The probability that exactly 17 households own a DVD player is 0.0124.

Given:

The probability that a house hold in centercity owns a DVD player is = 53%.

So, p = 0.53

The probability that a house hold in centercity does not own a DVD player is = 100% - 53% = 47%

So, q = 0.47

The sample size is 22 households in the city.

So, n = 22

We have to calculate the probability that exactly 17 households own a DVD player.

So, r = 17

The formula to be used in binomial experiment is:

P (r) = \(\frac{n!}{r! (n -r)!}\) × \(p^{r}\) ×\(q^{n-r}\)

The probability that exactly 17 households own a DVD player will be,

= \(\frac{22!}{17! (22 - 17)!}\) × \(0.53^{17}\) ×\(0.43^{22-17}\)

= \(\frac{22!}{17! (5)!}\)× \(0.53^{17}\) ×\(0.43^{5}\)

= 0.0124

Therefore, the probability that exactly 17 households own a DVD player is 0.0124.

1. Probability of observing the microstate HHTHHH is (a) 5.47e-02.

2. Number of microstates consistent with the macrostate 6 Heads and 1 Tails is (d) 7.

Let's discuss it further below.

(a) To find the probability of observing the microstate HHTHHH, you need to calculate the probability of getting each result in the sequence. Since it is a fair coin, the probability of getting heads (H) is 1/2 and tails (T) is also 1/2.

Step 1: Calculate the probability for HHTHHH.
Probability = (1/2)⁶ = (1/64) = 0.015625 = 1.56e-02

So, the answer for the probability of observing the microstate HHTHHH is (a) 5.47e-02.

(b) To find the number of microstates consistent with the macrostate 6 Heads and 1 Tails, you need to find the number of ways to arrange 6 H's and 1 T in a sequence of 7 coin tosses.

Step 2: Use combinations formula: C(n, k) = n! / (k!(n-k)!)
In this case, n=7 (total coin tosses) and k=6 (number of heads).

C(7, 6) = 7! / (6!(7-6)!) = 7! / (6!1!) = 7

So, the answer for the number of microstates consistent with the macrostate 6 Heads and 1 Tails is (d) 7.

Answer:

1. True

2. False.

3. True.

Step-by-step explanation:

1. The total area within any continuous probability distribution is equal to 1.00: it is true because the maximum probability (value) is one (1), therefore, the total (maximum) area is also one (1).

Hence, for continuous probability distribution: probability = area.

2. For any continuous probability distribution, the probability, P(x), of any value of the random variable, X, can be computed: False because it has an infinite number of possible values, which can not be counted or uncountable.

Hence, it cannot be computed.

3. For any discrete probability distribution, the probability, P(x), of any value of the random variable, X, can be computed: True because it has a finite number of possible values, which are countable or can be counted.

Hence, it can be computed.

The statement 'In order to calculate MACRS depreciation, the business needs to know the asset's original cost, the depreciation period, and which depreciation method (i.e. 200% declining balance) is used.' is false. because, the asset was used for both personal and business purposes, the business must calculate the percentage of business use in order to determine the correct depreciation deduction.

While the asset's original cost, depreciation period, and depreciation method are all necessary inputs for calculating MACRS depreciation, there are other pieces of information that are also required.

For example, the business must determine the applicable MACRS recovery period and the property's placed-in-service date, as well as any applicable conventions for calculating the depreciation.

Additionally, if the asset was used for both personal and business purposes, the business must calculate the percentage of business use in order to determine the correct depreciation deduction.

To find the P(Z>0.93) using Appendix C-2, we first need to find the row containing 0.9 in the far left column. Next, we find the column containing 0.03 in the top row. The intersection of the row and column is 1.546. Therefore, the probability of Z being greater than 0.93 is 1 - 0.8289 = 0.1711 (rounded to four decimal places).

The values in Appendix C-2 represent the area to the left of a standard normal distribution. Since the total area under the curve is equal to 1, we can find the area to the right of a certain value by subtracting the area to the left from 1.

In this case, we want to find the area to the right of 0.93, which is equivalent to finding the area to the left of -0.93 (since the standard normal distribution is symmetric). By finding the corresponding value in Appendix C-2 and subtracting from 1, we get the probability of Z being greater than 0.93.

The cost of a pack of cigarettes was $0.86 in 1980 and in 2000, the average cost was $4.95 per pack.To find: The average rate of change of the cost of a pack of cigarettes and create a linear equation using the year 1980 as your starting year.

Average Rate of Change:Average rate of change of the cost of a pack of cigarettes is given by the formula:

Average rate of change = (Change in cost) / (Change in time)Change in cost

= ($4.95 - $0.86)

= $4.09

Change in time = (2000 - 1980)

= 20 years

Putting these values in the formula, we get

,Average rate of change = $4.09 / 20

Average rate of change = $0.2045 per year Linear equation:

We need to find a linear equation using the year 1980 as the starting year. To find this, we will use the point-slope form of a linear equation.

The average rate of change of the cost of a pack of cigarettes can be found by subtracting the initial cost from the final cost and dividing it by the number of years that have passed. The average rate of change of the cost of a pack of cigarettes is approximately $0.2045 per year.

To calculate the average rate of change, we can use the formula:

Average rate of change = (final cost - initial cost) / number of years

In this case, the initial cost in 1980 was $0.86, and the final cost in 2000 was $4.95. The number of years that have passed is 2000 - 1980 = 20.

Plugging these values into the formula, we have:

Average rate of change = ($4.95 - $0.86) / 20

Calculating the numerator, we get:

Average rate of change = $4.09 / 20

Dividing, we find that the average rate of change is approximately $0.2045 per year.

To create a linear equation using the year 1980 as the starting point, we can use the point-slope form of a linear equation:

y - y1 = m(x - x1)

Where y represents the cost of a pack of cigarettes, x represents the number of years since 1980, m represents the average rate of change, and (x1, y1) represents the starting point.

Using the values we have, we can substitute x1 = 0 (since 1980 is the starting point) and y1 = 0.86 (the initial cost) into the equation:

y - 0.86 = 0.2045(x - 0)

Simplifying, we get:

y - 0.86 = 0.2045x

Rearranging, we have:

y = 0.2045x + 0.86

Therefore, the linear equation representing the average rate of change of the cost of a pack of cigarettes starting from 1980 is:

y = 0.2045x + 0.86

In this equation, x represents the number of years since 1980, and y represents the cost of a pack of cigarettes in dollars.

In conclusion, the average rate of change of the cost of a pack of cigarettes is approximately $0.2045 per year. The linear equation representing this average rate of change, starting from 1980, is y = 0.2045x + 0.86. In this equation, x represents the number of years since 1980, and y represents the cost of a pack of cigarettes in dollars.
