what is the volume of a solid with a radius of 12 and a height of 24

The values of all the angles are shown:

(A) m∠1: 62°   (B) m∠2: 39°

(C) m∠3: 26°  (D) m∠4: 45°

(E) m∠5: 55°  (F) m∠6: 45°

Two rays that have a common terminal and are referred to as the angle's sides and vertices, respectively, make up an angle in Euclidean geometry.

Two rays can form angles in the plane where they are positioned.

Angles are also produced when two planes intersect.

These are what are known as dihedral angles.

So, the following values of the angles are:

(A) m∠1:

28 + 90 + ∠1 = 180

118 + ∠1 = 180

∠1 = 180 - 118

∠1 = 62°

(B) m∠2:

51 + 90 + ∠1 = 180

141 + ∠1 = 180

∠1 = 180 - 141

∠2 = 39°

(C) m∠3:

25 + (180-51) + ∠3 = 180

25 + 129 + ∠3 = 180

154 + ∠3 = 180

∠3 = 180 - 154

∠3 = 26°

(D) m∠4:

∠4 + ∠6 + 90 = 180

∠4 + ∠6 = 180 - 90

∠4 + ∠4 = 90 (∠4 and ∠6 are equal:  Isosceles triangle)

2∠4 = 90

∠4 = 90/2

∠4 = 45°

(E) m∠5:

35 + 90 + ∠5 = 180

125 + ∠5 = 180

∠5 = 180 - 125

∠5 = 55°

(F) m∠6:

∠4 = ∠6 = 45°

Therefore, the values of all the angles are shown:

(A) m∠1: 62°   (B) m∠2: 39°

(C) m∠3: 26°  (D) m∠4: 45°

(E) m∠5: 55°  (F) m∠6: 45°

Therefore , large of a sample would be required in order to estimate the mean per capita income will be $3,838.

You can assess the degree to which the distribution of your data conforms to that predicted underneath the null hypothesis of the statistical test you are just using by utilizing a test statistic. The data distribution, which is determined by the confidence interval and deviation from the central tendency of each observation, represents the frequency of each observation.

Here,

First step is to find z 80% confidence level

At 80% confidence level the z will be:

α/2 = 1 - 80% = 1 - 0.80 = 0.20

α/2= 0.20 / 2 = 0.01

Zα/2= Z0.01= 1.28 from z table

Now let calculate the Sample size using this formula

Sample size = n= [( Z[tex]\alpha[/tex]/2* σ ) / E]^2

Let plug in the formula

n = (1.28*12.1/0.25)^2

n= 3,838.05

As per the concept of compound interest, it take 62.915 years for the account to earn $7500

Compound interest:

The general formula to calculate the compound interest is written as,

A = P(1 + r/n)^nt

where

A = Accrued amount (principal + interest)

P = Principal amount

r = Annual nominal interest rate as a decimal

n = number of compounding periods per unit of time

t = time in decimal years;

Given,

Compounding frequency = Quarterly

Interest rate = 1.75%

Opening balance = $2500

Final amount = $7500

Now, we have to calculate the time time for the person to achieve the final amount,

First, convert R as a percent to r as a decimal

r = R/100

r = 1.75/100

r = 0.0175 per year,

Then, solve the equation for t

t = ln(A/P) / n[ln(1 + r/n)]

t = ln(7,500.00/2,500.00) / ( 4 × [ln(1 + 0.0175/4)] )

t = ln(7,500.00/2,500.00) / ( 4 × [ln(1 + 0.004375)] )

t = 62.915 years

Therefore, the  time required to get a total amount of $7,500.00 with compounded interest on a principal of $2,500.00 at an interest rate of 1.75% per year and compounded 4 times per year is 62.915 years.

Answer:

is there a graph available????

Step-by-step explanation:

The right response is (b), as it increases the minimum sample size required to ensure a given margin of error.

When a tiny sample of data from a relatively large population is estimated, this is what is meant by the term "margin of error" .  The standard deviation, sample size, and desired confidence level are often the factors that control the margin of error.

calculation

Let's take a look at the values in the supplied statement to discover the missing term.

the population's standard deviation is where

m stands for "Margin of Error," and Z stands for "Empirical Value of Z-Score" at a specific confidence level.

As a result, the recommended minimum sample size for a particular degree of confidence is

⇒ (Z×σ)²/m²

The minimal sample size is directly correlated with the population's standard deviation, as shown by the calculation above.

Therefore, when the population "standard deviation" increased, the minimal sample size needed would also "rise."

Answer:

There is no solution to this problem. It is not possible to find three numbers that form an arithmetic sequence and, when 1, 3, and 9 are added to them respectively, form a geometric sequence.

Step-by-step explanation:

To find the three numbers in the arithmetic sequence, let's call the first number in the sequence "a," the second number "a + d," and the third number "a + 2d," where "d" is the common difference between the numbers. The sum of these three numbers is:

a + (a + d) + (a + 2d) = 15

This simplifies to:

3a + 3d = 15

To find the three numbers in the geometric sequence, let's call the first number in the sequence "b," the second number "r * b," and the third number "r^2 * b," where "r" is the common ratio between the numbers. The sum of these three numbers is:

b + (r * b) + (r^2 * b) = 15 + b + (r * b) + (r^2 * b)

This simplifies to:

b(1 + r + r^2) = 15 + b + br + br^2

We are told that if 1, 3, and 9 are added to the three numbers in the arithmetic sequence, we get the three numbers in the geometric sequence. Therefore, we can set up the following system of equations:

3a + 3d = 15

b(1 + r + r^2) = 15 + b + br + br^2

Subtracting b from both sides of the second equation gives:

b(1 + r + r^2) - b = 15 + br + br^2

This simplifies to:

b(r^2 + r - 1) = 15 + br + br^2

Subtracting br and br^2 from both sides gives:

b(r^2 + r - 1) - br - br^2 = 15

This simplifies to:

b(r^2 + r - 1 - r - r^2) = 15

This simplifies to:

b(r - 1)(r + 1) = 15

Dividing both sides by (r - 1)(r + 1) gives:

b = 15 / (r - 1)(r + 1)

We are told that the three numbers in the arithmetic sequence add up to 15, so we can substitute 3a + 3d = 15 into the equation above to solve for "b":

3a + 3d = 15

b = 15 / (r - 1)(r + 1)

Substituting 3a + 3d = 15 into the equation above gives:

b = 15 / (r - 1)(r + 1)

Substituting b = 15 / (r - 1)(r + 1) into the second equation gives:

15 / (r - 1)(r + 1)(1 + r + r^2) = 15 + 15 / (r - 1)(r + 1) + 15 / (r - 1)(r + 1)*r + 15 / (r - 1)(r + 1)*r^2

This simplifies to:

15 / (r - 1)(r + 1)(1 + r + r^2) = 15 + 15r + 15r^2

Multiplying both sides by (r - 1)(r + 1) gives:

15 = 15 + 15r + 15r^2

Subtracting 15 from both sides gives:

0 = 15r + 15r^2

Subtracting 15r^2 from both sides gives:

0 - 15r^2 = 15r

This simplifies to:

-15r^2 = 15r

Dividing both sides by -15 gives:

r^2 = r

Solving for "r" gives:

r = 1 or r = 0

If "r" is equal to 1, then the common ratio between the numbers in the geometric sequence is 1, which means that the three numbers in the geometric sequence are the same. This does not satisfy the condition that the three numbers in the geometric sequence are formed by adding 1, 3, and 9 to the three numbers in the arithmetic sequence, so we can eliminate this solution.

If "r" is equal to 0, then the common ratio between the numbers in the geometric sequence is 0, which means that the three numbers in the geometric sequence are all 0. This does not satisfy the condition that the three numbers in the geometric sequence are formed by adding 1, 3, and 9 to the three numbers in the arithmetic sequence, so we can eliminate this solution as well.

Therefore, there is no solution to this problem. It is not possible to find three numbers that form an arithmetic sequence and, when 1, 3, and 9 are added to them respectively, form a geometric sequence.

The speed of a cyclist rode 3.75 miles in 0.3 hours is 0.36 hours.

Given that, a cyclist rode 3.75 miles in 0.3 hours.

The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.

A) We know that, speed =Distance/Time

Now, speed =3.75/0.3

= 12.5 miles per hour

B) Here, distance =4.5 miles and rate =12.5 miles per hour

Now, 12.5 =4.5/Time

⇒ Time =4.5/12.5
