A danger that is associated with using extrapolation when making predictions is assuming that the underlying patterns will continue into the future.

One danger of using extrapolation when making predictions is that it assumes that the underlying patterns observed in the data will continue into the future.

However, there may be external factors or other variables that are not accounted for in the data that could cause the patterns to change or break down. For example, if there is a major economic or political event that affects the housing market, the trend observed in previous data may not hold up in the future.

The equation is given by 5n + 100n = 210

Peggy has 8 quarters and 2 nickels

Let's call q the number of quarters and n the number of nickels.

If Peggy has four times as many quarters as nickels, we can write the following equation:

q = 4n

Then, each quarter has a value of 0.25 dollars and each nickel has a value of 0.05 dollars, so

0.25q + 0.05n = 2.10

Because she had $2.10. Now, we can replace the first equation on the second one

0.25(4n) + 0.05n = 2.10

1n + 0.05n = 2.10

Finally, we can multiply both sides by 100, so

100n + 0.05(100)n + 2.10(100)

100n + 5n = 210

Therefore, the equation that can be used to solve the problem is

5n + 100n = 210

Now, we can solve the equation for n

105n = 210

105n/105 = 210/105

n = 2

Then, q is equal to

q = 4n

q = 4(2)

q = 8

It means that Peggy has 8 quarters and 2 nickels.

Answer:

Step-by-step explanation:

The strength of a linear relationship between two variables is typically measured by the correlation coefficient (r) or the coefficient of determination (r^2). A value of r or r^2 closer to 1 indicates a stronger positive linear relationship, whereas a value closer to -1 indicates a stronger negative linear relationship. A value of r or r^2 closer to 0 indicates a weaker or no linear relationship.

Looking at the given regression equations and their correlation coefficients, the regression with the weakest linear relationship between x and y is Regression 3:

Regression 1: y = -5.8x - 6.5, r = -0.7621

Regression 2: y = 2.4x - 14.7, r = 0.809

Regression 3: y = -7.4x - 17.4, r = -0.233

Regression 4: y = -3.4x - 8.5, r = -0.6121

Regression 3 has the lowest absolute value of r (0.233), indicating the weakest or no linear relationship between x and y. Therefore, Regression 3 represents the weakest linear relationship between x and y among the given options.

The benefit of doing so is: If the teenager has earned less than $12,000 then they don't get the federal taxes withheld. It would be beneficial to the teen because they would get more money.

A teen might want to claim exemption from federal income taxes being withheld from their paycheck if they expect to earn less than the standard deduction amount for the tax year and they will not owe any federal income tax.

For the tax year 2022, the standard deduction amount for a single taxpayer who is not claimed as a dependent on another taxpayer's return is $12,950.

By claiming exemption from federal income taxes, the teen would have more money in their paycheck and would not have to wait to receive a tax refund when they file their tax return at the end of the year.

However, if the teen ends up earning more than the standard deduction amount or if they have other sources of taxable income, they may owe federal income tax and may have to pay a penalty for not having enough taxes withheld during the year.

The equation of the axis of symmetry for the parabola is x = 2.

What is the axis of symmetry?

The object's shape is symmetrical because of the axis of symmetry, which is a straight line. On each of its sides, the axis of symmetry produces an exact reflection. It might be lateral, vertical, or horizontal. The two sides of an object are the same if we fold and unfold it along the axis of symmetry. Different shapes have various symmetry lines. There are four lines of symmetry in a square, two lines in a rectangle, infinite lines in a circle, and no lines of symmetry in a parallelogram. There are n axes of symmetry in a regular polygon with n sides.

Given equation of the parabola is

y = 2/3 (x - 2)² - 5

The general form of a parabola is y = a(x - h)² + k.

The vertex of the parabola is (h,k).

The equation symmetric axis is x = h.

Now compare the equation y = 2/3 (x - 2)² - 5 with y = a(x - h)² + k:

a = 2/3, h = 2, k = -5

The equation of the axis of symmetric is x = 2.

The value of temperature 75degrees Fahrenheit converted to Celsius is 23.89 degrees Celsius.

To convert 75 degrees Fahrenheit to Celsius, you can use the formula

(F - 32) x 5/9.

Here's how to use this formula:

Subtract 32 from 75: 75 - 32 = 43

Multiply 43 by 5/9: 43 x 5/9 = 23.89

So 75 degrees Fahrenheit is equivalent to 23.89 degrees Celsius. To remember this formula easily, you can use the mnemonic "Fahrenheit to Celsius, subtract 32, then divide by 1.8".

The angle of polygons is an important concept in geometry and can be calculated using the formula (n-2) x 180. Quadrilaterals are a specific type of polygon with four sides and four angles, and their interior angles can be found by dividing the sum of the interior angles by the number of sides.

The angle of polygons is an important concept in geometry. A polygon is a closed shape with three or more sides, and the angles of a polygon are the interior angles formed by the sides. Quadrilaterals are a specific type of polygon with four sides and four angles.

To find the sum of the interior angles of a polygon, you can use the formula (n-2) x 180, where n is the number of sides. For example, a quadrilateral has four sides, so the sum of its interior angles would be (4-2) x 180 = 360 degrees.

Each individual angle of a quadrilateral can be found by dividing the sum of the interior angles by the number of sides. So for a quadrilateral, each angle would be 360/4 = 90 degrees.

Answer: 9 laps in 1 day = 18 laps in 2 days

Step-by-step explanation:

To complete the proportion, we can use the fact that the number of laps is directly proportional to the number of days:

9 laps in 1 day = 18 laps in x days

To solve for x, we can use the property of proportions that the product of the means equals the product of the extremes:

9 laps × x days = 1 day × 18 laps

Simplifying, we get:

9x = 18

Dividing both sides by 9, we get:

x = 2

Therefore, the missing number to complete the proportion is 2. The complete proportion is:

9 laps in 1 day = 18 laps in 2 days

Answer: 2 days

Step-by-step explanation: 9 + 2 equals 18 therefor 18 laps in 2 days

The mathematics curriculum covers the study of number and their variable as well as our surroundings, architecture, and both actual and hypothetical locations. The link between the amounts of inputs as well as the associated outputs for each is shown graphically by a function. A function is, to put it simply, a group of inputs whose, when combined, result in particular outputs for every input. Each role is assigned a region, locale, or range .

Here,

Given :

f(x) = -x² + 14x³ - 24x⁷ - 10x¹² + 22x⁴ - 18x¹¹ + 4x⁴  +21

To describe the end behavior of the given polynomial function f(x), we only need to consider the term with the highest degree, which is - 10x¹²

Since the degree of the term is even and the coefficient is negative, we know that as x approaches positive or negative infinity, the function will also approach negative infinity.

Therefore, we can say:

As x to -∞, f(x)  to - ∞

As x to +∞, f(x) to-∞

So the end behavior of the function

f(x) = -x² + 14x³ - 24x⁷ - 10x¹² + 22x⁴ - 18x¹¹ + 4x⁴  +21

A figure has reflectional symmetry if it can be reflected across a line and still look the same. For the capital letter H, there is two lines of symmetry, which is the vertical line and horizontal line that divides the letter into two equal halves. Reflecting the letter across this line produces the same letter. So, the H has only 2 reflectional symmetries.
