem that perpendicular from center of a circle to its chords bisect them).

Using Pythagoras theorem, we get:
\(|DO| = \sqrt{|OQ|^2 -|DQ|^2 } = \sqrt{22^2 - 19^2} = \sqrt{123}\)

Thus, we get:

\(\text{Area DOQ} = \dfrac{1}{2} \times 19 \times \sqrt{123} \approx 105.36 \: \rm in^2\)

Since angle ∠DQO and ∠QOB are alternate interior angle, they are of same measure.

From triangle DOQ, from the perspective of ∠DQO, we get the sine ration as:

\(\sin(m\angle DQO) = \dfrac{|DO|}{|OQ|}\\m\angle DOQ = \sin^{-1}\left( \dfrac{\sqrt{123}}{22}\right) \approx 30.27^\circ \: \text{(chose acute angle)}\)

Thus, we get:
\(m\angle QOB \approx 30.27^\circ\)

360 degrees cover full area of circle,

1 degree will cover full area /360 of the circle

Thus, we get:

Aera of the sector QOB = Area covered by central angle ∠QOB\(\approx 30.27 \times \dfrac{\pi (22)^2}{360} \approx 127.85 \: \rm in^2\)

Thus, as we have:

Area(PQRS) = 4(Area(DOQ) + Area(QOB))

we get:

Area(PQRS) ≈ 4(105.36 + 127.85) ≈ 932.84 in.²

Thus, the area of the center section when the leaves are down is evaluated being of 932.84 in.²

Answer:

Step-by-step explanation:

a. The range of G is the set of possible values that G can take. G represents the distribution over the number of girls chosen, so G can take any value between 0 and 2, inclusive. That is, the range of G is {0, 1, 2}.

b. To give the distribution over the random variable G, we need to determine the probability of each possible value of G.

Let's consider each possible value of G in turn:

If no girls are chosen (G=0), then both representatives must be boys. The probability of choosing a boy on the first draw is 3/10, and the probability of choosing another boy on the second draw is 2/9 (since there are only 2 boys left). Therefore, the probability of G=0 is (3/10) * (2/9) = 1/15.

If one girl is chosen (G=1), then one representative must be a girl and the other must be a boy. There are two ways this can happen: either the girl is chosen first and then the boy, or the boy is chosen first and then the girl. The probability of choosing a girl on the first draw is 7/10, and the probability of choosing a boy on the second draw is 3/9 (since there are 3 boys left). The probability of choosing a boy on the first draw is 3/10, and the probability of choosing a girl on the second draw is 7/9 (since there are 7 girls left). Therefore, the probability of G=1 is (7/10) * (3/9) + (3/10) * (7/9) = 14/45.

If two girls are chosen (G=2), then both representatives must be girls. The probability of choosing a girl on the first draw is 7/10, and the probability of choosing another girl on the second draw is 6/9 (since there are 6 girls left). Therefore, the probability of G=2 is (7/10) * (6/9) = 7/15.

Therefore, the distribution over the random variable G is:

G=0 with probability 1/15

G=1 with probability 14/45

G=2 with probability 7/15

The properties of exponents

1. \((64)^{1/2}\) = √(64) = 8

2.  \(3m(mn)^(3/2)\) = \(3m(m^{3/2}n^{3/2})\)

3. 2a(5ab)² = \(2a(25a^2b^2) = 50a^3b^2\)

The properties of exponents can be used to simplify and rewrite expressions involving powers and roots. The most common properties are:

Product of powers: \(a^m\) * aⁿ = \(a^{m+n}\)

Quotient of powers: \(a^m\)/ aⁿ = \(a^{m-n}\)

Power of a power: \((a^m)^n\) = \(a^{mn}\)

Power of a product: \((ab)^m\) = \(a^m\) * \(b^m\)

Power of a quotient: \((a/b)^m\) = \(a^m\)/ \(b^m\)

Using these properties, we can rewrite the given equations as follows:

1. \((64)^{1/2}\) = √(64) = 8

The square root of 64 is 8. The power of 1/2 represents the square root.

2. \(3m(mn)^(3/2)\) = \(3m(m^{3/2}n^{3/2})\)

The power of 3/2 represents the square root of the square. We can use the product of powers property to combine the m and n terms under the same square root.

3. 2a(5ab)² = \(2a(25a^2b^2) = 50a^3b^2\)

We can use the power of a product property to square the 5ab term, and then simplify by combining the like terms.

Answer: 1.8 L/h

Step-by-step explanation:

To convert the rate of water dripping from a tap from millilitres per second (ml/sec) to litres per hour (L/h), we need to use conversion factors.

Step 1:

First, let's convert the rate from millilitres per second to litres per second.

There are 1000 millilitres in a litre, so we can divide the rate in millilitres per second by 1000 to get the rate in litres per second:

\(\LARGE \boxed{\textsf{0.5 ml/sec $\div$ 1000 = 0.0005 L/sec}}\)

Step 2:

We can convert the rate from litres per second to litres per hour. There are 3600 seconds in an hour, so we can multiply the rate in litres per second by 3600 to get the rate in litres per hour:

\(\LARGE \boxed{\textsf{0.0005 L/sec $\times$ 3600 = 1.8 L/h}}\)

Therefore, the rate of water dripping from the tap is 1.8 L/h.

By using the quadratic formula, we can conclude that the golf ball will hit the ground at x = 0.5 seconds.

What is the quadratic formula?

The quadratic formula is a formula that gives the solutions of a quadratic equation in the form \(ax^2 + bx + c = 0\), where a, b, and c are constants and x is the variable. The formula is:

x = (-b ± \(\sqrt{b^2 - 4ac}\)) / 2a

This formula can be used to find the values of x that satisfy the quadratic equation.

To find when the golf ball will hit the ground, we need to find the value of x when the height of the golf ball is equal to zero. We can do this by solving the quadratic equation \(-16x^2 + 11x + 6 = 0\) using the quadratic formula:

x = (-b ± \(\sqrt{b^2 - 4ac}\)) / 2a

where a = -16, b = 11, and c = 6. Substituting these values, we get:

x = (-11 ± \(\sqrt{11^2 - 4(-16)(6)}\) ) / 2(-16)

x = (-11 ±  \(\sqrt{361}\))/ (-32)

Simplifying this expression, we get:

x = (-11 ± 19) / (-32)

So the two possible values of x are:

x = 8/16 = 0.5 and x = 30/16 = 1.88

Since the height of the golf ball is equal to zero when it hits the ground, we can conclude that the golf ball will hit the ground at x = 0.5 seconds (rounded to the nearest hundredth).

At the instant when the radius is 9 feet, the height of the cylinder is decreasing at a rate of 2.54 feet per second.

To solve this problem, we can use the formula for the volume of a cylinder, which is V = πr^2h, where V is the volume, r is the radius, and h is the height. Since the volume remains constant at 335 cubic feet, we can set up the equation:
335 = π(9^2)h

Simplifying this, we get:
335 = 81πh
h = 335/(81π)

Now, we can differentiate the volume equation with respect to time to find the rate of change of the height:
dV/dt = 2πrh(dr/dt) + πr^2(dh/dt)

Since the volume is constant, dV/dt = 0. Also, we know that dr/dt = -9 feet per second. At the instant when the radius is 9 feet, r = 9. So we can plug in these values and solve for dh/dt:
0 = 2π(9)h(-9) + π(9^2)(dh/dt)
dh/dt = 2.54 feet per second

Answer:

The value of x is 8

Step-by-step explanation:

In the given triangle

∵ A line segment joining points on two sides and parallel to the 3rd side

→ That means this line segment divided the two sides into equal ratios

∵ It divided the 1st side into 10 and 3x + 1

∵ It divided the 2nd side into 22 and 7x - 1

∴ \(\frac{10}{3x+1}\) = \(\frac{22}{7x-1}\)

→ By using cross multiplication

∵ 10(7x - 1) = 22(3x + 1)

∴ 10(7x) - 10(1) = 22(3x) + 22(1)

∴ 70x - 10 = 66x + 22

→ Subtract 66x from both sides

∵ 70x - 66x - 10 = 66x - 66x + 22

∴ 4x - 10 = 22

→ Add 10 to both sides

∴ 4x - 10 + 10 = 22 + 10

∴ 4x = 32

→ Divide both sides by 4

∴ x = 8

∴ The value of x is 8

For the 32" TV: height = 16", width = 28".

• For the second TV: height = 15", width = 61".

• For the 60" TV: height = 30", width = 52".

The Pythagorean theorem states that in a right triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

Now let's determine the missing measurements for each TV:

1. For the 32" TV, we have the height as 16". To find the width, we need to use the Pythagorean theorem. Let's denote the width as 'w'. The theorem gives us the equation: 16^2 + w^2 = 32^2. Solving this equation, we find that the width is 28".

2. For the second TV with unknown height and a width of 61", we can use the Pythagorean theorem again. Denoting the height as 'h', we have the equation: h^2 + 61^2 = 34^2. Solving for 'h', we find that the height is 15".

3. For the 60" TV with a height of 30" and an unknown width, we can apply the Pythagorean theorem. Denoting the width as 'w', we have the equation: 30^2 + w^2 = 60^2. Solving for 'w', we find that the width is 52".

In summary:

• For the 32" TV: height = 16", width = 28".

• For the second TV: height = 15", width = 61".
