Step-by-step explanation:

For many of the rolls die, the long run relative frequency of a number less than 3 landing face up is 1/3.

What is relative frequency?

The proportion of outcomes where a specific event occurs to all trials, not in a hypothetical sample space but in a real experiment, is known as the empirical probability, relative frequency, or experimental probability of an event.

Given that, Only two integers (1 and 2) are smaller than 3, hence their relative frequency will be 2/6=1/3.

The best way to interpret the data is thus,

For many rolls of the die, the long- run relative frequency of a number less than three landing face up is1/3.

Hence option A is correct which is for many of the rolls die, the long run relative frequency of a number less than 3 landing face up is 1/3.

The inequality that the graph represent is y < -x + 1. The correct option is B. y < –x + 1

From the question, we are to determine the inequality that represents the given graph.

From the given information,

The line is passing through the coordinates (1, 0) and (-1, 2).

Using the formula for the equation of a line,

Using the formula,

(y - y₁)/(x - x₁) = (y₂ - y₁)/(x₂ - x₁)

Then,

(y - 0)/(x - 1) = (2 - 0)/(-1 - 1)

y/(x-1) = 2/-2

y/(x -1) = -1

y = -1(x -1)

y = -x + 1

Since the line is dotted and the shaded region is below the line, the inequality becomes

y < -x + 1

What is dilation?

Dilation is the increase or decrease in the size of a figure by a scale factor. Rigid transformations preserve the shape of a figure. Examples of rigid transformation are reflection, rotation and translation.

Resizing an item uses a transition called dilation. Dilation is used to enlarge or contract the items. The result of this transformation is a picture with the same shape as the original. However, there is a variation in the shape's size. The initial form should be stretched or contracted during a dilatation. The phrase "scale factor" describes this transition.

Dilation is said to be a rigid transformation if the scale factor is equal to one.

Therefore the dilation by a scale factor of one produce an image congruent to its pre-image.

For the first graph, slope = 1/5.

For the second graph, slope = -1/2.

For the third graph, slope = 2.

For the fourth graph, slope = 1.42.

What is the slope of the line?

The slope of a line is a measure of its steepness. Mathematically, the slope is calculated as "rise over run" (change in y divided by change in x).

                  [tex]m = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

For the first graph, the coordinates will be (-15, 0) and (0, 3)

          Slope = 3 - 0/0-(-15)

                     = 3/15

            Slope = 1/5

For the second graph, the coordinates will be (0, 5) and (10, 0)

          Slope = 0 - 5/10- 0

                     = -5/10

            Slope = -1/2

For the third graph, the coordinates will be (2.5, 0) and (0, -5)

          Slope = -5-0/0 - 2.5

                     = -5/-2.5

            Slope = 2

For the fourth graph, the coordinates will be (-2.8, 0) and (0, 4)

          Slope = 4 - 0/0 - (-2.8)

The revenue function of Patrice Bergeron earnings is R(x) = (50 + 5x)(20 -x)

From the question, we have the following parameters that can be used in our computation:

Charges  = $50

Students = 20

Also, we have:

For every $5/hr he increases the price, he loses one student.

This means that

Charges  = 50 + 5x

Students = 20 - x

So, the revenue equation is

R(x) = Charges * Students

Substitute the known values in the above equation, so, we have the following representation

R(x) = (50 + 5x)(20 -x)

Step-by-step explanation:

Think about the following scenarios

529.00 * 10

4 * 10 = 40 (4.00 * 10 =  40.0)

529 * 10 = 5290 (5290.00 * 10 =  5290.0)

As you can see, the decimal point is moving one space to the right when multiplying by ten.

In the decimal system, moving the decimal point one place to the right multiplies by ten, while moving the decimal point one place to the left multiplies by 1/10.

  b.  $1,135,868.40

  c.  $705,868.40

  d.  interest

Step-by-step explanation:

You want to find the monthly payment, total repaid, and finance charge on a 30-year mortgage for $430,000 at the rate of 8%.

You can use a spreadsheet, financial calculator, app, or the amortization formula to find the payment amount.

  A = P(r/12)/(1 -(1 +r/12)^(-12t))

where P is the principal amount of the loan, r is the annual interest rate, and t is the number of years.

  A = 430,000(0.08/12)/(1 -(1 +0.08/12)^(-12·30)) ≈ 3155.19

The monthly payment is $3,155.19.

The total of the 12·30 = 360 payments is ...

  360 · $3155.19 = $1,135,868.40

It will take about $1,135,868.40 to pay off the loan.

The finance charge is the difference between the amount repaid and the original loan amount:

  $1135868.40 -430000 = $705,868.40

The finance charge is $705,868.40.

The finance charge at $706k is considerably greater than the original cost of the home, $430k.

The finance charge is greater.

Bearing is a topic that deals with angles and distance. Thus, the required answers to the given question are:

i. Distance of 1034.2 miles

ii. Bearing of [tex]158^{o}[/tex]

The speed of an object is the rate of movement of the object with time.

speed = [tex]\frac{distance}{time}[/tex]

So that:

distance = speed x time

i. In the given question; let the initial distance covered be represented by d, so that:

d = 250 x 2

  = 500 miles

ii. Let the second distance covered by the pilot be represented by D, so that:

D = 300 x 2

   = 600 miles

iii. Thus let the distance to the starting point be represented by x. From Cosine rule, we have:

[tex]c^{2}[/tex] = [tex]a^{2}[/tex] + [tex]b^{2}[/tex] - 2abCos C

[tex]x^{2}[/tex] = [tex]500^{2}[/tex] + [tex]600^{2}[/tex] - 2(500 x 600)Cos [tex]140^{o}[/tex]

   = 250000 + 360000 - 600000(-0,7660)

   = 610000 + 459600

   = 1069600

x = [tex]\sqrt{1069600}[/tex]

  = 1034.22

x = 1034.2 miles

Using the Sine rule to determine the required internal angle, we have:

[tex]\frac{a}{Sin A}[/tex] = [tex]\frac{c}{Sin C}[/tex]

[tex]\frac{500}{Sin A}[/tex] = [tex]\frac{1034.22}{Sin 140}[/tex]

Sin A = [tex]\frac{500*0.6428}{1034.22}[/tex]

         = 0.3108

A = [tex]Sin^{-1}[/tex] 0.3108

   = 18.11

A = [tex]18^{o}[/tex]

To determine angle B, we have:

140 + 18 + B = 180 (sum of angles in a triangle)

158 + B = 180

B = 180 - 158

  = 22

B = [tex]22^{o}[/tex]

Thus, the required bearing is 180 - 22 = 158

Therefore the distance and bearing required to fly to starting point are 1034.2 miles and [tex]158^{o}[/tex] respectively.

You want to know Sandy Sellers' net weekly pay if she earns $15 per hour for 30 hours' work and has deductions of ...

Sellers' net pay will be her gross pay, less the taxes. Those taxes are all percentages of her gross pay.

  gross pay = (hourly rate) × (hours worked)

  gross pay = ($15.00/hour) × (30 hours) = $450

The deductions from her pay total ...

  12% +2.84% +6.2% +1.45% = 22.49% . . . . of her gross pay

The dollar amount of the deductions is ...

  0.2249 × $450 = $101.205 ≈ $101.21

Then Sellers' net pay is ...

  net = gross - deductions

  net = $450 -101.21 = $348.79

Sandy Sellers' take-home pay each week is $348.79.
