Answer:By adding a constant value to every salary amount, the measures of

central tendency are increased by the amount, while the measures of

dispersion, remains the same

The correct responses are;

(a) The shape of the data remains the same

(b) The mean and median are increased by $1,000

(c) The standard deviation and interquartile range remain the same

Reasons:

The given parameters are;

Present teachers salary = Between $38,000 and $70,000

Amount of raise given to every teacher = $1,000

Required:

Effect of the raise on the following characteristics of the data

(a) Effect on the shape of distribution

The outline shape of the distribution will the same but higher by $1,000

(b) The mean of the data is given as follows;

Therefore, following an increase of $1,000, we have;

Therefore, the new mean, is equal to the initial mean increased by 1,000

Median;

Given that all salaries, , are increased by $1,000, the median salary, , is also increased by $1,000

Therefore;

The correct response is that the median is increased by $1,000

(c) The standard deviation, σ, is given by ;

Where;

n = The number of teaches;

Given that, we have both a salary, , and the mean, , increased by $1,000, we can write;

Therefore;

; The standard deviation stays the same

Interquartile range;

The interquartile range, IQR = Q₃ - Q₁

New interquartile range, IQR = (Q₃ + 1000) - (Q₁ + 1000) = Q₃ - Q₁ = IQR

Therefore;

The interquartile range stays the same

The solution of the equation 12x + 31 = 15 is x = -4/3

In this question we have been given an equation.

12x + 31 = 15

We need to find the solution of the given equation.

12x + 31 = 15

12x + 31 - 31 = 15 - 31                 ..............(Subtract 31 from each side)

12x = -16

x = -16/12                                   .............(Divide each side by 12)

x = -4/3

Therefore, the solution of the equation 12x + 31 = 15 is x = -4/3

Step-by-step explanation:

the €300 as current price is 125% relative to the original price. in other words : 1.25 times the original price.

to get the amount of the increase we need to get the original price first and then subtract the original price from the current price.

to get the original price we need now to divide the actual price by 1.25 to undo the increase.

the original price

OP = 300/1.25 = €240

the price increase (of 25%) was then

300 - 240 = €60

A) The amount that the retailer should charge for each candle in order to maximize its profit is; $27

B) The domain of the function is; x ≥ 120

The range of the function is; P(x) ≥ 3645

A) Let the total sales be represented by P(x).

Let the number of candles sold be x.

Now, since the retailer  120 jar candles at $30 per candle and estimated that or each $2 decrease in price, they will sell 10 additional candles.. Thus;

P(x) = (30 - 2 * (x - 120)/10)x

P(x) = 30x - x²/5 + 24x

P(x) = - x²/5 + 54x

Using -b/2a, we can get the number of candles that maximizes profit as;

-54/(2 * -1/5) = 135 candles

Plugging 135 for x into the P(x) equation gives;

P(135) = $27

B) The domain of the function is; x ≥ 120

The range of the function is; 135 * 27 = 3645

Road signs, often known as traffic signs, are posted along the side of roadways or above them to inform and direct drivers. Simple wooden or stone milestones were the oldest types of signs. Later, directional signs with arms were developed, such as the fingerposts used in the United Kingdom and their wooden equivalents in Saxony. Since the 1930s, as traffic volumes have increased, many nations have adopted pictorial signs or have similarly standardized and simplified their signs in an effort to overcome linguistic barriers and improve traffic safety. Such pictorial signals are typically based on international norms and use symbols (often silhouettes) in place of words. These signs were initially created in Europe and have since been adopted in varied degrees by the majority of nations.

Given the volume, length and height, the width of the rectangular prism rounded to the nearest foot is 8ft.

The volume of a rectangular prism is expressed as;

V = w × h × l

Where w is the width, h is height and l is length.

Given the data in the question;

To determine the with of the rectangular prism, plug the given values into the formula above and solve for w.

V = w × h × l

528 ft³ = w × 11ft × 6ft

528 ft³ = w × 66ft²

Reorder the equation and divide both sides by 66ft²

w × 66ft = 528 ft³

( w × 66ft )/66ft² = 528 ft³ / 66ft²

w = 528 ft³ / 66ft²

w = 8ft

The value of KM is equal to 5.

A line segment is a section of a straight line that is enclosed by two clearly defined endpoints and contains every point on the line located within.

Consider a point L on a line segment KM such that:

We have the values,

KL = 3x ;

LM = 2

Now, we know,

KL + LM = KM

KM = 3x + 2                                                                                ---------(1)

Now, KM = x + 4                                                                         ---------(2)

Equating the equations (1) and (2),

We get,

3x + 2 = x + 4

Now, subtract 2 from each side of the equation.

3x + 2 - 2 = x + 4 - 2

3x = x + 2

Subtracting x from each side of the equation.

3x - x = x + 2 - x

2x = 2

Dividing each side of the equation by 2.

The required polynomial function is x^4 + 8x³ + 22x² + 24x + 9

In this question,

We have been given  the zeros of a polynomial and the degree of a polynomial.

We need to find the polynomial of degree 4 and has zeros x = -3, -1

If a polynomial function f(x) has zeros x = -3, x = -1, then it has factors

(x + 3), (x + 1).

If these were its only factors, then polynomial would be a quadratic.

This means, both the zeros must be of multiplicity 2.

So, the roots of the polynomial must be of the form f(x) = (x + 3)²(x + 1)²

f(x) = (x + 3)²(x + 1)²

f(x) = (x² + 6x + 9)(x² + 2x + 1)

f(x) = x^4 + 8x³ + 22x² + 24x + 9
