Please answer correctly !!!!!!!!!!!!!!!! Will mark brainliest !!!!!!!!!!!!!!!!!

Answer:

a. We need to determine if the two paths intersect or not. Biker A travels due east while Biker B travels southeast at a 61° angle. Since 61° is less than 90°, Biker B's path will intersect with Biker A's path.

b. Since the paths intersect, the bikers do not need to travel any farther to meet each other.

c. The angle between the two paths can be found by subtracting the angles formed by each path with the horizontal. The angle formed by Biker B's path with the horizontal is 61°, and the angle formed by Biker A's path with the horizontal is 180° - 89° = 91°. Therefore, the angle between the two paths is 91° - 61° = 30°.

d. The measure of the angles formed by the paths the bikers took add up to 180°. Since one angle is 61° and the other is 91°, the third angle must be 180° - 61° - 91° = 28°. The paths are not parallel since the angle between them is not 0° or 180°.

e. Since the paths intersect and the angles are all different, the triangle formed by the paths is scalene.

f. To determine how far the bikers traveled together, we need to find the length of the segment that joins the points where the paths intersect. To do this, we can use trigonometry. Let x be the distance from the intersection point to the end of Biker A's path. Then, we can use the fact that the tangent of 30° is equal to the opposite side over the adjacent side in the right triangle formed by Biker A's path, the segment joining the two paths, and a vertical line passing through the intersection point. We get:

tan(30°) = x / 12

x = 12 * tan(30°)

x ≈ 6.93

Therefore, the two bikers traveled together for a distance of 6.93 miles.

Answer:

x = 10

Step-by-step explanation:

Every triangle has 180o. Just add the three angles together.

8x + 5 + 3x + 25 + 4x = 180         Combine the like terms.

15x + 30 = 180                              Subtract 30 from both sides

15x = 180 - 30                              Combine

15x = 150                                      Divide by 15

x = 150/15

x = 10

Answer:

10

Step-by-step explanation:

8x + 5° + 3x + 25° + 4x = 180° (angle sum property of a triangle)

8x + 3x + 4x + 5° + 25° = 180°

15x + 30° = 180°

15x = 180° - 30°

15x = 150°

x = 150/15

x = 10°

Professional tennis players may constitute a(n) symbolic group for an amateur tennis player

A symbolic group is one in which a person is unlikely to be accepted even if they act like a member by emulating their beliefs, attitudes, and behaviors. For young people, cricket players like Sachin Tendulkar, Sourav Ganguly, etc., may serve as a representative group. By concentrating on the small scale, symbolic interactionism examines the individual within a community and their relationships with others.

Similar to this, professional tennis players may serve as a symbolic group for an amateur tennis player who identifies with certain players by mimicking their behavior whenever possible, even though the amateur tennis player does not meet the criteria for membership in the category of professional tennis players because he or she does not have the necessary skills or access to the professional circuit.

Answer:the question is cut off

Step-by-step explanation:

To find the average rate of speed of the wind and the plane, we can use the formula: distance = rate × time.  Therefore, the average rate of speed of the wind is P/3.5, and the average rate of speed of the plane is P.

we have the equation: distance = (P + W) × 1/3. On the return trip against the headwind, the effective speed of the plane is the difference between the plane's rate and the wind's rate: P - W. Given that the time taken is 3/5 hour, we have the equation: distance = (P - W) × 3/5. Since the distance traveled is the same in both cases, we can set up the following equation: (P + W) × 1/3 = (P - W) × 3/5.

On the left side, we have (P + W) × 1/3 = (P/3) + (W/3).
On the right side, we have (P - W) × 3/5 = (3P/5) - (3W/5).
Simplifying further, we have 5W + 9W = 9P - 5P.
Combining like terms, we get 14W = 4P.
Finally, we can divide both sides by 4 to solve for W: W = P/3.5.

Using f -statistic value relationship with population variation , the ratio of population variance lie in interval [0.1008,2.021].

0.1008 <σ₁²/σ₂²< 2.021

So, the correct option is option( d).

A professor wants to compare the variances of scores between two sections of classess.

we have

sample size for first class score (n₁) = 13

sample size for second class score (n₂) = 16

confidence interval is 99%

sample variance of first sample (s₁²) = 203.25

sample variance of second sample (s₂²)= 474.42

Using the relationship

( s₁² /s₂² )/F₁₋ₐ/₂ < σ₁²/σ₂²< ( s₁²/s₂²)/Fₐ/₂

a = 0.005

F at (1- a/2) or F₀.₉₉₅, ₁₃,₁₆= 4.249

F at a/2 or F₀.₀₀₅,₁₃, ₁₆ = 0.2118

plugging all known values in above formula

=> ( 203.25/474.42)/4.249<σ₁²/σ₂²< (203.25/474.42)/0.2118

=> 0.1008 <σ₁²/σ₂²< 2.021

=> σ₁²/σ₂² ∈[0.1008,2.021]

The correct answer is b. Each block should consist of volunteers who live in similar environments when it comes to mosquitoes.

Explanation:

In a randomized block design, blocks are formed to control for potential confounding factors or sources of variation that may affect the outcome of the experiment. By forming blocks based on similar environments when it comes to mosquitoes, the researchers ensure that any differences in the effectiveness of the bracelet and bug spray are not solely due to variations in mosquito exposure.

If the researchers were to choose option a (both the volunteers and researchers should be kept blind as to which block the volunteers are in), it would be related to blinding the participants and researchers to the treatment assignment, not forming blocks. This method does not address the need for controlling potential confounding factors.

Option c (each block should consist of volunteers who live in different environments when it comes to mosquitoes) would not be suitable because it would introduce additional variability and make it difficult to compare the effectiveness of the bracelet and bug spray.

Option d (each volunteer should be randomly assigned to a block) is not recommended in this case because it does not take into account potential confounding factors related to mosquito exposure.

Option e (volunteers in one block should use the bracelet, while volunteers in the other block should use bug spray) does not control for potential confounding factors, as individuals in different blocks may have different levels of mosquito exposure.

The equation Chad should program is \(y = -0.04x^2 + 20x.\)

The equation that Chad should program into his rocket launcher to win is:

\(y = -0.04x^2 + 8x\)

This is a quadratic equation in standard form, where the coefficient of x^2 is negative, indicating that the path of the rocket is a downward facing parabola. The coefficient of x^2 is -0.04, which means that the parabola is relatively flat, ensuring that the rocket will travel a horizontal distance of 20 feet when it reaches a height of 100 feet.

To sketch the rocket’s path, we can plot points on the graph of the equation. For example, when x = 0, y = 0, so the rocket starts at the origin. When x = 50, y = 200, so the rocket reaches its maximum height at x = 50 and y = 100. When x = 100, y = 0, so the rocket lands 20 feet away from the launch pad at ground level. We can connect these points to sketch the path of the rocket.

The probability that more than the expected number of Sikh youths wear a turban in a random sample of five is 0.3671 (rounded to 4 decimal places).

a. Using the binomial distribution formula, we can determine the likelihood that two out of a random sample of five Sikh teenagers are turban-wearing:

\(P(X = 2) = (5 pick 2) (5 choose 2) * (0.75)^3 * (0.25)^2\)

"X" indicates the proportion of Sikh adolescents who wear turbans, "5 choose 2" indicates the number of possible methods to select 2 Sikhs from a group of 5, and "0.75" and "0.25" indicate the likelihoods that a Sikh youngster will not be wearing a turban and will be wearing one, respectively.

This expression can be made simpler by using a calculator to become:

P(X = 2) = 10 * 0.421875 * 0.0625 = 0.2659

Hence, 0.2659 percent chance exists that two out of every five Sikh youngsters in a random sample will be turban-wearing (rounded to 4 decimal places).

Using the complement rule, we can determine the likelihood that two or more of a random sample of five Sikh teenagers are wearing turbans:

P(X >= 2) = 1 - P(X 2)

where X is the proportion of young Sikhs who are turban-wearing.

P(X 2) is the likelihood that fewer than 2 of five Sikh teenagers chosen at random will be turban-wearing.

This can be calculated as:

P(X 2) equals P(X = 0) plus P(X = 1).

P(X = 0) = (5 select 0) * (0.75) * (5 select 0) * (0.25) * 0 = 0.2373

P(X = 1) = (5 select 1) * (0.75) * (4 select 1) * (0.25) * 1 = 0.3956

P(X 2) = 0.2373 + 0.3956 = 0.6329 as a result.

We can then compute P(X >= 2) = 1 - 0.6329 = 0.3671 using the complement rule.

Consequently, there is a 0.3671 percent chance that two or more of five Sikh teenagers chosen at random will be turban-wearing (rounded to 4 decimal places).

c. The following formula can be used to determine how many Sikh teenagers in a random sample of five are likely to wear a turban:

E(X) = n * p = 5 * 0.25 = 1.25

Using the cumulative binomial distribution function, we can determine the likelihood that more Sikh teenagers than predicted in a random sample of five wear turbans:

P(X > 1) = 1 - P(X <= 1)

P(X = 1) equals P(X = 0) plus P(X = 1).

P(X = 0) = (5 select 0) * (0.75) * (5 select 0) * (0.25) * 0 = 0.2373

P(X = 1) = (5 select 1) * (0.75) * (4 select 1) * (0.25) * 1 = 0.3956

Therefore,

P(X <= 1) = 0.2373 + 0.3956 = 0.6329

The complement rule can then be used to determine:

P(X > 1)

P(X > 1) = 1 - 0.6329 = 0.3671

Hence, in a random sample of five Sikh adolescents, the likelihood that there are more turban-wearing Sikh youths than expected is 0.3671. (rounded to 4 decimal places).

the margin of error M. E. That corresponds to a sample of size 279 with 24% successes at a confidence level of 99% is approximately 0.0608, or 6.08%

To find the margin of error (M.E.) for a sample proportion, we can use the following formula:

M.E. = z × √(p × (1-p))/n

where:

z is the z-score corresponding to the desired confidence level

p is the sample proportion

n is the sample size

In this case, we are given:

n = 279 (sample size)

p = 0.24 (sample proportion)

Confidence level = 99%

To find the z-score for a 99% confidence level, we can use a standard normal distribution table or calculator. The z-score for a 99% confidence level is approximately 2.576.

Substituting these values into the formula, we get:

M.E. = 2.576 × √(0.24 × (1-0.24))/279

M.E. ≈ 0.0608

Therefore, the margin of error is approximately 0.0608, or 6.08%. This means that we can be 99% confident that the true population proportion is within 6.08% of the sample proportion (i.e., between 0.24 - 0.0608 = 0.1792 and 0.24 + 0.0608 = 0.3008).

We already know that both triangles have a congruent side length.

We also know angle KVM or UVW are the same

We only have to know if VM and WV are the same.

This way, each triangle will have two congruent side lengths and a angle. The third side will therefore be the same.

By the same logic, if we know that KM and UW are the same, the two triangles are also congruent.

To determine if two triangles are congruent using the SAS (Side-Angle-Side) criterion, we need additional information about the length of one side, the measure of one angle, and the length of another side in both triangles.

This information is crucial in order to establish the congruence between the triangles. For example, let's consider two triangles, triangle ABC and triangle DEF. To prove that these triangles are congruent using the SAS criterion, we need to know: 1. The length of side AB in triangle ABC and the length of side DE in triangle DEF. 2. The measure of angle A in triangle ABC and the measure of angle D in triangle DEF. 3. The length of side BC in triangle ABC and the length of side EF in triangle DEF. By knowing these measurements, we can compare the corresponding sides and angles of the two triangles. If the lengths of the corresponding sides are equal and the measures of the corresponding angles are equal, then we can conclude that the two triangles are congruent by the SAS criterion.
