The percentage of rents that are greater than $1,900 is 2.28%.

a) What percentage of rents are between $1,300 and $1,700?The average rent in a city is $1,500 per month with a standard deviation of $200.

Assume rent follows the normal distribution.z = (x - μ) / σLet X be a random variable denoting the rent in a city.

Then,μ = $1500σ = $200z1 = (1300 - 1500) / 200 = -1z2 = (1700 - 1500) / 200 = 1P(1300 < X < 1700) = P(-1 < z < 1) = P(z < 1) - P(z < -1) = 0.8413 - 0.1587 = 0.6826

Therefore, the percentage of rents that are between $1,300 and $1,700 is 68.26%.

b) What percentage of rents are less than $1,300?z = (x - μ) / σz = (1300 - 1500) / 200 = -1P(X < 1300) = P(Z < -1) = 0.1587Therefore, the percentage of rents that are less than $1,300 is 15.87%.

c) What percentage of rents are greater than $1,900?z = (x - μ) / σz = (1900 - 1500) / 200 = 2P(X > 1900) = P(Z > 2) = 0.0228

Therefore, the percentage of rents that are greater than $1,900 is 2.28%.

The measure of angle x in the right triangle is approximately 14.6 degrees.

The figure in the image is that of two right angles.

First, we determine the hypotenuse of the left-right angle.

Angle θ = 30 degrees

Adjacent to angle θ = 10 cm

Hypotenuse = ?

Using the trigonometric ratio.

cosine = adjacent / hypotenuse

cos( 30 ) = 10 / hypotenuse

hypotenuse = 10 / cos( 30 )

hypotenuse = \(\frac{20\sqrt{3} }{3}\)

Using the hypotenuse to solve for x in the adjoining right triangle:

Angle x =?

Adjacent to angle x = \(\frac{20\sqrt{3} }{3}\)

Opposite to angle x = 3

Using the trigonometric ratio.

tan( x ) = opposite / adjacent

tan( x ) = 3 / \(\frac{20\sqrt{3} }{3}\)

tan (x ) = \(\frac{3\sqrt{3} }{20}\)

Take the tan inverse

x = tan⁻¹(  \(\frac{3\sqrt{3} }{20}\) )

x = 14.6 degrees

Therefore, angle x measures 14.6 degrees.

The accounting equation is a fundamental principle in accounting that states that assets equal liabilities plus equity. Using this equation, missing amounts can be determined in various situations.

The accounting equation is expressed as Assets = Liabilities + Equity. It serves as the foundation for double-entry bookkeeping and ensures that the financial statements are balanced. By rearranging the equation, missing amounts can be determined.

For example, if the assets and equity are given, the missing amount of liabilities can be calculated by subtracting equity from assets. Conversely, if the liabilities and equity are known, the missing amount of assets can be calculated by adding liabilities to equity.

Similarly, if the assets and liabilities are provided, the missing amount of equity can be calculated by subtracting liabilities from assets. Alternatively, if the assets and equity are known, the missing amount of liabilities can be calculated by subtracting equity from assets.

In each situation, the missing amount can be determined by applying the accounting equation and rearranging it to solve for the missing variable. This equation provides a framework for ensuring that all financial transactions are properly recorded and that the financial statements accurately reflect the financial position of a business.

T/F Solution that can be analytically obtained but is not an actual answer to the equation often due to restrictions in the type of function such as a negative in the log

This statement is true.

Because, Sometimes, when solving an equation using analytical methods, we may arrive at a solution that is mathematically correct but is not a valid answer due to the restrictions in the type of function used.

For example, if a negative value appears in the logarithmic function, the solution may not be valid because the logarithmic function is only defined for positive values.

In such cases, we need to go back and recheck our work and take into account the restrictions of the function to arrive at a valid solution.

Sometimes when solving an equation analytically, the resulting solution may not be a valid answer due to restrictions in the domain of the function.

For example, if we solve an equation involving a logarithmic function, we may end up with a negative value inside the logarithm, which is not defined for real numbers. In such cases, the solution obtained analytically is not a valid answer to the equation.

Another example is when solving for the roots of a quadratic equation using the quadratic formula, we may obtain complex solutions even though we are only interested in real solutions.

Thus, it is important to always check the solutions obtained to ensure that they satisfy any domain or range restrictions of the functions involved in the equation.

The angles that cannot be an interior angle in a regular polygon are 40 72° 108° 148°

A polygon is a closed polygonal chain made up of a limited number of straight line segments and is a type of planar figure in geometry. A polygon is an area that is bordered by a bounding circuit, a bounding plane, or both. A polygonal circuit's segments are referred to as its edges or sides.

A regular polygon has equal internal angles all around. A polygon's interior angle is calculated using the following formula: interior angle of a polygon = sum of interior angles number of sides. The total of a polygon's outer angles is 360°.

Given the different angles in degree.

We have to find angle which can't be interior angle in a regular polygon

We apply the formula for each angle = (n - 2) 180 / n to determine the size of each interior angle of a regular polygon.

Let the interior angle be  108 degree

(n - 2) 180 / n = 108

n = 0.5 not possible

Let the interior angle be  148 degree and 179 degree

(n - 2) 180 / n = 148

n = 1.125 not possible

(n - 2) 180 / n = 179

n = 36 possible

Let the interior angle be  40 degree and 72 degree

(n - 2) 180 / n = 40

n = 0.9 not possible

(n - 2) 180 / n = 72

n = 0.33 not possible

A regular polygon is a polygon which has equal internal angles all around it.

In a polygon, the interior angle = sum of interior angles number of sides.

Total outer angle of a polygon is 360°.

Here we have to find the angle which can't be an interior angle of a regular polygon.

The size of each interior angle of a regular polygon = [(n-2)×180°] /n

1. 108 degree

[(n-2)×180°] /n = 108

180n - 360 = 108n

72n=360

n = 0.2 This is not possible since n is a natural number

2. 148 degree

[(n-2)×180°] /n = 148

180n - 360 = 148n

72n=360

n = 0.2 This is not possible since n is a natural number

Let the interior angle be 148 degree and 179 degree

(n-2) 180 / n = 148

n = 1.125 not possible

(n-2) 180 / n = 179

(n-2) 180 / n = 40

Hence angles that cannot be an interior angle in a regular polygon are 40 72° 108° 148°

The corresponding sides and angles of two polygons ABCD and ZYXW must be proportionate if they are identical.

With straight sides around its perimeter, a polygon is really a circular, two-dimensional, flat of planar structure. Its sides are straight with no bends. Another term for a polygon's sides is its edges. The points at which two sides of a polygon converge are known as its vertices (or corners). These are numerous examples of polygonal geometry.

A closed polygon is a form with more than three sides. A quadrilateral is a 4-sided polygonal shape. A quadrilateral is any closed 4-sided form, however there are six particular quadrilaterals with distinctive characteristics that give them their own names.

Have A Wonderful Day !!

The probability of the weekend being dry for the school picnic is approximately 23.4%.

First, let's define some terms:

1. Probability: The likelihood of a specific event happening
2. Picnic: The school event that is scheduled for a two-day weekend in May
3. Rainy: Refers to days with rain

Now, let's calculate the probability that the weekend will be dry:

There are 16 rainy days in May, and May has 31 days. So, there are (31 - 16) = 15 dry days in May.

Each weekend has two days. Since May has 31 days, there are (31 / 7) = approximately 4.43 weeks in May. To account for the remaining days, we round down to 4 weeks and add the remaining 2 days as another weekend, resulting in 5 weekends.

Now, we'll determine the probability of having a dry day on any given day in May:

Dry day probability = (number of dry days) / (total days in May) = 15 / 31 ≈ 0.484

Since we want the probability of having two consecutive dry days (the whole weekend), we'll multiply the probabilities of each day being dry:

Weekend probability of being dry = (dry day probability) * (dry day probability) ≈ 0.484 * 0.484 ≈ 0.234

So, the probability of the weekend being dry for the school picnic is approximately 23.4%.
