The results of the survey on public transportation use may be biased in several ways. First, the sample may not be representative of the entire population of the US residents who use public transportation. For example, the survey may have only included adults in a particular city or region, which may not reflect the transportation habits of people living in other parts of the country.

Another source of bias may be non-response bias, where people who did not respond to the survey have different public transportation habits than those who did. For example, people who are less likely to use public transportation may also be less likely to respond to the survey, which would skew the results towards a higher percentage of public transportation users.
There may also be biases in the survey design or administration that could impact the results. For instance, the questions may have been phrased in a way that encouraged respondents to overestimate their use of public transportation. Or, the survey may have been conducted during a time when there was increased or decreased public transportation use due to external factors, such as a holiday or major event.

Overall, it is important to interpret survey results with caution and consider potential sources of bias. Additional research and analysis may be needed to obtain a more accurate estimate of public transportation use among all US residents.

Answer:

1.451 seconds.  Hurry.

Step-by-step explanation:

The position(height, h) of the foot ball will be given by the equation:

h = -32.2t^2 + 45t + 2.5

The term -32.2t^2 consists of the acceleration caused by gravity at Earth's surface ( -32 ft/sec^2) and the term +45t accounts for the initial velocity.  The + is assigned since the ball is moving vertically from ground.  The negative sign in -32t^2 is due to the acceleration being towards ground.  The term 2.5 accounts for the fact that the initial height of the ball is 2.5 feet above ground.

We can either calculate or graph with this function to find the time the ball spends in the air:

Calculate:

h = -32.2t^2 + 45t + 2.5

We need a value of t that would cause h to be 5.5 feet, the level it was caught:

5.5 = -32.2t^2 + 45t + 2.5

-32.2t^2 + 45t + 2.5 = 5.5

-32.2t^2 + 45t -3.0  = 0

Solve for t using the quadratic formula.  I get a value of 1.33 seconds.

Graph:

See the attached graph.  It confirms the 1.33 second value

The final equation for the tangent plane to the graph of f at the point (a, b) is z = 2e^a(x - a) - y + 2e^a - 2b. This equation represents the plane that is tangent to the graph of f at the specified point (a, b).

To find the equation for the tangent plane to the graph of the function f(x, y) = 2e^x - y at a given point (x0, y0), we need to calculate the partial derivatives of f with respect to x and y at that point.

The partial derivative of f with respect to x, denoted as ∂f/∂x or fₓ, represents the rate of change of f with respect to x while keeping y constant. Similarly, the partial derivative of f with respect to y, denoted as ∂f/∂y or fᵧ, represents the rate of change of f with respect to y while keeping x constant.

Let's calculate these partial derivatives:

fₓ = d/dx(2e^x - y) = 2e^x

fᵧ = d/dy(2e^x - y) = -1

Now, we have the partial derivatives evaluated at the point (x0, y0). Let's assume our point of interest is (a, b), where a = x0 and b = y0.

At the point (a, b), the equation for the tangent plane is given by:

z - f(a, b) = fₓ(a, b)(x - a) + fᵧ(a, b)(y - b)

Substituting fₓ(a, b) = 2e^a and fᵧ(a, b) = -1, we have:

z - f(a, b) = 2e^a(x - a) - (y - b)

Now, let's substitute f(a, b) = 2e^a - b:

z - (2e^a - b) = 2e^a(x - a) - (y - b)

Rearranging and simplifying:

z = 2e^a(x - a) - (y - b) + 2e^a - b

The final equation for the tangent plane to the graph of f at the point (a, b) is z = 2e^a(x - a) - y + 2e^a - 2b.

This equation represents the plane that is tangent to the graph of f at the specified point (a, b).

Both parts (a) and (b) have the same number of ways to arrange the smoothies, which is 21! (21 factorial).

(a) To arrange 21 indistinguishable strawberry smoothies in a 21x21 grid such that no two smoothies are in the same row or column, we can consider the problem as placing 21 objects (smoothies) into 21 slots (grid compartments).

The first smoothie can be placed in any of the 21 slots in the first row. Once it is placed, the second smoothie can be placed in any of the 20 remaining slots in the first row or in any of the 20 slots in the second row (excluding the column where the first smoothie is placed). Similarly, the third smoothie can be placed in any of the 19 remaining slots in the first or second row or in any of the 19 slots in the third row (excluding the columns where the first and second smoothies are placed), and so on.

Therefore, the total number of ways to arrange the strawberry smoothies in the grid without repetition is:

21 * 20 * 19 * ... * 3 * 2 * 1 = 21! (21 factorial).

(b) In this case, Luciano has 21 distinct smoothies to arrange in the 21x21 grid such that no two smoothies are in the same row or column.

The first smoothie can be placed in any of the 21 slots in the first row. Once it is placed, the second smoothie can be placed in any of the 20 remaining slots in the first row or in any of the 20 slots in the second row (excluding the column where the first smoothie is placed). Similarly, the third smoothie can be placed in any of the 19 remaining slots in the first or second row or in any of the 19 slots in the third row (excluding the columns where the first and second smoothies are placed), and so on.

Researchers conducted a study and obtained  the p-value is 0.30, which is higher than the common significance level of 0.05. This means that there is not enough evidence to reject the null hypothesis, but it does not mean that the null hypothesis is accepted.

Hence this statement is false.

When researchers conduct a study and obtain a p-value, they use it to make a decision regarding the null hypothesis.

However, a high p-value does not provide evidence to accept the null hypothesis.

Instead, it indicates that there is not enough evidence to reject the null hypothesis.
1. Researchers start with a null hypothesis (H0), which is a statement that there is no effect or relationship between variables being studied.

They also have an alternative hypothesis (H1), which is a statement that there is an effect or relationship between variables.
2. They collect data and perform statistical tests to calculate the p-value, which represents the probability of observing the test results (or more extreme results) assuming the null hypothesis is true.
3. The p-value is then compared to a pre-determined significance level (alpha), commonly set at 0.05 or 5%.

If the p-value is less than the significance level, researchers reject the null hypothesis in favor of the alternative hypothesis.
4. In this case, the p-value is 0.30, which is higher than the common significance level of 0.05.

This means that there is not enough evidence to reject the null hypothesis, but it does not mean that the null hypothesis is accepted.
5. Instead, researchers should say that they "fail to reject" the null hypothesis, meaning they cannot confidently conclude that the alternative hypothesis is true based on the data and analysis.

It will take approximately 39.532 days for $9500 to earn $800 at an annual interest rate of 8.25%.

To find the number of days it will take for $9500 to earn $800 at an annual interest rate of 8.25%, we need to use the formula for simple interest:

Interest = Principal * Rate * Time

In this case, we are given the interest ($800), the principal ($9500), and the annual interest rate (8.25%). We need to solve for time.

Let's denote the time in years as "t". Since we're looking for the number of days, we'll convert the time to a fraction of a year by dividing by 365 (assuming a standard 365-day year).

$800 = $9500 * 0.0825 * (t / 365)

Simplifying the equation:

800 = 9500 * 0.0825 * (t / 365)

Divide both sides by (9500 * 0.0825):

800 / (9500 * 0.0825) = t / 365

Simplify the left side:

800 / (9500 * 0.0825) ≈ 0.1083

Now, solve for t by multiplying both sides by 365:

0.1083 * 365 ≈ t

t ≈ 39.532

Therefore, it will take approximately 39.532 days for $9500 to earn $800 at an annual interest rate of 8.25%.

The time the ball stays in the air is approximately 2.29 seconds and the ball can be seen 2.1 seconds after its thrown.

c)To find the amount of time the ball stays in the air, we need to find when it hits the ground, i.e., when its height is equal to 0. So, we need to solve the equation:

-16t^2 + 801 + 30 = 0

By using the quadratic formula or factoring, we can find that:

t = sqrt((801+30)/(-16)) = sqrt(831/-16) = sqrt(52.0625) = 2.29 seconds

So, the ball stays in the air for approximately 2.29 seconds.

d) To find the interval of time the ball can be seen from the ground, we need to find when its height is greater than or equal to 100 feet. This can be determined by solving the inequality:

-16t^2 + 801 + 30 >= 100

Solving for t:

t >= sqrt((100-801-30)/(-16)) = sqrt((-701)/(-16)) = sqrt(44.0625) = 2.1 seconds

So, the ball can be seen from the ground for approximately 2.1 seconds after it's thrown.
