D = 8.3 mm

The radius of the circle is 4.15 mm.

The radius and diameter are both important properties of a circle, and they are related to each other. The diameter is the distance across the circle through its center, while the radius is the distance from the center to any point on the circle. The radius and diameter are related by the formula

D = 2r

Where "D" is the diameter and "r" is the radius.

To calculate the radius of a circle given its diameter, we use the formula

r = D/2

Where "r" is the radius and "D" is the diameter. The formula tells us that the radius is equal to half of the diameter.

In this case, we are given that the diameter is 8.3 mm. To find the radius, we simply substitute this value into the formula and solve for "r"

r = D/2

r = 8.3 mm/2

r = 4.15 mm

Therefore, the radius of the circle is 4.15 mm.

Assuming that the cost price in the question is 80K with a 65% profit percentage on cost price, the selling price of the shoe is 132K.

Given, Cost Price (CP) of the shoe = 80K or 80,000

           Profit % = 65%

From the formula, we know,

             Profit % = (Profit / Cost Price) * 100

Inserting given values in the formula, we get,

             ==>  65 = (Profit / 80,000) *100

                or, 65 = Profit / 800

Therefore, Profit = 65 * 800

                           = 52,000

In the case of Profit, Selling Price = Cost Price + Profit

Hence, the Selling Price of the shoe is = 80,000 + 52,000

                                                                 = 132,000 or 132K (Answer)

To test the claim that more than one-third of employers have sent an employee home for inappropriate attire, we can set up the following null and alternative hypotheses:

Null hypothesis: p ≤ 1/3

Alternative hypothesis: p > 1/3

where p is the true proportion of all employers who have sent an employee home for inappropriate attire.

We can use the sample proportion, 964/2765 = 0.349, as an estimate of the true proportion p. To test the hypotheses, we can calculate the test statistic z as:

z = (p - 1/3) / sqrt((1/3)*(2/3)/n)

where n is the sample size (2765).

Plugging in the values, we get:

z = (0.349 - 1/3) / sqrt((1/3)*(2/3)/2765) = 4.28

Using a standard normal distribution table or calculator, the P-value for this test is less than 0.0001 (or approximately 0.0000 when rounded to four decimal places), indicating strong evidence against the null hypothesis.

Therefore, we can reject the null hypothesis and conclude that there is convincing evidence to support the claim that more than one-third of employers have sent an employee home for inappropriate attire.

On that day, 241 adults and 44 children swam at the public pool.

Let's use a system of equations to solve the problem:

From the problem, we know that:

x + y = 285 (the total number of people who swam)

1.25x + 2.5y = 657.5 (the total amount collected in admission fees)

We can use the first equation to solve for x in terms of y:

x = 285 - y

Substituting this expression for x into the second equation, we get:

1.25(285 - y) + 2.5y = 657.5

Expanding and simplifying, we get:

356.25 - 1.25y + 2.5y = 657.5

1.25y = 301.25

y = 241

Substituting this value of y into the equation x + y = 285, we get:

x + 241 = 285

x = 44

Therefore, there were 44 children and 241 adults who swam at the public pool that day.

Answer: To evaluate the line integral ∫CF⋅dr, we first need to parameterize the path C in terms of a single variable, say t. The parameterization of C is given by:

r(t) = (t^3, -3t^2, 2^t), 0 ≤ t ≤ 1

We can then write the differential of the path as:

dr = (3t^2, -6t, 2^t ln(2)) dt

Next, we evaluate the dot product F ⋅ dr along the path C:

F(r(t)) ⋅ dr = ⟨5sin(t^3), -4cos(-3t^2), 10t^3(2^t)⟩ ⋅ ⟨3t^2, -6t, 2^t ln(2)⟩ dt

= 15t^2 sin(t^3) + 24t cos(3t^2) + 20t^3 (2^t) ln(2) dt

Finally, we integrate this expression over the interval 0 ≤ t ≤ 1 to get the value of the line integral:

∫CF ⋅ dr = ∫0^1 (15t^2 sin(t^3) + 24t cos(3t^2) + 20t^3 (2^t) ln(2)) dt

This integral cannot be evaluated exactly, but we can use numerical integration to approximate the value. Using a numerical integration tool, the value of the line integral is approximately equal to 11.108.

Therefore:

∫CF ⋅ dr ≈ 11.108

The correct three equations that can be used to solve for the angle of elevation () from the bottom of the hill to the top of the hill are,

⇒ tan θ = 550 / 3050

⇒ sin θ = 550 / 3600

⇒ cos θ = 3050/ 3600

We have to given that;

A 3,050 foot long road travels directly up a 550 foot tall hill.

Now, We can formulate;

1) In this case, the opposite side is the height of the hill 550 feet and the adjacent side is the length of the road 3,050 feet.

So, the equation becomes;

⇒ tan θ = 550 / 3050

2)  In this case, the opposite side is the height of the hill 550 feet and the hypotenuse is the length of the road plus the height of the hill,

3050 + 550 = 3600 feet

So, the equation becomes;

⇒ sin θ = 550 / 3600

3)  In this case, the adjacent side is the length of the road 3050 feet and the hypotenuse is the length of the road plus the height of the hill,

The maximum profit is given as $31,310

a. In order to determine the intervals in which profitability P increases and decreases, we need to analyze the first derivative of its respective function, P(x).

Given the profit equation: P(x) = 2.36x - (x^2 / 25000) - 3500, the process begins by articulating its derivative, P'(x):

P'(x) = d(2.36x) - d(x^2 / 25000) - d(3500)

P'(x) = 2.36 - (2x / 25000)

P'(x) = 2.36 - x / 12500

Seeing that P'(x) > 0 implies a rising P while P'(x) < 0 portrays a decreasing P, those values must be determined. Subsequently, the critical points may be found by setting P'(x) = 0:

2.36 - x / 12500 = 0

x / 12500 = 2.36

x = 2.36 * 12500

x = 29500

To adequately evaluate the intervals (0, 29500) and (29500, 50000), we must gauge whether P'(x) is positive or negative:

For x greater than zero & less than 29500:

P'(x) = 2.36 - x / 12500 > 0

For x higher than 29500 but falling beneath 50000:

P'(x) = 2.36 - x / 12500 < 0

Hence, P is augmented on the interval from 0 until 29500, whereas it diminishes from 29500 to 50000.

b. Differentiate again the profit function we get

P'(x)= -1/12,500 <0

Therefore the profit will be maximum.

Answer:

Step-by-step explanation:

This is a mathematical problem that involves exponential decay. To predict the number of African cheetahs living in the wild in 21 years, we need to use the formula:

N(t)=N0​×(1−r)t

where N(t) is the number of cheetahs after t years, N0​ is the initial number of cheetahs, and r is the annual rate of decline.

According to 1, scientists estimate that fewer than 8,000 African cheetahs are living in the wild today and that the population is expected to decline at a rate of 9.8% per year. Therefore, we can plug in these values into the formula:

N(21)=8000×(1−0.098)21

Using a calculator, we can simplify this expression to get:

N(21)≈8000×0.057≈456

Therefore, we can predict that there will be about 456 African cheetahs living in the wild in 21 years, if nothing changes.

This is a very alarming number and shows how endangered these animals are. We need to take urgent action to protect them and their habitats from threats such as habitat loss, human-wildlife conflict, and illegal trade.

Find the radius of the pool:

Since the diameter is 115 cm, the radius (r) will be half of that:

Radius (r) = Diameter / 2

r = 115 cm / 2

r = 57.5 cm

Calculate the volume of the pool when filled to a depth of 20 cm:

Since the pool is round and assuming it has a cylindrical shape, we can use the formula for the volume of a cylinder:

Volume = π × r² × h

where π (pi) is approximately 3.14159, r is the radius, and h is the height (or depth, in this case).

Volume = 3.14159 × (57.5 cm)² × 20 cm

Evaluate the volume:

Volume ≈ 3.14159 × 3306.25 cm² × 20 cm

Volume ≈ 3.14159 × 66125 cm³

Volume ≈ 207354.2 cm³

Calculate the time it takes to fill the pool to a depth of 20 cm:

We are given that the hose fills the pool at a rate of 34,000 cm³ per minute. To find out how long it will take to fill the pool, we can use the following formula:

It is essential to determine accuracy to ensure that the collected data is reliable and can be used to make informed decisions.

How to solve the question?

Data collection is an essential aspect of research and analysis, as it involves gathering information from various sources to make informed decisions. Inaccurate data can lead to incorrect conclusions and flawed decision-making, which can have significant consequences. Therefore, it is crucial to determine the accuracy of the collected data.

Accuracy can be determined in several ways. One way is by how close repeated measurements of an attribute are to each other. This method is known as precision. If repeated measurements are consistent with one another, it indicates that the data is precise. However, precision does not necessarily imply accuracy, as the measured values could be consistently wrong.

Another way to determine accuracy is by how close repeated measurements are to the true value of the attribute being measured. This method is known as validity. Validity ensures that the collected data accurately reflects the attribute being measured. This method is often used in experiments to test the effectiveness of a treatment or intervention. The results of an experiment are valid if they accurately reflect the effects of the treatment or intervention being tested.

Accuracy can also be determined by how much deviation there is between the measured values and the true value. This method is known as error. An error is the difference between the measured value and the true value. The smaller the error, the more accurate the data.

In conclusion, accuracy in data collection is determined by how close the measured values are to the true value, how close repeated measurements are to each other, and how much deviation there is between the measured values and the true value. It is essential to determine accuracy to ensure that the collected data is reliable and can be used to make informed decisions.

We need to check if either of these solutions is an extraneous solution, which means it does not satisfy the original equation.

Here given equation,

√(3x - 5) = x - 8

Here we want to isolate the square root on one side and square both sides.

Squaring both side,

√(3x - 5)² = (x - 8)²

expanding the right side

3x - 5 = x² - 16x + 64

bringing all terms to one side)

x² - 19x + 69 = 0

We are solving this quadratic equation using the quadratic formula,

x = [19 ± √(19²- 4(1)(69))] / (2(1))

x = [19 ± √(253)] / 2

x ≈ 1.535 or x ≈ 17.465

Now, we plug each solution back into the original equation and see if we get a true statement.

Checking x ≈ 1.535:

√(3(1.535) - 5) = 1.535 - 8

√(0.605) ≈ -6.465 (not true)

Checking x ≈ 17.465,

√(3(17.465) - 5) = 17.465 - 8
