The maximum distance we can ride with $93.65 is 48 miles. For maximum distance, we can subtract the initial cost of $2 and divide the remaining amount by the additional cost per mile.

To find the maximum distance we can ride with $93.65, we need to determine the number of additional miles we can afford after paying the initial $2 for the first mile.Let's assume the maximum distance we can ride is x miles (including the first mile). The cost for x miles would be:

$2 + $1.95 * (x - 1)

We want this cost to be equal to or less than $93.65, so we can set up the following inequality:

2 + 1.95 * (x - 1) ≤ 93.65

Simplifying the inequality:

1.95x - 1.95 + 2 ≤ 93.65

1.95x + 0.05 ≤ 93.65

1.95x ≤ 93.6

x ≤ 93.6 / 1.95

x ≤ 48

Therefore, the maximum distance we can ride is 48 miles.

Step-by-step explanation:

Wayne's actual act score is 18

A z-score tells you where the score lies on a normal distribution curve.

A standard deviation is a measure of how dispersed the data is in relation to the mean.

Mean is the average of the given numbers and is calculated by dividing the sum of given numbers by the total number of numbers.

Given,

The mean = 21

Standard deviation =5

z-score = -0.6

We know z-score = (x-mean)/ Standard deviation

Substitute the values

-0.6 = \(\frac{x-21}{5}\)

x-21 = -0.6 ×5

x-21 = -3

x=-3+21

x=18

Hence, the Wayne's actual act score is 18

Answer:

1. 9 6/12

2. 4 3/12

Step-by-step explanation:

I did the math on it.

Answer:

3. 9 (6/12)

4. 4 (3/12)

Step-by-step explanation:

Question 3:

6 (2/6) × 1 (1/2)

multiply the whole number by the denominator

6 x 6 = 36 + 2 (numerator) = 38/6

2 x 1 = 2 + 1 = 3/2

(38/6) x (3/2)

multiply (3/2) by 3

3 x 3 = 9

2 x 3 = 6

38/6 x 9/6

38 x 9 = 342

6 x 6 =  36

19/2 = 9 (1/2) or 9 (6/12)

Question 4:

5 (2/3) × (3/4)

15 + 2 = 17

17/3 x 3/4

17 x 4 = 68

3 x 4 = 12

3 x 3 = 9

4 x 3 = 12

(68/12) x (9/12)

68 x 9 = 612

12 x 12 = 144

612/144 = 4 (1/4) or 4 (3/12)

A change in a population that is not related strictly to the size of the population can be described as a change in the demographic makeup of the population. This refers to changes in the characteristics of individuals within the population, such as age, gender, education level, and ethnicity.

For example, if a population experiences an influx of young adults, this would represent a change in the demographic makeup of the population, even if the overall size of the population remains the same.

Other factors that can contribute to a change in the population's makeup include migration patterns, changes in birth rates and mortality rates, and shifts in cultural or social norms. These changes can have significant impacts on a population, affecting everything from economic growth to social dynamics. Understanding demographic changes is therefore critical for policymakers and researchers seeking to address issues such as inequality, public health, and urban planning. By analyzing population trends and anticipating future changes, we can better prepare for the challenges and opportunities that lie ahead.

The statements K-means is extremely sensitive to cluster centroid initializations and Poor initialization can lead to slow convergence are true. Option A and option C are correct.

K-means Clustering is a vector quantization technique that seeks to split "n" observations into "k" clusters, with each observation referring to the cluster with the closest mean, which reflects a model of the cluster.

This means that the K-means algorithm recognizes the "k" number of centroids and then allocates every data point to the cluster with the fewest centroids.

Thus, the statements K-means is extremely sensitive to cluster centroid initializations and Poor initialization can lead to slow convergence are true. Option A and option C are correct.

Step-by-step explanation:

The standard error of the sample mean is 1.21.

Given;

Suppose a diet regimen for men results in an average weight loss of between 13. 4 and 18. 3 pounds, according to a 95% confidence interval. These findings were based on a group of 42 men who were classified as overweight at the beginning of the four-month trial.

A 95% confidence interval for a population mean is (13.4, 18.3)

Upper limit = 18.3

Lower limit = 13.4

Since population SD is unknown, this interval is constructed using the t distribution.

n = 42

c = 0.95

∴ α = 1 - c = 1 - 0.95 = 0.05

α/2 = 0.025

Also, d.f = n - 1 = 42 - 1 = 41

∴ ta/2.d.f =  ta/2.n-1  =  t0.025,41  =  2.02 . . . . use t table

Now,

The margin of error = (Upper limit - Lower limit)/2

                                 = (18.3 - 13.4)/2

                                 = 2.45

But,

Margin of error = ta/2.d.f-  * (s / \sqrt{} n)

Margin of error = ta/2.d.f-  * Standard error

2.45 = 2.02 * Standard error

Standard error = 1.2129

The expected value of m is the mean of the distribution of sample means. The correct option for the question is c) it is the mean of the distribution of sample means.

The expected value, also known as the mean or expectation, is a measure of the central tendency of a random variable. In other words, it refers to the theoretical mean of the distribution of a random variable. It is obtained by multiplying each possible outcome of a random variable by its probability of occurrence and then summing up all the products. The result is the expected value.

A sample mean is the arithmetic mean of a random sample of n observations drawn from a population. It is an unbiased estimate of the population mean. It is calculated by adding up all the observations in the sample and then dividing the sum by the sample size.

Sample standard deviation, also known as s, is a measure of the variability or dispersion of a random sample. It is the square root of the variance of the sample. It is calculated by taking the square root of the sum of the squared deviations from the sample mean divided by the sample size minus 1.

Therefore, option a) and option b) are incorrect as the expected value of m is not the sample mean or sample standard deviation. Option d) is also incorrect as the expected value of m is not the standard deviation of the distribution of sample means.

Evaluating the integral-  \(\int_0^1 (u+2)(u-3) du\) we get the simplified answer = -37/6.

Let's evaluate the integral as follows -

\(\int_0^1 (u+2)(u-3) du\)

now lets multiply the expression and we will get,  

\(= \int_0^1 u^2-u-6 d u\)

Distributing the integrals to each expression.

\(= \int_0^1 u^2 d u+\int_0^1-u d u+\int_0^1-6 d u\)

By the Power Rule, the integral of \($u^2$\) with respect to u is  \($\frac{1}{3} u^3$\).

\(= \left.\frac{1}{3} u^3\right]_0^1+\int_0^1-u d u+\int_0^1-6 d u\)

Since -1 is constant w.r.t u, move -1 out of the integral of the second term.

\(= \left.\frac{1}{3} u^3\right]_0^1 -\int_0^1u d u+\int_0^1-6 d u\)

By using the power rule, the integral of \($u^2$\) w.r.t to u is \($\frac{1}{2} u^2$\)

\(= \left.\left.\frac{1}{3} u^3\right]_0^1-\left(\frac{1}{2} u^2\right]_0^1\right)+\int_0^1-6 d u\)

Let's Combine \($\frac{1}{2}$\) and \($u^2$\).

\(= $$\left.\left.\frac{1}{3} u^3\right]_0^1-\left(\frac{u^2}{2}\right]_0^1\right)+\int_0^1-6 d u$$\)

Now, apply the constant rule,

\(= $$\left.\left.\left.\frac{1}{3} u^3\right]_0^1-\left(\frac{u^2}{2}\right]_0^1\right)+-6 u\right]_0^1$$\)

Substituting the limits and simplifying we get,

= -37/6

Hence, the simplified answer for the given integral \(\int_0^1 (u+2)(u-3) du\) is -37/6.

The value of given differential equation \(y' = y - x\) with the initial condition \(y(0) = 1.5\), on the interval \(0 \leq x \leq 1.5\), is \(y(1.5) = y_4 = 5.4296875\).

The differential equation we are given is \(y' = y - x\), with the initial condition \(y(0) = 1.5\). We are asked to approximate the solution on the interval \(0 \leq x \leq 1.5\) with a step size of \(h = 0.5\), and we want to achieve an accuracy of \(e = 0.0001\).

We start by calculating the first two values, \(y_0\) and \(y_1\), using the formula:

\(y_1 = y_0 + h \cdot f(x_0, y_0)\)

Here, \(h\) represents the step size, \(f(x, y)\) represents the derivative \(y'\) in terms of \(x\) and \(y\), and \((x_0, y_0)\) is the initial condition.

Using the given values, we can calculate \(y_1\) as:

\(y_1 = 1.5 + 0.5 \cdot (1.5 - 0) = 2.25\)

Next, we calculate \(y_2\) using the same formula:

\(y_2 = y_1 + h \cdot f(x_1, y_1)\)

Substituting the values \(x_1 = 0.5\) and \(y_1 = 2.25\), we get:

\(y_2 = 2.25 + 0.5 \cdot (2.25 - 0.5) = 3.375\)

Similarly, we can calculate \(y_3\) and \(y_4\) as:

\(y_3 = 3.375 + 0.5 \cdot (3.375 - 1) = 4.3125\)

\(y_4 = 4.3125 + 0.5 \cdot (4.3125 - 1.5) = 5.4296875\)

So, the value of \(y\) at \(x = 1.5\) is \(y(1.5) = y_4 = 5.4296875\).

Using Euler's method with a step size of \(h = 0.5\) and an accuracy of \(e = 0.0001\), the solution to the given differential equation \(y' = y - x\) with the initial condition \(y(0) = 1.5\), on the interval \(0 \leq x \leq 1.5\), is \(y(1.5) = y_4 = 5.4296875\).
