if 10% of a group of children are girls, what is the ratio of girls to boys​

To find the vertical asymptotes of a rational function, we need to set the denominator equal to zero and solve for x.

To find the vertical asymptotes of a rational function, you need to determine the values of x that make the denominator of the function equal to zero.

Let's check the limit of our example function as x approaches each of the vertical asymptotes:

As x approaches 1 from the left side: f(x) approaches negative infinity

As x approaches 1 from the right side: f(x) approaches positive infinity

Therefore, x = 1 is a valid vertical asymptote.

As x approaches 3 from the left side: f(x) approaches positive infinity

As x approaches 3 from the right side: f(x) approaches negative infinity

Therefore, x = 3 is also a valid vertical asymptote.

The values of x that make the denominator zero are the vertical asymptotes of the function.

For every minute, the oven's temperature will increase by 18 degrees. Therefore, the oven will heat up by 18 degrees in 1 minute.

To find out how much the oven will heat up in 1 minute, we need to determine the rate at which the temperature rises. Given that the oven's temperature rose 3 degrees in 1/6 of a minute, we can calculate the rate of change.

To do this, we divide the temperature rise (3 degrees) by the time taken (1/6 minute):

Rate of change = 3 degrees / (1/6 minute)

= 3 degrees * (6/1 minute)

= 18 degrees per minutes,

the oven will heat up by 18 degrees in 1 minute. The oven will heat up by 18 degrees in 1 minute. When Mr. Cameron preheated his oven, the oven's temperature rose by 3 degrees in 1/6 of a minute. This information allows us to determine the rate of change or how much the temperature increases per minute.

To find the rate of change, we need to divide the temperature rise by the time taken. In this case, the temperature rise is 3 degrees, and the time taken is 1/6 of a minute. Dividing 3 degrees by 1/6 minute, we get a rate of change of 18 degrees per minute. This means that for every minute, the oven's temperature will increase by 18 degrees. Therefore, the oven will heat up by 18 degrees in 1 minute.

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Given

x² - 7x - 44

Consider the factors of the constant term (- 44) which sum to give the coefficient of the x- term (- 7)

The factors are - 11 and + 4 , since

- 11 × 4 = - 44 and - 11 + 4 = - 7 , thus

x² - 7x - 44 = (x - 11)(x + 4) ← in factored form

with (x - 11) as a factor → B

P-value is greater than the significance level, we fail to reject the null hypothesis, suggesting that there is not enough evidence to conclude that concerns for global warming have decreased.

To determine if concerns for global warming have decreased since 2011 based on the sample from 2014, we can perform a hypothesis test.

The null hypothesis (H₀) states that there is no difference in the proportion of people concerned about global warming between 2011 and 2014, while the alternative hypothesis (H₁) states that there is a decrease in the proportion of people concerned.

H₀: p₁ = p₂ (the proportion in 2011 is equal to the proportion in 2014)

H₁: p₁ > p₂ (the proportion in 2011 is greater than the proportion in 2014)

To perform the test, we calculate the test statistic, which follows a standard normal distribution under the null hypothesis. The test statistic formula is:

z = (p₁ - p₂) / sqrt(p(1-p)(1/n₁ + 1/n₂))

where p₁ is the sample proportion in 2011, p₂ is the sample proportion in 2014, p is the combined sample proportion, n₁ is the sample size in 2011, and n₂ is the sample size in 2014.

Given that p₁ = 0.56, p₂ = 0.52, n₁ = n₂ = 1336, and using the formula, we can calculate the test statistic z.

The P-value is then calculated as the probability of observing a test statistic as extreme as the calculated z, assuming the null hypothesis is true. We compare the P-value to a significance level (e.g., 0.05) to determine if we reject or fail to reject the null hypothesis.

If the P-value is less than the significance level, we reject the null hypothesis, indicating that there is evidence that concerns for global warming have decreased since 2011.

Trigonometric Ratios are defined as the values of all the trigonometric functions based on the value of the ratio of sides in a right-angled triangle.

In a right angle triangle, the longest side is called the hypotenuse and the other two sides are called opposite and adjacent. The line facing the acute angle( tetha) is the opposite. The ratio of the sides with the acute angle are called trigonometric ratio.

sin(tetha) = opp/ hyp

cos( tetha) = adj/ hyp

tan(tetha) = opp/adj

In the triangle, using angle C,

opposite = 4

adjascent = 3 and hypotenuse = 5

cos (C) = 3/5

therefore the value of cos (C) = 3/5

The six main criteria to define normality and abnormality include statistical infrequency, personal distress, others' distress, unexpected behavior, highly consistent/inconsistent behavior, and maladaptiveness/disability.

1. Abnormality as statistical infrequency: This criterion defines abnormality based on behaviors or characteristics that deviate significantly from the statistical norm.

2. Abnormality as personal distress: This criterion focuses on the individual's subjective experience of distress or discomfort. It considers behaviors or experiences that cause significant emotional or psychological distress to the person as abnormal.

For instance, someone experiencing intense anxiety or depression may be considered abnormal based on personal distress.

3. Abnormality as others' distress: This criterion takes into account the impact of behavior on others. It considers behaviors that cause distress, harm, or disruption to others as abnormal.

For example, someone engaging in violent or aggressive behavior that harms others may be considered abnormal based on the distress caused to others.

4. Abnormality as unexpected behavior: This criterion defines abnormality based on behaviors that are considered atypical or unexpected in a given context or situation.

For instance, if someone starts laughing uncontrollably during a sad event, their behavior may be considered abnormal due to its unexpected nature.

5. Abnormality as highly consistent/inconsistent behavior: This criterion involves comparing an individual's behavior to both their own typical behavior and the behavior of others. Consistent or inconsistent patterns of behavior may be considered abnormal.

For example, if a person consistently engages in risky and impulsive behavior, it may be seen as abnormal compared to their own usually cautious behavior or the behavior of others in similar situations.

6. It considers behaviors that are maladaptive, causing difficulties in personal, social, or occupational areas. For instance, someone experiencing severe social anxiety that prevents them from forming relationships or attending school or work may be considered abnormal due to the disability it causes.

The medical model and classification systems used in physical illnesses have both value and limitations when applied to psychological disorders. They provide a structured framework for understanding and diagnosing psychological disorders, allowing for standardized assessment and treatment. However, they can oversimplify the complexity of psychological experiences and may lead to overpathologization or stigmatization.

The p-value he obtains and the general conclusion that can be made at a 99% significance level is 0.01

A p-value is a measure of the evidence against a null hypothesis. In this case, the null hypothesis is that the coin is fair and equally likely to turn up heads or tails.

The coach carries out a significance test to determine if the number of tails in his trial of 100 flips is significantly different from what would be expected if the coin were fair.

The p-value is calculated by comparing the observed number of tails (35) to the expected number of tails (50, if the coin were fair) using a binomial distribution.

This involves finding the probability of observing 35 or fewer tails in 100 flips, assuming the null hypothesis is true. If this probability is low (i.e. if the p-value is small), then it suggests that the coin is not fair and that the observed difference is unlikely to have occurred by chance.

At a 99% significance level, a common threshold used in statistical tests, the p-value needs to be less than 0.01 to reject the null hypothesis and conclude that the coin is not fair.

If the p-value obtained is less than 0.01, then we can conclude with 99% confidence that the coin is biased towards heads. On the other hand, if the p-value is greater than 0.01, then we fail to reject the null hypothesis and conclude that there is not enough evidence to say that the coin is unfair.

The standard deviation of the return on Portfolio1 invested 40% in Stock 1 and 60% in Stock 2 is 0.83%.

To calculate the expected return of Portfolio1, we can use the formula:

Expected return of Portfolio1 = (Weight of Stock 1 x Rate of return of Stock 1) + (Weight of Stock 2 x Rate of return of Stock 2)

Using the given information, we have:

Expected return of Portfolio1 = (0.4 x 3%) + (0.6 x 8%) = 1.2% + 4.8% = 6%

Therefore, the expected return of Portfolio1 invested 40% in Stock 1 and 60% in Stock 2 is 6%.

To calculate the standard deviation of the return on Portfolio1, we need to calculate the variance first. The variance formula for a portfolio is:

\(Variance of Portfolio1 = (Weight of Stock 1)^2 x Variance of Stock 1 +\)\((Weight of Stock 2)^2 x Variance of Stock 2 + 2 x Weight of Stock 1\) \(x Weight of Stock 2 x Covariance between Stock 1 and Stock 2\)

The covariance between Stock 1 and Stock 2 can be calculated using the formula:

\(Covariance between Stock 1 and Stock 2 = Correlation between Stock 1\) and\(Stock 2 x Standard deviation of Stock 1 x Standard deviation of Stock 2\)

The correlation between Stock 1 and Stock 2 is not given, so we assume it to be 0. This means that the returns of Stock 1 and Stock 2 are not correlated with each other.

Using the given information, we have:

Variance of Stock 1 = (0.2 x (3% - 6%)^2) + (0.8 x (10% - 6%)^2) = 0.68%

Variance of Stock 2 = (0.2 x (2% - 6%)^2) + (0.8 x (8% - 6%)^2) = 1.44%

Covariance between Stock 1 and Stock 2 = 0 x SQRT(0.68%) x SQRT(1.44%) = 0

Using these values, we can calculate the variance of Portfolio1:

Variance of Portfolio1 = (0.4)^2 x 0.68% + (0.6)^2 x 1.44% + 2 x 0.4 x 0.6 x 0 = 0.696%

Finally, the standard deviation of Portfolio1 can be calculated by taking the square root of the variance:

Standard deviation of Portfolio1 = SQRT(0.696%) = 0.83%

Therefore, the standard deviation of the return on Portfolio1 invested 40% in Stock 1 and 60% in Stock 2 is 0.83%.
