Volume of the sphere is equal to two-third of the volume of a cylinder.

Volume is a mathematical concept that refers to the amount of space occupied by a three-dimensional object. It is expressed in cubic units, such as cubic meters or cubic centimeters, and can be calculated using a specific formula for each type of geometric shape.

A sphere is a perfectly round, three-dimensional object that looks like a ball. It has no edges or vertices and is symmetric around its center point. The formula for calculating the volume of a sphere is V = 4/3 πr³, where V is the volume, π is a mathematical constant approximately equal to 3.14, and r is the radius of the sphere.

True.

Assume that both the sphere's and cylinder's radius is r.

Considering that the base's diameter equals the cylinder's height

⇒h = 2r

Sphere radius = cylinder radius = r

Assuming the conditions are met, the sphere's volume:

=  [tex]\frac{2}{3}[/tex] × Volume of cylinder

= [tex]\frac{4}{3}[/tex]πr³= [tex]\frac{2}{3}[/tex] × πr² × 2r

=[tex]\frac{4}{3}[/tex]πr³= [tex]\frac{4}{3}[/tex]πr³

Hence, volume of the sphere is equal to two-third of the volume of a cylinder.

The approximate standard error of the mean is 3.

Here is how to find the approximate standard error of the mean from a population of 600 elements, where a sample of 100 elements is selected, and it is known that the variance of the population is 900.

Determine the sample size n, which is 100

Find the population variance, which is 900.

Compute the population standard deviation, which is the square root of the variance, as follows:

σ = √900σ

= 30

Compute the standard error of the mean as follows:

SEM = σ/√nSEM

= 30/√100SEM

= 3

The standard error of the mean (SEM) can be calculated using the formula:

SEM = σ / √n
where σ represents the population standard deviation, and n represents the sample size. In this case, we know that the population variance is 900.

To find the standard deviation, take the square root of the variance:
σ = √900 = 30
Now, we can plug in the values into the formula:
SEM = 30 / √100
SEM = 30 / 10
SEM = 3
The approximate standard error of the mean for this sample is 3.

Answer:

the amount at the end of the third year is A3 = $11,330.40.

Step-by-step explanation:

To solve this problem, we can use the formula for compound interest:

A = P(1 + r/n)^(n*t)

Where:

A = the final amount

P = the principal (initial amount)

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the number of years

For the first year, the interest rate is 10%, so we have:

A1 = 8000(1 + 0.1/1)^(1*1)

A1 = 8800

After the first year, the principal becomes 8800. For the second year, the interest rate is 12%, so we have:

A2 = 8800(1 + 0.12/1)^(1*1)

A2 = 9856

After the second year, the principal becomes 9856. For the third year, the interest rate is 15%, so we have:

A3 = 9856(1 + 0.15/1)^(1*1)

A3 = 11330.4

Therefore, the amount at the end of the third year is A3 = $11,330.40.

In summary, the initial amount of $8,000 is compounded annually for three years at different interest rates. By using the formula for compound interest, we find that the amount at the end of the third year is $11,330.40.

The amount of work required to stretch the spring from 30.0 cm to 36.0 cm is 1.411 joules, which can be rounded to three decimal places.

According to Hooke's Law, the amount of work required to stretch or compress a spring by a certain amount is given by the formula:

W = (1/2) k (x2 - x1)²

where W is the work done (in joules), k is the spring constant (in newtons per meter), x1 is the initial displacement (in meters), and x2 is the final displacement (in meters).

In this case, the spring has a natural length of 30.0 cm, which is equivalent to 0.3 meters. To find the spring constant, we can use the fact that a 20.0-N force is required to keep it stretched to a length of 42.0 cm, which is equivalent to 0.42 meters.

Using Hooke's Law, we have

F = k (x2 - x1)20.0 N

= k (0.42 - 0.3) m

=> k = 80.0 N/m

Now we can use Hooke's Law again to find the amount of work required to stretch the spring from 30.0 cm to 36.0 cm, which is equivalent to 0.36 meters.

Using Hooke's Law, we have:

F = k (x2 - x1)W

= (1/2) k (x2 - x1)²W

= (1/2) (80.0 N/m) (0.36 - 0.3) m²W

= 1.411 J

For a 95% confidence interval [22.10, 23.70].

For a 99% confidence interval [21.97, 23.83].

b) For a 90% confidence interval [22.25, 23.55].

a) To construct a confidence interval for the population mean age, we can use the formula: CI = x* ± tα/2 * (σ / sqrt(n)), where x* is the sample mean age, σ is the population standard deviation, n is the sample size, and tα/2 is the critical value of the t-distribution with n-1 degrees of freedom and a given level of confidence α/2.

For a 90% confidence interval, α = 0.1 and tα/2 = 1.725, so the interval is: 22.9 ± 1.725 * (1.5 / sqrt(20)) = [22.25, 23.55].

For a 95% confidence interval, α = 0.05 and tα/2 = 2.093, so the interval is: 22.9 ± 2.093 * (1.5 / sqrt(20)) = [22.10, 23.70].

For a 99% confidence interval, α = 0.01 and tα/2 = 2.861, so the interval is: 22.9 ± 2.861 * (1.5 / sqrt(20)) = [21.97, 23.83].

b) If the given standard deviation of 1.5 years came from the sample instead of the population, we need to use a t-distribution with n-1 degrees of freedom to construct the interval. The formula is the same as before, but we replace σ with s, the sample standard deviation.

For a 90% confidence interval, the critical value is still 1.725, so the interval is: 22.9 ± 1.725 * (1.5 / sqrt(20)) = [22.25, 23.55].

c) If the distribution of the population is not specified, we can still form a confidence interval if we have a large enough sample size (typically, n >= 30) due to the central limit theorem. In this case, we have n = 20, so we may not have enough information to form a confidence interval if we cannot assume the population is normally distributed.

To take a systematic sample of 100 companies from the 1,803 companies that are members of an industry trade association, follow these steps

Determine the sampling interval (k), which is the number of companies in the population divided by the desired sample size. In this case, k = 1803/100 = 18.03. Round this number up or down to the nearest whole number based on your sampling preferences.

Choose a random starting point between 1 and k. For example, you could randomly select a number between 1 and 18.

From the starting point, select every kth company in the list of members until you have 100 companies. For example, if the starting point is 4, you would select companies 4, 22, 40, 58, 76, 94, 112, and so on until you reach 100 companies.

The minimum cost occurs when Jay plants 30 tulip bulbs and 15 lily bulbs, and the minimum cost is $67.50.

Let x be the number of tulip bulbs that Jay plants, and let y be the number of lily bulbs that Jay plants.

Since Jay wants to plant at least twice as many tulips as lilies, we have the constraint:

x ≥ 2y

Also, the total number of bulbs that Jay plants cannot exceed 60, so we have the constraint:

x + y ≤ 60

We want to minimize the total cost of the bulbs that Jay purchases, which is given by the object function:

C = 1.6x + 1.25y

To solve this problem, we can use linear programming. First, we graph the two constraints on a coordinate plane:

The shaded region represents the feasible region, which is the region that satisfies both constraints. The vertices of the feasible region are (0, 0), (40, 20), (60, 0), and (30, 15).

Next, we evaluate the object function at each vertex to find the minimum value. We have:

C(0, 0) = 0

C(40, 20) = 1.6(40) + 1.25(20) = 92

C(60, 0) = 1.6(60) + 1.25(0) = 96

C(30, 15) = 1.6(30) + 1.25(15) = 67.5

Therefore, the minimum cost occurs when Jay plants 30 tulip bulbs and 15 lily bulbs, and the minimum cost is $67.50.

Graphically, we can see that the optimal solution occurs at the intersection of the two constraints, which is the point (30, 15). This is where the slope of the object function is equal to the slope of the feasible region, which indicates that the object function is optimized at this point.

The average speed of the round-trip for same path back to his house is given by 3 miles per hour.

The mean value of a body's speed over a period of time is its average speed. As a moving body's speed is not constant over time and fluctuates, the average speed formula is required. The values of total time and total distance travelled may be employed even when the speed varies, and with the aid of the average speed formula, we can identify a single number that sums up the whole motion.

So the average speed is simply: [tex]\frac{distance}{time}[/tex]

In case, the total time = 25 minutes + 55 minutes

which is a total of 80 minutes, or 1.33 hours.

The total distance traveled is two miles + two miles, since he jogged two miles to the park, and then he turns around and walks the same path.

So in total he traveled 4 miles.

Plugging this in to the formula gives you the equation:

The solutions to the equation are x = -11/3 and x = 6.

In mathematics, an equation is a statement that two expressions are equal. It consists of two sides separated by an equal sign (=). The expression on the left side of the equal sign is usually called the left-hand side (LHS), while the expression on the right side is called the right-hand side (RHS).

Equations can take many different forms and can involve various types of functions and operators, such as addition, subtraction, multiplication, division, exponentiation, logarithms, trigonometric functions, and more. They can also involve one or more variables, which can be solved for to obtain a specific value or range of values that make the equation true. Equations are used extensively in mathematics, science, engineering, economics, and many other fields.

To solve the equation for x, we can start by simplifying both sides of the equation and bringing all the terms to one side:

(1)/(x²-6x) - (x)/(x²-36) = 2

We can simplify the left side of the equation by finding a common denominator:

[(1)(x-6) - (x)(x+6)] / [(x-6)(x+6)] = 2

Expanding the numerator and simplifying, we get:

(-x² + 7x - 6) / [(x-6)(x+6)] = 2

Multiplying both sides by the denominator, we get:

-x² + 7x - 6 = 2(x-6)(x+6)

Expanding the right side, we get:

-x² + 7x - 6 = 2(x² - 36)

Simplifying and rearranging, we get:

3x² - 7x - 66 = 0

We can solve this quadratic equation by factoring or using the quadratic formula:

3x² - 7x - 66 = (3x + 11)(x - 6) = 0

So either 3x + 11 = 0 or x - 6 = 0:

3x + 11 = 0 => x = -11/3

x - 6 = 0 => x = 6

Therefore, the solutions to the equation are x = -11/3 and x = 6.

For the given triangle, m∠CBD = 63 degrees.

What is triangle?

A triangle is a two-dimensional geometric shape with three sides and three angles. It is one of the basic shapes in geometry and is formed by connecting three non-collinear points with line segments.

In a triangle, the sum of the angles is always 180 degrees.

So, we can write:

m∠ABD = m∠ABC + m∠CBD

Substituting the given values, we get:

96 = (7x - 9) + (6x + 27)

Simplifying the equation:

96 = 13x + 18

Subtracting 18 from both sides:

78 = 13x

Dividing by 13:

x = 6

Therefore:

m∠ABD = 96 degrees
