Answer:

2x^2 - 12*x/2= Area For Shaded Region

Step-by-step explanation:

This works because you find tha area of both and subtract the shaded area by the unshaded area

Answer: Expression for the area of shades region of the figure = 2[tex]x^{2}[/tex] - 6x

Step-by-step explanation: Area of shaded region = Area of big rectangle - Area of small rectangle

Area of rectangle = length.breadth

Area of big rectangle = 2x.x                                  { . means multiply}

                                     = 2[tex]x^{2}[/tex]

Area of small rectangle = 12.(x/2)

                                         =6x

∴ Area of shaded region = 2[tex]x^{2}[/tex] - 6x

A matrix is a rectangular array or table of numbers, symbols, or expressions, arranged in rows and columns.

The system of linear equations

-x + 5y = 7

7x - 2y = 3

Jerome saves 337.5$ on the computer.

Jerome buys the computer for 1912.5$.

The total cost of the computer is 2056$ including sales tax.

The total price of the computer not on sale is 2418.75$.

The discount is 15% of the original price:

0.15 x $2250 = $337.50.

If the sales tax is 7.5%,

The price of the computer after the discount is $2250 - $337.50 = $1912.50.

The amount of tax on the computer is 7.5% of $1912.50:

0.075 x $1912.50 = $143.44.

The total cost for the computer is the discounted price plus the tax: $1912.50 + $143.44 = $2055.94.

The total price for the computer not on sale would be the original price plus the tax:

$2250 + $169.13 = $2419.13 (where tax is 7.5% of $2250).

Answer:

C) E=118°, T=118°

Step-by-step explanation:

The angles inside a quadrilateral (shape with four sides) always add to 360°. So this means:

W+E+S+T=360°

29°+E+95°+T=360°

E+T=360°-124°=236°

Note that the shape contains two congruent triangles (they share equal sides) ΔEWS and ΔTWS. This means their angles are the same so E=T

If E=T and E+T=236°, then E=T=236°/2=118°

Answer:

C) E-118°, T=118° is the answer

The number of hours taken to have the same number of pages completed is 5 hours.

The solution to the system of equations is (5, 50).

In order to write a system of linear equations that could be used to model the situation and determine the number of hours it would take to complete the workbook, we would assign variables to the number of hours and the number of pages respectively as follows:

Next, we would translate the word problem into system of linear equations as follows:

Isaiah: y = x + 45

Brenna: y = 9x + 5

When the same number of pages are completed, the number of hours taken can be calculated as follows;

x + 45 = 9x + 5

9x - x = 45 - 5

Answer:44

Step-by-step explanation:44444444

Answer:

25%

Step-by-step explanation:

Let Dawn’s monthly allowance be 5x. Let Evelyn’s monthly allowance then be 8x.

Percentage increase by 20% is the same as multiplying a number by 1.2

To find the percentage decrease of Evelyn’s monthly allowance, we can equate their allowances after the change of their initial allowance.

1.2 * 5x = k/100 * 8x

k represents the percentage

6x = 8xk/100

Cancel the x’s from both sides

6 = 8k/100

600 = 8k

k = 75

Therefore since 75% of Evelyn’s monthly allowance is equal to Dawn’s increased monthly allowance, this means Evelyn’s monthly allowance was decreased by 25%.

Mei concluded that

We are 90% confident that the true proportion of times the die would land on the number 4 is between 0.398 and 0.562. Since this includes 0.5, the die appears to be fair.

It is based on a statistical analysis of the data collected by Mei.

The proportion of times the die landed on the number 4 is calculated as 48/100 = 0.48.

Using a statistical method called a confidence interval, we can estimate the range of values that the true proportion of times the die would land on the number 4 is likely to fall within, with 90% confidence.

The confidence interval calculated for this data is 0.398 to 0.562.

Since this interval includes the value of 0.5  (which would be the proportion of times a fair die would land on the number 4), By using statistical method we cannot reject the hypothesis that the die is fair.

Hence,

By using statistical method, we can conclude that the die would land on the number 4 is between 0.398 and 0.562 as 0.5 the die appears to be fair.

The solution of the system of equation y - 10 = 2x and 1/2 y = x + 5 is

The simultaneous equation is solved by substitution method as follows

y - 10 = 2x and

1/2 y = x + 5

Isolate y in the first equation to get

y = 2x + 10

substitute y in 1/2 y = x + 5

1/2 (2x + 10) = x + 5

x + 5 = x + 5

x = 0

substitute x = 0 into y = 2x + 10

y = 2(0) + 10

Sampling type which will yield a representative sample is stratified random sampling.

A representative sample is a subset of a population that seeks to accurately reflect the characteristics of the larger group. For example, a classroom of 30 students with 15 males and 15 females could generate a representative sample that might include six students: three males and three females.

This method uses stratified random sampling to help identify its components. Other methods can include random sampling and systematic sampling. A representative sample seeks to choose components that match with key characteristics in the entire population being examined.

Stratified random sampling is a method of sampling that involves the division of a population into smaller subgroups known as strata. In stratified random sampling, or stratification, the strata are formed based on members' shared attributes or characteristics, such as income or educational attainment.

1. To get System BBB from System AAA, we can divide both sides of the first equation in System AAA by -3:

-3x + 12y = 15

-3x/ -3 + 12y/ -3 = 15/ -3

x + 4y = -5

So System BBB is obtained by dividing both sides of the first equation in System AAA by -3.

2. Are Systems AAA and BBB equivalent?

Yes, Systems AAA and BBB are equivalent. This means that they have the same solution set, despite having different coefficients in their equations. Equivalent systems of linear equations are systems that have the same solution set, regardless of the coefficients of the equations.

The probability that it is likely that a randomly selected cookie from the batch will be a chocolate chip cookie.

Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

If P(chocolate chip) = 0.50, it means that the probability of randomly selecting a chocolate chip cookie from the batch is 0.50 or 50%.

Interpreting this probability, we can say that it is likely that a randomly selected cookie from the batch will be a chocolate chip cookie since the probability is relatively high.

Step-by-step explanation:

Let's call the number of text messages Sarah sends in a month as "x".
So, the total cost of the text messages is $0.25 * x.

The total cost of the phone service and text messages is $35 + $0.25 * x = $99.

So, $35 + $0.25 * x = $99.

Subtracting $35 from both sides, we have:$0.25 * x = $99 - $35 = $64

Dividing both sides by $0.25, we have:x = 256

So, Sarah sent 256 text messages in one month.

Step-by-step explanation:

To solve using substitution, we define one unknown variable in terms of another and sub this into a second equation with both.

We are told y=2x-8 and -3x+4y=-22, so let's sub '2x-8' in for y in -3x+4y=-22:

-3x+4y=-22

-3x+4(2x-8)=-22

-3x+8x-32=-22

5x=10

x=2

If x=2 and y=2x-8, let's sub 2 in for x to find y:

y=2x-8
