The formula for the volume of a cone is:

V = (1/3)πr²h

where r is the radius of the base, h is the height of the cone, and π is pi.

In this case, the slant height is given as 17 cm, which we can use with the radius to find the height of the cone using the Pythagorean theorem:

h² = s² - r²

h² = 17² - 8²

h² = 225

h = 15

Now that we have the height, we can plug in the values for r and h into the formula for the volume:

V = (1/3)π(8²)(15)

V = (1/3)π(64)(15)

V = (1/3)(960π)

V = 320π

Therefore, the volume of the cone is 320π cubic cm. Answer: 320π.

To find the required sample size for a margin of error less than 3%, we can rearrange the formula for the margin of error:

\(n = (Z^2 * p * (1 - p)) / (E^2)\)

Here, Z represents the critical value, p is the estimated proportion (0.51), and E is the desired margin of error (0.03)

To determine the margin of error for the 95% confidence interval, we need to use the formula:

Margin of Error = Critical value * Standard error

The critical value for a 95% confidence level can be obtained from the standard normal distribution table, which corresponds to 1.96. The standard error can be calculated using the following formula:

Standard error = \(\sqrt{(p * (1 - p) / n)}\)

Given that the proportion of North Carolina residents planning to set off fireworks is estimated to be 51% (0.51) based on the survey, we can substitute the values into the formula. However, the sample size (n) is not provided in the question, so we need to determine it in the next part.

To find the required sample size for a margin of error less than 3%, we can rearrange the formula for the margin of error:

Profitability index is 1.387. Thus, the correct option is (c) 1.387.

The formula for calculating the profitability index is:

P.I = PV of Future Cash Flows / Initial Investment

Where,

P.I is the profitability index

PV is the present value of future cash flows

The initial investment in the project is $30 million. The cash flow at the end of the first year is $2.85 million.

The present value of cash flows can be calculated using the formula:

PV = CF / (1 + r)ⁿ

Where,

PV is the present value of cash flows

CF is the cash flow in the given period

r is the discount rate

n is the number of periods

For the first-year cash flow, n = 1, CF = $2.85 million, and r = 11%.

Substituting the values, we get:

PV = 2.85 / (1 + 0.11)¹ = $2.56 million

To calculate the present value of all future cash flows, we can use the formula:

PV = CF / (r - g)

Where,

PV is the present value of cash flows

CF is the cash flow in the given period

r is the discount rate

g is the constant growth rate

For the subsequent years, CF = $2.85 million, r = 11%, and g = 3.85%.

Substituting the values, we get:

PV = 2.85 / (0.11 - 0.0385) = $39.90 million

The total present value of cash flows is the sum of the present value of the first-year cash flow and the present value of all future cash flows.

PV of future cash flows = $39.90 million + $2.56 million = $42.46 million

Profitability index (P.I) = PV of future cash flows / Initial investment

= 42.46 / 30

= 1.387

Therefore, the correct option is (c) 1.387.

The statement "If x = -10, then x² = 100" is false. When we square -10, we get 100, so the correct statement would be "If x = -10, then x² = 100."

The statement that is NOT true is:

If x = -10, then x² = 100.

The other three statements are all true:

If x² = 100, then x = 10.This is true because the square root of 100 is ±10, and when we take the square root, we consider the positive square root, which is 10.

If x = 10, then x² = 100. This is also true because when we square 10, we get 100.The statement x² = 100 if and only if x = 10 or x = -10 is true.

This statement is based on the fact that the square root of 100 is ±10, so when we square either 10 or -10, we get 100.

The most likely conclusion supported by the data is that there is no significant difference between the two categorical variables.

A conditional relative frequency table compares the relative frequencies of two categorical variables based on a set of data. In this case, the relative frequencies are given as 0.48 and 0.52.

When the relative frequencies are close in value (0.48 and 0.52), it suggests that the two categorical variables are similar and do not have a significant difference. A small difference in relative frequencies indicates that the variables are likely independent or have a weak association.

If there were a substantial difference in the relative frequencies (e.g., 0.20 and 0.80), it would suggest a strong association between the variables. However, since the relative frequencies in this case are close (0.48 and 0.52), it is more likely that there is no significant difference between the two variables.

It's important to note that further analysis and statistical tests may be required to make a definitive conclusion based on the given data.

Temperature of refrigerators - Cannot determine. Horsepower of race car engines - Ratio. Marital status of school board members - Nominal. Ratings of television programs - Ordinal. Ages of children enrolled in a daycare - Interval

The level of measurement for the temperature of refrigerators cannot be determined based on the given information. The temperature could potentially be measured on a nominal scale if the refrigerators were categorized into different temperature ranges. However, without further context, it is not possible to determine the specific level of measurement.

The horsepower of race car engines can be measured on a ratio scale. Ratio scales have a meaningful zero point and allow for meaningful comparisons of values, such as determining that one engine has twice the horsepower of another.

The marital status of school board members can be measured on a nominal scale. Nominal scales are used for categorical data without any inherent order or ranking. Marital status categories, such as "married," "single," "divorced," etc., can be assigned to school board members.

The ratings of television programs, such as "poor," "fair," "good," and "excellent," can be measured on an ordinal scale. Ordinal scales represent data with ordered categories or ranks, but the differences between categories may not be equal or measurable.

The ages of children enrolled in a daycare can be measured on an interval scale. Interval scales have equal intervals between values, allowing for meaningful differences and comparisons. Age, measured in years or months, can be represented on an interval scale.

The estimated time for the 100th repetition of this job is approximately 111.11 minutes, assuming a learning curve of 90 percent.

To estimate the time for the 100th repetition of the job, we can use the concept of a learning curve. The learning curve assumes that as the number of repetitions increases, the time required decreases at a constant percentage rate. In this case, the learning curve is 90 percent.

To estimate the time for the 100th repetition, we can use the formula:

Estimated time for the 100th repetition = Time for the 50th repetition / (Learning curve)\(^log2\)(100/50)

Plugging in the given values:

Estimated time for the 100th repetition = 100 minutes / (0.90)\(^log2(100/50)\)

Simplifying the expression:

Estimated time for the 100th repetition ≈ 100 minutes / \((0.90)^1\)

Estimated time for the 100th repetition ≈ 100 minutes / 0.90

Estimated time for the 100th repetition ≈ 111.11 minutes

Therefore, the estimated time for the 100th repetition of this job is approximately 111.11 minutes.

Which of the following information about the graph of the relationship is given?

a)Slope and x-intercept

b) Slope and y-intercept

c)X-intercept and y-intercept

d) Y-intercept and a point that is not an intercept

e)Two points that are not intercepts

f)Slope and a point that is not an intercept

Answer:

y = -7x + 2

Step-by-step explanation:

Since we do not have the y-intercept (or, when the x is 0) We will use the Slope Form Formula (y - y1 = m(x - x1)) to find the Slope Intercept Form Formula (y = mx + b)

Point: (-7,51)

Slope: -7

y - y1 = m(x - x1)

y - 51 = -7(x - (-7))

y - 51 = -7(x + 7)

y - 51 = -7x - 49

y = -7x - 49 + 51

y = -7x + 2

You would need a sample size of 53 to estimate the population mean with an error of less than 5 and a 99% confidence level, given a population standard deviation of 13.6.

To estimate the population mean with an error of less than 5 and 99% confidence, you need to determine the required sample size using the given population standard deviation (σ = 13.6) and the desired margin of error (E = 5).

Step 1: Identify the confidence level (99%)
The confidence level indicates the probability that the true population mean lies within the margin of error. A 99% confidence level corresponds to a z-score (z) of 2.576, found in standard z-score tables or through software.

Step 2: Calculate the required sample size
The formula for determining the required sample size (n) when estimating the population mean with a specific margin of error and confidence level is:

n = (z^2 × σ^2) / E^2

Plugging in the values we have:

n = (2.576^2 × 13.6^2) / 5^2
n ≈ (6.635776 × 184.96) / 25
n ≈ 1304.756736 / 25
n ≈ 52.19

Step 3: Round up the result
Since you cannot have a fraction of a sample, round up the result to the nearest whole number. In this case, the required sample size is 53.

In conclusion, you would need a sample size of 53 to estimate the population mean with an error of less than 5 and a 99% confidence level, given a population standard deviation of 13.6.

Step-by-step explanation:

The probability of x falling between 33.53 and 70.97 is approximately 0.9342.

To find the probability of a normally distributed variable falling between two values, we need to standardize the values and then use a standard normal distribution table or calculator.

First, we standardize the values of 33.53 and 70.97 using the formula:

z = (x - μ) / σ

where z is the standardized value, x is the value we want to standardize, μ is the mean, and σ is the standard deviation.

For 33.53:

z = (33.53 - 50) / 9 = -1.8389

For 70.97:

z = (70.97 - 50) / 9 = 2.2178

Next, we look up the area under the standard normal distribution curve between these two standardized values using a table or calculator. Using a standard normal distribution table, we find that:

P(-1.8389 ≤ Z ≤ 2.2178) = 0.9671 - 0.0329 = 0.9342
