7 4/9 is it greater then or equal to 7 2/3 and pls show me how to simplify it

Answer:

We can solve for y in the equation y = 2y - 2 by substituting y = 2x - 5.

Starting with y = 2y - 2, we substitute y = 2x - 5:

2x - 5 = 2(2x - 5) - 2

Expanding the right side:

2x - 5 = 4x - 12

Next, we isolate y by subtracting 2x from both sides:

-2x - 5 = 4x - 12

Adding 2x to both sides:

-5 = 6x - 12

Adding 12 to both sides:

7 = 6x

Finally, we divide both sides by 6 to solve for x:

x = 7/6

So, y = 2x - 5 = 2(7/6) - 5 = 7/3 - 5 = -14/3.

Therefore, y = -14/3 is the solution to the system of equations y = 2y - 2 and y = 2x - 5.

The n 1/2 of the se 1/4 of the sw 1/4 and the ne 1/4 of the sw 1/4 of Section 19 contains 40 acres.

The method used for land surveying is called the government rectangular survey system.

This system is commonly known as the Public Land Survey System (PLSS) of the United States. It is based on a grid network. The grid is formed with meridians and baselines.

The meridians are the imaginary lines running north to south, and the baselines are the imaginary lines running east to west. The meridians and baselines are named as ranges and townships, respectively.

Each range is 6 miles wide and numbered consecutively, beginning with the one on the far west side of the state. The townships are numbered from 1 to 36, in sequence, beginning at the southeast corner of the state. The government rectangular survey system divides the land into smaller units as follows:

Each township is further divided into 36 sections, each section is one square mile, or 640 acres.

Each section is further divided into halves, or 320 acres, and each half is divided into quarters, or 160 acres, and each quarter is divided into quarters again, or 40 acres.

Finally, each 40-acre parcel is divided into quarters, or 10 acres.

Therefore, the n 1/2 of the se 1/4 of the sw 1/4 and the ne 1/4 of the sw 1/4 of section 19 contains 40 acres.

The top right graph could show the arrow's height above the ground over time.

The initial and the final height are both at eye level, which is the reference height, that is, a height of zero.

This means that the beginning and at the end of the graph, it is touching the x-axis, hence either the top right or bottom left graphs are correct.

The trajectory of the arrow is in the format of a concave down parabola, hitting it's maximum height and then coming back down to eye leve.

Using the slope concept, it is found that the distance from point A to point B is of 521 feet.

The slope is given by the vertical change divided by the horizontal change.

It's also the tangent of the angle of depression.

In this problem, the vertical change is of 118 feet.

At point A, the angle is of 12º, while the horizontal position is of \(x_A\), hence:

\(\tan{12^\circ} = \frac{118}{x_A}\)

\(x_A = \frac{118}{\tan{12^\circ}}\)

\(x_A = 555.1\)

At point B, the angle is of 74, while the horizontal position is of \(x_B\), hence:

\(\tan{74^\circ} = \frac{118}{x_B}\)

\(x_B = \frac{118}{\tan{74^\circ}}\)

\(x_B = 33.84\)

The distance in feet is of:

\(d = x_A - x_B = 555.1 - 33.84 \approx 521\)

The we can conclude that there is not enough evidence to suggest that the selection process discriminates against Mexican-Americans.

Answer:The probabilities of the given problem are as follows:Probability of 0 Mexican Americans among 12 jurors = 0.0002Probability of 1 Mexican American among 12 jurors = 0.0014Probability of 2 Mexican Americans among 12 jurors = 0.0073Probability of 3 Mexican Americans among 12 jurors = 0.0285Probability of 4 Mexican Americans among 12 jurors = 0.0818Probability of 5 Mexican Americans among 12 jurors = 0.1712Probability of 6 Mexican Americans among 12 jurors = 0.2547Probability of 7 Mexican Americans among 12 jurors = 0.2558Probability of 8 Mexican Americans among 12 jurors = 0.1557Probability of 9 Mexican Americans among 12 jurors = 0.0434Probability of 10 Mexican Americans among 12 jurors = 0.0093Probability of 11 Mexican Americans among 12 jurors = 0.0011Probability of 12 Mexican Americans among 12 jurors = 0.0001The probability of exactly 6 Mexican-Americans among 12 jurors can be calculated by using the probability mass function(PMF).It is P(X = 6) = 0.2547We have to round our answer to four decimal places. Therefore, the required probability of 6 Mexican-Americans among 12 jurors is 0.2547.

The probability of 6 or fewer Mexican-Americans among 12 jurors can be calculated as follows:P(X ≤ 6) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5) + P(X = 6)P(X ≤ 6) = 0.0002 + 0.0014 + 0.0073 + 0.0285 + 0.0818 + 0.1712 + 0.2547P(X ≤ 6) = 0.0374We have to round our answer to four decimal places. Therefore, the required probability of 6 or fewer Mexican-Americans among 12 jurors is 0.0374.Solution:It is given that 12 jurors are randomly selected from a population in which 77% of the people are Mexican-Americans.We can use probability distribution table to find the required probabilities. The given probability distribution table is:To find whether the selection process discriminates against Mexican-Americans or not, we have to compare the expected frequency with the observed frequency. We can use the chi-square test for goodness of fit to compare the observed frequency with the expected frequency.The null hypothesis for the chi-square test of goodness of fit is that the observed frequency and the expected frequency are equal. The alternate hypothesis is that the observed frequency and the expected frequency are not equal.The expected frequency can be calculated as follows:Expected Frequency = Total Frequency × Probability of Mexican-AmericanSo, the expected frequency of Mexican-American jurors can be calculated as:Expected frequency of Mexican-Americans = 12 × 0.77 = 9.24

The expected frequency of non-Mexican-Americans can be calculated as:Expected frequency of Non-Mexican-Americans = 12 − 9.24 = 2.76Now, we can calculate the chi-square statistic as follows:Chi-Square = ∑((O − E)² / E)where, O = Observed frequencyE = Expected frequencyChi-Square = ((0 − 0.0002)² / 0.0002) + ((1 − 0.0014)² / 0.0014) + ((2 − 0.0073)² / 0.0073) + ((3 − 0.0285)² / 0.0285) + ((4 − 0.0818)² / 0.0818) + ((5 − 0.1712)² / 0.1712) + ((6 − 0.2547)² / 0.2547) + ((6 − 0.2558)² / 0.2558) + ((2.76 − 2.76)² / 2.76)Chi-Square = 5.23The degree of freedom can be calculated as follows:Degree of Freedom = Number of Categories − 1Degree of Freedom = 12 − 1 = 11At 95% confidence level and 11 degrees of freedom, the critical value of the chi-square statistic is 19.68.As the calculated chi-square statistic (5.23) is less than the critical value of the chi-square statistic (19.68), we fail to reject the null hypothesis. Therefore, we can conclude that there is not enough evidence to suggest that the selection process discriminates against Mexican-Americans.

To find when half of the population of bacteria will be left given a decay rate of -17% per hour, you can use the formula for exponential decay:

Final Population = Initial Population * (1 + Decay Rate)^Time

In this case, you want to find the time when half of the population is left, so:

0.5 * Initial Population = Initial Population * (1 - 0.17)^Time

Now, you can solve for Time:

0.5 = (1 - 0.17)^Time
0.5 = 0.83^Time

To solve for Time, you can take the logarithm of both sides of the equation:

log(0.5) = log(0.83^Time)

Using the logarithm property, you can move Time to the front of the equation:

log(0.5) = Time * log(0.83)

Finally, solve for Time by dividing both sides by log(0.83):

Time = log(0.5) / log(0.83)

After calculating, you'll find that Time ≈ 3.94 hours. So, it will take approximately 3.94 hours for half of the bacterial population to be left, given a decay rate of -17% per hour.

Upper Control Limit for R Chart: UCL = D4 * R-Bar , UCL = 2.114 * 1.000, UCL ≈ 2.115 cm. Therefore, the correct answer is 2.115 cm(d).

To calculate the upper control limit for the R Chart, we need to use the following formula:

Upper Control Limit (UCL) = D4 * R-Bar

Where:

- D4 is a constant value based on the sample size (n=5 in this case).

- R-Bar is the average range of the samples, which is given as 1.000 cm.

The value of D4 for a sample size of 5 is 2.114. (You can find this value in statistical reference tables.)

Now, we can calculate the UCL:

UCL = D4 * R-Bar

   = 2.114 * 1.000

   = 2.114 cm

Rounding to 3 decimal places, the upper control limit for the R Chart is 2.114 cm.

To determine the proportion that proves the relationship involving the tangent of angle D in the dilated triangles, we need more information about the angles and sides involved in triangles BAC and BDE. Specifically, we need the measures of the angles and the lengths of the sides to establish a proportion.

Without the specific measurements or relationships between angles and sides, we cannot provide a proportion that directly involves the tangent of angle D in this scenario. Dilations with a scale factor of 2 generally result in corresponding sides being twice as long, but the angles may or may not maintain the same measures. To establish a proportion involving the tangent of angle D, we would need more specific information about the triangle's properties, such as angle measures, side lengths, or additional relationships between angles and sides.

Step-by-step explanation:

The probability distribution used would be the negative binomial distribution with parameters p (either P(B) or P(G)) and r = 3. The PMF of X would then be calculated using the negative binomial distribution formula, taking into account the number of trials (number of children) until three children of the same gender are achieved.

The probability distribution that would be used to determine the probability mass function (PMF) of X, where X represents the number of children until the family has three children of the same gender, is the negative binomial distribution.

The negative binomial distribution models the number of trials required until a specified number of successes (in this case, three children of the same gender) are achieved. It is defined by two parameters: the probability of success (p) and the number of successes (r).

In this scenario, let's assume that the probability of having a boy is denoted as P(B) and the probability of having a girl is denoted as P(G). Since the family is aiming for three children of the same gender, the probability of success (p) in each trial can be represented as either P(B) or P(G), depending on which gender the family is targeting.

Therefore, the probability distribution used would be the negative binomial distribution with parameters p (either P(B) or P(G)) and r = 3. The PMF of X would then be calculated using the negative binomial distribution formula, taking into account the number of trials (number of children) until three children of the same gender are achieved.
