The sample standard deviation of the heights (in inches) of 10 adult males is approximately 1.464 inches.

To find the sample standard deviation of the heights of the 10 adult males, follow these steps:

1. Calculate the mean (average) height:

(70+72+71+70+69+73+69+68+70+71) / 10 = 703 / 10 = 70.3 inches.

2. Subtract the mean from each height and square the result:

\([(70-70.3)^2, (72-70.3)^2, ... (71-70.3)^2].\)

3. Calculate the sum of these squared differences:

0.09+2.89+0.49+0.09+1.69+7.29+1.69+5.29+0.09+0.49 = 19.31.

4. Divide the sum by (n-1), where n is the sample size: \(19.31 / (10-1) = 19.31 / 9 = 2.145.\)
5. Take the square root of the result: √2.145 = 1.464 (rounded to 3 decimal places).

The sample standard deviation of the heights of the 10 adult males is approximately 1.464 inches.

Answer:

60 minutes

Step-by-step explanation:

Latitude and longitude are measuring lines used for locating places on the surface of the Earth. They are angular measurements, expressed as degrees of a circle. A full circle contains 360°. Each degree can be divided into 60 minutes, and each minute is divided into 60 seconds.

One degree of latitude is equal to approximately 60 nautical miles or 69 statute miles. Since a minute of latitude is one-sixtieth of a degree, it follows that one degree of latitude is equal to 60 minutes.

This means that there are 60 nautical miles or 69 statute miles between two points that differ by one minute of latitude.

The minute of latitude is a widely used unit for measuring distances on Earth, particularly in navigation and aviation. It allows for precise calculations and is crucial for determining positions accurately. Understanding the relationship between degrees of latitude and minutes helps in determining distances, estimating travel times, and ensuring accurate navigation across the globe.

The number of iterations increases. If there is a significant difference between the two solutions, we may need to investigate the numerical method used or check for errors in our analytical solution.

Step-by-step explanation:

The differential equation is missing in your question. However, I will give a general overview of how to solve a differential equation numerically using Euler's method and how to find an analytical solution.

Numerical Solution using Euler's Method:

Suppose we have a first-order differential equation of the form y' = f(x, y), where y' represents the derivative of y with respect to x. To solve this numerically using Euler's method, we need to start with an initial condition y(x0) = y0, and we want to find the value of y at some other point x1 = x0 + h.

The Euler's method involves approximating the derivative y' by the difference quotient (y1 - y0) / h, where y1 is the value of y at x1. Rearranging this equation, we get:

y1 = y0 + h * f(x0, y0)

Using this equation, we can iteratively compute the value of y at different points by using the previous value of y. For example, to find y2, we can use the equation:

y2 = y1 + h * f(x1, y1)

We continue this process until we reach the desired endpoint.

Analytical Solution:

An analytical solution to a differential equation is an explicit expression for y(x) that satisfies the differential equation for all values of x. To find an analytical solution, we may use techniques such as separation of variables, integrating factors, or other methods specific to the type of differential equation.

For example, if we have a differential equation of the form y' = k * y, where k is a constant, we can use separation of variables to obtain:

dy / y = k * dx

Integrating both sides, we get:

ln|y| = k * x + C

where C is an arbitrary constant of integration. Solving for y, we get:

y = Ce^(kx)

where C = ±e^C is a constant determined by the initial condition.

Comparison of Solutions:

Once we have the numerical and analytical solutions, we can compare them by plotting the graphs of y(x) for each method. If the numerical solution was computed with a small enough step size, it should converge to the analytical solution as the number of iterations increases. If there is a significant difference between the two solutions, we may need to investigate the numerical method used or check for errors in our analytical solution.

To find the volume of a box using the formula Volume = length x width x height, you need to multiply the three dimensions of the box together. The resulting number will be the amount of space that the box occupies in three-dimensional space.

The volume of a box is a measurement of the amount of space it takes up in three dimensions. To calculate the volume of a box, you need to know its length, width, and height. These dimensions are typically measured in units such as inches, feet, meters, or centimeters. Once you have measured these dimensions, you can use the formula Volume = length x width x height to calculate the box's volume.

To apply the formula, simply multiply the length of the box by its width and then by its height. The resulting number will be the volume of the box, which is typically expressed in cubic units such as cubic inches, cubic feet, or cubic meters. It's important to make sure that you are using the same units of measurement for all three dimensions when calculating the volume of a box. If the dimensions are not in the same units, you will need to convert them before calculating the volume.

In summary, the formula Volume = length x width x height can be used to find the volume of a box. To do this, you need to multiply the length, width, and height of the box together. The resulting number will be the amount of space that the box occupies in three-dimensional space, expressed in cubic units.

In mathematics and statistics, the term "mean" refers to the average of a set of variables. There are various ways to determine the mean, including geometric means, harmonic means, and simple arithmetic means (putting the numbers together and dividing the result by the number of observations).

The mean of the normal distribution represented by the given data can be computed as follows:

Find the sum of the values:

sum = 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 = 36

To answer this question, we need to use the concept of the normal distribution and the given mean and standard deviation. The mean time for the pain reliever to begin reducing symptoms is 30 minutes.

To find the probability that it will take the medication between 32 and 37 minutes to begin to work, we'll use the mean, standard deviation, and the properties of a normal distribution.

Step 1: Calculate the z-scores for 32 and 37 minutes.
The z-score is the number of standard deviations a value is from the mean. The formula for the z-score is:
z = (X - μ) / σ
where X is the value, μ is the mean, and σ is the standard deviation.
For 32 minutes:
z1 = (32 - 30) / 8.7 ≈ 0.23
For 37 minutes:
z2 = (37 - 30) / 8.7 ≈ 0.80

Step 2: Find the probabilities corresponding to the z-scores.
You can use a z-table or an online calculator to find the probabilities for each z-score.
For z1 = 0.23, the probability is ≈ 0.5910
For z2 = 0.80, the probability is ≈ 0.7881

Step 3: Calculate the probability between the two z-scores.
Subtract the probability of z1 from the probability of z2:
P(32 < X < 37) = P(z2) - P(z1) = 0.7881 - 0.5910 ≈ 0.1971

So, the probability that it will take the medication between 32 and 37 minutes to begin reducing symptoms is approximately 19.71%.

Kennedy made her initial error in Step 4 of the completion of the square process. In this step, she incorrectly computed 3 - 6 as 133 instead of the correct value of -3.

Completing the square is a method used to solve quadratic equations by manipulating the equation to form a perfect square trinomial. In Kennedy's case, she was attempting to solve the equation 63 + 3 = 0. However, her error in Step 4 caused the subsequent steps to be based on an incorrect value. As a result, the final answer she obtained was incorrect.

This mistake propagated throughout the subsequent steps, leading to an incorrect final answer. By miscalculating this term, Kennedy introduced an error that affected the outcome of the equation.

It is crucial to be meticulous and accurate when applying mathematical procedures such as completing the square. A small mistake in one step can lead to significant errors down the line. By double-checking calculations and carefully following the steps, Kennedy could identify and rectify her error, ultimately arriving at the correct solution.
