The minimum percentage of commuters with commute times between 3 minutes and 51.6 minutes, we can use Chebyshev's Inequality with k = (51.6 - 27.3) / 8.1. The resulting percentage is at least (1 - 1/k^2).

Chebyshev's Inequality states that for any distribution (regardless of its shape), at least (1 - 1/k^2) of the data falls within k standard deviations of the mean, where k is any positive constant greater than 1.

For the first question, the range between $2.94 and $3.18 corresponds to 1 standard deviation from the mean price of gasoline stations. Therefore, using Chebyshev's Inequality, at least (1 - 1/1^2) = 0% of the gasoline stations would fall within this range.

For the second question, within 1.5 standard deviations of the mean, we can calculate the minimum percentage by using k = 1.5 in Chebyshev's Inequality. This gives us at least (1 - 1/1.5^2) = 55.56% of the commuters in Boston having a commute time within 1.5 standard deviations of the mean.

To determine the commute times within 1.5 standard deviations of the mean, we can calculate the range by multiplying the standard deviation (8.1 minutes) by 1.5 and subtracting this value from and adding it to the mean. So, the range would be (27.3 - 1.5 * 8.1) to (27.3 + 1.5 * 8.1), which is approximately 15.15 minutes to 39.45 minutes.

A hippopotamus had a mass of 32.7 kg at birth. the hippopotamus's mass increased by approximately 167.1% over the two-month period.

To calculate the percentage increase in the hippopotamus's mass over the two-month period, we can use the following formula:

Percentage increase = ((New mass - Original mass) / Original mass) * 100

Given that the original mass (birth weight) was 32.7 kg and the new mass (after two months) was 87.4 kg, we can substitute these values into the formula:

Percentage increase = ((87.4 - 32.7) / 32.7) * 100

Calculating this expression:

Percentage increase = (54.7 / 32.7) * 100 ≈ 167.1%

Therefore, the hippopotamus's mass increased by approximately 167.1% over the two-month period. Rounding to the nearest 1%, the percentage increase is 167%.

The price is $5.39, rounded to 2 decimal places.

To determine the price of a put option with the same exercise price, we can use the put-call parity formula:

Put Price = Call Price - Stock Price + Present Value of Exercise Price

Stock Price (S) = $76

Call Price (C) = $3.80

Exercise Price (X) = $78

Risk-Free Interest Rate (r) = 2.5% per year (compounded continuously)

Time to Expiration (t) = 3 months = 3/12 = 0.25 years

First, we need to calculate the present value of the exercise price using the continuous compounding formula:

PV = X * \(e^{(-r*t)}\)

PV = $78 * \(e^{(-0.025 * 0.25)}\)

Next, we can use the put-call parity formula:

Put Price = Call Price - Stock Price + PV

Substituting the given values:

Put Price = $3.80 - $76 + PV

Finally, we calculate the final result:

Put Price = $3.80 - $76 + PV

Now, perform the intermediate calculations to find the present value (PV) and calculate the final answer, rounding it to 2 decimal places.

To calculate the present value (PV), we use the formula:

PV = X * \(e^{(-r * t)}\)

where:

X = Exercise Price = $78

r = Risk-Free Interest Rate = 2.5% per year (compounded continuously)

t = Time to Expiration = 0.25 years

First, let's calculate the exponent:

(-r * t) = (-0.025 * 0.25) = -0.00625

Next, we calculate the present value:

PV = $78 *

Using a calculator, we find:

PV ≈ $77.59

Now, we can calculate the price of the put option:

Put Price = Call Price - Stock Price + PV

Put Price = $3.80 - $76 + $77.59

Put Price ≈ $5.39

Therefore, the price of the put option with the same exercise price is approximately $5.39, rounded to 2 decimal places.

Using the Mean Value Theorem to find values for the inequality below, we get : Answer: 12 ≤ f(2) - f(-2) ≤ 20

By the Mean Value Theorem, if a function f(x) is continuous on the closed interval [a, b] and differentiable on the open interval (a, b), then there exists at least one value c in the interval (a, b) such that:

\(\[f'(c) = \frac{f(b) - f(a)}{b - a}\]\)

In this case, we are given that 3 ≤ f'(x) ≤ 5 for all values of x.

Let's apply the Mean Value Theorem to the interval [-2, 2]. Since f(x) is continuous on [-2, 2] and differentiable on (-2, 2), there exists a value c in (-2, 2) such that:

\(\[f'(c) = \frac{f(2) - f(-2)}{2 - (-2)} = \frac{f(2) - f(-2)}{4}\]\)

Given that 3 ≤ f'(x) ≤ 5 for all values of x, we can rewrite this inequality using the value of c:

3 ≤ f'(c) ≤ 5

Multiplying both sides of the inequality by 4, we get:

12 ≤ 4f'(c) ≤ 20

Since f'(c) = (f(2) - f(-2))/4, we can substitute this expression back into the inequality:

\(\[12 \leq 4 \cdot \frac{f(2) - f(-2)}{4} \leq 20\]\)

Simplifying, we have:

12 ≤ f(2) - f(-2) ≤ 20

Therefore, the values for the inequality are:

12 ≤ f(2) - f(-2) ≤ 20

The sum of the probabilities of all values of x must be equal to 1, as this is the total probability of all possible outcomes.

The probability distribution of a discrete random variable x is a mathematical function that provides the probabilities of occurrence of different possible outcomes of x. In probability theory, the sum of the probabilities of all values of x must be equal to 1, since this is the total probability of all possible outcomes. This is because the value of 1 represents the certainty of the event occurring, and if the sum of the probabilities of all the possible outcomes is not equal to 1, the probability of any individual outcome cannot be known. The sum of the probabilities of all values of x must be equal to 1 or it cannot be used to calculate the probability of any individual outcome. The probability of any individual outcome is determined by multiplying the probability of each outcome by the sum of all probabilities.

The second-order partial derivatives of f(x, y) = 6x + 2y + 3xy are: ∂²f/∂x² = 0, ∂²f/∂y² = 0, ∂²f/∂x∂y = 3, ∂²f/∂y∂x = 3.

To find the second-order partial derivatives of the function f(x, y) = 6x + 2y + 3xy, we need to differentiate the function twice with respect to each variable.

First, we find the first-order partial derivatives:

∂f/∂x = 6 + 3y,

∂f/∂y = 2 + 3x.

Next, we differentiate these partial derivatives with respect to their corresponding variables to obtain the second-order partial derivatives:

∂²f/∂x² = 0 (since the derivative of a constant is zero),

∂²f/∂y² = 0 (also zero as it is a constant),

∂²f/∂x∂y = 3,

∂²f/∂y∂x = 3.

The second-order partial derivatives ∂²f/∂x∂y and ∂²f/∂y∂x are equal because the function is differentiable, and the mixed partial derivatives are symmetric. Therefore, we have ∂²f/∂x∂y = ∂²f/∂y∂x = 3.

We know that the formula to find the electric potential V = KQ/R,

where K is Coulombs constant, Q is the charge, and R is the radius of the circle.  

According to the question,

The radius of the circle formed by the plastic rod on bending = 8.20 cm

(Converting cm to m by dividing by 100)               = (8.20)/100 = 0.082m

We know that Coulombs constant (K) =  8.99 × 10 ^ 9 N m^2/C^2

It is given that along one quarter of its circumference (Q1) =  +3.00 pC

and along the remaining circumference, the charge (Q2) = -6Q1

Therefore, electric potential (V) = K (Q1+KQ2) /R

= (8.99 × 10 ^ 9) (Q1 + (-6Q1)) / 0.082 = (8.99 × 10 ^ 9) (-5Q1)/ 0.082

The p-value is less than 0.1, so there is evidence at the 0.1 level that the doors are either too long or too short.

To determine if there is evidence that the doors are either too long or too short, we can conduct a hypothesis test.

Let's assume the null hypothesis (H0) is that the mean height of the doors is equal to 2058 millimeters, and the alternative hypothesis (Ha) is that the mean height of the doors is not equal to 2058 millimeters.

We can use a t-test to compare the sample mean of 2072 millimeters to the population mean of 2058 millimeters, given the sample size of 18 and the standard deviation of 33.

Calculating the test statistic using the formula:
t = (sample mean - population mean) / (standard deviation / sqrt(sample size))

Substituting the values:
t = (2072 - 2058) / (33 / sqrt(18))

Calculating the p-value associated with this test statistic, we find that it is less than 0.1.

Your total vacation budget would be $280, considering the $160 spent on groceries and the estimated cost of eating out 3 times at $40 per meal from linear equation concept.

For your vacation at the beach, you have already spent $160 on groceries for the week. In addition, you anticipate spending $40 each time you eat out.

To determine your overall budget for the vacation, you need to consider how many times you plan to eat out during the week. Let's say you plan to eat out 'x' number of times.

Since each time you eat out costs $40, the total amount spent on eating out can be represented by the equation:

Total spent on eating out = $40 * x

Adding this to the amount spent on groceries, the total vacation budget can be calculated as:

Total budget = Amount spent on groceries + Total spent on eating out

Total budget = $160 + ($40 * x)

For example, if you plan to eat out 3 times during the week, the calculation would be:

Total budget = $160 + ($40 * 3)

Total budget = $160 + $120

Total budget = $280

In this case, your total vacation budget would be $280, considering the $160 spent on groceries and the estimated cost of eating out 3 times at $40 per meal.

The total budget will vary depending on the number of times you plan to eat out. By adjusting the value of 'x', you can calculate the specific total budget for your vacation.

\(\huge\boxed{Q = 110 \textdegree, \ ST = 9 \ \text{ft}}\)

Step-by-step explanation:

When we reflect and transform a figure, the angle lengths nor the side lengths are touched. The side length only changes if we dilate or stretch the figure, and the angle length only changes if we stretch the figure.

Therefore, we know the information is going to be the exact same. We just have to figure out what corresponds to what from JKLM to QTSR.

If we reflect a figure across a horizontal reflection line through its center, the figure will just flip sides. M will be J, L will be K, etc.

When we translate this down, nothing changes except its position. So we can pretend these two shapes are right on top of each other for now.

When we move these right on top of each other, we can see that Angle J overlaps with Angle Q. Since they don't have any weird intersects, we know that angle J will be equal to Angle Q. Since we already know J is 110°, we know Q is also 110°.

When we move it on top, we also see that KL overlaps with ST perfectly. Since we know KL is 9, that must mean ST is also 9.
