This is a standard result.

The statement that best describes the distribution is C. The data is normally distributed because the majority of the data is in the center.

A histogram is a graphical representation of data points organized into ranges that the user specifies. The histogram, which resembles a bar graph in appearance, condenses a data series into an easily interpreted visual by grouping many data points into logical ranges or bins.

Because the majority of the data is in the center, the data is normally distributed.

Data in a normal distribution are symmetrically distributed and have no skew. The majority of values cluster around a central region, with values decreasing as one moves away from the center. In a normal distribution, the measures of central tendency (mean, mode, and median) are identical.

The required age of the bone is approximately 8,200 years.

To estimate the age of a bone that now contains 70% of its original amount of carbon-14, you can use the formula:

age = (half-life / log(2)) x log(original amount / current amount)

In this case, the original amount of carbon-14 is 100% and the current amount is 70%, so the age of the bone can be calculated as:

age = (5730 years / log(2)) x log(100% / 70%)

age = (5730 years / 0.693) x 0.35667

age = 8268 years

Rounded to the nearest 100 years,

age = 8200 years

Therefore, the bone is estimated 8,200 years old.

Answer:

The correct answer is C) Completing the square.

Step-by-step explanation:

In the first step of the derivation, the left-hand side of the equation is the standard form of a quadratic equation, with the variable x raised to the second power and the coefficient of x being 1. In the second step, the expression on the left-hand side is rewritten as the square of a binomial, with the constant term b/2a added to the binomial. This process of adding the constant term and then squaring the resulting binomial is called "completing the square." By completing the square, it is possible to rewrite the original quadratic equation in a form that can be easily solved using the quadratic formula.

There are 3 blue sectors out of the total 10.

The coordinates of A' = (1, 7)

The coordinates of B' = (4, 9)

The coordinates of C' = (3, 6)

There are two ways of translation.

Along x-axis:

Along y-axis:

(x, y) - (-x, y)

We have,

ΔABC:

Coordinates:

A = (2, 3)

B = (5, 1)

C = (4, 4)

Reflection across y = 5.

So,

A = (2, 5)

There are two units between y = 5 and y = 3.

We add 2 units with the y-coordinate of A = (2, 5)

5 - 3 = 2

So,

A = (2, 5 + 2)

A = (2, 7)

Similarly,

5 - 1 = 4

B = (5, 5 + 4) = (5. 9)

5 - 4 = 1

C = (4, 5 + 1) = (4. 6)

Translation of 1 unit down.

A = (2 - 1, 7) = (1, 7)

B = (5 - 1, 9) = (4, 9)

C = (4 - 1, 6) = (3, 6)

Let the number be x.

Set equation for x and solve:

Answer:

3. (x | x > 5)

Step-by-step explanation:

To solve this inequality, we need to isolate the variable on one side and the constant on the other side. To do this, we need to use the properties of inequalities and the order of operations to manipulate the given inequality into a form we can solve.

First, we need to distribute the coefficients in front of the parentheses on the left-hand side of the inequality. This gives us:

4x - 12 - 2x + 2 > 0

Next, we can combine like terms on the left-hand side of the inequality by adding the terms with the variable and subtracting the constant terms. This gives us:

2x - 10 > 0

Now, we have isolated the variable on one side of the inequality and the constant on the other side. To solve the inequality, we need to determine the values of x that make the inequality true.

To do this, we can divide both sides of the inequality by the coefficient of the variable, which gives us:

x - 5 > 0

This inequality is satisfied when x is greater than 5. Therefore, the solution to the original inequality is x > 5.

We calculated the required interval is 13.341 and 11.46 to estimate true average.

It is a statistical term that express that the value of a specific parameter located within a boundary.

A statistical expression that has upper and lower limit. This value gives assurances to the average or mean value to be within the limit.

Given, number of samples, n =25

sample standard deviation, σ = 2.4%

average tip = sample mean, X = 12.4%

confidence level =95%

We need to construct an interval to estimate the true average tip with 95% confidence level.

We know that confidence level value Zc for 95% = 1.96

Now, confidence interval CI = X±Zc (σ/√n)

                   by putting the given value, CI= 12.4±1.96(2.4/√25)

The test statistic used to compare the variability of the wind speeds at two proposed sites for the new wind-based power plant is the F-test. The F-test is used to determine if the two population variances are equal. To calculate the test statistic, the standard deviation for each sample is squared and divided. For this example, the test statistic is 0.41. To determine the rejection region at the 10% significance level, the critical value must be calculated. The critical value is 1.878, so the rejection region is TS < -1.878 or TS > 1.878. If the test statistic falls outside of the rejection region, then the null hypothesis is rejected and the two population variances are not equal.

The margin of error at 95% confidence is 0.046., the 95% confidence interval of the population proportion of people who would pay off debts with an unexpected tax refund is (0.424, 0.516).

The margin of error is a statistical measure of the variability of a sample statistic from its population value. It is calculated by taking the standard error of the statistic and dividing it by the sample size. It is typically expressed as a percentage and is used to measure the precision of the sample statistic compared to the population statistic. Margin of error is primarily used in confidence intervals to measure the accuracy of survey results. It is also used to measure the impact of random sampling error on the statistical significance of the results.

a. Margin of Error: The margin of error is calculated using the formula Margin of Error = z* (√p*(1-p)/n), where z is the z-score for the 95% confidence interval (1.96), p is the sample proportion (0.47), and n is the sample size (1,026).
Plugging in the values, we get Margin of Error = 1.96 * (√0.47*(1-0.47)/1,026) = 0.046.
Therefore, the margin of error at 95% confidence is 0.046.

b. Confidence Interval: The confidence interval is calculated using the formula Confidence Interval = (p-margin of error, p+margin of error), where p is the sample proportion (0.47) and margin of error is the margin of error (0.046).
Plugging in the values, we get Confidence Interval = (0.47 - 0.046, 0.47 + 0.046) = (0.424, 0.516).

Therefore, the 95% confidence interval of the population proportion of people who would pay off debts with an unexpected tax refund is (0.424, 0.516).
