In paragraph 9, why does Paul Ryan tell his audience that he represents "a part of America that includes inner cities, rural areas, suburbs, and factory towns"?

Percentage for the runners with heart rate of above 140 is 50.199% probability.

To calculate percentage of runners heart rate;

Mean, μ = 104

Standard deviation, σ = 12.5

Probability = P(X > 140)

P(X > 140) = [tex]1 - P (\frac{X - μ}{σ} \leq \frac{140 - μ}{σ})[/tex]

P(X > 140) = [tex]1 - P (Z \leq \frac{140 - 104}{12.5})[/tex]

P(X > 140) = [tex]1 - P (Z \leq \ 2.88)[/tex]

For a Z score of 2.88, the cumulative from mean probability and percentile are:

The normal distribution for 2.88 = 0.49801

P(X > 140) = 1 - 0.49801

P(X > 140) = 0.50199

P(X > 140) = 0.50199 x 100

The percentage for the heart rate = 50.199%

The probability of of runners heart rate above 140 is a 50.199% chance.

Answer:

Sports figures and celebrities have long been viewed as positive role models for many people. On the one hand, they have the power to inspire and motivate others to achieve their goals, as well as provide a sense of belonging to those who look up to them. For example, athletes can demonstrate the importance of hard work, dedication, and discipline needed to succeed in any field. Furthermore, celebrities can show that one can become successful despite their background or circumstances. On the other hand, there are some drawbacks to viewing sports figures and celebrities as role models. For example, they often live extravagant lifestyles and may not be the best examples of how to handle money responsibly. Additionally, their behavior may not be the best representation of the values that should be instilled in young people. Ultimately, while sports figures and celebrities can be inspiring, it is important to remember that they should not be viewed as role models in all aspects of life.

Explanation:

A. The 90% confidence interval for the population mean is (162.91,167.09)

B. The value Margin of error is 7.42

C. The interpretation of the confidence level obtain from (a) is there is a 90% chance that the interval (162.91,167.09) contains the true population mean.

a) A 90% confidence interval for the population mean can be constructed using the following formula:

(sample mean) ± (critical value) x (standard deviation of the mean)

The critical value is determined by the level of confidence and the sample size. For a 90% confidence level and a sample size of 20, the critical value is 1.645.

Therefore, the 90% confidence interval for the population mean is:

165 ± (1.645 x 4.5)

which is (162.91,167.09)

b) The margin of error is the critical value x the standard deviation of the mean, or 1.645 x 4.5 = 7.42.

c) A 90% confidence interval means that if we were to repeat this process many times, 90% of the intervals constructed would contain the true population mean. In other words, there is a 90% chance that the interval (162.91,167.09) contains the true population mean.

Therefore, the correct answer is as given above. It can then be concluded that the values given for 90% confidence interval, margin of error and it's interpretation are as given.

A boat heading out to sea starts out at Point AA, at a horizontal distance of 1023 feet from a lighthouse/the shore. The distance from point AA to point BB is  -1114.01 feet.

Distance is a numerical or qualitative measurement of the distance between two objects or places.

The distance of point A from the lighthouse = 1023 feet

The angle of elevation from point A to the lighthouse = 11°

The angle of elevation from point B to the lighthouse = 2°

tanΘ = opposite side to angle / adjacent side to the angle

tan7° = height from sea to the lighthouse / 1023 feet

Height to the lighthouse = tan(11°) × 1023 feet

0.1944 x  1023 feet =  198.8712

For point B

tan3° = 198.8712 feet

Horizontal distance =  198.8712 / tan3°

tan3° = -2.1850

Horizontal distance =  198.8712 / -2.1850 = -91.0165

D = Horizontal distance from B to LH - Horizontal distance from A to LH

Distance from A to B

-91.0165 - 1023 feet =  -1114.01

Therefore, the distance from point AA to point BB is  -1114.01 feet.

Answer: oxygen

Explanation:

The error variance can be Illustrated as σ^2 = E(μ^2) = Var(μ) = (1/n) * ∑(y - (b0 + b1x))^2

The simple linear regression model is of the form:

y = b₀ + b₁x + μ

y = the dependent variable

x = the independent variable

b₀ and b₁ = the parameters of the model, and μ is the error term.

The error term represents the difference between the observed value of the dependent variable and the value predicted by the model. In other words, it is the deviation of the observed y from the expected value of y, given the value of x.

The error variance, denoted by σ^2, is a measure of the spread of the error term. It is calculated as the average squared deviation of the error term from its mean value, which is zero:

σ^2 = E(μ^2) = Var(μ) = (1/n) * ∑(y - (b₀ + b₁x))^2

The central bank of a country controls the amount of money in circulation in order to maintain the health of the economy. Banks can regulate the amount of money in circulation by manipulating interest rates.

Economic and financial stability is largely dependent on central banks. In order to achieve low and stable inflation, they implement monetary policy. Following the global financial crisis, central banks have added more tools to their arsenals to address threats to financial stability and control fluctuating exchange rates.

In developing nations, a central bank can be extremely important in creating the financial foundation for growth. A clear and significant activity that falls under this category is the development of local currency and the capital market.
