Answer:

I think its a cylinder and a pyramid

The contract between Gene and Hollis regarding the trail bike is most likely voidable due to the non-disclosure of the disconnected odometer.

Gene's failure to disclose that the odometer on the trail bike was disconnected 90,000 miles ago raises concerns of misrepresentation and fraud. Generally, when a seller fails to disclose material information that would significantly impact a buyer's decision-making process, it can render the contract voidable. In this case, the disconnection of the odometer and the significant difference between the displayed mileage and the actual mileage could be considered material information.

The non-disclosure of the disconnected odometer could be seen as a fraudulent act, as it involves intentional deception or misrepresentation. Fraudulent misrepresentation can provide grounds for the affected party (in this case, Hollis) to seek remedies such as rescission of the contract, seeking damages, or demanding a refund. The misrepresented mileage could significantly affect the value and condition of the trail bike, as well as Hollis' decision to purchase it.

It is important to note that contract laws can vary across jurisdictions, and specific circumstances may influence the legal outcome. Consulting with a legal professional familiar with the applicable laws and regulations in the relevant jurisdiction would provide the most accurate advice regarding the contract's enforceability and potential remedies available to Hollis.

The standard deviation of the monthly amount charged is 346.41

Step 1: Identify the values of a and b, where [a , b] is the interval over which the continuous uniform distribution is defined.

Since it takes between 300 and 1500 minutes to be seated at the restaurant, we have:

a = 300

b = 1500

Step 2: Calculate the variance using the formula Var(x) = \(\frac{(b-a)^{2} }{12}\)

Using the formula for the variance and the values identified in step 1

(a = 300 , b = 1500), we have:

Var(x) = \(\frac{(b-a)^{2} }{12}\)

         = \(\frac{(1500 - 300)^{2} }{12}\)

         = 1440000/12

         = 120,000

the variance is 120,000

Step 3: Calculate the standard deviation by taking the square root of the variance. σ = \(\sqrt{Var(x)}\)

The standard deviation is the square root of the result from step 2 (variance = 120,000)

σ = \(\sqrt{Var(x)}\)

σ = \(\sqrt{120000}\)

They rode 15 miles before replacing each horse.

Let's assume that each rider rode a different number of horses, denoted as x, y, and z respectively. Since they used a total of 16 horses, we have the equation x + y + z = 16.

Since they rode the same number of miles on each horse, let's denote the distance traveled by each horse as d. Therefore, the total distance covered by all the horses can be calculated as 16d.

We are given that the three riders rode a total of 240 miles. Therefore, we have the equation xd + yd + z*d = 240.

From the given information, we have two equations:

x + y + z = 16 (Equation 1)

xd + yd + z*d = 240 (Equation 2)

Since we need to find the number of miles they rode before replacing each horse, we need to find the value of d. To solve this system of equations, we can substitute one variable in terms of the others.

Let's assume x = 16 - y - z. Substituting this into Equation 2, we get:

(16 - y - z)d + yd + z*d = 240

Simplifying, we have:

16d - yd - zd + yd + zd = 240

16d = 240

d = 240/16

d = 15

N(t) approaches 550.

The equation N(t) = 550 / (1 + 49e^(-0.7t)) models the number of people in a town who have heard a rumor after t days. The equation describes the growth of the number of people who have heard the rumor over time. The e^(-0.7t) term in the denominator represents the rate of decay or the slowing down of the spread of the rumor as t increases. As t increases without bound, the exponential term approaches 0, so the fraction approaches 550 / (1 + 49 * 0) = 550 / 1 = 550.

This means that as time goes on, the number of people who have heard the rumor will approach 550, the limit or maximum value of N(t). This value is not limited by any of the factors mentioned in the options (b) to (e).

The value of the integral is -3ln(8)/8 + 21/8.

The summing of discrete data is indicated by the integration. To determine the functions that will characterise the area, displacement, and volume that result from a combination of small data that cannot be measured separately, integrals are calculated.

We can evaluate the integral using integration by parts:

Let u = ln(x) and dv = 3/x² dx. Then, du = 1/x dx and v = -3/x.

Using the formula for integration by parts, we have:

∫3ln(x)/x² dx = u*v - ∫v*du

= ln(x)*(-3/x) - ∫(-3/x)*1/x dx

= -3ln(x)/x + 3∫1/x² dx

= -3ln(x)/x - 3/x + C

where C is the constant of integration.

Now, we can evaluate the definite integral from 1 to 8:

∫1⁸ 3ln(x)/x² dx

= [-3ln(x)/x - 3/x]_1⁸

= [-3ln(8)/8 - 3/8] - [-3ln(1)/1 - 3/1]

= -3ln(8)/8 - 3/8 + 3

= -3ln(8)/8 + 21/8

The equation of the tangent line represents a straight line that passes through the point of tangency and has a slope of -16.

The slope of the tangent line to the graph of the function y = x^4 - 10x^2 + 9 at x = 1 can be found by taking the derivative of the function and evaluating it at x = 1. The equation of the tangent line can then be determined using the point-slope form.

Taking the derivative of the function y = x^4 - 10x^2 + 9 with respect to x, we get:

dy/dx = 4x^3 - 20x

To find the slope of the tangent line at x = 1, we substitute x = 1 into the derivative:

dy/dx (at x = 1) = 4(1)^3 - 20(1) = 4 - 20 = -16

Therefore, the slope of the tangent line is -16.

To find the equation of the tangent line, we use the point-slope form: y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope.

Given that the point of tangency is (1, y(1)), we substitute x1 = 1 and y1 = y(1) into the equation:

y - y(1) = -16(x - 1)

Expanding the equation and simplifying, we have:

y - y(1) = -16x + 16

Rearranging the equation, we obtain the equation of the tangent line:

y = -16x + (y(1) + 16)

To find the slope of the tangent line, we first need to find the derivative of the given function. The derivative represents the rate of change of the function at any point on its graph. By evaluating the derivative at the specific value of x, we can determine the slope of the tangent line at that point.

In this case, the given function is y = x^4 - 10x^2 + 9. Taking its derivative with respect to x gives us dy/dx = 4x^3 - 20x. To find the slope of the tangent line at x = 1, we substitute x = 1 into the derivative equation, resulting in dy/dx = -16.

The slope of the tangent line is -16. This indicates that for every unit increase in x, the corresponding y-value decreases by 16 units.

To determine the equation of the tangent line, we use the point-slope form of a linear equation, which is y - y1 = m(x - x1). We know the point of tangency is (1, y(1)), where x1 = 1 and y(1) is the value of the function at x = 1.

Substituting these values into the point-slope form, we get y - y(1) = -16(x - 1). Expanding the equation and rearranging it yields the equation of the tangent line, y = -16x + (y(1) + 16).

The equation of the tangent line represents a straight line that passes through the point of tangency and has a slope of -16.

The present value of the loan is found to be  approximately $70.28.

To find the present value of a loan, we can use the formula:

Present Value = Future Value / (1 + (interest rate * time))

Given that the future value is $1,321.17, the interest rate is 7.75%, and the time is 230 days, we can plug in these values into the formula:

Present Value = 1321.17 / (1 + (0.0775 * 230))

Calculating the expression in the parentheses first:

Present Value = 1321.17 / (1 + 17.8075)

Simplifying further:

Present Value = 1321.17 / 18.8075
