In a survey of 2,800 people who owned a certain type of​ car 1,120 said they would buy that type of car again. What percent of the people surveyed were satisfied with the​ car?

The statistic is 101 out of 152 (66.45%) which  the questionnaires returned from the 800 mailed support the enactment of a statewide smoking ban in all enclosed public places.

To calculate this statistic, I first found the total number of questionnaires returned, which was 152. I then found the number of questionnaires that supported the ban, which was 101. To calculate the percentage, I then divided the number of questionnaires that supported the ban (101) by the total number of questionnaires returned (152), which gave me the answer of 66.45%. This percentage shows that a majority of the voters in the state representative's district support the enactment of a statewide smoking ban in all enclosed public places.

The main idea behind statistical inference is that through the use of sample data, we are able to draw conclusions about the population from which the data was drawn (option c).

Statistical inference allows us to make inferences and draw conclusions about a larger population based on the analysis of a smaller representative sample.

By collecting data from a sample, we can use statistical methods to analyze and summarize the information. These methods include estimating population parameters, testing hypotheses, and making predictions.

The key assumption underlying statistical inference is that the sample is representative of the larger population, allowing us to generalize the findings to the population as a whole.

Statistical inference provides a way to make reliable and informed decisions, identify patterns and relationships, and make predictions about future observations based on the available data. It allows researchers, scientists, and decision-makers to make evidence-based conclusions and draw meaningful insights from limited observations.

There are 13 diamonds in the deck (as well as other colors). Since there are 52 cards, the probability of getting a diamond on the first draw is 13/52. After the first card is drawn, all that's left are his 12 diamonds. Therefore, the probability of drawing a diamond is 12/51 (note that he has only 51 cards left after pulling/removing the first card since there are no replacement cards). The overall probability is the product of two possibilities. The odds of drawing diamonds from the original deck are 13/52 times the odds of drawing diamonds from his remaining 51 cards. Assuming the first card drawn is a diamond, 12/51.

P=13/52*12/51=1/4*4/17=1/17.

The transitive property of equality completes the proof.

The transitive property of equality is used to complete the proof.

The transitive property states that if two quantities are equal to the same quantity, then they are equal to each other. In other words, if A = B and B = C, then A = C. This property allows us to establish a chain of equalities and draw conclusions based on the relationships between multiple quantities.

In the context of the given proof, the transitive property is likely used to connect multiple equalities or statements, showing the logical progression of the proof. By applying the transitive property, the proof can establish a clear and valid argument.

the ordered pair will be (3,-1) lies in the inverse function.

What is inverse function?

A function that returns the initial value for which a function has produced output is called an inverse function. If f(x) is a function that produces the value y, then f-1(y), which is the inverse function of y, will produce the value x. Inverse and reciprocal functions should not be confused. The output's original value is returned by the function's inverse, which is represented by the symbol f-1 (x). While the reciprocal of a function is represented by 1/f(x) or f(x)-1

Those that do are referred to as invertible. For a function f: X Y to have an inverse, it must possess the characteristic that there is exactly one x in X such that f(x) = y for every y in Y. This characteristic guarantees the existence of a function g: Y X that has the required connection to f.

function g(x)=∛(x−4)

So the inverse of the function

g ¬(x) = x³+4

So the ordered pair will be (3,-1)

We can conclude that the equation has exactly one real root (namely, x = 0) and two complex conjugate roots.

What is the quadratic equation?

The solutions to the quadratic equation are the values of the unknown variable x, which satisfy the equation. These solutions are called roots or zeros of quadratic equations. The roots of any polynomial are the solutions for the given equation.

I can give an example to demonstrate how to use inspection and Descartes' rule to find a real root of an equation and show that there are no other real roots.

Consider the equation x³ - 3x² + 2x = 0. By inspection, we can see that x = 0 is a real root of the equation since the left-hand side of the equation evaluates to 0 when x = 0.

To use Descartes' rule, we need to count the number of sign changes in the coefficients of the polynomial f(x) = x³ - 3x²  + 2x.

There are two sign changes: from positive to negative in the coefficient of x² and from negative to positive in the constant term.

Therefore, according to Descartes' rule, the equation has either two or zero positive real roots.

Next, we need to count the number of sign changes in the coefficients of f(-x), which is obtained by replacing x with -x in f(x).

We have f(-x) = -x³ - 3x² - 2x, which has one sign change: from negative to positive in the coefficient of x².

Therefore, according to Descartes' rule, the equation has either one or three negative real roots.

Since the total number of positive and negative real roots must add up to the degree of the polynomial (which is 3 in this case),

Hence, we can conclude that the equation has exactly one real root (namely, x = 0) and two complex conjugate roots.

To utilize the gross profit method, the following information is needed:

1. Beginning Inventory: The value of inventory at the beginning of the accounting period is required.

It represents the cost of inventory available for sale before any purchases or sales occur.

2. Net Sales: The total amount of sales made during the accounting period, excluding any sales returns, allowances, or discounts.

3. Gross Profit Percentage: The gross profit percentage is calculated by dividing the gross profit by net sales. It represents the proportion of net sales that contributes to covering the cost of goods sold.

4. Ending Inventory: The value of inventory at the end of the accounting period is necessary. It represents the cost of unsold inventory that remains on hand.

By using the gross profit percentage, the method allows for estimating the cost of goods sold (COGS) during the accounting period based on the net sales and the desired gross profit percentage. The estimated COGS can then be subtracted from the beginning inventory to determine the estimated ending inventory.

The equation to determine the number of years it will take for the price per kilowatt-hour to reach $0.10 is t = ln(2) / ln(1.0205). In this case, A = 0.05, b = 2, and c = 1.0205.

To create the equation that can be used to determine how many years it will take for the price per kilowatt-hour to reach $0.10, we can use the formula for exponential growth.

The formula for exponential growth is given by:

y = A * (1 + r)^t

Where:

- y is the final value we want to reach ($0.10 in this case).

- A is the initial value ($0.05 in this case).

- r is the growth rate per period (2.05% annually, which is 0.0205 as a decimal).

- t is the number of periods (the number of years after 1979).

Substituting the given values into the equation, we get:

0.10 = 0.05 * (1 + 0.0205)^t

Simplifying the equation, we have:

2 = (1.0205)^t

Now, to solve for t, we can take the natural logarithm of both sides of the equation:

ln(2) = ln(1.0205)^t

Using logarithmic properties, we can bring the exponent t down:

ln(2) = t * ln(1.0205)

Finally, we can solve for t by dividing both sides of the equation by ln(1.0205):

t = ln(2) / ln(1.0205)

Therefore, the equation to determine the number of years it will take for the price per kilowatt-hour to reach $0.10 is t = ln(2) / ln(1.0205). In this case, A = 0.05, b = 2, and c = 1.0205.

Answer:

A i think

Step-by-step explanation:

The critical value of t for constructing a 99% confidence interval with a sample size of 30 and a sample standard deviation of 0.05 is 2.7564.

A confidence interval is a range of values within which the population parameter is estimated to lie with a certain level of confidence. In this case, we are constructing a 99% confidence interval for the population mean. The critical value of t is used to determine the width of the confidence interval.

The formula for calculating the confidence interval for the population mean is:

Confidence interval = sample mean ± (critical value) * (standard deviation of the sample / square root of the sample size)

Given that the sample size is 30 (n = 30) and the standard deviation of the sample is 0.05 (S = 0.05), we need to find the critical value of t for a 99% confidence level. The critical value of t depends on the desired confidence level and the degrees of freedom, which is equal to n - 1 in this case (30 - 1 = 29). Looking up the critical value in a t-table or using statistical software, we find that the critical value of t for a 99% confidence level with 29 degrees of freedom is approximately 2.7564.

Therefore, the 99% confidence interval for the population mean would be calculated as follows: sample mean ± (2.7564) * (0.05 / √30). The final result would be a range of values within which we can be 99% confident that the true population mean lies.

Step-by-step explanation:

Using the rules of exponents

\(\frac{a^{m} }{a^{n} }\) ⇔ \(a^{(m-n)}\) ( m > n)

\(\frac{a^{m} }{a^{n} }\) ⇒ \(\frac{1}{a^{(n-m)} }\) ( n > m )

Given

\(\frac{21x^6y^5}{14x^2y^9}\)

= \(\frac{21}{14}\) × \(x^{(6-2)}\) × \(\frac{1}{y^{(9-5)} }\)

= \(\frac{3}{2}\) × \(x^{4}\) × \(\frac{1}{y^{4} }\)

= \(\frac{3x^4}{2y^4}\) ← with positive exponents
