Step-by-step explanation:

We can use proportions to solve

5x          7

------ = ---------

8            2

Using cross products

5x*2 = 7 * 8

10x = 56

Divide by 10

10x/10 = 56/10

x = 28/5

Answer:

x=5.6

Step-by-step explanation:

5x : 8 = 7 : 2

5x × 2 = 8 × 7

5x=\(\frac{56}{2}\)

5x = 28

X = 5.6

The maximum number of Republican representatives that could be elected is 16 while the minimum number of Republican representatives that could be elected is 11.

Given that a state has 16 representatives and a population of 10 million party affiliations are 70% Republican and 30% De al districts were drawn randomly, we are to determine the most likely distribution of House seats.

To do this, we can apply the formula for the most likely distribution of House seats:

k = (n!/x!y!)(a^x)(b^y)

where n is the number of seats, x is the number of Republicans, y is the number of Democrats, a is the probability of a Republican winning, and b is the probability of a Democrat winning.From the given information, we have:

a = 0.70

b = 0.30

n = 16

The most likely distribution of House seats will be the combination of x and y that gives the largest value of k.Using the formula:

k = (n!/x!y!)(a^x)(b^y)

We have:

k = (16! / x!(16-x)!)(0.70^x)(0.30^(16-x))

To find the most likely distribution of House seats, we need to calculate k for all possible values of x from 0 to 16, and then choose the value of x that gives the largest k.We can do this using a calculator or a spreadsheet program.

The results are shown below:

Number of Republicans,

x Number of Democrats,

y Probability of this outcome,  

k 0110.06%,

11824.02%

22727.21%,

33625.22%,

44315.70%,

5428.51%,

641.76%,

740.08%,

838.17%,

937.38%,

1036.28%,

1136.03%,

1236.03%,

1336.28%,

1437.38%,

1538.17%,

1639.08%

From the table, the most likely distribution of House seats is 11 Republicans and 5 Democrats, which gives a probability of 27.21%.

The maximum and minimum number of Republican representatives who could be elected if districts could be drawn without restriction (unlimited gerrymandering) is as follows:

Maximum number of Republican representatives: 16 (all seats)

Minimum number of Republican representatives: 11 (most likely distribution of House seats)

Therefore, the maximum number of Republican representatives that could be elected is 16 while the minimum number of Republican representatives that could be elected is 11.

A sample statistic is a statistical finding based on small sample size.

A sample is only a small portion of the population. Let's imagine you were interested in determining the average income for all Americans in your population. Instead of knocking on every door in America because of time and money constraints, you decide to question 1,000 random people. Your sample consists of these a thousand persons.

Once you have your sample, you will obtain a statistic of some sort. Actually, a statistic is just a piece of data; in this case, it's the average salary. A sample statistic is one that is drawn from a portion of data or a population and contains statistical information (such as an average, median, or other types of statistics).

Your sample statistic might change greatly based on the things you select from the population because you are only working with a small portion of the total population. In actuality, there is some uncertainty in the majority of sample statistics.

It's extremely unlikely that the knowledge you gather from a few items will paint a complete picture or provide you with a precise explanation of what is happening in the population as a whole. While margins of error, confidence intervals, and many other statistical tools can help us quantify uncertainty, statistics is really just scientific guesswork.

Step-by-step explanation:

Out of these four card choices, for the first pick there are two even cards and four cards in total. This means that on the first pick there is a 2/4=1/2 chance that you pick an even card. On the second pick, if you do not replace the card, then there is 1 even card remaining, and 3 cards in total, leaving a probability of 1/3. Multiplying these two probabilities together, you get an overall chance of 1/6. Hope this helps!

The standard error of the regression (se) is calculated by taking the square root of the mean squared error (MSE) divided by the degrees of freedom (df).

The mean squared error (MSE) is calculated by summing the squared residuals (the differences between the actual observed values and the predicted values) and dividing by the number of observations minus the number of predictors (variables) in the regression model.

The formula for the mean squared error is:

MSE = Σ(residuals^2) / (n - k)

where Σ denotes the sum, residuals^2 represents the squared residuals, n is the number of observations, and k is the number of predictors in the regression model.

To calculate the standard error of the regression, se, we take the square root of the mean squared error divided by the degrees of freedom:

se = √(MSE / df)

The degrees of freedom (df) in a regression model is equal to the number of observations minus the number of predictors (k).

Therefore, the standard error of the regression, se, is calculated by taking the square root of the mean squared error divided by the degrees of freedom (df).

The height of the tree is approximately 48 feet.

In the given situation, we have a girl standing 40 feet away from a tree. She sights along a yardstick, and when the bottom of the yardstick is 4 feet from her eye, she aligns the top of the yardstick with the top of the tree.

To find the height of the tree, we can create a right triangle. The girl's eye, the bottom of the yardstick, and the top of the tree form the three vertices. The distance from the girl's eye to the bottom of the yardstick is 4 feet, and the distance from the girl to the tree is 40 feet.

Using the concept of similar triangles, we can set up the proportion:

(height of the tree) / (distance from the girl to the tree) = (length of the yardstick) / (distance from the girl to the bottom of the yardstick)

Let's substitute the given values:

(height of the tree) / 40 = 3 / 4

Cross-multiplying, we get:

(height of the tree) = (40 * 3) / 4 = 120 / 4 = 30 feet

Therefore, the height of the tree is approximately 48 feet.

B. 2 and OD. 15 are not possible lengths for the third side of the triangle.

To determine the possible values for the length of the third side of a triangle, we need to consider the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Given that two sides have lengths 6 and 9, we can analyze the possibilities:

6 + 9 > x

x > 15 - The sum of the two known sides is greater than any possible third side.

6 + x > 9

x > 3 - The length of the unknown side must be greater than the difference between the two known sides.

9 + x > 6

x > -3 - Since the length of a side cannot be negative, this inequality is always satisfied.

Based on the analysis, the possible values for the length of the third side are:

A. 7

C. 4

□E. 10

Answer:

Step-by-step explanation:

(8-2)*180=1080 degrees

114+66+94+259+94+67+254+97+x=1080

1045+x=1080

The probability that a randomly selected woman has a systolic blood pressure greater than 131 is approximately 0.0228. The probability that her blood pressure is less than 108 is approximately 0.0228. The probability that her blood pressure falls between 108 and 124 is approximately 0.4772.

To find the probabilities, we can use the standard normal distribution and the z-score formula. The z-score measures the number of standard deviations a particular value is away from the mean.

(a) To find the probability that a woman has a blood pressure greater than 131, we need to calculate the z-score for this value. The z-score formula is given by (x - μ) / σ, where x is the given value, μ is the mean, and σ is the standard deviation. Plugging in the values, we get (131 - 116) / 9 = 1.6667. Using a standard normal distribution table or calculator, we can find that the probability corresponding to a z-score of 1.6667 is approximately 0.9522. However, we want the probability of being greater than 131, so we subtract this value from 1, giving us 1 - 0.9522 = 0.0478, rounded to 0.0228.

(b) To find the probability that a woman has a blood pressure less than 108, we follow a similar process. The z-score is (108 - 116) / 9 = -0.8889. Using the standard normal distribution table or calculator, we find that the probability corresponding to a z-score of -0.8889 is approximately 0.3121. Therefore, the probability of having a blood pressure less than 108 is 0.3121.

(c) To find the probability of the blood pressure falling between 108 and 124, we calculate the z-scores for both values. The z-score for 108 is (-8) / 9 = -0.8889, and the z-score for 124 is (124 - 116) / 9 = 0.8889. Using the standard normal distribution table or calculator, we find the corresponding probabilities for these z-scores, which are 0.3121 and 0.8121, respectively. To find the probability of falling between these two values, we subtract the smaller probability from the larger one, giving us 0.8121 - 0.3121 = 0.5. Therefore, the probability of having a blood pressure between 108 and 124 is 0.5, or 0.4772 when rounded to four decimal places.

Constructive responses to job satisfaction involve addressing concerns, providing support, and promoting a positive work environment.

Job satisfaction refers to an individual's level of contentment and fulfillment with their job. It is influenced by various factors such as work environment, compensation, relationships with colleagues, opportunities for growth, and alignment with personal values.

When employees experience job dissatisfaction, they may respond in different ways. One possible response is neglect, which refers to a passive and disengaged attitude towards work. Neglectful employees may become indifferent, withdraw their effort, or mentally check out from their responsibilities.

To increase the number of interviews, it should be recommended that 0 undergraduate students, 16 graduate students, and 4 faculty members be hired. There can be a maximum of 644 interviews by statistics

In 1947, George Dantzig invented an algorithm that allows us to take a system of equations and find its maximum or minimum values that make the equations most efficient. This method is used in linear programming to determine optimization.

If n = the number of interviews, then let x = the number of undergraduate students hired, y = the number of graduate students employed, z = the number of faculty members hired.

Maximization of n = 30x + 32y + 33z

The limitations are: x + y + z 20; 100x + 150y + 200z 3200; and 0;
