Emily runs at the fastest speed of 15 ft per second, Liz runs at 13.03 ft per second, and Zack runs at 12.8 ft per second.

Speed is defined as the ratio of the time distance travelled by the body to the time taken by the body to cover the distance. Speed is the ratio of the distance travelled by time. The unit of speed in miles per hour.

Given that Emily runs 15 ft per second no one runs 358 ft and 36 seconds Liz runs 1 mi in 405 seconds Zack runs 768 feet in 1 minute.

Emily's speed = 15 ft/sec

Liz's speed = 1 mile per 405 sec = 5280/405 = 13.03 ft /sec

Zack's speed = 768 / 60 = 12.8 ft /sec

Therefore, Emily runs at the fastest speed of 15 ft per second, Liz runs at 13.03 ft per second, and Zack runs at 12.8 ft per second.

In this study, where each subject participates in all three treatments, randomization can still be incorporated in the following ways:

The goal of randomization is to assign participants to different treatments in a way that balances any potential confounding variables that may influence the outcome of the study.

a. Randomize which subject is given each treatment: In this approach, subjects would be randomly assigned to one of the three treatments.

b. Randomize the order of the treatments being administered for each subject: In this approach, the order of treatments would be randomly assigned for each subject.

c. Randomize the number of treatments each subject receives: In this approach, some participants would receive two treatments while others would receive all three. Randomization would ensure that there is an equal number of participants in each group.

d. Effective randomization cannot be attained: If randomization is not possible due to ethical or logistical issues, the study could still be conducted with a pre-post design. In this design, each participant would receive all three treatments, but the order of the treatments would be fixed.

The chi-square goodness-of-fit test can provide important information about whether the observed data significantly deviates from the expected distribution, which categories or bins contribute to the deviation, and the overall goodness-of-fit of the data to the expected distribution.

The chi-square goodness-of-fit test is a statistical test used to determine if a sample of data comes from a population with a specific distribution. Specifically, the test compares the observed frequencies of data in different categories or bins with the expected frequencies of data in those categories based on a hypothesized distribution.

It can determine whether the observed data significantly deviates from the expected distribution. If the test results in a p-value less than the chosen level of significance, it indicates that the observed data significantly deviates from the expected distribution, and the null hypothesis (that the data follows the expected distribution) can be rejected.

It can identify which categories or bins contribute the most to any significant deviation. The test statistic and associated p-value can help to identify which categories or bins show significant differences between the observed and expected frequencies.

It can provide information on the overall goodness-of-fit of the data to the expected distribution. The test statistic provides a measure of the overall goodness-of-fit, with higher values indicating greater deviation from the expected distribution.

A z-score of -2 indicates that the sample mean does not occur very often by chance in the sampling distribution of means and probably did not come from the given population.

To answer this question, we need to calculate the z-score of the sample mean. The formula for the z-score is (sample mean - population mean) / standard error.

Plugging in the values given, we get:

z = (80 - 100) / 10 = -2

A z-score of -2 indicates that the sample mean is 2 standard errors below the population mean.

Based on this information, we can conclude that the sample mean does not occur very often by chance in the sampling distribution of means, and probably did not come from the given population.

This is because the z-score is beyond the typical range of values we would expect to see if the sample mean came from the population.

In this case, you have a random sample with a mean of 80, while the population mean is 100, and the standard error is 10.

To calculate the z-score, use the formula: (sample mean - population mean) / standard error, which is (80-100)/10 = -20/10 = -2.

Total stockholders’ equity 7,800,000

Statement of stockholders’ equity for CC for the year ended December 31, 2012:Particulars Amount ($)
Common Stock 100,000

Additional Paid-in Capital 4,100,000
Retained Earnings (Opening Balance) 3,000,000
Add: Net Income for the year ended December 31, 2012 800,000
Total retained earnings 3,800,000

Less: Cash Dividend Declared on July 1 and paid on July 31 (200,000)
Retained earnings (Closing balance) 3,600,000
Total stockholders’ equity 7,800,000

Explanation:The given information is as follows:Common Stock on January 1, 2012 = $100,000Additional Paid-in Capital on January 1, 2012 = $4,100,000

Retained Earnings on January 1, 2012 = $3,000,000Net Income for the year ended December 31, 2012 = $800,000Cash Dividend Declared on July 1 and paid on July 31 = $200,000

To prepare the statement of stockholders’ equity for the year ended December 31, 2012, we will begin by preparing the opening balances of each of the equity accounts. We will then add the net income to the retained earnings account.

The closing balance for retained earnings is then computed by subtracting the cash dividend declared and paid from the total retained earnings. Finally, the total stockholders' equity is calculated by adding the balances of all the equity accounts.

Calculations:Opening balance of common stock = $100,000

Opening balance of additional paid-in capital = $4,100,000

Opening balance of retained earnings = $3,000,000

Net Income for the year ended December 31, 2012 = $800,000

Retained earnings (Opening Balance) = $3,000,000

Add: Net Income for the year ended December 31, 2012 = $800,000

Total retained earnings = $3,800,000Less: Cash Dividend Declared on July 1 and paid on July 31 = $200,000Retained earnings (Closing balance) = $3,600,000

Total stockholders’ equity = Common Stock + Additional Paid-in Capital + Retained Earnings (Closing balance) = $100,000 + $4,100,000 + $3,600,000 = $7,800,000

Therefore, the statement of stockholders’ equity for CC for the year ended December 31, 2012, is as follows:Particulars Amount ($)
Common Stock 100,000
Additional Paid-in Capital 4,100,000

Retained Earnings (Opening Balance) 3,000,000
Add: Net Income for the year ended December 31, 2012 800,000
Total retained earnings 3,800,000

Less: Cash Dividend Declared on July 1 and paid on July 31 (200,000)

Should there be a global effort to sharply reduce the cutting and burning of old-growth forests?

Yes, there should be a global effort to sharply reduce the cutting and burning of old-growth forests. Old-growth forests are vital ecosystems that provide numerous environmental, social, and economic benefits. They are home to diverse species, including endangered ones, and play a crucial role in carbon sequestration, mitigating climate change, and preserving biodiversity.

Cutting and burning old-growth forests contribute to deforestation, habitat loss, and greenhouse gas emissions. It disrupts ecosystems, threatens species survival, and exacerbates climate change. Protecting old-growth forests is essential for maintaining ecological balance and promoting sustainable development.

Numerous references and scientific studies support the importance of preserving old-growth forests. Some relevant sources include:

(a) The vectors $3-x+4x^2$, $2+5x+2x^2$, and $2+3x-4x^2$ are linearly dependent in $P_2$.

(b) The vectors $1+3x+5x^2$, $x+6x^2$, $6+2x+5x^2$, and $8+3x-x^2$ are linearly independent in $P_2$.

(a) To determine the linear dependence of the vectors $3-x+4x^2$, $2+5x+2x^2$, and $2+3x-4x^2$, we need to check if there exist constants $c_1$, $c_2$, and $c_3$ (not all zero) such that $c_1(3-x+4x^2) + c_2(2+5x+2x^2) + c_3(2+3x-4x^2) = 0$. By comparing the coefficients of $x^2$, $x$, and the constant terms, we obtain the system of equations:

$4c_1 + 2c_2 - 4c_3 = 0$

$0c_1 + 5c_2 + 3c_3 = 0$

$3c_1 + 2c_2 + 2c_3 = 0$

Solving this system, we find that $c_1 = -2$, $c_2 = 1$, and $c_3 = -1$, which are not all zero. Therefore, the vectors are linearly dependent.

(b) To determine the linear independence of the vectors $1+3x+5x^2$, $x+6x^2$, $6+2x+5x^2$, and $8+3x-x^2$, we need to check if there exist constants $c_1$, $c_2$, $c_3$, and $c_4$ such that $c_1(1+3x+5x^2) + c_2(x+6x^2) + c_3(6+2x+5x^2) + c_4(8+3x-x^2) = 0$. By comparing the coefficients of $x^2$, $x$, and the constant terms, we obtain the system of equations:

$5c_1 + 6c_2 + 5c_3 - c_4 = 0$

$3c_1 + c_2 + 2c_3 + 3c_4 = 0$

$c_1 + 6c_2 + 0c_3 - c_4 = 0$

Solving this system, we find that $c_1 = 0$, $c_2 = 0$, $c_3 = 0$, and $c_4 = 0$. Therefore, the vectors are linearly independent.

The 90% confidence interval for the difference in the population means is -2.51 to 0.31

From the question, we have the following parameters that can be used in our computation:

xˉ₁ = −17.1

s₁² = 8.4

n₁ = 22

​xˉ₂ = −16.0

s₂² = 8.7

n₂ = 24

Calculate the pooled variance using

P = (df₁ * s₁² + df₂ * s₂²)/df

Where

df₁ = 22 - 1 = 21

df₂ = 24 - 1 = 23

df = 22 + 24 - 2 = 44

So, we have

P = (21 * 8.4 + 23 * 8.7)/44

P = 8.56

Also, we have the standard error to be

SE = √(P/n₁ + P/n₂)

So, we have

SE = √(8.56/22 + 8.56/24)

SE = 0.86

The z score at 90% CI is 1.645, and the CI is calculated as

CI =  (x₁ - x₂) ± z * SE

So, we have

CI = (-17.1 + 16.0) ± 1.645 * 0.86

This gives

CI = -1.1 ± 1.41

Expand and evaluate

CI = (-2.51, 0.31)

Hence, the confidence interval is -2.51 to 0.31

Answer:

450%<cube root of 92

Step-by-step explanation:

The function f is increasing on the interval (-∞, 5) and on the interval (6, ∞).

To determine the intervals on which the function f is increasing, we need to examine the sign of its derivative f'(x). Since f'(x) is a polynomial, it is continuous everywhere. The sign of f'(x) changes at the zeros of f'(x), which occur at x = 5, x = -8, and x = 6.

To the left of x = -8, f'(x) is positive because all the factors (x - 5)^6, (x + 8)^5, and (x - 6)^4 are positive. From x = -8 to x = 5, f'(x) is negative because (x + 8)^5 is negative while the other two factors remain positive. Finally, to the right of x = 6, f'(x) is positive again since all three factors are positive.

Therefore, the function f is increasing on the interval (-∞, 5) and on the interval (6, ∞) because the derivative f'(x) is positive in those intervals.
