Answer:

Name: FE

Length: 13

Step-by-step explanation:

The total length is 34, so you would do 34-21, which equals 13.

Answer:

1.) \(\overline{FE}\)

2.) 13

Step-by-step explanation:

For the first question you just need to see where the missing segment starts and ends. Then you could write it either way EF or FE. I prefer to keep it in order from left to right.

Now for the second question you just have to take the value of the segment that's known and subtract it from the whole segment value to find the missing segment. So in this case we would do 34 - 21 and that will give us 13, so the missing segment is 13.

Answer:

D. 1/2 ≈ 0.083

Step-by-step explanation:

So for the coin there is a 1/2 chance because there are two sides, and only one will be "right." For the side-sided dice, there is a 1/6 chance using the same thinking as the coin.

We can multiply them by each other,

1/2 * 1/6 = 1/12

So the correct answer is D. 1/2 *about* 0.083

3. The Probability of choosing the letters AA is 0, as there are no occurrences of the letter A in both words together.

1. The outcomes in the sample space of choosing a letter from the word THANKS are: T, H, A, N, K, S.

  The outcomes in the sample space of choosing a letter from the word STARK are: S, T, A, R, K.

2. To find the number of outcomes in the sample space, we multiply the number of outcomes for each word.

  Number of outcomes in the sample space = Number of outcomes for the first word × Number of outcomes for the second word

  Number of outcomes in the sample space = 6 (from THANKS) × 5 (from STARK) = 30.

3. The probability of choosing the letters AA would be the number of favorable outcomes (which is 0 in this case) divided by the total number of outcomes in the sample space.

  Probability of choosing AA = Number of favorable outcomes / Total number of outcomes

  Probability of choosing AA = 0 / 30 = 0.

Therefore, the probability of choosing the letters AA is 0, as there are no occurrences of the letter A in both words together.

If the p-value for a hypothesis test is greater than the chosen level of significance, then the null hypothesis cannot be rejected.

In this case, the p-value is 0.11 and the level of significance is 0.05. Since the p-value is greater than the level of significance, we cannot reject the null hypothesis.

Therefore, we do not have sufficient evidence to conclude that the population mean is different from the hypothesized value. In other words, we do not have enough evidence to support the alternative hypothesis.

Thus, rejecting the null hypothesis in favor of the alternative hypothesis is not the correct decision in this case.

Remember that the equation of a parallel line has the same slope but different y-intercept.

Applying the tangent theorem and the Pythagorean theorem, the length of AB is 45 units.

According to the tangent theorem, a tangent will form a right angle with the radius of a circle at the point of tangency.

Tangents are perpendicular to the radius at the tangent point

Triangle ABO is therefore a right triangle.

AO = CO = 24 units

OC is also radius of circle O,

Therefore OC = 24

OB = OC + CB = 24 + 27 = 51

OB = √( OA² + AB²)      

AB = √( OB²  - OA²)  

= √( 2601 - 576 )

= √2025   = 45

Performance relative to the whole class refers to an individual's academic achievement in comparison to the rest of their peers in a particular subject or course.

We describe performance relative to the whole class.

To do this, we'll be using the terms "average", "percentile rank", and "standard deviation".
Average:

Calculate the average performance of the whole class by adding all students' scores and then dividing by the number of students.

This will give you a baseline to compare individual performances against the class average.
Percentile Rank:

Determine the percentile rank of a student by calculating the percentage of students in the class who scored lower than them.

For example, if a student is in the 75th percentile, it means they performed better than 75% of the class.
Standard Deviation:

Calculate the standard deviation, which measures the spread of scores within the class.

A low standard deviation indicates that most students have similar performances, while a high standard deviation shows more variability in scores.
By considering these three factors, you can effectively describe a student's performance relative to the whole class. For example, you might say: "John scored above the class average, placing him in the 80th percentile with a moderate standard deviation, indicating that his performance is better than the majority of his classmates."

Answer:

No, the teacher did not survey a representative sample of the students in the school. The sample of 30 students that he surveyed had a much higher percentage of students already enrolled in art classes (81%) compared to the overall percentage of students in the school who are studying art (11%). This indicates that the sample may have been biased and not representative of the entire student population. In order to obtain a representative sample, the teacher should have taken steps to ensure that the sample of students he surveyed was representative of the overall student population in terms of characteristics such as enrollment in art classes, age, gender, and other relevant factors.

isosceles triangle

Work Shown:

sin(angle) = opposite/hypotenuse

sin(F) = EG/FE

sin(F) = 56/65

Refer to the diagram below.

Answer:

95 degrees

Step-by-step explanation:

The sum of all the angles need to come to 360 degrees. We already have 2 90 degree angles, together 180 degrees. Subtract from 360 to get 180, so we know the other two angles together need to equal 180. x + x + 10 = 180

Add common terms, then subtract 10: 2x = 170

To show that the total charge contained in the charge distribution is Q, we integrate the charge density over the entire volume. The charge density is given by:

ρ(r) = ρ₀(1 - r/R) for r ≤ R,

ρ(r) = 0 for r > R,

where ρ₀ = 3Q/πR³.

To find the total charge, we integrate ρ(r) over the volume:

Q = ∫ρ(r) dV,

where dV represents the volume element.

Since the charge density is spherically symmetric, we can express dV as dV = 4πr² dr, where r is the radial distance.

The integral becomes:

Q = ∫₀ᴿ ρ₀(1 - r/R) * 4πr² dr.

Evaluating this integral gives:

Q = ρ₀ * 4π * [r³/3 - r⁴/(4R)] from 0 to R.

Simplifying further, we get:

Q = ρ₀ * 4π * [(R³/3) - (R⁴/4R)].

Simplifying the expression inside the parentheses:

Q = ρ₀ * 4π * [(4R³/12) - (R³/4)].

Simplifying once more:

Q = ρ₀ * π * (R³ - R³/3),

Q = ρ₀ * π * (2R³/3),

Q = (3Q/πR³) * π * (2R³/3),

Q = 2Q.

Therefore, the total charge contained in the charge distribution is Q.

To show that the electric field in the region r > R is identical to that created by a point charge Q at r = 0, we can use Gauss's law. Since the charge distribution is spherically symmetric, the electric field outside the distribution can be obtained by considering a Gaussian surface of radius r > R.

By Gauss's law, the electric field through a closed surface is given by:

∮E · dA = (1/ε₀) * Qenc,

where ε₀ is the permittivity of free space, Qenc is the enclosed charge, and the integral is taken over the closed surface.

Since the charge distribution is spherically symmetric, the enclosed charge within the Gaussian surface of radius r is Qenc = Q.

For the Gaussian surface outside the distribution, the electric field is radially directed, and its magnitude is constant on the surface. Hence, E · dA = E * 4πr².

Plugging these values into Gauss's law:

E * 4πr² = (1/ε₀) * Q,

Simplifying:

E = Q / (4πε₀r²).

This is the same expression as the electric field created by a point charge Q at the origin (r = 0).

To derive an expression for the electric field in the region r ≤ R, we can again use Gauss's law. This time we consider a Gaussian surface inside the charge distribution, such that the entire charge Q is enclosed.

The enclosed charge within the Gaussian surface of radius r ≤ R is Qenc = Q.

By Gauss's law, we have:

∮E · dA = (1/ε₀) * Qenc.

Since the charge distribution is spherically symmetric, the electric field is radially directed, and its magnitude is constant on the Gaussian surface. Hence, E · dA = E * 4πr².

Plugging these values into Gauss's law:

E * 4πr² = (1/ε₀) * Q.

Simplifying:

E = Q / (4πε₀r²).

This expression represents the electric field inside the charge distribution for r ≤ R.

The probability of at least one 6 showing on any of the three dice is 91/216, which is not equal to 1/2. Therefore, the answer to the question is no, P (A1 U A2 U A3) does not equal 1/2.

The probability of an event A happening, P(A), is the number of ways that A can occur divided by the total number of possible outcomes. In this case, we want to find the probability of at least one 6 showing on any of the three dice, which is represented by P(A1 U A2 U A3).

We can use the formula P(A1 U A2 U A3) = P(A1) + P(A2) + P(A3) - P(A1 ∩ A2) - P(A1 ∩ A3) - P(A2 ∩ A3) + P(A1 ∩ A2 ∩ A3) to find the probability of at least one 6 showings.

Each die has 6 possible outcomes, so the probability of getting a 6 on any one die is 1/6. The probability of getting a 6 on two dice is (1/6)*(1/6) = 1/36, and the probability of getting a 6 on all three dice is (1/6)*(1/6)*(1/6) = 1/216.

Plugging these values into the formula, we get:

P(A1 U A2 U A3) = (1/6) + (1/6) + (1/6) - (1/36) - (1/36) - (1/36) + (1/216) = 91/216

The expected correlation between the supply of a commodity (x) and the price of a commodity (y) depends on the nature of the commodity and market dynamics. However, in general, we would expect a **negative correlation** between the supply of a commodity and its price. Correct option is C.

The law of supply states that as the supply of a commodity increases, assuming demand remains constant, the price tends to decrease. This is because an increase in supply leads to a higher quantity of the commodity available in the market, potentially causing an excess supply or surplus. In such situations, suppliers may lower prices to attract buyers and reduce their inventory.

Conversely, when the supply of a commodity decreases, assuming demand remains constant, the price tends to increase. A decrease in supply results in a lower quantity available in the market, potentially leading to a scarcity or shortage. In such scenarios, suppliers may increase prices to maximize their profits due to the limited availability of the commodity.

It's important to note that real-world markets can be influenced by various factors, including changes in demand, production costs, technological advancements, government policies, and market competition, which can complicate the relationship between supply and price. Nonetheless, the general expectation is that a decrease in supply tends to lead to an increase in price, and an increase in supply tends to lead to a decrease in price, indicating a negative correlation.
