Jina is taller than 90% of US women if her height is at least 67.3 inches. Jina's height is approximately 67.3 inches.

Jina's height can be found using the z-score formula: z = (x - μ) / σ, where x is Jina's height, μ is the mean height of US women, and σ is the standard deviation of the heights. We need to find the z-score such that the area under the normal curve to the right of it is 0.10 (since Jina is taller than 90% of the population).

Using a z-score table or a calculator, we find that the z-score corresponding to an area of 0.10 is approximately 1.28. Substituting into the z-score formula and solving for x, we get:

1.28 = (x - 64.5) / 2.2

x - 64.5 = 2.816

x = 67.316

Rounding to one decimal place, Jina's height is approximately 67.3 inches.

In other words, Jina is taller than 90% of US women if her height is at least 67.3 inches.

The current drawn by R2 is 3.333A or 3333mA in parallel combination in ohms.

In a parallel combination, the voltage across both resistors is the same. However, the current is divided between the two resistors based on their individual resistances. Using Ohms law (V = IR), we can find the voltage across the resistors:

According to the specific resistances of the resistors in a parallel circuit, the current is distributed among them. More current will flow through the resistor with the lower resistance than the one with the greater resistance. This is due to the fact that the lower resistance provides less resistance to the current flow. In this instance, R1 will draw more current than R2 since it has a lower resistance than R2.

V = IR1 = (10A)(5Ω) = 50V

V = IR2 = (I)(15Ω)

We can find current I by solving this particular equation:

I = V/R2 = (50V)/(15Ω) = 3.33A

Convert this ampere value to milliamps, in which we have to multiply by 1000:

I = 3.33A * 1000 = 3333mA or 3.333A

Current drawn by R2 is 3.333A or 3333mA.

There are a variety of factors that can lead to violent protests, but two significant factors are perceived injustice and lack of political representation.

Perceived injustice: When people feel that they have been wronged, marginalized, or oppressed by a system or institution, they may resort to violent protest as a way to express their anger and frustration. This is particularly true when people believe that peaceful means of protest have been ignored or have failed to bring about change. For example, if a community feels that they are being unfairly treated by the police, and previous attempts to seek redress through peaceful protests or other channels have failed, they may turn to violent protest as a last resort.

Lack of political representation: When people feel that their voices are not being heard, they may resort to violent protests as a way to force attention to their concerns. This can happen when marginalized groups feel excluded from the political process, or when they feel that their interests are being ignored by those in power. If people feel that their concerns are not being taken seriously, they may turn to violent protest as a way to make their voices heard.

The response will be P(neither blue nor white) = 0, in accordance with the information provided.

A fraction is a component of a whole. Mathematically, the number is expressed as a quotient, in which the both the numerator and the denominator are divided. In a simple fraction, both are integers. The numerator or decrease of a complicated fraction contains a fraction. The numerator of an appropriate fraction is less than the denominator.

The total probability of all potential outcomes must equal 1. As P(blue) and P(white) are both 1, there cannot be any other card colors. P(neither blue nor white) is therefore equal to zero.

If there are additional cards of different colors and the information provided is insufficient or inaccurate, we can also apply the following formula:

P(neither blue nor white) = 1 - P(blue) - P(white)

Assuming that there are just three possible card colors (blue, white, and another color), the following equation can be constructed using the provided data:

P(blue) + P(white) + P(another color) = 1

P(white) and P(blue) are both 1, so we have:

1 + 1 + P(another color) = 1

When we simplify this equation, we obtain:

P(another color) = -1

The presented information does not support the notion that there are merely three possible card colors, hence this is not a legitimate probability. Hence, the only viable response is.

P(neither blue nor white) = 0

The answer is 0/1, which can be simplified to 0.

what is probability?

Probability is a measure of the likelihood or chance of an event occurring.

If P(blue) and P(white) are both 1, it means that all the cards are either blue or white.

Let's assume there are a total of n cards. Then,

P(blue) + P(white) = 1

=> Number of blue cards + Number of white cards = n

Given that P(blue) = P(white) = 1, we can conclude that there are n/2 blue cards and n/2 white cards.

Therefore, the probability of choosing a card that is neither blue nor white is the probability of choosing a card of a different color. There are no other colors given, so we can assume that there are no cards of any other color.

Hence, the probability of choosing a card that is neither blue nor white is 0.

So, P(neither blue nor white) = 0.

Therefore, the answer is 0/1, which can be simplified to 0.

The correct answer is A. Definition of midsegment. In this step, the proof is demonstrating that the midsegment of a triangle is parallel to the median of the triangle.

A triangle is a three-sided polygon. It is one of the basic shapes in geometry. It has three sides and three angles, with the sum of the angles of a triangle being always 180 degrees. Triangles come in various shapes and sizes, and are classified by their angles or sides. Examples of triangle shapes include equilateral, isosceles and scalene.

The midsegment is defined as the line segment that connects the midpoints of two sides of the triangle. The median is defined as the line segment that connects a vertex of the triangle with the midpoint of the opposite side. Therefore, in order to prove that the midsegment is parallel to the median, the definition of the midsegment must be used. The definition of the midsegment states that it is the line segment that connects the midpoints of two sides of the triangle, which is necessary in order to prove that it is parallel to the median.

If u is indirectly proportional to t³ - 3, the value of u when t = 3 is 5.

Proportional relationships are relationships between two variables where their ratios are equivalent.

Given that;

u is indirectly proportional to t³ - 3;

u ∝ 1/( t³ - 3)

u = k/( t³ - 3)

Where k is the proportionality constant.

First, we determine the proportionality constant.

To find k, we can use the initial condition that;

24 = k / (2³- 3)

24 = k / (8 - 3)

24 = k / 5

k = 24 × 5

k = 120

Hence, the equation relating u and t is:

u = k/( t³ - 3)

Plug in k = 120

u = 120/( t³ - 3)

To find u when t = 3, we can substitute t = 3 into the equation:

u = 120/( t³ - 3)

u = 120/( 3³ - 3)

u = 120/( 27 - 3)

u = 120/24

u = 5

Therefore, the value of u is 5.

The correct options are A) Pull two times as many green cubes as blue cubes , B) Pull a blue cube 28 times, and E) Pull a red cube 16 times.

To determine which of the following amounts you would expect to pull, we need to calculate the probabilities of drawing each color cube and then apply that probability to 100 draws.

1. Calculate the total number of cubes in the bag:

Total cubes = 7 blue + 4 red + 14 green = 25 cubes

2. Calculate the probability of drawing each color:

P(blue) = 7/25

P(red) = 4/25

P(green) = 14/25

3. Apply the probabilities to 100 draws:

Blue: 100 × (7/25) = 28

Red: 100 × (4/25) = 16

Green: 100 × (14/25) = 56

Now we can evaluate the given statements:

A) Pull two times as many green cubes as blue cubes

56 green cubes is exactly 2 times 28 blue cubes, so A is correct.

B) Pull a blue cube 28 times

Step-by-step explanation:

in a trapezoid

• each lower base angle is supplementary to the upper base angle on the same side.

∠ ART = 40° + 25° = 65°

then

∠ PAR = 180° - ∠ ART = 180° - 65° = 115° , so

∠ PAR = x = 115

the sum of the 3 angles in Δ PAR = 180° , that is

Step-by-step explanation:

The probability of selecting a boy from the class on the first draw is 7 boys out of 17 students total, or 7/17.

After the first boy is selected, there will be 6 boys and 10 girls left in the class.

So the probability of selecting a boy on the second draw, given that a boy was already selected on the first draw, will be 6 boys out of 16 remaining students, or 6/16.

To find the probability that both students selected are boys, we can multiply the probabilities of selecting a boy on the first and second draws:

P(boy and then boy) = P(boy on first draw) x P(boy on second draw | boy on first draw)

P(boy and then boy) = (7/17) x (6/16)

P(boy and then boy) = 21/136

The correct answer is (A): "its sampling distribution is centered exactly at the parameter it estimates."

An estimator is a statistic that is used to estimate an unknown parameter in a population. A point estimator is a single value that is used to estimate the population parameter. The goal of a point estimator is to provide an estimate that is as close to the true value of the parameter as possible.

One way to evaluate the quality of a point estimator is to look at its bias, which is the difference between the expected value of the estimator and the true value of the parameter it is estimating. An estimator is unbiased if its expected value is equal to the true value of the parameter it estimates. In other words, an unbiased estimator is centered exactly at the parameter it estimates.

In the context of the given problem, the sample mean of weekly computer usage time (8.5 hours) is a point estimator for the population mean weekly computer usage time. To evaluate whether this estimator is unbiased, we would need to look at its sampling distribution and check whether its expected value (i.e., the mean of the sampling distribution) is equal to the true population mean.

The student's test score is 0.76 standard deviations above the mean of the class.

A z-score is a measure of how many standard deviations a data point is from the mean of the data set. It is calculated by subtracting the mean from the data point and dividing by the standard deviation. In this case, the teacher wants to convert the test scores into z-scores relative to the mean and standard deviation of the students in the class.

The formula for calculating a z-score is:

z-score = (data point - mean) / standard deviation

Using the mean and standard deviation provided in the question, the teacher can calculate the z-score for each student's test score by plugging in the values into the formula. For example, if a student scored 150 on the test, their z-score would be:

z-score = (150 - 130) / 26.2
z-score = 0.76

This means that the student's test score is 0.76 standard deviations above the mean of the class. The teacher can use this information to understand how each student's test score compares to the rest of the class.
