The mean of the sample is 5, 3, 5, 12, 3, 2 the coefficient of variation is 91%. Option A is the correct answer.

To calculate the coefficient of variation, first, we need to calculate the standard deviation and mean of the sample.

The mean of the sample is (3 + 5 + 12 + 3 + 2)/5 = 5.

To find the standard deviation, we first need to calculate the variance. The variance can be found by taking the sum of the squared differences between each data point and the mean, dividing by the sample size minus one, and then taking the square root.

The variance is ((3-5)² + (5-5)² + (12-5)² + (3-5)² + (2-5)²)/4 = 20.5.

The standard deviation is the square root of the variance, which is approximately 4.53.

Finally, we can calculate the coefficient of variation by dividing the standard deviation by the mean and multiplying by 100%.

Coefficient of variation = (4.53/5) x 100% = 90.6%.

The angle formed by this intersection point and the corresponding point on LMNO is congruent to ZH.

In this case, we have two figures, LMNO and HIJK, and we know that LMNO is a reflection of HIJK. This means that there is an axis of reflection that maps HIJK onto LMNO.

When a shape is reflected across a line of symmetry, its angles are preserved. That is, if two angles in the original shape are congruent, then their images in the reflected shape are also congruent.

In this case, ZH is an angle in HIJK, and we want to find the angle in LMNO that corresponds to it. To do this, we need to find the line of symmetry that maps HIJK onto LMNO.

Once we have identified this line, we can draw the perpendicular bisector of ZH and find where it intersects the line of symmetry. The angle formed by this intersection point and the corresponding point on LMNO is congruent to ZH.

The length of v, to the nearest 10th of a centimeter is 2.2.

To find the length of side v in triangle UVW, we can use the law of sines, which states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all sides and angles in the triangle.

Using this formula, we have,

v/sin(m∠V) = w/sin(m∠W)

We know that w = 1.4 cm and m∠W = 63°. To find sin(m∠W), we can use a calculator,

sin(63°) ≈ 0.89

Substituting the values we know into the formula, we get,

v/sin(m∠V) = 1.4/0.89

To solve for v, we need to find sin(m∠V). We know that the sum of the angles in a triangle is 180°, so we can find m∠V by subtracting the measures of the other two angles from 180°,

m∠V = 180° - m∠U - m∠W

m∠V = 180° - 29° - 63°

m∠V = 88°

Now, we can substitute the value of sin(m∠V) into the equation and solve for v,

v/ sin(88°) = 1.4/0.89

v ≈ 2.2 cm

Therefore, the length of side v in triangle UVW is approximately 2.2 cm to the nearest tenth of a centimeter.

As three dice are thrown together and the probability of any two of them being the same will be 5/12.

When a dice is thrown there are 6 possible outcomes. So, when three dice are thrown, the number of outcomes will be 6× 6× 6 = 216.

The probability of a number repeating = ₆C₂ = (6×5)/2 = 15

So each number will have possible 15 outcomes.

6 numbers will have 6 × 15 outcomes = 90 outcomes

So probability = Number of desired outcomes/ total number of outcomes  = 90 / 216 = 5/12

So the probability of any two number matches when three dices are thrown together will be 5/12.

The circumference of the circle is approximately 54.1 yards.

Circumference is a term used to describe the distance around the edge of a circular object. It is a measurement of the total length of the circle's perimeter. The circumference of a circle is calculated by multiplying its diameter by the mathematical constant pi (π), which is approximately equal to 3.14.

The formula for calculating circumference is C=πd or C=2πr, where C represents the circumference, d represents the diameter, and r represents the radius of the circle. The diameter is the distance across the circle, passing through its center, while the radius is the distance from the center to the edge.

Circumference is a fundamental concept in geometry and is used to solve various real-world problems, such as calculating the distance traveled by a rotating wheel or finding the length of a wire needed to make a circular ring. Additionally, many physical phenomena, such as the movement of planets and the orbits of electrons, can be described using the concept of circumference.

The circumference of a circle with a radius of 8.6 yards can be found using the formula:

C = 2πr

where r is the radius and π is the mathematical constant approximately equal to 3.14.

Substituting the given value of the radius, we get:

C = 2 × 3.14 × 8.6

C = 54.088

Rounding this to the nearest tenth, we get:

C ≈ 54.1 yards

The probability that the pirate will encounter exactly 3 islands with treasure and none with traps while searching all 6 islands is approximately 0.240 or 24%.

Let's calculate the probability that the pirate will encounter exactly 3 islands with treasure and none with traps.

First, we need to consider the probabilities for each outcome on each island:

P(treasure) = 1/4

P(traps) = 1/12

P(neither treasure nor traps) = 2/3

Now, we want to find the probability of encountering 3 islands with treasure and none with traps out of 6 islands. This is a binomial probability problem, where n is the number of trials (6 islands) and k is the number of successful outcomes (3 islands with treasure). The probability of success (p) is the probability of finding treasure on an island (1/4), and the probability of failure (q) is the probability of not finding traps on an island (1 - 1/12 = 11/12).

The binomial probability formula is:

[tex]P(X = k) = \binom{n}{k} \cdot p^k \cdot q^{n-k}[/tex]

where:

[tex]\binom{n}{k} = \frac{n!}{k! \cdot (n-k)!}[/tex]

Plugging in the values:

n = 6 (number of islands)

k = 3 (number of islands with treasure)

p = 1/4 (probability of finding treasure on an island)

q = 11/12 (probability of not finding traps on an island)

[tex]P(X = 3) = \binom{6}{3} \cdot \left(\frac{1}{4}\right)^3 \cdot \left(\frac{11}{12}\right)^3[/tex]

Calculating (6 choose 3):

[tex]\binom{6}{3} = \frac{6!}{3! \cdot (6-3)!} = 20[/tex]

Now, plug in the values:

[tex]P(X = 3) = \binom{6}{3} \cdot \left(\frac{1}{4}\right)^3 \cdot \left(\frac{11}{12}\right)^3 \approx 0.240[/tex]

The equation of g(x) in parabola vertex form is g(x) = (x + 4)^2 + 3. Option (D) is the correct answer.

Since the vertex of the parabola is at (-4, 3), we can write the equation of the parabola in vertex form as:

g(x) = a(x + 4)^2 + 3

where "a" is a constant that determines the shape of the parabola. Since the parabola opens upward, "a" must be positive.

We also know that the parabola passes through the points (-6, 7) and (-2, 7). Substituting these values into the equation above, we get:

7 = a(-6 + 4)^2 + 3

7 = 4a + 3

4a = 4

a = 1

Substituting "a = 1" into the equation above, we get:

A mathematical model is a representation of a real-world system, process, or phenomenon using mathematical concepts, equations, and symbols. The purpose of creating a mathematical model is to understand and analyze the behavior of the system under different conditions and to make predictions about its future behavior.

Mathematical models can be used in various fields, including physics, engineering, economics, biology, and social sciences. They can range in complexity from simple algebraic equations to sophisticated computer simulations and can incorporate various factors such as time, space, and multiple variables.

The median is the best measure of center because there are no outliers present.

In the given line plot, we have the following data points for the cost of used books in dollars:

1 at $2, 1 at $4, 3 at $3, 1 at $8, 2 at $6, 2 at $7, and 1 at $9.

To decide which measure of center is most appropriate, let's first understand the difference between the mean and the median.

Mean: The mean is the sum of all the data points divided by the number of data points. It is sensitive to outliers, which means that if there are extreme values in the data, the mean can be significantly affected.

Median: The median is the middle value of a dataset when the data points are arranged in ascending order. If there are an even number of data points, the median is the average of the two middle values. The median is less sensitive to outliers, making it a more robust measure of center when extreme values are present.

Now, let's examine the given data for any outliers. There doesn't seem to be any extreme values in the data; the costs are fairly close together. However, the data is slightly skewed to the right, which means there is a higher concentration of lower values.

In this case, the median would be a better measure of center because it is less sensitive to the skewed distribution.

To find the median, first, arrange the data in ascending order:

$2, $3, $3, $3, $4, $6, $6, $7, $7, $8, $9

There are 11 data points, so the middle value is the 6th data point:

Median = $6

Thus, the median is the most appropriate measure of center for this data, and the median cost of used books is $6.

All four zeros are real solutions in the polynomial equation.

What are polynomials in equations?

A polynomial is an expression that consists of one or more variables, coefficients, and non-negative integer exponents of the variables. An equation is a mathematical statement with an equal sign between two algebraic expressions with equal values. 

x⁴ – 41 x² = – 400

Adding 400 on both sides to get rid 400 from right side and set 0 on right side, we get

       x⁴ - 41x² + 400 = -400 + 400

     x⁴ - 41x² + 400 = 0

Factoring by product sum rule.

We need product of 400 and sum upto -41.

We can see that 400 = -25 × -16 = 400 and -25-16 = -41.

Therefore,

         x⁴ - 25x² - 16x²  + 400 = 0

Making it into two groups, we get

  (x⁴ - 25x²) + (-16x² + 400) = 0

Factoring out GCF of each group, we get

  x²(x² - 25) (x² - 16) = 0

(x² - 25) = x² - 5²  = (x - 5) (x + 5)

x² - 16 = x² - 4² = (x - 4)(x + 4)

(x - 5) (x + 5) (x - 4)(x + 4) = 0

Applying zero product rule,

x-5=0

x+5=0

x-4=0 and

x+4=0.

Therefore,

x = -5, -4, 4 and 5.

All four zeros are real solutions.
