The perimeter of a square is 52cm.
Calculate the area

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,

and 4 extra portion 4×4 = 16 cm

So, the Perimeter = 25.16 + 16 = 41.16 cm

2. The diameter = 40 cm then, Radius= 20 cm

here, 2 quarter circle and 1 half circle is equal to 1 complete circle.

Then circumference of circle equal to 2π r = 2×3.14×20 = 125.71,

So the perimeter = 125.71 + 20 + 20 = 165.7 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, …

or

a₁, a₁/2, a₁/4, a₁/8, …

where a₁ is the first term, which is 1.6 in this case.

The total space that the cargo will take up is 7 x 10⁷ cubic feet.

In geometry, a prism is a three-dimensional solid shape that consists of two congruent bases (which can be any polygon) and a set of parallel line segments that connect the corresponding vertices of the two bases. The bases are usually parallel and of the same shape and size, and the line segments connecting the vertices are known as the lateral faces of the prism.

Prisms are commonly found in architecture and engineering, where they are used to create structures such as buildings, bridges, and towers. They are also used in optics, where they are used to refract and reflect light, and in mathematics, where they are used to study geometric properties and relationships.

To find the total space that the energy prisms will take up, we need to multiply the number of prisms by the amount of space each prism takes up. We can use scientific notation to simplify the calculation:

3.5 x 10⁵ energy prisms * 2 x 10² cubic feet per prism

The probability that Ben will make three out of his next five free throws is approximately 0.3456

Assuming that each free throw attempt is independent of the others, we can use the binomial distribution to calculate the probability of Ben making three out of his next five free throws.

The probability of making a free throw is 0.6, so the probability of missing a free throw is 0.4. Let X be the number of successful free throws out of 5 attempts. Then X follows a binomial distribution with n = 5 and p = 0.6.

The probability of making three out of five free throws can be calculated as follows

P(X = 3) = (5 choose 3) × (0.6)^3 × (0.4)^2

where (5 choose 3) = 10 is the number of ways to choose 3 successful free throws out of 5 attempts.

If the money box has 600 coins that consist of 20 cents and 50 cents, the total amount of cents in the money box is 24,000 cents.

To determine the total amount of cents in Thabang's money box, we need to know how many of the 600 coins are 20 cents and how many are 50 cents. Let's use variables to represent these quantities.

Let x be the number of 20 cent coins, and y be the number of 50 cent coins. We know that the total number of coins is 600, so we have:

x + y = 600

We also know that the value of each 20 cent coin is 20 cents, and the value of each 50 cent coin is 50 cents. So the total value of the coins in the money box is:

20x + 50y

To find the total amount of cents in the money box, we need to simplify and solve for the value of the expression above. We can do this by using the equation we have for x and y and substituting y = 600 - x:

20x + 50(600 - x) = 20x + 30000 - 50x = -30x + 30000

So the total value of the coins in the money box is -30x + 30000 cents. We don't know the value of x yet, but we know that x and y must be non-negative integers and x + y = 600.

We can solve for x by trying different values of x until we find one that satisfies these conditions. For example, if we set x = 200, then y = 400 and the conditions are satisfied. Therefore, the total amount of cents in the money box is:

-30x + 30000 = -30(200) + 30000 = 24000

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.

If the population density for the area is 18.8 residents per square mile, to the nearest hundred, approximately 34,000 residents would be infected.

When a virus is accidentally released from a CDC lab, and it infects everyone within a 24-mile radius from the CDC lab, then if the population density for the area is 18.8 residents per square mile, to the nearest hundred, how many people were infected.

The number of people infected within the 24-mile radius from the CDC lab is calculated as follows:

The area of a circle with a radius of 24 miles is A = πr²,

which is A = π(24²) = 1,809.56 square miles, and the population density for the area is 18.8 residents per square mile.

Therefore, the number of people infected is calculated by multiplying the area by the population density:

Residents infected = area x population density
