The values of n for (a) and (b) are 151 and 152, respectively.

Given statement

Let n be the number of people in the sample.

A researcher wishes to estimate the percentage of adults who own a tablet computer.

He uses a previous estimate of 22%.

We have to find the value of n in the two cases.

Case (a)

When a previous estimate of 22% is used, the margin of error should be 4.5%.

Thus, \(ME = z_{\alpha /2}\sqrt{\frac{p\left( 1-p \right)}{n}}\).

We know that

p = 0.22,

ME = 4.5%, and the value of Zα/2 for a 95% confidence interval is 1.96.

The formula becomes;

\begin{aligned}

4.5&=1.96\sqrt {\frac{0.22 \left( 1-0.22 \right)}{n}}

\\ 0.045^{2}&=1.96^{2}\frac{0.22\left( 0.78 \right)}{n}

\\ \frac{n\times 0.045^{2}}{1.96^{2}\times 0.22\times 0.78}&=1

\\ n&=\frac{0.045^{2}\times 100}{1.96^{2}\times 0.22\times 0.78}

\\ &\approx 150.28

\\ \end{aligned}

Thus the minimum sample size required is n = 150 (rounded up to the nearest integer).

Therefore, n = 151

Case (b)

When no prior estimate is used, the margin of error should be 3%.

Thus, \(ME=z_{\alpha /2}\sqrt{\frac{p\left( 1-p \right)}{n}}\).

We know that ME = 3%, and the value of Zα/2 for a 95% confidence interval is 1.96.

The formula becomes;

\begin{aligned}

3&=1.96\sqrt{\frac{p\left( 1-p \right)}{n}}

\\ 0.03^{2}&=1.96^{2}\frac{0.25}{n}

\\ \frac{n\times 0.03^{2}}{1.96^{2}\times 0.25}&=1

\\ n&=\frac{0.03^{2}\times 100}{1.96^{2}\times 0.25}

\\ &\approx 151.52

\\ \end{aligned}

Thus the minimum sample size required is n = 151 (rounded up to the nearest integer).

Therefore, n = 152.

Hence, the values of n for (a) and (b) are 151 and 152, respectively.

Answer:

\(x = -8\)

Step-by-step explanation:

\(\begin{cases}2y = 2x + 12\\2-y = 4\end{cases}\)

It would be easier to start with the second equation.

\(2 - y = 4 \text{ // Add y and subtract 4}\\\to 2 - y - 4 = 4 - y - 4\\\to -2 = y\)

From here, we can substitute \(y = -2\) into the first equation, to solve for \(x\).

\(2(-2) = 2x + 12\\\to -4 = 2x + 12 \text{ // Subtract 12 on both sides}\\\to -4 - 12 = 2x + 12 - 12\\\to -16 = 2x \text{ // Divide by 2}\\\to -\frac{16}2 = \frac{2x}2\\\to -8 = x\)

We know that the production of the years 1987 until 2017 is represented by the equation:

where x is the number of years that passed since 1987. (This means that x=0 gives the production of the year 1987, x=1 gives the production of year 1988 and so on.).

We would like to know tha change in the production of the period from 1992 to 2017.

To know the production in the year 1992 we have to plug the value x=5 in the equation of the production. Then:

To know the production in the year 2017 we have tu plug the value x=30 in the equation, then:

The equation of the rational function with the given properties is:

f(x) = 7 / (x + 1)

To find the equation of a rational function with the given properties, we can start by considering the form of a generic rational function:

f(x) = (ax + b) / (cx + d)

We are given the following information:

Vertical asymptotes at x = -4 and x = -1:

Vertical asymptotes occur when the denominator of the rational function is equal to zero.

In this case, we have (cx + d) = 0 when x = -4 and x = -1. This gives us the equations:

-4c + d = 0 --- (1)

-1c + d = 0 --- (2)

x-intercepts at (1, 0) and (5, 0):

x-intercepts occur when the numerator of the rational function is equal to zero. In this case, we have (ax + b) = 0 when x = 1 and x = 5.

This gives us the equations:

a(1) + b = 0 --- (3)

a(5) + b = 0 --- (4)

y-intercept at (0, 7):

The y-intercept occurs when x = 0.

This gives us the equation:

f(0) = (a(0) + b) / (c(0) + d) = 7

b / d = 7 --- (5)

We now have a system of five equations (1), (2), (3), (4), and (5) with five unknowns (a, b, c, d).

We can solve this system of equations to find the values of a, b, c, and d, which will allow us to determine the equation of the rational function.

By solving the system of equations, we find:

a = 0

b = 7

c = 1

d = 1

Substituting these values back into the generic rational function form, we obtain the equation of the rational function:

f(x) = (7) / (x + 1)

Therefore, the equation of the rational function with the given properties is: f(x) = 7 / (x + 1)

The Algorithm for a time complexity of O(n) is given at the end.

The algorithm with a time complexity of O(n) to solve the problem:

1. Initialize two variables: "min_price" to store the minimum price encountered so far and "max_profit" to store the maximum profit found so far. Set both variables to infinity or a very large number.

2. Iterate through the given prices from left to right, for each day i:

  - Update min_price as the minimum between min_price and prices[i].

  - Calculate the potential profit as prices[i] - min_price.

  - Update max_profit as the maximum between max_profit and the potential profit.

3. After the iteration, max_profit will contain the maximum profit that can be obtained by buying on one day and selling on a later day.

4. In this case, return a suitable message indicating that there is no profitable opportunity.

5. If max_profit is positive, it represents the maximum profit that can be obtained. To find the specific days i and j, iterate through the prices again and find the day i where the profit is equal to max_profit. Then, continue iterating from day i+1 to find the day j where the price achieves the maximum profit (prices[j] - prices[i]). Return the pair of days (i, j).

The Python code implementing the algorithm:

def find_optimal_days(prices):

   n = len(prices)

   min_price = float('inf')

   max_profit = 0

   buy_day = 0

   sell_day = 0

   for i in range(n):

       min_price = min(min_price, prices[i])

       potential_profit = prices[i] - min_price

       max_profit = max(max_profit, potential_profit)

       if potential_profit == max_profit:

           sell_day = i

   if max_profit <= 0:

       return "No profitable opportunity."

   for i in range(sell_day):

       if prices[sell_day] - prices[i] == max_profit:

           buy_day = i

           break

   return buy_day, sell_day

# Example usage:

prices = [7, 1, 5, 3, 6, 4]

result = find_optimal_days(prices)

This algorithm has a time complexity of O(n), where n is the number of days (length of the prices list). It iterates through the prices list twice, but the overall complexity is linear.

The complex number -2√3 + 2i in trigonometric form r(cosθ + isinθ), with θ in the interval

[0°, 360°) is:\($$-2\sqrt{3} + 2i = 4\left(\cos150^{\circ} + i\sin150^{\circ}\right)$$\)

To convert the complex number -2√3 + 2i to the trigonometric form r(cosθ + isinθ),

we need to find r, the modulus of the complex number, and θ, the argument of the complex number.

Step 1: Find the modulus r of the complex number.

Modulus of the complex number is given by:

|z| = √(a² + b²)

where a and b are the real and imaginary parts of the complex number z.| -2√3 + 2i |

= √((-2√3)² + 2²)

= √(12 + 4)

= √16 = 4

So, r = 4

Step 2: Find the argument θ of the complex number.

Argument θ of a complex number is given by:θ = tan⁻¹(b/a) if a > 0

θ = tan⁻¹(b/a) + π if a < 0 and b ≥ 0

θ = tan⁻¹(b/a) - π if a < 0 and b < 0

θ = π/2 if a = 0 and b > 0

θ = -π/2

if a = 0 and b < 0θ is undefined if a = 0 and b = 0

Here, a = -2√3 and

b = 2θ = tan⁻¹(2/-2√3) + π [Since a < 0 and b > 0]

We can simplify this as follows:θ = tan⁻¹(-1/√3) + πθ ≈ -30° + 180° = 150°

Therefore, the complex number -2√3 + 2i in trigonometric form r(cosθ + isinθ), with θ in the interval [0°, 360°) is:\($$-2\sqrt{3} + 2i = 4\left(\cos150^{\circ} + i\sin150^{\circ}\right)$$\)

American jurists (fill in the names) defined law as predictions of how a court will decide specific legal questions, based on a functional perspective.

American jurists Oliver Wendell Holmes Jr. and Benjamin Cardozo are known for their functionalist approach to defining law. They viewed law not merely as a set of abstract principles or rules, but as a prediction of how courts will decide specific legal questions in practice. According to their perspective, the law should be seen as a dynamic and evolving system that adapts to societal changes and reflects the judgments and decisions of the judiciary. By emphasizing the functional aspect of law, Holmes and Cardozo recognized the importance of considering how legal principles are actually applied and interpreted in real-world scenarios. Their approach acknowledges that the interpretation and application of law by judges can vary and evolve over time, depending on factors such as legal precedent, social context, and the specific facts of the cases before them.
