A landscape architect wishes to enclose a rectangular garden on one side by a brick wall costing $30 per foot and on the other three sides by a metal fence costing $10 per foot. If the area of the garden is 450 ft2, find the dimensions of the garden minimizing the cost.
Answers
The dimensions that minimize the cost are x ≈ 13.42 ft and y ≈ 33.58 ft.
We are given that;
Brick wall costing= $30
Area= 450ft^2
Now,
To find the critical points, we take the derivative of C and set it equal to zero:
C’ = 50 - 9000/x2 C’ = 0 50 - 9000/x2 = 0 9000/x2 = 50 x2 = 9000/50 x2 = 180 x = ±√180 x ≈ ±13.42
Since x must be positive, we only consider x ≈ 13.42 as a critical point. To check if this is a minimum or maximum, we can use the first derivative test or the second derivative test. Using the second derivative test, we find:
C’’ = 18000/x3
Since x ≈ 13.42 is positive, C’’ > 0 at this point, which means C has a local minimum at x ≈ 13.42.
To find the absolute minimum, we also need to evaluate C at the endpoints of its domain:
C(0) = undefined C(450) = 50(450) + 20(1) = 22520
So, C has an absolute minimum at x ≈ 13.42 with a value of:
C(13.42) ≈ 50(13.42) + 20(33.58) ≈ $1,337
To find the dimensions of the garden that minimize the cost, we use y = 450/x and plug in x ≈ 13.42:
y ≈ 450/13.42 y ≈ 33.58
Therefore, by area the answer will be x ≈ 13.42 ft and y ≈ 33.58 ft.

Write a function in R. that generates a sample of size n from a continuous distribution with a given cumulative distribution function (cdf) Fx (x; 0) where 0 = (μ, o, k) or 0 = (w, k) is a vector of parameters with k > 0, σ > 0,µ € R and 0 < w < 1. Use this function to generate a sample of size n = 100 with given parameter values. Draw a histogram for the generated data. Write a function that finds the maximum likelihood estimates of the distribution parameters for the generated data ₁,...,100. Provide estimates of (u, o, k) or (w, k) in your report.
Answers
This will give you the MLE estimates for the distribution parameters based on the generated sample. The estimated parameters are stored in weibull_params, while estimated parameters for the Pareto distribution are stored in pareto_params.
Here's an example of a function in R that generates a sample of size n from a continuous distribution with a given cumulative distribution function (cdf):
# Function to generate a sample from a given cumulative distribution function (cdf)
generate_sample <- function(n, parameters) {
u <- parameters$u
o <- parameters$o
k <- parameters$k
w <- parameters$w
# Generate random numbers from a uniform distribution
u_samples <- runif(n)
if (!is.null(u) && !is.null(o) && !is.null(k)) {
# Generate sample using the parameters (μ, σ, k)
x <- qweibull(u_samples, shape = k, scale = o) + u
# Generate sample using the parameters (w, k)
x <- qpareto(u_samples, shape = k, scale = 1/w)
} else {
stop("Invalid parameter values.")
}
# Generate a sample of size n = 100 with the given parameter values
parameters <- list(u = 1, o = 2, k = 3) # Example parameter values (μ, σ, k)
sample <- generate_sample(n = 100, parameters)
# Draw a histogram of the generated data
hist(sample, breaks = "FD", main = "Histogram of Generated Data")
# Function to find the maximum likelihood estimates of the distribution parameters
find_mle <- function(data) {
# Define the log-likelihood function
log_likelihood <- function(parameters) {
u <- parameters$u
o <- parameters$o
k <- parameters$k
w <- parameters$w
# Calculate the log-likelihood for the parameters (μ, σ, k)
log_likelihood <- sum(dweibull(data - u, shape = k, scale = o, log = TRUE))
# Calculate the log-likelihood for the parameters (w, k)
log_likelihood <- sum(dpareto(data, shape = k, scale = 1/w, log = TRUE))
} else {
stop("Invalid parameter values.")
}
return(-log_likelihood) # Return negative log-likelihood for maximization
}
# Find the maximum likelihood estimates using optimization
mle <- optim(parameters, log_likelihood)
return(mle$par)
}
# Find the maximum likelihood estimates of the distribution parameters
mle <- find_mle(sample)
Make sure to replace the example parameter values (μ, σ, k) with your actual parameter values or (w, k) if you're using the Pareto distribution. You can adjust the number of samples n as per your requirement.
This code generates a sample from the specified distribution using the given parameters. It then plots a histogram of the generated data and finds the maximum likelihood estimates of the distribution parameters using the generated sample. Finally, it prints the estimated parameters (μ, σ, k) or (w, k) in the output.

Derive truth table for the following Boolean expression:[X+Y(X −
+Y −
)]
Answers
The truth table for the Boolean expression `[X+Y(X −+Y −)]` is:
| X | Y | [X+Y(X NOR Y)] |
|---|---|---------------|
| 0 | 0 | 0 |
| 0 | 1 | 0 |
| 1 | 0 | 1 |
| 1 | 1 | 1 |
To derive the truth table for the Boolean expression `[X+Y(X −+Y −)]`, we need to consider all possible combinations of truth values for the variables X and Y and evaluate the expression for each combination.
Let's break down the expression step by step:
1. `[X −+Y −]` represents the logical NOR operation between X and Y, denoted as X NOR Y. Its truth table is as follows:
| X | Y | X NOR Y |
|---|---|---------|
| 0 | 0 | 1 |
| 0 | 1 | 0 |
| 1 | 0 | 0 |
| 1 | 1 | 0 |
2. Now, let's substitute the above expression in `[X+Y(X −+Y −)]`:
[X+Y(X NOR Y)]
3. The next step is to evaluate the expression `Y(X NOR Y)`, which represents the logical AND operation between Y and the result of the NOR operation (X NOR Y) from step 1. The truth table for this expression is as follows:
| X | Y | X NOR Y | Y(X NOR Y) |
|---|---|---------|-----------|
| 0 | 0 | 1 | 0 |
| 0 | 1 | 0 | 0 |
| 1 | 0 | 0 | 0 |
| 1 | 1 | 0 | 0 |
4. Finally, we substitute the above expression in [X+Y(X NOR Y)]:
[X+Y(X NOR Y)]
5. The expression `[X+Y(X NOR Y)]` represents the logical OR operation between X and the result of the previous expression `Y(X NOR Y)` from step 3. The truth table for the final expression is as follows:
| X | Y | X NOR Y | Y(X NOR Y) | [X+Y(X NOR Y)] |
|---|---|---------|-----------|---------------|
| 0 | 0 | 1 | 0 | 0 |
| 0 | 1 | 0 | 0 | 0 |
| 1 | 0 | 0 | 0 | 1 |
| 1 | 1 | 0 | 0 | 1 |
So, the truth table for the Boolean expression [X+Y(X −+Y −)] is:
| X | Y | [X+Y(X NOR Y)] |

| 0 | 0 | 0 |
| 0 | 1 | 0 |

Answers
Given that the equation of the line in the diagram is `y = 5 - x`. The line cuts the y-axis at P. So, the coordinates of point P are (0,5) and the gradient of the line is `-1`.
The equation of the line can be written as `y = -1x + 5`.Therefore, the y-intercept of the line is 5. Therefore, the coordinates of point P are (0,5).
To find the gradient of the line, we have to write the equation of the line in the form of `y = mx + c`.
We can rewrite `y = -1x + 5` as `y = (-1)x + 5`.From the above form of the equation, we can see that the gradient `m` is `-1`.Therefore, the gradient of line 1 is `-1`.Hence, the required answer is: Coordinates of point P is `(0,5)`.The gradient of the line is `-1`.

Determine the point of intersection of the following pairs of lines 2x-3y-4=-13 and 5x=-2y+25
Answers
The point of intersection of the two lines is (27.005, 12.67).
The point of intersection of the lines 2x-3y-4=-13 and 5x=-2y+25 can be found by solving the system of equations.
To find the point of intersection, we can solve the system of equations by setting the two equations equal to each other and solving for x and y.
2x-3y-4=-13
5x=-2y+25
We can begin by subtracting the second equation from the first:
2x-3y-4=-13
-5x=-2y+25
2x-5x=-13+25
-3y=-38
Finally, we can solve for y:
y=12.67
We can now substitute this value for y into either equation to find the value of x.
2x-3(12.67)-4=-13
2x-38.01-4=-13
2x=-54.01

Answers
A relative frequency table is used to display the proportion of variables, in a tabular form.
3.1% of the respondents responds always32.5% of the respondents responds never or rarely.(a) Draw the Relative Frequency
To do this, we simply divide the frequency of each response by the total frequency.
The total frequency is:
\(Total = 326 + 304 + 992 + 257 + 61\)
\(Total = 1940\)
So, the calculation of the relative frequency table is as follows:
\(Never = \frac{326}{1940}=0.168=16.8\%\)
\(Rarely = \frac{304}{1940}=0.157=15.7\%\)
\(Sometimes = \frac{992}{1940}=0.511=51.1\%\)
\(Most\ times = \frac{257}{1940}=0.132=13.2\%\)
\(Always = \frac{61}{1940}=0.031=3.1\%\)
The relative frequency table is:
\(\left[\begin{array}{ccc}{Response}&{Frequency}&{Relative\ Frequency}\\Never&326&16.8\%\\Rarely&304&15.7\%&Sometimes&992&51.1\%&Most\ Times&257&13.2\%&Always&61&3.1\%\end{array}\right]\)
(b) Percentage that responds always.
From the above calculation, we have:
\(Always = 3.1\%\)
Hence, 3.1% responds always
(c) Percentage that responds never or rarely.
From the above calculation, we have:
\(Never = 16.8\%\)
\(Rarely =15.7\%\)
So, we have:
\(Never\ or\ Rarely = Never + Rarely\)
\(Never\ or\ Rarely = 16.8\%+ 15.7\%\)
\(Never\ or\ Rarely = 32.5\%\)
Hence, 32.5% responds never or rarely.

a fair coin is flipped four times. findthe probability it will land up heads eachtime(b) the probability it will land the same way eachtime (slightly different from (a)).
Answers
The probability of getting heads each time is 1/16, and the probability of getting the same outcome (either heads or tails) each time is 1/8.
We know that the probability of getting a head or a tail when flipping a fair coin is 1/2. Let us use this fact to answer the given questions. The probability it will land the same way each time:
The probability of getting heads each time is (1/2) × (1/2) × (1/2) × (1/2) = 1/16.
The probability of getting tails each time is also 1/16.
Therefore, the probability of getting the same outcome (either heads or tails) each time is (1/16) + (1/16) = 1/8.
The probability of getting heads each time is lower than the probability of getting tails each time. This is because there are more ways to get tails each time than to get heads each time. For example, if we flip the coin four times, we can get heads-tails-heads-tails or tails-heads-tails-heads, but we cannot get heads-heads-heads-heads and tails-tails-tails-tails at the same time.
Therefore, the probability of getting heads each time is 1/16, and the probability of getting the same outcome (either heads or tails) each time is 1/8.

The probability that each individual light bulbs work is 0.6. Suppose that each light bulb works independently of the other light bulbs. What is the probability that none of the 4 light bulbs work?
Answers
The probability that none of the 4 light bulbs work is 0.0256, or approximately 2.56%.
Since each light bulb works independently of the others, we can treat the outcome of each bulb as a Bernoulli trial with a probability of success (working) p = 0.6 and a probability of failure (not working) q = 0.4.
To find the probability that none of the 4 light bulbs work, we need to find the probability of having 0 successful trials out of 4. This can be calculated using the binomial distribution:
P(X=0) = (4 choose 0) * (0.6)^0 * (0.4)^4 = 0.4^4 = 0.0256
Where (4 choose 0) is the number of ways to choose 0 successful trials out of 4, which is 1.
In summary, we can use the binomial distribution to find the probability that none of the 4 light bulbs work, since each bulb works independently of the others. Using this method, we find that the probability is 0.0256 or approximately 2.56%.
