Answer:

The best way to decompose the composite figure to determine its area is as a semicircle, a trapezoid, and two rectangles. This way, we can use the following formulas to find the area of each part:

Area of a semicircle = 21​πr2, where r is the radius of the circle.

Area of a trapezoid = 21​(b1​+b2​)h, where b1​ and b2​ are the bases and h is the height of the trapezoid.

Area of a rectangle = l×w, where l is the length and w is the width of the rectangle.

Then, we can add up the areas of each part to find the total area of the composite figure. The other options are not as convenient because they either involve more parts or more complicated shapes. For example, option A would require finding the area of a triangle, which involves using trigonometry or the Pythagorean theorem. Option B would require finding the area of four triangles, which is more tedious than finding the area of two rectangles. Option C would require finding the area of a square, which is redundant because a square is a special case of a rectangle.

Step-by-step explanation:

The composite figure can be decomposed into a semicircle, a trapezoid, and two rectangles.

Option D is the correct answer.

It is a quadrilateral that has one pair of parallel sides and a height.

The area is calculated as: 1/2 x sum of the parallel sides x height.

Examples:

Area of a trapezium that has the parallel sides as 3 cm and 4 cm and a heght o 5 cm.

Area = 1/2 x (3 + 4) x 5

Area = 1/2 x 7 x 5

Area = 35/2 = 17.5 cm^2

Approximately 68.27% of the data will fall between 42 and 54. 0.13% of the data will be greater than 66. A large percentage of the data falls between these values, but we cannot provide an exact percentage. The z-score of element 33 is -2.5  indicates that the element is 2.5 standard deviations below the mean.

To solve these questions, we can use the properties of the normal distribution and z-scores.

a. To find the percentage of data that falls between 42 and 54, we need to calculate the z-scores for these values and then find the area under the normal curve between those z-scores.

The z-score formula is:

z = (x - μ) / σ

For 42:

z1 = (42 - 48) / 6 = -1.0000

For 54:

z2 = (54 - 48) / 6 = 1.0000

Using a standard normal distribution table or a calculator, we can find the area between these two z-scores.

Area between z1 and z2 = P(z1 < Z < z2) = P(-1 < Z < 1) ≈ 0.6827

Therefore, approximately 68.27% of the data will fall between 42 and 54.

b. To find the percentage of data that will be greater than 66, we need to calculate the z-score for 66 and find the area to the right of that z-score.

For 66:

z = (66 - 48) / 6 = 3.0000

Using a standard normal distribution table or a calculator, we can find the area to the right of this z-score.

Area to the right of z = P(Z > z) = P(Z > 3) ≈ 0.0013

Therefore, approximately 0.13% of the data will be greater than 66.

c. When the distribution of the data is unknown, we cannot make exact calculations based on the normal distribution. However, if we assume that the data is approximately normally distributed, we can estimate the percentage of data falling between certain values.

Since the data is unknown, we can use a rough estimate based on the empirical rule (also known as the 68-95-99.7 rule). According to this rule, for a bell-shaped distribution:

- Approximately 68% of the data falls within one standard deviation of the mean.

- Approximately 95% of the data falls within two standard deviations of the mean.

- Approximately 99.7% of the data falls within three standard deviations of the mean.

Since the mean is 48 and the standard deviation is 6, we can estimate that a large percentage of the data falls between 36 and 60. However, we cannot provide an exact percentage without knowing the specific shape of the distribution.

d. Similarly, assuming the distribution is unknown, we can use the rough estimate based on the empirical rule. The range between 39 and 57 is within two standard deviations of the mean. Therefore, we can estimate that a large percentage of the data falls between these values, but we cannot provide an exact percentage.

c. The z-score measures the number of standard deviations an individual element is away from the mean. To compute the z-score for an element of 33 in this case, we use the formula:

z = (x - μ) / σ

For 33:

z = (33 - 48) / 6 = -2.5

The z-score of -2.5 indicates that the element is 2.5 standard deviations below the mean. In terms of interpretation, it means that the value of 33 is relatively low compared to the mean and standard deviation of the data set. It falls in the lower tail of the distribution.

Step-by-step explanation:

2. Yo multiplica 4.375 por 95. La respuesta es 415.625 km.

a) When Lily's age is 20, and Raphael's age is divided by 3 then the expression of Lily's age in terms of h is h < 10.

b) Ethan's age is half of Raphael's age therefore, Ethan's age is half Raphael's age.

a) If Raphael is twice as old as his sister Lily, we can represent their ages as 2h and h, respectively, where h is Lily's age. The sum of their ages is less than 30, so we can write the equation:

2h + h < 30

Combining like terms, we get:

3h < 30

Dividing both sides by 3, we get:

h < 10

This is an expression of Lily's age in terms of h.

b) If Ethan's age is 16, and Raphael's age is twice Ethan's age, we can represent Raphael's age as 2 × 16 = 32.

Ethan's age is 16, which is half of Raphael's age of 32. Therefore, Ethan's age is half of Raphael's age.

The value of ∭E (x² + y²) dv over the region E between the given spheres.

To evaluate the integral ∭E (x² + y²) dv using spherical coordinates, we first need to express the volume element dv in terms of spherical coordinates.

In spherical coordinates, the volume element is given by dv = r² sin(φ) dr dφ dθ, where r represents the radial distance, φ represents the polar angle, and θ represents the azimuthal angle.

Since we are integrating over the region E between the spheres x² + y² + z² = 9 and x² + y² + z² = 16, the limits of integration for r, φ, and θ will be as follows:

r: from the lower sphere to the upper sphere, which corresponds to r = 3 to r = 4

φ: from 0 to π (since we are considering the entire range of polar angle)

θ: from 0 to 2π (since we are considering the entire range of azimuthal angle)

Now, let's substitute these values and evaluate the integral:

∭E (x² + y²) dv = ∭E (r² sin(φ) cos²(θ) + r² sin(φ) sin²(θ)) dr dφ dθ

Integrating over θ from 0 to 2π, and integrating over φ from 0 to π, we have:

∭E (x² + y²) dv = ∫[0,2π] ∫[0,π] ∫[3,4] (r² sin(φ) cos²(θ) + r² sin(φ) sin²(θ)) dr dφ dθ

Now, we can evaluate the integral by performing the integration step by step, starting from the innermost integral.

After evaluating the integral, the final result will give us the value of ∭E (x² + y²) dv over the region E between the given spheres.

Given two right triangle legs

Use the Pythagorean theorem to calculate the hypotenuse from the right triangle sides. Take a square root of sum of squares: c = √(a² + b²)

Step-by-step explanation:

The hypotenuse can be discovered using Pythagoras' Theorem.

The definition of "the longest side of a right triangle" is simply "hypotenuse." The triangle's hypotenuse is the side that faces away from the right angle. It is also the triangle's longest side.

The Pythagorean theorem is formalized mathematically via the hypotenuse formula. It states that the square of the length of the hypotenuse c is equal to the sum of the squares of the lengths of the shorter two sides of the triangle, a and b: a2+b2=c2.

The 3:4:5 triangle is the only way to know for sure if an angle is 90 degrees. According to this rule, a triangle cannot be a right triangle if one side of the triangle measures 3 and the other side measures 4 and the diagonal connecting those two locations does not measure 5.

The equation of a line perpendicular to y=-2 x+6 containing (3,2) in slope-intercept form: y = 0.5 x - 0.5

Two lines are perpendicular if their slopes are negative reciprocals of each other. The slope of y=-2 x+6 is -2, so the slope of the perpendicular line will be 1/2.

We can plug the point (3,2) into the slope-intercept form of a line, y = mx + b, to solve for b, the y-intercept.

```

2 = (1/2) * 3 + b

```

```

2 = 1.5 + b

```

b = 2 - 1.5 = 0.5

There is gain of $1,000 on the sale. The solution has been obtained by using the arithmetic operations.

What are arithmetic operations?

All real numbers are believed to be able to be described by the four fundamental operations, often known as "arithmetic operations". Quotient, product, sum, and difference are the next four mathematical operations after division, multiplication, addition, and subtraction.

We are given that an equipment costing $135,000 has a book value of $124,000 and it is sold for $125,000.

Since, the sale value is higher than the book value, therefore there is a gain.
