1. The perimeter is 41.16 cm

2. The perimeter is 165.7 cm

Perimeter is a term used in geometry to describe the total length of the boundary or the distance around the edge of a two-dimensional shape.

1. Here, radius = 4cm,

Circumference of quarter circle = [tex]\frac{1}{4}[/tex] ×2πr = [tex]\frac{1}{4}[/tex] ×2×3.14×4 = 6.29 cm

Circumference of four quarters circle= 4×6.29 = 25.16 cm,

The dimension of cone B is r = 4 and h = 9. Because the volume formula for a cone only considers the radius and height of the cone and not orientation, we know that cones B and A have the same volume.

The area that any three-dimensional solid occupies is known as its volume. These solids can take the form of a cube, cuboid, cone, cylinder, or sphere.

Many forms have various volumes. In 3D geometry, we have examined the numerous forms and solids such as cubes, cuboids, cylinders, cones, etc., that are specified in three dimensions. We will discover how to find the volume for each of these forms.

The volume of the cone is given by:

Volume = (1/3)πr²h

For cone B:

48π = (1/3)πr² * h

144 = r² * h

Suppose the r = 4 and h = 9:

144 = 4² * 9

144 = 144

True.

The possible dimension of cone B is r = 4 and h = 9.

Because the volume formula for a cone only considers the radius and height of the cone and not its shape or orientation, we know that cones B and A have the same volume. We utilised this rule to get the potential values for cone B: any two cones with the same volume must have the same product of radius and height.

Answer:

each term is half the previous one. 1.6 *.5^(n-1). is a geometric sequence.

This is a geometric sequence with a common ratio of 1/2. Therefore, option B is correct.

A geometric sequence is a sequence of numbers where each term is found by multiplying the previous term by a fixed constant called the common ratio (r).

In other words, if the first term of the sequence is "a", then the nth term of the sequence is given by:

an = a * r^(n-1)

where "n" is the position of the term in the sequence.

In this question:

To see why, notice that each term is half of the previous term:

0.8 is half of 1.6

0.4 is half of 0.8

0.2 is half of 0.4

In a geometric sequence, each term is obtained by multiplying the previous term by a fixed constant, which is called the common ratio. In this case, the common ratio is 1/2, because each term is half of the previous term.

So the sequence can be written as:

1.6, 0.8, 0.4, 0.2, …

To multiply 9200 and 2.3 x 10^3 in scientific notation, we need to multiply their coefficients and add their exponents.

9200 x 2.3 x 10^3 = 21,160,000

Since the product is greater than 10, we need to adjust the coefficient and the exponent to express the number in scientific notation. We can move the decimal point to the left until there is only one digit to the left of the decimal point, and count how many places we moved the decimal point. In this case, we need to move the decimal point 7 places to the left:

2.116 x 10^7

Therefore, the product of 9200 and 2.3 x 10^3 expressed in scientific notation is 2.116 x 10^7.

Rounding to the nearest inch, the length of side W (w) is approximately 588 inches.

Here, we have,

To find the length of side W (w) in triangle WXY, we can use the Law of Sines, which states:

a/sin(A) = b/sin(B) = c/sin(C)

where:

a, b, c are the side lengths of the triangle.

A, B, C are the opposite angles to sides a, b, c, respectively.

In this case, we have:

Side XY = y = 940 inches

Angle Y = ∠Y = 100°

Angle W = ∠W = 38°

We want to find the length of side W (w).

Using the Law of Sines:

w/sin(∠W) = y/sin(∠Y)

Now, substitute the given values:

w/sin(38°) = 940/sin(100°)

Now, solve for w:

w = (940 * sin(38°)) / sin(100°)

Using a calculator:

w ≈ (940 * 0.6157) / 0.9848

w ≈ 588.388

Let's first calculate the probability of getting the question right if you eliminate one of the six choices. Since there are six options, initially you have a 1/6 chance of getting the question right. If you eliminate one of the options, you are left with five choices, so your probability of getting the question right increases to 1/5.

Now, let's calculate the expected value of the number of points you get. If you get the question right, you earn one point. If you get the question wrong, you lose 1/3 point. So, we can write the expected value as:

Expected value = Probability of getting the question right x Points for a correct answer + Probability of getting the question wrong x Points for a wrong answer

Let's plug in the values:

Expected value = (1/5) x 1 + (4/5) x (-1/3)

Expected value = 1/5 - 4/15

Expected value = -1/15

So, the expected value of the number of points you get is -1/15. This means that, on average, you can expect to lose about 0.067 points for each question you attempt.

Complete Question:

The sampling distribution of the proportion of people who respond "yes" in samples of 4 individuals is not binomial. This is because the binomial distribution has specific requirements that must be met, including a fixed number of trials, independent outcomes, and a constant probability of success. the probability of observing a sample proportion of 0.75 or higher is approximately 0.16.        

Assuming that the sample size is sufficiently large and the proportion of people who respond "yes" in the population is not too close to 0 or 1, the sampling distribution of the proportion of people who respond "yes" in samples of 4 individuals can be approximated by a normal distribution using the Central Limit Theorem. This means that the distribution of the sample proportion will be approximately normal with a mean equal to the population proportion and a standard deviation equal to the square root of [p(1-p)/n], where p is the population proportion and n is the sample size.

For example, let's say that we know that 60% of the population believes that gun laws should be more stringent. If we take samples of 4 individuals and calculate the proportion of people who respond "yes" in each sample, the sampling distribution of these proportions can be approximated by a normal distribution with a mean of 0.6 and a standard deviation of sqrt[(0.6)(0.4)/4] = 0.15.

Using this normal approximation, we can calculate probabilities and confidence intervals for the sample proportion. For example, if we take a sample of 4 individuals and find that 3 of them respond "yes," the sample proportion is 0.75. We can calculate the probability of observing a sample proportion of 0.75 or higher by standardizing the sample proportion using the mean and standard deviation of the sampling distribution:

z = (0.75 - 0.6)/0.15 = 1

Using a standard normal distribution table or calculator, we can find that the probability of observing a standard normal random variable greater than or equal to 1 is approximately 0.16. This means that the probability of observing a sample proportion of 0.75 or higher is approximately 0.16.

In summary, while the sampling distribution of the proportion of people who respond "yes" in samples of 4 individuals is not binomial, it can be approximated by a normal distribution using the Central Limit Theorem under certain conditions. This approximation allows us to calculate probabilities and confidence intervals for the sample proportion, even when the exact distribution is unknown.
