A standard normal distribution table or a calculator again, we can find that the z-score that corresponds to this area is approximately 0.42.

The standard normal distribution is useful because it allows us to calculate probabilities for any normal distribution by converting the distribution to a standard normal distribution using a process called standardization. Standardization involves subtracting the mean of the distribution from each observation and then dividing by the standard deviation. The resulting values are called z-scores, and they represent the number of standard deviations that an observation is from the mean of the distribution.

Assuming a standard normal distribution, we know that 0.5 of the area lies between -z and z, since the normal distribution is symmetric around the mean. Therefore, we need to find the value of z such that the area between -z and z is 0.6318 - 0.5 = 0.1318.

Using a standard normal distribution table or a calculator, we can find that the area between the mean and z is 0.5 + 0.1318/2 = 0.5659. Therefore, the z-score that corresponds to this area is approximately 0.18.

Since the distribution is symmetric, the area between -z and z is twice the area between the mean and z, so we can solve for z:

0.1318/2 = 0.0659 of the area lies between the mean and z

Using a standard normal distribution table or a calculator again, we can find that the z-score that corresponds to this area is approximately 0.42.

Therefore, z = 0.42 rounded to two decimal places.

Here no figure just go through the definition.

A polygon is a two-dimensional geometric shape that is defined as a closed figure with straight sides. It is made up of line segments that connect at endpoints called vertices. The term polygon comes from the Greek words "poly" meaning many and "gonia" meaning angle, indicating that polygons have many angles.

Polygons can have different numbers of sides, with the most basic being a triangle, which has three sides and three angles. Other examples of polygons include squares, rectangles, pentagons, hexagons, and octagons. The sides of a polygon do not have to be equal in length or the angles between them do not have to be the same, but they must be straight lines and the polygon must be closed.

The quadratic regression function f(x) = -0.1536x² + 3.3915x + 88.738, then estimate value for the number of people in the park when there are 80 birds is equals to the 24.

A quadratic regression is the process of finding the equation of the parabola that best fits a set of data. An equation of the form, y = ax² + bx + c where a≠0. We have a quadratic regression function is defined by f(x) = -0.1536x² + 3.3915x +88.738 --(1), where, f(x) = the number of birds in a park relative to the number of people x in the same park. We have to determine quadratic regression to estimate the number of people in the park when there are 80 birds. Now, f(x) = 80, substitute the known value in equation (1),

=> 80 = -0.1536x² + 3.3915x +88.738

=>0.1536x²- 3.3915x -88.738 + 80 = 0

=> 0.1536x²- 3.3915x - 8.738 = 0

=> x² - 22.08x - 56.88 = 0 --(2)

Using the quadratic formula for solution of (2), x = (-b ±√b² - 4ac)/2a, for ax² + bx + c = 0. So, [tex]x =\frac{ -(-22.08) ± \sqrt{(22.08)² + 4× 56.88}}{2}[/tex]

Step-by-step explanation:

Stocks x per share = return

Trey's return on investment, if the stock paid no dividends during the year, is 14.29%.

We have,

Purchase price per share: $50

Number of shares purchased: 200

Total purchase cost (excluding loan interest):

Purchase price per share * Number of shares purchased

= $50 * 200

= $10,000

Loan amount: $5,000

Loan interest rate: 10%

Interest paid on the loan:

Loan amount * Interest rate

= $5,000 * 10%

= $500

Total purchase cost (including loan interest):

Total purchase cost + Loan interest

= $10,000 + $500

= $10,500

Selling price per share: $60

Total revenue from selling the stock:

Selling price per share * Number of shares sold

= $60 * 200

= $12,000

Return on investment (ROI):

(Total revenue - Total purchase cost) / Total purchase cost

ROI = ($12,000 - $10,500) / $10,500

Simplifying the expression:

ROI = $1,500 / $10,500

ROI = 0.1429 (approximately)

To express the ROI as a percentage:

ROI as a percentage = 0.1429 * 100 = 14.29%

Therefore,

Trey's return on investment, if the stock paid no dividends during the year, is 14.29%.

After answering the presented question, we can conclude that As an expression result, there are 24 4-letter code symbols that may be constructed without duplication using the letters P, D, Q, and X.

what is expression ?

An expression in mathematics is a collection of representations, digits, and conglomerates that mimic a statistical correlation or regularity. A real number, a mutable, or a combination of the two can be used as an expression. Mathematical operators include addition, subtraction, rapid spread, division, and exponentiation. Expressions are often used in arithmetic, mathematics, and form. They are employed in the representation of mathematical formulas, the solving of equations, and the simplification of mathematical relationships.

We may use the method for permutations of n items taken r at a time to compute the number of 4-letter code symbols that can be created with the letters P, D, Q, X without repetition:

n! / (n-r)! P(n,r) = n!

where n denotes the number of items (in this example, four letters) and r the number of things taken at once (in this case, 4).

Thus far, we have:

P(4,4) = 4! / (4-4)! = 4! / 0! = 4 x 3 x 2 x 1 / 1 = 24

Hence, As a result, there are 24 4-letter code symbols that may be constructed without duplication using the letters P, D, Q, and X.

What is the sum?

The sum is the result of adding two or more numbers together. The sum is found by performing the operation of addition, which involves combining the values of two or more quantities to find the total or the sum.

If A = 80 - B and C = 70 - B, and the sum of A, B, and C is 100, then we can write:

A + B + C = 100

Substituting A and C with their given values, we get:

(80 - B) + B + (70 - B) = 100

Simplifying and combining like terms, we get:

150 - B = 100

Subtracting 150 from both sides, we get:

-B = -50

Dividing both sides by -1, we get:

B = 50

Now that we know B = 50, we can substitute this value back into the equations for A and C:

A = 80 - B = 80 - 50 = 30

C = 70 - B = 70 - 50 = 20

Therefore, the values of A, B, and C are 30, 50, and 20, respectively.

The surface area of the rectangular prism is 72 square meters.

A rectangular prism, also known as a rectangular parallelepiped, is a three-dimensional figure that consists of six rectangular faces. It is a polyhedron with two identical and parallel bases, which are rectangles, and four rectangular lateral faces. The height of the prism is the perpendicular distance between the two bases. The volume of a rectangular prism is given by the formula V = l × w × h, where l, w, and h are the length, width, and height of the prism, respectively. The surface area of a rectangular prism is given by the formula SA = 2lw + 2lh + 2wh, where l, w, and h have the same meanings as in the volume formula. Rectangular prisms are commonly encountered in everyday life, such as in the shape of boxes, rooms, and buildings.

The surface area of a rectangular prism can be found by adding up the area of all its faces.

Area of blue rectangles:

= 2 x (length x width)

= 2 x (2.4m x 2m)

= 9.6m²

Area of green rectangles:

= 2 x (length x width)

= 2 x (2.4m x 3m)

= 14.4m²

Area of yellow rectangles:

= 2 x (length x width)

= 2 x (2m x 3m)

= 12m²

Total surface area = sum of all face areas

= (2 x blue rectangles) + (2 x green rectangles) + (2 x yellow rectangles)

= 2(9.6m²) + 2(14.4m²) + 2(12m²)

= 19.2m² + 28.8m² + 24m²
