Evaluate the function h(t)= t2 - 8t+12 at t=0. Then plot the point on the graph.

You would need to wait approximately 51.33 years from now to grow your initial investment of $39,000 to $174,000 at an interest rate of 10% per year.

To calculate the number of periods (years) required to grow an initial investment to a desired future value, we can use the formula for compound interest:

FV = PV * \((1 + r)^n\)

Where:

FV is the future value

PV is the present value (initial investment)

r is the interest rate per period

n is the number of periods

In this case:

PV = $39,000

FV = $174,000

r = 10% per year

Let's calculate the number of periods (years):

FV = PV * \((1 + r)^n\)

174,000 = 39,000 * \((1 + 0.10)^n\)

Divide both sides by 39,000:

4.4615 = \((1.10)^n\)

Take the logarithm of both sides to solve for n:

log(4.4615) = n * log(1.10)

n ≈ log(4.4615) / log(1.10)

n ≈ 2.1270 / 0.0414

n ≈ 51.33 (rounded to two decimal places)

If the sample is genuinely random, the mode of the sample may or may not be equal to the mode or mean of the population. The population size must always be equal to the sample size.

A sample's mode is the most common value in the sample. Depending on the variables specified, it might be greater, lower, or equal to the population mode. In general, when the sample size is high enough, the sample mode is assumed to be identical to the population mode. Nevertheless, this is not always the case. The chance of picking any one item in a genuinely random sample is the same throughout the whole population. This means that the mode of the sample may not always be the same as the mode or mean of the population. The sample mode might be greater or lower than the population mode. The population size must always be equal to the sample size. If the population size is 500, the sample size must be 500 as well. Any sample size less than that of the population will not correctly reflect the population.

The perimeter of the rectangle is 3200cm.

The perimeter of a rectangle is the sum of the lengths of all four sides of the rectangle. It is calculated by adding the length and the width of the rectangle and then multiplying the sum by 2.

In this case, the rectangle has a length of 12 meters and a width of 400 centimeters. To find the perimeter in centimeters, we first need to convert the length in meters to centimeters.

As 1 meter is equal to 100 centimeters, we multiply 12 meters by 100 to get 1200 centimeters.

Now we add the width of 400 centimeters to this value and get 1200+400 = 1600.

And finally, we multiply this value by 2 to get the perimeter of the rectangle,

1600*2 = 3200.

The length and width of the plot that will maximize the area is 60 meters by 120 meters. The largest area that can be enclosed is 7200 square meters.

To maximize the area of the rectangular plot, Farmer Ed must use 9000 meters of fencing to enclose three sides of the plot. The fourth side, which borders the river, does not need to be fenced. To find the length and width of the plot that will maximize the area, the 9000 meters of fencing must be divided into two sides of equal length, with the remaining fencing used for the third side. This results in a length of 120 meters and a width of 60 meters, which maximizes the area of the plot. The largest area that can be enclosed is 7200 square meters.

The proportion of cherry tomatoes that are rejected due to being at most 15 mm or at least 30 mm in diameter is approximately 0.0040, or 0.4%.

We need to first determine the z-scores corresponding to these values in order to determine the percentage of cherry tomatoes that are rejected because they are either at most 15 mm or at least 30 mm in diameter. Where x is the diameter, is the mean diameter, and is the standard deviation, we can apply the formula.

The z-score for a 15 mm diameter is z = (15 - 22) / 2.5 = -2.8. The z-score for a 30 mm diameter is z = (30 - 22) / 2.5 = 3.2.

As the tomatoes that go outside the range between these two z-scores are the ones that are rejected, we are interested in learning what percentage of tomatoes do so. The area under the normal curve outside of this range can be calculated using a calculator or a conventional normal distribution table.

Left of z = -2.8 is the area of 0.0033, while right of z = 3.2 is the area of 0.0007. We multiply these two probabilities together to get the total area outside of this range: 0.0033 + 0.0007 = 0.0040.

As a result, 0.4%, or around 0.0040, of cherry tomatoes are rejected because they have a diameter of at least 30 mm and no more than 15 mm.

The option that comes the closest to the correct response is 0.0033. That is not the appropriate answer since it only considers the region to the left of z = -2.8 and excludes the region to the right of z = 3.2.

Mixed methods research tends to be more complex when compared to quantitative and qualitative research respectively. This is because mixed methods research combines both quantitative and qualitative research methods in a single study.

Quantitative research involves the collection and analysis of numerical data, while qualitative research involves the collection and analysis of non-numerical data, such as words, images, and sounds.

Mixed methods research, on the other hand, involves the collection and analysis of both types of data. This requires the researcher to have a deeper understanding of both quantitative and qualitative research methods, as well as the ability to integrate the two types of data in a meaningful way.

Furthermore, mixed methods research often involves the use of multiple data sources, multiple research methods, and multiple levels of analysis. This adds an additional layer of complexity to the research process.

When comparing the means of samples from two normally distributed populations, with independent samples and known population variances, a z-test can be used.

The z-test is a statistical test used to compare means when certain assumptions are met. In this case, the populations from which the samples are drawn are assumed to be normally distributed. The samples being compared should be independent of each other, meaning that the values in one sample are not related to or influenced by the values in the other sample. Additionally, it is assumed that the population variances are known, which is not always the case in practice.

The z-test relies on the calculation of a test statistic called the z-score, which measures the difference between the sample means in terms of standard deviations. The z-score is calculated by subtracting the mean of one sample from the mean of the other sample, and then dividing by the standard deviation of the sampling distribution of the difference in means. The resulting z-score is compared to a critical value from the standard normal distribution to determine the statistical significance of the difference between the means.

If the absolute value of the z-score exceeds the critical value, it indicates that the difference between the sample means is statistically significant, suggesting that the population means are likely to be different. On the other hand, if the z-score is not statistically significant, it suggests that the difference between the sample means may be due to chance, and there is not enough evidence to conclude that the population means are different.

Overall, when comparing the means of samples from normally distributed populations with known variances and independent samples, a z-test provides a way to assess the statistical significance of the difference between the means.

To evaluate (f+g)(-2), we need to substitute -2 into the functions f(x) and g(x), and then add the results.

Given:

f(x) = 3x + 4

g(x) = x - x^2

First, we substitute -2 into f(x):

f(-2) = 3(-2) + 4

= -6 + 4

= -2

Next, we substitute -2 into g(x):

g(-2) = (-2) - (-2)^2

= -2 - 4

= -6

Now, we add the results of f(-2) and g(-2):

(f+g)(-2) = f(-2) + g(-2)

= -2 + (-6)

                      check :  $25 - $18 = $7

$7 is what she needs to finish paying back.  

In total, there are 6 * 6! = 720 different ways for the group of 7 people to sit in the row.

The total number of ways to arrange a group of n people in a row is n!, which is the product of all the integers from 1 to n. However, in this case, we have a constraint that one of the people must sit next to an aisle. To find the number of ways to arrange the group of people given this constraint, we first need to determine the number of ways for the person who needs to sit next to the aisle to be placed.

Since there are 7 seats in the row, and the person must sit next to an aisle, there are 6 different spots where they can sit (either in the first seat, second seat, etc. up to the sixth seat). Once that person is placed, we can use the formula n! to find the number of ways to arrange the remaining people. In this case, there are 6 people remaining, so there are 6! ways to arrange them. To find the total number of ways to arrange the group of 7 people given the constraint, we multiply the number of ways to place the person next to the aisle (6) by the number of ways to arrange the remaining people (6!). So, 6*6! = 720.
