Answer: 10.5

Step-by-step explanation:

(a) 1. If A, then B: True

2. If B, then A: False

3. A if and only B: False

(a) If a polygon PQRS is a rectangle, it is also a parallelogram, as all rectangles are parallelograms.

Therefore, the statement "If A, then B" is true. However, if a polygon is a parallelogram, it does not necessarily mean it is a rectangle, as parallelograms can have other shapes. Hence, the statement "If B, then A" is false. The statement "A if and only B" is also false since a rectangle is a specific type of parallelogram, but not all parallelograms are rectangles. Therefore, the correct answer is: If A, then B is true, If B, then A is false, and A if and only B is false.

(b) 1. If A, then B: True

2. If B, then A: False

3. A if and only B: False

(b) If Joe is a grandfather, it implies that Joe is male, as being a grandfather is a role that is typically associated with males. Therefore, the statement "If A, then B" is true. However, if Joe is male, it does not necessarily mean he is a grandfather, as being male does not automatically make someone a grandfather. Hence, the statement "If B, then A" is false. The statement "A if and only B" is also false since being a grandfather is not the only condition for Joe to be male. Therefore, the correct answer is: If A, then B is true, If B, then A is false, and A if and only B is false.

(c) 1. If A, then B: True

2. If B, then A: True

3. A if and only B: True

(c) If x is greater than 0 (x > 0), it implies that x squared is also greater than 0 (x^2 > 0). Therefore, the statement "If A, then B" is true. Similarly, if x squared is greater than 0 (x^2 > 0), it implies that x is also greater than 0 (x > 0). Hence, the statement "If B, then A" is also true. Since both statements hold true in both directions, the statement "A if and only B" is true. Therefore, the correct answer is: If A, then B is true, If B, then A is true, and A if and only B is true.

(d) 1. If A, then B: False

2. If B, then A: False

3. A if and only B: False

(d) If x is less than 0 (x < 0), it does not imply that x cubed is less than 0 (x^3 < 0). Therefore, the statement "If A, then B" is false. Similarly, if x cubed is less than 0 (x^3 < 0), it does not imply that x is less than 0 (x < 0). Hence, the statement "If B, then A" is false. Since neither statement holds true in either direction, the statement "A if and only B" is also false. Therefore, the correct answer is: If A, then B is false, If B, then A is false, and A if and only B is false.

The question is an illustration of composite functions.

The given parameters are:

(a) Functions c(n) and n(h)

Let the number of system be n, and h be the number of hours

So, the cost function (c(n)) is:

\(\mathbf{c(n) = Fixed + Additional \times n}\)

This gives

\(\mathbf{c(n) = 5000 + 250 \times n}\)

\(\mathbf{c(n) = 5000 + 250n}\)

The function for number of systems is:

\(\mathbf{n(h) = 5 \times h}\)

\(\mathbf{n(h) = 5h}\)

(b) Function c(n(h))

In (a), we have:

\(\mathbf{c(n) = 5000 + 250n}\)

\(\mathbf{n(h) = 5h}\)

Substitute n(h) for n in \(\mathbf{c(n) = 5000 + 250n}\)

\(\mathbf{c(n(h)) = 5000 + 250n(h)}\)

Substitute \(\mathbf{n(h) = 5h}\)

\(\mathbf{c(n(h)) = 5000 + 250 \times 5h}\)

\(\mathbf{c(n(h)) = 5000 + 1250h}\)

(c) Find c(n(100))

c(n(100)) means that h = 100.

So, we have:

\(\mathbf{c(n(100)) = 5000 + 1250 \times 100}\)

\(\mathbf{c(n(100)) = 5000 + 125000}\)

\(\mathbf{c(n(100)) = 130000}\)

(d) Interpret (c)

In (c), we have: \(\mathbf{c(n(100)) = 130000}\)

It means that:

The size of a sample designed for dual-purpose testing should be determined based on several factors, including the specific objectives of the testing, the desired level of confidence, the acceptable margin of error, and the variability of the population being tested.

Dual-purpose testing typically involves testing for multiple purposes or criteria simultaneously, such as both quality control and compliance assessment.

In such cases, it is important to consider the requirements and constraints of each purpose and determine an appropriate sample size that satisfies both objectives.

To determine the sample size, statistical techniques can be used, such as power analysis or sample size calculation formulas.

These methods take into account the significance level, desired power, effect size, and variability of the variables under consideration. The specific formulas or approaches used may vary depending on the nature of the data and the statistical test being performed.

It is essential to strike a balance between the sample size and the resources available for testing.

A larger sample size generally provides more precise results but may require more time, effort, and resources. Conversely, a smaller sample size may be more practical but could result in less precise estimates.

Ultimately, the appropriate sample size for dual-purpose testing should be determined through careful consideration of the specific objectives, statistical requirements, available resources, and the trade-off between precision and practicality.

In various settings, such as work or school, measures of location, measures of variability, and measures of association can provide valuable insights and aid in interpreting data.

Let's consider an example from a work setting where employee performance data is collected

Measures of location, such as the mean or median, can illustrate an important aspect of employee performance. By calculating the mean performance score, we can identify the average level of performance across the organization. This measure helps us understand the central tendency of the data and provides a benchmark to assess individual employee performance against the average. If the mean performance score is low, it indicates the need for improvement in overall performance.

Measures of variability, such as the standard deviation, can indicate the spread or dispersion of performance scores. A high standard deviation suggests a wide range of performance levels among employees, indicating a lack of consistency. This insight prompts organizations to investigate the underlying factors contributing to the variability and identify areas for improvement in training, resources, or performance management processes.

Furthermore, measures of association, such as correlation coefficients, can help identify relationships between variables. For example, we can explore the correlation between employee performance scores and factors like years of experience, education level, or training hours. Understanding these associations can guide decision-making processes, such as designing targeted training programs for employees who exhibit a lower correlation between training hours and performance.

By applying these measures and interpreting the data, organizations can gain valuable insights into employee performance. This understanding can lead to improved decision-making, such as identifying areas for performance improvement, optimizing resource allocation, and implementing targeted interventions to enhance overall productivity and success within the work setting.

To use the normal approximation for a test of two proportions, n1 p1, n1 (1 - p1), n2 p2, and n2 (1 - p2) must all be greater than or equal to 5.

This is because the normal distribution assumes that the sample size is large enough to approximate the binomial distribution, and the rule of thumb is that each cell (n1 p1, n1 (1 - p1), n2 p2, and n2 (1 - p2)) should have at least 5 expected counts. If any of these cells have fewer than 5 expected counts, then the normal approximation is not reliable and a more appropriate test should be used. It is important to note that this is just a rule of thumb, and other factors such as the size of the effect and the desired level of significance should also be considered when deciding on a statistical test.

(a) If we believe that the algorithm takes a time roughly proportional to n^2, then we can use the following proportion:

1 second is to 1000^2 as x seconds is to 10000^2

1 : 1000000 :: x : 100000000

Cross-multiplying, we get:

x = (1 * 100000000) / 1000000

x = 100 seconds

So, we would expect it to take 100 seconds to sort 10,000 items using this algorithm.

(b) If we believe that the algorithm takes a time roughly proportional to n log n, then we can use the following equation:

T(n) = k * n log n

where T(n) is the time it takes to sort n items, and k is a constant of proportionality that we don't know.

We can solve for k using the fact that the algorithm takes 1 second to sort 1000 items:

1 = k * 1000 log 1000

1 = k * 3000

k = 1/3000

Now, we can use this value of k to find the time it takes to sort 10,000 items:

T(10000) = (1/3000) * 10000 log 10000

T(10000) ≈ 42 seconds

So, we would expect it to take about 42 seconds to sort 10,000 items using this algorithm.

(a) Using these values, we can plot the points (-2, -5), (-1, -3), (0, -1), (1, 1), (2, 3), and (3, 5) on a coordinate plane. (b) We start with the graph of y = log(x) and translate it 2 units to the right to obtain the graph of f(x) = log(x - 2).

(a) To graph the function f(x) = 2x - 1, we can generate a table of values by choosing different values for x and calculating the corresponding y-values.

Let's choose a range of x-values and calculate the corresponding y-values:

x                   f(x)

-2                 -5

-1                  -3

0                   -1

1                     1

2                    3

3                    5

Connecting these points with a straight line will give us the graph of the function f(x) = 2x - 1.

(b) To graph the function f(x) = log(x - 2), we first need to identify the base function, which is the logarithmic function with base 10.

The base function y = log(x) is a vertical asymptote at x = 0, and its graph passes through the point (1, 0).

To graph the function f(x) = log(x - 2), we can describe the transformation compared to the base function. The transformation is a translation to the right by 2 units, shifting the vertical asymptote to x = 2. The graph still passes through the point (1, 0), but it is shifted to the right.

Answer:

1) Pr(all three) = 0.064

2) Pr(none) = 0.216

3) Independent event

Step-by-step explanation:

Let Probability of homes constructed in the Quail Creek area with a security system = Pr (security)

Where Pr = probability

This is a binomial distribution problem. There ate only two outcomes in this distribution: a success and a failure

Where p = success, q = failure

For n trials,

Pr(X = x) = n!/[(n-x)!x!] × p^x × q^(n-x)

Pr (security) = 40% = 0.4

p = 0.4

q = 1-p = 1-0.4 = 0.6

Numbers selected at random = n = 3

See attachment for more details on the workings.

1) Probability all three of the selected homes have a security system = Pr(all three)

Pr(all three) = 1× (0.4)³ (0.6)^0 = 0.4³

= 0.4×0.4×0.4

Pr(all three) = 0.064

2) Probability none of the three selected homes have a security system

= Pr(none)

Pr(none) = 1 × (0.4)^0 × (0.6)³

= 0.6³ = 0.6×0.6×0.6

Pr(none) = 0.216

3) The events were assumed to be independent as the selection of one house doesn't affect the outcome of the selection of another.
