Answer:

60% tiger trout

Step-by-step explanation:

First, do 22+18=  40

Then, when doing % its always out of 100. So, 100 - 40= 60%

Which means, there were 60% Tiger trout.                                                                                                                                                            

(a) 0.5, (b) f_Y(y) = 12y(1-y), (c) 9/128, (d) 7/36 - Probability calculations using joint density function.

(a) To find the Probability that the Turkish tobacco represents over a portion of the mix, we want to incorporate the joint thickness capability over the district where x > 0.5 and y < 1 - x. This gives:

P(X > 0.5) = ∫[0.5,1]∫[0,1-x] 24xy dy dx = 0.5

Consequently, the Probability that the Turkish tobacco represents over around 50% of the mix is 0.5.

(b) To find the negligible thickness capability for the extent of homegrown tobacco, we really want to incorporate the joint thickness capability over all potential upsides of Turkish tobacco:

f_Y(y) = ∫[0,1-y] 24xy dx = 12y(1-y) ; 0 < y < 1

Thusly, the peripheral thickness capability for the extent of homegrown tobacco is f_Y(y) = 12y(1-y).

(c) To find the Probability that the extent of Turkish tobacco is under 1/8 given that the mix contains 3/4 homegrown tobacco, we really want to utilize Bayes' standard:

P(X < 1/8 | Y = 3/4) = P(X < 1/8 ∩ Y = 3/4)/P(Y = 3/4)

We can find the numerator by coordinating the joint thickness capability over the district where x < 1/8 and y = 3/4:

∫[0,1/8] 24xy dx = 27/128

To find the denominator, we coordinate the joint thickness capability over all potential upsides of Turkish tobacco when y = 3/4:

∫[0,1/4] 24xy dx = 3

Thusly, the contingent Probability is:

P(X < 1/8 | Y = 3/4) = (27/128)/3 = 9/128

(d) To find the likelihood that the extent of homegrown tobacco is over two times the extent of the Turkish tobacco, we want to incorporate the joint thickness capability over the area where y > 2x and x + y < 1. This gives:

P(Y > 2X) = ∫[0,1/3]∫[2x,1-x] 24xy dy dx + ∫[1/3,1/2]∫[2x,1-x] 24xy dy dx

= 7/36

Accordingly, the likelihood that the extent of homegrown tobacco is over two times the extent of the Turkish tobacco is 7/36

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Since ΔABC and ΔACD are similar triangles, therefore the length of AC is 18 m.

Similar triangles are triangles with corresponding sides that have the same ratio.

Thus:

AD is parallel to BC (bases of a trapezoid are parallel)

Therefore:

∠ACB = ∠CAD (alternate interior angles)

This implies that, ΔABC ~ ΔACD by AA similarity theorem.

Thus:

AC/DA = CB/AC

Substitute

AC² = 12 × 27

AC = √324

AC = 18 m

Therefore, since ΔABC and ΔACD are similar triangles, therefore the length of AC is 18 m.

Therefore , the solution of the given problem of probability comes out to be a complete probability model cannot be represented by this list.

The main objective of each considerations technique is to calculate the likelihood that a claim is true or that a particular incident will occur. Anything between 0 and 1, were 0 traditionally denotes a percentage and 1 typically denotes the degree of certainty, can be used to represent chance. A probability illustration shows the likelihood that a particular event will occur.

Here,

The probabilities assigned to the outcomes do not add up to 1, hence the following list cannot be a complete probability model.

=> P(2) + P(3) + P(4)

=> 1/12 + 2/3 + 1/4

=>  (1 + 8 + 3) / 12

=> 12 / 12 = 1

In a complete probability model, the total of the probabilities should always be equal to 1, indicating that there is a probability of 1 that one of the events will occur.

In this instance, there is a missing probability since the sum of the probabilities assigned to the possible possibilities is less than 1.

Answer:

\(\text{length of \textit{CA}} \ = \ 12.0 \ \ \ (\text{nearest tenth})\)

Step-by-step explanation:

Radian measure is the ratio of the length of a circular arc to its radius.

A radian is the measurement of the central angle which subtends an arc whose length is equal to the length of the radius of the circle.

In the case of the unit circle, as shown in the figure below, one radian is the angle of the sector with a radius of 1 and circular arclength of 1.

Following this definition, the magnitude, in radians, of one complete revolution of a unit circle is the circumference of the unit circle divided by its radius, \(\displaystyle\frac{2\pi}{1}\) or \(2\pi\). Thus, \(2\pi\) radians is equal to \(360^{\circ}\) degrees. Alternatively, one radian is equal to \(\displaystyle\frac{180^{\circ}}{\pi} \ \approx \ 57.296^{\circ} \ \ \ (3 \ d.p.)\).

Since radian measure is defined as the ratio of the arc length of a sector to its radius, hence

                                                        \(\displaystyle\frac{s}{r} \ = \ \theta \\\\ s \ = \ r\theta\)

where \(s\) is the arclength, \(r\) is the radius, and \(\theta\) is the central angle, in radians.

Therefore, the length of CA is

                                           \(\displaystyle\frac{s}{\theta} \ = \ r \\ \\ r \ = \ \displaystyle\frac{26}{124^{\circ} \ \times \ \displaystyle\frac{\pi}{180^{\circ}} \ \text{rad}} \\ \\ r = \displaystyle\frac{26 \ \times \ 45}{31 \ \times \ 3.14} \\ \\ r\ = \ 12.0 \ \ \ \ \left(\text{nearest tenth}\right)\)

Considering the relation between degree celsius and degree Fahrenheit, The correct answer is D) I and II only.

The relation between degree Celsius (°C) and degree Fahrenheit (°F) is given by the following equation:

°F = (°C * 9/5) + 32

The unit of temperature is a measure of the degree of hotness or coldness of an object or substance. There are several different units of temperature, including the degree Celsius (°C), the degree Fahrenheit (°F), and the kelvin (K).

The equation above shows that temperature F is equal to temperature C multiplied by 9/5 plus 32. This means that a temperature increase of 1 degree Fahrenheit is equivalent to a temperature increase of 9/5 degrees Celsius, or approximately 1.8 degrees Celsius. Therefore, statement I is true.

The equation does not show any relationship between a temperature increase of 1 degree Celsius and a temperature increase of degrees Fahrenheit. Therefore, statement III is not true.

1. The area of the Earth's surface covered in water is approximately 0.71 * 201,061,929 = 142,550,781 square miles.

2. Approximately 1.76% of the Earth's surface lies in the United States.

3. The volume of the entire Earth is approximately 268,082,573,106 cubic miles.

To answer Alonzo's questions, let's calculate the required values using the given information:

1. The area of the Earth's surface that is covered in water:

The Earth's surface area can be calculated using the formula for the surface area of a sphere: 4πr^2. Given that the radius of the Earth is approximately 4,000 miles, we have:

Surface area of the Earth = 4π(4,000)^2 = 4π(16,000,000) ≈ 201,061,929 square miles.

Alonzo can research and find that about 71% of the Earth's surface is covered in water. Thus, the area of the Earth's surface covered in water is approximately 0.71 * 201,061,929 = 142,550,781 square miles.

2. The percent of the Earth's surface that lies in the United States:

The land area of the United States is approximately 3,537,438 square miles. To calculate the percentage, we divide the land area of the United States by the total surface area of the Earth and multiply by 100:

Percentage = (3,537,438 / 201,061,929) * 100 ≈ 1.76%.

Therefore, approximately 1.76% of the Earth's surface lies in the United States.

3. The volume of the entire Earth:

The volume of a sphere can be calculated using the formula: (4/3)πr^3. Substituting the radius of the Earth, we have:

Volume of the Earth = (4/3)π(4,000)^3 = (4/3)π(64,000,000,000) ≈ 268,082,573,106 cubic miles.

Thus, the volume of the entire Earth is approximately 268,082,573,106 cubic miles.

These calculations provide Alonzo with the approximate values he needs regarding the Earth's surface area covered in water, the percentage of the Earth's surface within the United States, and the volume of the entire Earth.

Step-by-step explanation:

10 - (x + 3) = 5

To solve for x, we can start by simplifying the left side of the equation:

10 - (x + 3) = 5

10 - x - 3 = 5

7 - x = 5

Next, we can isolate x on one side of the equation by subtracting 7 from both sides:

7 - x = 5

7 - x - 7 = 5 - 7

-x = -2

Finally, we can solve for x by dividing both sides of the equation by -1:

-x = -2

x = 2

Therefore, the solution to the equation is x = 2.
