To find the approximate population of China, we need to multiply the population of Vatican City by 1.75 × 106:

Population of China = Population of Vatican City × 1.75 × 106

Population of China = 800 × 1.75 × 106

Population of China = 1.4 × 109

Therefore, the approximate population of China is 1.4 × 109, which is option D.

Trigonometry is a branch of mathematics that deals with the relationships between the sides and angles of triangles. It involves the study of trigonometric functions such as sine, cosine, and tangent, which are used to relate the angles of a triangle to the lengths of its sides. Trigonometry has a wide range of applications in fields such as physics, engineering, navigation, surveying, and astronomy. For example, trigonometry is used in navigation to calculate the angles between a ship and a lighthouse, or between two ships, in order to determine their relative positions. In engineering, trigonometry is used to calculate the forces acting on structures such as bridges and buildings, and to design and build machines that rely on the principles of motion and energy.

Here,

For the first triangle, we have:

Using the sine ratio,

sin(36) = x / 9

Solving for x, we get:

x = 9 sin(36)

≈ 5.4

Rounding to the nearest tenth, we get:

x ≈ 5.4

For the second triangle, we have:

Using the tangent ratio,

tan(27) = x / 21

Solving for x, we get:

x = 21 tan(27)

≈ 11.1

Rounding to the nearest tenth, we get:

x ≈ 11.1

The probability that at most 13 of the residers in the sample entered a jury process in the once 12 months is 0.000158.

A normal distribution, also known as a Gaussian distribution or bell wind, is a probability distribution that's symmetric and bell- shaped. It's characterized by its mean( μ) and standard divagation( σ).

Given

Sample size( n) = 500

Probability of an individual entering a jury process( p) = 15 = 0.15

We want to calculate the probability that at most 13 of the residers in the sample entered a jury process.

Let X be the arbitrary variable representing the number of residers who entered a jury process in the sample.

Using the binomial accretive distribution function( CDF), we can calculate the probability as follows

P( X ≤ 13 of n) = Σ( k = 0 to k = 0.13 n)( n C k)

Here, n = 500

p = 0.15

k = int(0.13 n)

So, binom.cdf( int(0.13 500), 500,0.15) ≈0.000158

Thus, The likelihood that 13% of the sample's residents received a jury summons in the previous year is 0.000158.

By using the cosines law we can say that, Velma and Fred are approximately 17.39 meters apart.

What is law of cosine?

The Law of Cosines is a formula used in trigonometry to relate the sides and angles of a triangle. It states that for any triangle with sides a, b, and c and angles A, B, and C opposite those sides, the following equation holds:

[tex]$c^2 = a^2 + b^2 - 2ab \cos(C)$[/tex]

where c is the side opposite angle C.

We can solve this problem using the law of cosines. Let's call the distance between Velma and Fred "[tex]$d$[/tex]". Then, we have:

[tex]$c^2 = a^2 + b^2 - 2ab \cos(C)$[/tex]

where [tex]$c$[/tex] is the distance between Velma and Fred (which we want to find), [tex]$a$[/tex] is the distance between Shaggy and Velma (which is 20 meters), [tex]$b$[/tex] is the distance between Shaggy and Fred, and [tex]$C$[/tex] is the angle formed at Shaggy (which is 30 degrees).

We can rearrange this equation to solve for [tex]$d$[/tex]:

[tex]$d^2 = a^2 + b^2 - 2ab \cos(C)$[/tex]

[tex]$d^2 = 20^2 + b^2 - 2(20)(b) \cos(30)$[/tex]

[tex]$d^2 = 400 + b^2 - 20b \sqrt{3}$[/tex]

We also know that the angle formed at Fred is 105 degrees, which means that the angle formed at Velma is 45 degrees (since the angles in a triangle sum to 180 degrees). This means that we can use the law of sines to find the value of [tex]$b$[/tex]:

[tex]$\dfrac{b}{\sin(B)} = \dfrac{a}{\sin(A)}$[/tex]

[tex]$\dfrac{b}{\sin(105)} = \dfrac{20}{\sin(45)}$[/tex]

[tex]$b = 20 \dfrac{\sin(105)}{\sin(45)}$[/tex]

[tex]$b \approx 27.68$[/tex]

Now we can substitute this value of [tex]$b$[/tex] into the equation we derived earlier to find [tex]$d$[/tex]:

[tex]$d^2 = 400 + (27.68)^2 - 20(27.68)\sqrt{3}$[/tex]

[tex]$d \approx 17.39$[/tex]

To solve this system of equations using the elimination method, we need to eliminate one of the variables. One way to do this is to add the two equations together in a way that will eliminate one of the variables.

First, we can multiply the second equation by -1 to change the sign of all its terms:

-6x + 5y = 1

-6x - 4y = 10

Now we can add the two equations together to eliminate x:

( -6x + 5y ) + ( -6x - 4y ) = 1 + 10

Simplifying the left side and the right side:

-12x + y = 11

Now we have one equation with one variable, y. We can solve for y by isolating it on one side of the equation:

-12x + y = 11

y = 12x + 11

We can substitute this expression for y into either of the original equations to solve for x. Let's use the first equation:

-6x + 5y = 1

-6x + 5(12x + 11) = 1

Simplifying the left side:

54x + 55 = 1

Subtracting 55 from both sides:

54x = -54

Dividing both sides by 54:

x = -1

So the solution to the system of equations is x = -1 and y = 1. We can check this solution by substituting these values into both original equations and verifying that they are true.

The value of M - N is [tex]8x^2[/tex] + 11x - 9 by subtracting the value of N from the value of M.

To find the value of M - N, we first need to subtract the second polynomial N from the first polynomial M.

M - N = ([tex]5x^2[/tex] + 7x - 4) - ([tex]-3x^2[/tex] - 4x + 5)

To subtract the polynomials, we need to add the opposite of the second polynomial (i.e., add the negative of N) to the first polynomial M:

M - N = [tex]5x^2[/tex] + 7x - 4 + [tex]3x^2[/tex] + 4x - 5

Now we can combine like terms:

M - N = ([tex]5x^2 + 3x^2[/tex]) + (7x + 4x) + (-4 - 5)

M - N = [tex]8x^2[/tex] + 11x - 9

Therefore, the value of M - N is [tex]8x^2[/tex] + 11x - 9.

In summary, we found the value of M - N by subtracting the polynomial N from the polynomial M and then combining like terms. The resulting polynomial is [tex]8x^2[/tex] + 11x - 9.

The exact prοbability οf there being exactly 70 accidents at the intersectiοn in οne year is apprοximately 0.00382.

Prοbability can be defined as ratiο οf number οf favοurable οutcοmes and tοtal number οutcοmes.

(a) Tο find the exact prοbability that there wοuld be exactly 70 accidents at the intersectiοn in οne year, we can use the Pοissοn distributiοn fοrmula:

P(X = k) =( [tex]e^{(-λ)[/tex] * [tex]λ^k[/tex]) / k!

where X is the number of accidents, λ is the average rate of accidents per week (1.4), and k is the number of accidents we're interested in (70).

To find the probability of 70 accidents in one year, we need to adjust the value of λ to reflect the rate over a full year instead of just one week. Since there are 52 weeks in a year, the rate of accidents over a year would be 52 * λ = 72.8.

So, we have:

P(X = 70) = ([tex]e^{(-72.8)[/tex]* [tex]72.8^(70)[/tex]) / 70!

Using a calculatοr οr sοftware, we can evaluate this expressiοn and find that:

P(X = 70) ≈ 0.00382

Therefοre, the exact prοbability οf there being exactly 70 accidents at the intersectiοn in οne year is apprοximately 0.00382.

(b) Tο use the nοrmal distributiοn as an apprοximatiοn, we need tο assume that the Pοissοn distributiοn can be apprοximated by a nοrmal distributiοn with the same mean and variance. Fοr a Pοissοn distributiοn, the mean and variance are bοth equal tο λ, sο we have:

mean = λ = 1.4

variance = λ = 1.4

Tο use the nοrmal apprοximatiοn, we need tο standardize the Pοissοn randοm variable X by subtracting the mean and dividing by the square rοοt οf the variance:

[tex]Z = (X - mean) / \sqrt{(variance)[/tex]

Fοr X = 70, we have:

Z = (70 - 1.4) / [tex]\sqrt{(1.4)[/tex] ≈ 57.09

We can then use a standard nοrmal table οr calculatοr tο find the prοbability that a standard nοrmal randοm variable is greater than οr equal tο 57.09. This prοbability is extremely small and practically 0, indicating that the nοrmal apprοximatiοn is nοt very accurate fοr this particular case.

The approximation using the normal distribution gives a probability of approximately 0.3300 that there would be exactly 70 accidents at this intersection in one year.

what is probability?

Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 means the event is impossible and 1 means the event is certain to happen.

(a) Using the Poisson distribution, the probability of exactly 70 accidents at this intersection in one year (i.e., 52 weeks) is:

P(X = 70) = (e^(-λ) * λ^x) / x!

where λ = average rate of accidents per week = 1.4

and x = number of accidents in 52 weeks = 70

Therefore, P(X = 70) = (e^(-1.4) * 1.4^70) / 70! ≈ 3.33 x 10^-23

(b) We can use the normal approximation to the Poisson distribution to approximate the probability that there would be exactly 70 accidents at this intersection in one year. The mean of the Poisson distribution is λ = 1.4 accidents per week, and the variance is also λ, so the standard deviation is √λ.

To use the normal distribution approximation, we need to standardize the Poisson distribution by subtracting the mean and dividing by the standard deviation:

z = (x - μ) / σ

where x = 70, μ = 1.452 = 72.8, σ = √(1.452) ≈ 6.37

Now we can use the standard normal distribution table to find the probability that z is less than or equal to a certain value, which corresponds to the probability that there would be exactly 70 accidents at this intersection in one year:

P(X = 70) ≈ P((X-μ)/σ ≤ (70-72.8)/6.37)

≈ P(Z ≤ -0.44)

≈ 0.3300

Therefore, the approximation using the normal distribution gives a probability of approximately 0.3300 that there would be exactly 70 accidents at this intersection in one year.

30% of r = 33

Find 1% by taking

33 / 30 = 1.1

What is 70% of R?

We take

1.1 x 70 = 77

So, 70% of R is 77

The question requires to first find the value of R by solving the equation (0.30*R = 33). Then, calculate 70% of R by multiplying the found R value with 0.70.

The question tells us that 30% of R equals 33. To find the value of R, we can set up an equation where 0.30 (which is 30% in decimal form) times R equals 33. Dividing both sides of the equation by 0.30 will give us the value for R. Once we have found R, we can then find 70% of R by multiplying R by 0.70 (70% in decimal form).

  428.75π ft³

Step-by-step explanation:

You want the exact volume of a cylinder 35 ft high with a radius of 3.5 ft.

The volume is given by the formula ...

  V = πr²h

  V = π(3.5 ft)²(35 ft) = 428.75π ft³ . . . . . use the given values

The exact volume of the cylinder is 428.75π ft³.

The distance of the fire from the road is d ≈ 6.15 miles + 2.94 miles ≈ 9.09 miles.

The two expressions for d give slightly different values. This is due to the fact that we rounded the values of x and y in our calculations.

In problem 9, we can use trigonometry to find the distance, d, of the fire from the road. Let x be the distance from Star Point Ranger Station to the fire, and let y be the distance from Twin Pines Ranger Station to the fire. Then, we have:

tan(34°) = d/x

tan(14°) = d/y

Multiplying both sides of each equation by the respective denominator and simplifying, we get:

d = x tan(34°)

d = y tan(14°)

Since the two expressions for d are both equal, we can set them equal to each other and solve for x and y:

x tan(34°) = y tan(14°)

x = (y tan(14°))/tan(34°)

Substituting the value we found for y in problem 7, which was y = 6.15 miles, we get:

x = (6.15 miles) * tan(14°) / tan(34°) ≈ 2.94 miles

Therefore, the distance of the fire from the road is d ≈ 6.15 miles + 2.94 miles ≈ 9.09 miles.

Now, let's check our answers using both expressions for d:

d = x tan(34°) ≈ 2.94 miles * tan(34°) ≈ 2.94 miles * 0.704 = 2.07 miles

d = y tan(14°) ≈ 6.15 miles * tan(14°) ≈ 6.15 miles * 0.249 = 1.53 miles

As we can see, the two expressions for d give slightly different values. This is due to the fact that we rounded the values of x and y in our calculations. If we use the exact values, we would get slightly different values for d, but they would still be very close.

In real life, it is important to be as accurate as possible when dealing with emergencies such as fires. However, in this case, the difference between the two values of d is relatively small, so it may not have a significant impact on the response to the fire. Nevertheless, it is important to use the most accurate values possible to ensure the safety of those involved.
