If the base diameter of the sawdust pile is 35 feet when the height is 30 feet, then when it is 40 feet high, the diameter will be 46.7 feet, while the volume will be 68,545.37 feet³.

The volume refers to the capacity of a three-dimensional object.

The formula for volume with diameter and height is V = πd²h/4.

Base diameter of the sawdust pile = 35 feet

Height = 30 feet

Base diameter of the sawdust pile when the height is 40 feet = 46.7 feet

(35/30 x 40)

Given height = 40 feet

Computed base diameter = 46.7 feet

Volume = πd²h/4

= 22/7 x 46.7² x 40/4

The likelihood that the average tariff rate of 400 shipments of ethanol picked at random will be inside $80 of the average tariff rate of all shipments is roughly 0.789, or 78.9%.

The probability that an event will occur or that a proposition is true is quantified by probability theory, a branch of mathematics. A number from zero to one, where 0 approximately indicates how likely the event will happen and 1 generally indicates certainty, is the probability given an occurrence. In mathematics, probability is a measure of how likely an event is to take place. Probability levels can also be expressed as percent between 0 and 100 percent in addition to the numerals 0 to 1. the percentage of all outcomes out of all equally likely alternatives that lead to a specific occurrence, represented as a ratio.

To solve this problem, we need to use the central limit theorem, which states that the distribution of sample means is approximately normal, with mean equal to the population mean and a standard deviation determined by dividing the population's standard deviation by the sample size square root.

We are given that the standard deviation of the population of tariff rates is $1200. Let mu be the population mean tariff rate, and x-bar be the sample mean tariff rate. We want to find the probability that the sample mean is within $80 of the population mean, i.e., |x-bar - mu| <= $80.

Using the formula for the standard error of the mean, we have:

SE = sigma/sqrt(n) = $1200/sqrt(400) = $60

Now, we can standardize the variable z = (x-bar - mu)/SE, and find the probability of |z| <= 80/60 = 4/3 using a standard normal distribution table or calculator.

P(|z| <= 4/3) = 0.7887

Therefore, the probability that the mean tariff rate of 400 randomly selected railroad-car shipments of ethanol will be within $80 of the mean tariff rate of all railroad-car shipments of ethanol is approximately 0.789 or 78.9% (rounded to three decimal places).

Interpretation: Sampling error refers to the natural variation in sample statistics (such as the sample mean) that occurs due to chance, even when the sample is randomly selected and representative of the population. In this case, the probability of the sample mean tariff rate being within $80 of the population mean is high (78.9%), which suggests that the amount of sampling error in estimating the population mean using a sample of 400 observations is relatively small.

(2, 3) means we'll let x be 2 and y be 3. Let's solve both equations first:

y = -2x + 7

3 = -2(2) + 7

3 = -4 + 7

Therefore, a sharpening costs Dollar 1.85.

The US, Canada, Australia, and some nations in the Pacific, Caribbean, Southeast Asia, Africa, and South America all use the dollar as their primary unit of exchange. The word "$" is used to denote it.

Let's use $a for the sharpener's price. We can state that the price of a book is $a + 1.95 because it costs $1.95 more than a sharpening.

We are aware of the $26.10 total cost of 10 sharpeners and 2 books. This can be expressed as an equation:

10a + 2(a + 1.95) = 26.10

If we simplify this equation, we get:

12a + 3.90 = 26.10

3.90 less from each side results in:

12a = 22.20

By multiplying both sides by 12, you get:

a = 1.85

Therefore, a sharpening costs $1.85.

The solution set of f(x) > 0 is x ∈ (-2, 8).

To find the solution set of f(x) > 0, we need to first determine the critical values of x where f(x) changes sign.

Let's start by finding the domain of the function:

x² - 6x - 16 ≠ 0

We can solve for x by using the quadratic formula:

x = [6 ± √(6² + 4(16))]/2 = [6 ± √52]/2 = 3 ± √13

So the domain of f(x) is (-∞, 3 - √13) U (3 + √13, ∞).

Now let's factor the numerator and denominator of f(x):

f(x) = (x + 10)/[(x - 8)(x + 2)]

The critical points occur where the numerator or denominator of f(x) changes sign.

The numerator changes sign at x = -10, and the denominator changes sign at x = -2 and x = 8.

The monthly payment and total price paid by Antony at interest rate of 6.8% for vehicle is $362.59 and $21204.4 respectively.

Cost price of the car Antony decided to purchase = $19,000

Down payment =  20% of purchase value

Interest rate of amount to be finance = 6.8%

Time period of finance amount = 4 years

Down payment = 0.2 × $19,000

                         = $3,800

Amount that Anthony needs to finance,

Amount to finance = $19,000 - $3,800

                               = $15,200

The monthly payment , use the formula for the monthly payment on a loan,

M = P × r × (1 + r)ⁿ / ((1 + r)ⁿ - 1)

where M is the monthly payment,

P is the principal the amount to finance

r is the monthly interest rate

n is the total number of payments which is the number of years multiplied by 12

The monthly interest rate is 6.8% / 12 = 0.00567,

and the total number of payments is 4 × 12 = 48.

Substituting these values into the formula, we get,

⇒M = $15,200 × 0.00567 × (1 + 0.00567)⁴⁸ / ((1 + 0.00567)⁴⁸ - 1)

⇒M = $15,200 × 0.00567 × 1.3118 / (1.3118 -1)

⇒M = $15,200 × 0.00567 × 1.3118 / 0.3118

⇒M = 113.056 / 0.3118

⇒M ≈ $362.59

Anthony's monthly payment will be about $362.59

Total price that Anthony paid for his vehicle,

add up the down payment and the total amount of payments over the 4-year period.

Total price = $3,800 + ( $362.59 × 48)

                  = $21204.4

Therefore, the monthly payment and the total price at interest rate of 6.8% that Anthony paid for vehicle is $362.59 and $21204.4 respectively.

The expression for the velocity is v(t) = 30m/s

(a) x(t) = 30t

The velocity is the derivative of the position function with respect to time:

v(t) = dx/dt

Since x(t) = 30t, we have:

v(t) = d/dt (30t)

= 30

So the expression for velocity is v(t) = 30 m/s.

(b) x(t) = 7sin(30)

The velocity is the derivative of the position function with respect to time:

v(t) = dx/dt

Since x(t) = 7sin(30), we have:

v(t) = d/dt (7sin(30))

= 7cos(30) * d/dt (30t)

= 3.5cos(30)

So the expression for velocity is v(t) = 3.5cos(30) m/s.

(c) x(t) = ecos(701)

The velocity is the derivative of the position function with respect to time:

v(t) = dx/dt

Since x(t) = ecos(701), we have:

v(t) = d/dt (ecos(701))

= -e sin(701) * d/dt (701t)

= -701e sin(701t)

If two  lines intersect  at an angle of 90˚ or are perpendicular to each other, they form a right angle. A right angle is indicated by the symbol ∟Angle is always 90° or a right angle. The  opposite angle of 90° is the hypotenuse. The hypotenuse is always the longest side. The sum of the remaining two interior angles is  90°.  In a right-angled triangle, the side opposite  the 90-degree angle is called the hypotenuse, indicated by the letter "c". The sides adjacent to a 37 degree angle and a right angle are called "ab" and "bc" respectively.

The sketch of the graph of y = 1/f(x) is added as an attachment

To find the function equation, we need to determine the factors of the equation based on the zeros of the function.

Since the zeros of the function are at x = -5, -1, and 4, the factors of the equation will be:

(x + 5), (x + 1), and (x - 4)

Multiplying these factors together gives us:

f(x) = a(x + 5)(x + 1)(x - 4)

To find the value of the constant term a, we can use the fact that the graph passes through the point (0, -4):

-4 = a(0 + 5)(0 + 1)(0 - 4)

-4 = -20a

So, we have

a = 1/5

Therefore, the function equation is:

f(x) = 1/5(x + 5)(x + 1)(x - 4)

For the graph of y = 1/f(x), we have
