The probability of randomly selecting 4 adult females with pulse rates in a certain range can be determined using the normal distribution, despite the sample size being less than 30.    

In part (a) of the problem, we are interested in finding the probability of randomly selecting 4 adult females with pulse rates in a certain range, assuming that the pulse rates follow a normal distribution with a mean of 73.25. To calculate this probability, we can use the properties of the normal distribution.

Even though the sample size is less than 30, we can still use the normal distribution in this case. This is because we are interested in the distribution of the sample mean, not the distribution of individual pulse rates. The central limit theorem states that when the sample size is sufficiently large, the distribution of the sample means will be approximately normal, regardless of the shape of the original population distribution.

Therefore, option A is the correct explanation. Since we are dealing with the distribution of sample means and not individuals, the distribution will be approximately normal for any sample size. The normal distribution is a useful approximation for many real-world scenarios, even when the sample size is less than 30, as long as certain conditions are met (e.g., the population is not heavily skewed or has extreme outliers).

In conclusion, we can use the normal distribution to calculate the probability of selecting 4 adult females with pulse rates within a certain range, even though the sample size is less than 30, because we are considering the distribution of sample means rather than individual values.

The surface area of a square pyramid is equal to: B. 64 m².

In Mathematics, the surface area of a square pyramid can be calculated by using this mathematical equation:

Surface area of square pyramid = \(a^2+2a\sqrt{(\frac{a}{4})^2 +h^2}\)

where:

For the height, we have:

6² = h² + (4/2)²

36 = h² + 4

h² = 32

h = √32

Height, h = 5.7 m.

By substituting the given side lengths into the formula for the surface area of a square pyramid, we have the following;

Surface area of square pyramid = \(4^2+2(4)\sqrt{(\frac{4}{4})^2 +5.7^2}\)

Surface area of square pyramid = \(16+8\sqrt{(1 +32)}\)

Answer:

y = -6x + 6

Step-by-step explanation:

The general equation of a line is

y = mx + b

where m is the slope and b is the y-intercept

The slope in the first equation is 1/6

Mathematically, when two lines are perpendicular, the product of their slopes is -1

1/6 * m2 = -1

m2 = -6

So we have the equation as;

y-y1 = m(x-x1)

y-23 = -6(x + 3)

y = -6x -18 +23

y = -6x + 6

=========================

When two chords of a circle intersect within the circle, the product of the segments of one chord is equal to the product of the segments of the other chord.

---------------

If two secant segments are drawn to a circle from an exterior point, then the product of the measures of one secant segment and its external secant segment is equal to the product of the measures of the other secant segment and its external secant segment.

---------------

If a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment.

The required value of the t-test statistic is -2 for testing the pair of hypotheses.

To compute the test statistic for this hypothesis test, we need to use the formula for the t-statistic:

t = (x - μ) / (s / √n)

where x is the sample mean, μ is the population mean (in this case, the true mean checkout time that the owner is claiming), s is the sample standard deviation, and n is the sample size.

Plugging in the given values, we get:

t = (11.4 - 12) / (2.4 / √64) = -0.6 / 0.3 = -2

So, the test statistic value is -2. This value can be used to determine the p-value, which can be compared to a significance level to determine whether to reject or fail to reject the null hypothesis.

For the given dataset on crime in 90 counties in North Carolina from 1981 to 1987, a multiple linear regression analysis was conducted to answer the research question.

The selected independent variables were chosen based on logical reasoning. The findings of the regression analysis are summarized in a professional paper.

In conducting the multiple linear regression analysis, several independent variables can be considered based on logical reasoning and prior knowledge. Some possible variables that could be included in the regression model are population size, poverty rate, unemployment rate, education level, and median household income. These variables are often associated with crime rates and can provide insights into the factors influencing crime in the counties of North Carolina.

The analysis involves fitting a regression model to the dataset, assessing the significance and magnitude of the regression coefficients, examining the goodness-of-fit measures, and evaluating the overall significance of the model. The interpretation of the regression coefficients will provide insights into the relationships between the independent variables and the dependent variable (crime rate) and help understand which factors contribute significantly to the variation in crime rates among the counties.

The findings of the regression analysis, including the significant variables, their coefficients, and the overall model fit, will be summarized in a professional paper. The paper will provide a comprehensive analysis of the dataset, discuss the implications of the findings, and draw conclusions based on the results obtained from the multiple linear regression analysis.

In probability theory, the complement of an event represents the probability of the event not occurring. Therefore :

a. The probability of event A not occurring is 0.6.

b. The probability of both events A and B occurring simultaneously is 0.24.

c. The conditional probability of event A given that event B has occurred is 0.167.

d. The conditional probability of event B given that event A has occurred is 0.25.

e. Events A and B are dependent.

a. P(Aˉ) represents the probability of the complement of event A, which is the probability of A not occurring. Since the complement of A is everything that is not A, we can calculate P(Aˉ) as 1 - P(A).

P(Aˉ) = 1 - P(A) = 1 - 0.4 = 0.6

b. P(AB) represents the probability of both events A and B occurring simultaneously. P(AB) = P(A) * P(B) = 0.4 * 0.6 = 0.24

c. P(A|B) represents the conditional probability of event A given that event B has occurred. It can be calculated using the formula:

P(A|B) = P(A∩B) / P(B)

We can rearrange the formula P(A∩B) = P(A|B) * P(B) and substitute the given values to calculate P(A∩B).

P(A∩B) = P(A|B) * P(B) = P(A∪B) - P(B) = 0.7 - 0.6 = 0.1

Then we can use the formula for conditional probability to calculate P(A|B).

P(A|B) = P(A∩B) / P(B) = 0.1 / 0.6 = 1/6 ≈ 0.167

d. P(B|A) represents the conditional probability of event B given that event A has occurred. Similar to part c, we can use the formula:

P(B|A) = P(A∩B) / P(A)

Substituting the calculated values from part c, we get:

P(B|A) = 0.1 / 0.4 = 1/4 = 0.25

e. To determine if events A and B are independent, we need to check if P(A) * P(B) equals P(A∩B). If they are equal, the events are independent. If not, they are dependent.

P(A) * P(B) = 0.4 * 0.6 = 0.24

P(A∩B) = 0.1

Since P(A) * P(B) is not equal to P(A∩B), events A and B are dependent.

Based on the formula given for the model of the average cost of tuition and fees, the average cost of tuition in 2010 was $25,858.

The base year is 2000 and x denotes the number of years after 2000.

The value of x for 2010 is therefore:

= 2010 - 2000

= 10 years

The average cost of tuition in 2010 is therefore:
= 26 (10)² + 814(10) + 15,118

The net income for Griffin's Goat Farm, Inc., was \(\$184,340\).

The operating cash flow (OCF) for Kerber's Tennis Shop, we can use the following formula:

\(OCF = EBIT + Depreciation - Taxes + \triangle Working Capital\)

where EBIT is earnings before interest and taxes.

Calculate EBIT by subtracting interest expense from operating income:

EBIT = Operating Income - Interest Expense

We do not have the information for operating income, but we can use the fact that interest expense was. \(\$165,000\) to calculate EBIT.

EBIT = Interest Expense / (1 - Tax Rate)

= \(\$165,000 / (1 - 0)\)

= \(\$165,000\)

Calculate the change in working capital (Δ Working Capital). We are told that the company reduced its net working capital investment by \(\$69,000\), which means that working capital increased by  \(\$69,000\).

Therefore:

\(\triangle Working Capital = \$69,000\)

Now, we can calculate OCF:

OCF = EBIT + Depreciation - Taxes + Δ Working Capital

=\(\$165,000 + 0 - 0 +\ $69,000\)

=\(\$234,000\)

Therefore, the firm’s 2018 operating cash flow (OCF) was \(\$234,000\) .

To calculate the net income for Griffin's Goat Farm, we can use the following formula:

Net Income = EBIT - Interest Expense - Taxes

where EBIT is earnings before interest and taxes. We can calculate EBIT as:

EBIT = Sales - Costs - Depreciation

= \(\$686,000 - \$332,000 - \$65,000\)

=\(\$289,000\)

Next, we need to calculate taxes. We are given a tax rate of 24%, so:

Taxes = Tax Rate x (EBIT - Depreciation)

= \(0.24 \times (\$289,000 - \$65,000)= \$56,160\)

Now, we can calculate net income:

Net Income = EBIT - Interest Expense - Taxes

= \(\$289,000 - \$48,500 - \$56,160= \$184,340\)

False. When linearizing exponential data using logarithms, the data will become linear and the r²-value of the regression line will likely increase.

The logarithm transformation of the data will help to better fit the data with a linear regression line, since linear regression is used to fit linear data. Therefore, the use of logarithms can actually increase the r²-value of the regression line, not decrease it.

It is important to note that the r²-value does not necessarily indicate the accuracy of the model, but rather how well the model fits the data.
