Answer: 9 because 45% of 20 is 9

Answer:

Step-by-step explanation:

First find the hourly rate Carmen makes. You can find it by dividing the amount she made by the number of hours she worked

209 / 11 = 19

Now multiply that rate by the amount of hours you want to figure out.

19 * 8 = 152

Answer: $152

Step-by-step explanation:

Divide 209 by 11 to find how much money she gets for 1 hour of work ($19) then multiply that value by 8.

The probability of flipping a coin 50 times and getting tails 22 times or fewer is given as follows:

A. 24%.

The z-score of a measure X of a normally distributed variable that has mean represented by [tex]\mu[/tex] and standard deviation represented by [tex]\sigma[/tex] is obtained by the equation presented as follows:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The parameters for the binomial distribution are given as follows:

n = 50, p = 0.5.

Hence the mean and the standard deviation are obtained as follows:

Using continuity correction, the probability of 22 or fewer tails is the p-value of Z when X = 22.5, hence:

Z = (22.5 - 25)/3.54

Z = -0.71

Z = -0.71 has a p-value of 0.2709.

Which is closest to 24%.

What are Similar Rectangles ?

Similar rectangles states that the corresponding sides are in proportion.Two rectangles are similar when the corresponding adjacent sides have the same ratio. We do not need to check the angles as all angles in a rectangle are 90 degrees.

As per the statement:

Rectangle ABCD is similar to rectangle WXYZ.

WX = 8 feet, AD = 12 feet and WZ = 16 feet.

Since. Rectangle ABCD and rectangle WXYZ are similar

then;

their corresponding sides are in proportion:

[tex]\frac{AB}{WX} =\frac{BC}{XY} = \frac{CD}{YZ} =\frac{AD}{ZW}[/tex]

To find the value of AB:

[tex]\frac{AB}{WX} =\frac{AD}{ZW}[/tex]

Substitute the given values we have;

[tex]\frac{AB}{8} =\frac{12}{16}[/tex]

Multiply both sides by 8 we have;

[tex]AB = \frac{12}{16} * 8 = 6[/tex]

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

Dhara's Lifetime earnings when she retires at the age of 65 is;  $1,901,250

The first thing we will do here is to find the difference between Dhara's current age and the age he will be when he retires. Thus;

Difference in age = 65 - 26

Difference in age = 39 years old

Bi- weekly wage = 52 weeks/2

Bi- weekly wage = 26 paychecks per annum

Thus;

Lifetime earnings = $1875.00 × 26 paychecks per annum × 39

Answer:

Step-by-step explanation:

The system of equations is y = 4x - 3 and y = -1/3x + 4 and the solution is (21/13, 45/13)

From the question, we have the table of values as the parameters that can be used in our computation:

From the table, we have

Table 1

(x, y) = (0, -3) and (4, 13)

A linear equation is represented as

y = mx + c

Where

Slope = m

c = y when x = 0

This means that

c = -3

So, we have

y = mx - 3

The point (4, 13) implies that

13 = m * 4 - 3

So, we have

4m = 16

m = 4

So, the equation is

y = 4x - 3

Table 2

(x, y) = (0, 4) and (4, 6)

A linear equation is represented as

y = mx + c

This means that

c = 4

So, we have

y = mx + 4

The point (4, 6) implies that

6 = m * 4 + 4

So, we have

4m = -2

m = -1/3

So, the equation is

y = -1/3x + 4

Substitute y = -1/3x + 4 in y = 4x - 3

-1/3x + 4 = 4x - 3

So, we have

-x + 12 = 12x - 9

Evaluate the like terms

13x = 21

Divide

x = 21/13

y = -1/3x + 4 implies that

y = -1/3 x 21/13 + 4

So, we have

y = -7/13 + 4

Evaluate

y = 45/13

So, the solution is (21/13, 45/13)

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)

Hence, the function is R(x) = (50 + 5x)(20 -x)

Answer:

  $348.79

Step-by-step explanation:

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.

Answer: To determine how much 5 inches of wire would cost at the same rate as 12 inches of wire, we can first determine the rate at which the wire is being sold by dividing the cost of the wire by the length of the wire:

36 cents / 12 inches = 3 cents/inch

We can then use this rate to determine the cost of 5 inches of wire by multiplying the rate by the length of the wire:

3 cents/inch * 5 inches = 15 cents

Therefore, 5 inches of wire would cost 15 cents at the same rate as 12 inches of wire.

It is important to note that percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100.

Since Aunt Georgia has $1000 and bought a gadget for $300, the remaining amount will be:

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.
