Step-by-step explanation:

See if the translation is to be one more in x value and one less in y value then mark each dot exactly to the right by one point and down by one point. Originally the n position is at -1,-1 if the x gets one more and the y gets one less it's new point would be 0,-2.

Answer:

No, since the slopes are different

Step-by-step explanation:

Parallel lines by definition have the same slope but different y-intercepts. The slope of the line  y = 6x + 9 is 6, the coefficient of x since the equation is given in slope-intercept form. Its y-intercept is 9.

For the second equation, 27x – 3y = –81 , we have to solve for y or re-write the equation in slope-intercept form;

-3y = -27x - 81

y = 9x + 27

The slope of this line is thus 9, the coefficient of x since the equation is in slope-intercept form. Its y-intercept is 27.

The two equations have different slopes and thus they are not parallel

The exact value of trigonometric function sin(15 degrees) is √6 - √2 divided by 4.

To find the exact value of sin(15 degrees), we can use the sum-to-product trigonometric identity, which states that:

sin(A) + sin(B) = 2 × sin((A + B) / 2) × cos((A - B) / 2).

In this case, we can write sin(15) as sin(45 - 30) and use the identity.

First, we have sin(45 degrees) and sin(30 degrees), which are known values of √2/2 and 1/2, respectively. Plugging these values into the identity, we get sin(15) = 2 × sin(7.5) × cos(7.5).

Now, we can use the half-angle formulas for sine and cosine to simplify further. Sin(7.5 degrees) can be expressed as (√6 - √2) / 4, and cos(7.5 degrees) as (√6 + √2) / 4. So,

sin(15 degrees) = 2 × [(√6 - √2) / 4] × [(√6 + √2) / 4], which simplifies to (√6 - √2) / 4.

In conclusion, the exact value of sin(15 degrees) is (√6 - √2) / 4. This value can be derived using trigonometric identities and the half-angle formulas for sine and cosine.

Answer:

28

Step-by-step explanation:

There are five numbers so the average must be x/5.

25= x/5

x= 125

30+29+25+20 = 104

Therefore the final number of the five must be 125-104=21

The 3 largest are still 30,29,25.

So their average is (30+29+25)/3

= 28

The average of the three larger numbers is 28

Let y be the 5th number.

Next, we shall determine the value of y. This can be obtained as follow:

Average = Sum of data / number of data

25 = (30 + 29 + 25 + 20 + y) / 5

25 = (104 + y) /5

Cross multiply

25 × 5 = 104 + y

125 = 104 + y

Collect like terms

y = 125 – 104

y = 21

Thus, the correct data are: 30, 29, 25, 20, 21

Finally, we shall determine the average of the three larger numbers.

Average = Sum of data / number of data

Average = (30 + 29 + 25) / 3

Average = 84 / 3

Average = 28

Therefore, the average the three larger numbers is 28

The range of values that we are permitted to enter into our function is known as the domain of a function.

The x values for a function like f make up this set (x). A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of values.

The range is the values of y that relation takes on, it takes on all real numbers from ( -2.5,0) to ( 0, 5 ).

The relation is a function because it passes the vertical line test.

Therefore, y = 2x+5 has y-intercept 5 and slope 2. The domain is the values of x that relation takes on, it takes on all real numbers so you have that part right.

Answer:

The cost of one bucket of popcorn is $2.75

The cost of one drink is $1.25

Step-by-step explanation:

Let

x ----> the cost of one bucket of popcorn

y ----> the cost of one drink

we know that

5x+2y=16.25 -----> equation A

3x+y=9.50

y=9.50-3x ----> equation B

Solve the system of equations by substitution

Substitute equation B in equation A and solve for x

5x+2(9.50-3x)=16.25

5x+19-6x=16.25

6x-5x=19-16.25

x=$2.75

Find the value of y

y=9.50-3x

y=9.50-3(2.75)=$1.25

therefore

The cost of one bucket of popcorn is $2.75

The cost of one drink is $1.25

Answer:

54

Step-by-step explanation:

3 tens = 3*10 = 30

24 ones = 24*1 = 24

30+24 = 54

Final answer:

The number that represents 3 tens + 24 ones is 54. This is found by adding 30 (representing the 3 tens) to 24 (representing the 24 ones).

Explanation:

The number that is the same as 3 tens + 24 ones is calculated by first understanding what each term represents.

Three tens is equivalent to 30 because one ten equals 10 and 10 multiplied by 3 equals 30.

Twenty-four ones simply means 24 because one multiplied by 24 is 24.

Therefore, to find the number that represents 3 tens + 24 ones, we add 30 and 24 together.

30 (3 tens) + 24 (24 ones) = 54

So, the number that is the same as 3 tens + 24 ones is 54.

Answer:

144.5cm^2

Step-by-step explanation:

First find area of the rectangle

Area of a rectangle = L*B

= 9*13 = 117cm^2

Now find area of the triangle

Area of triangle. = 1/2 base * height

Height = 13 - 8 =5cm

Area of the triangle = 1/2 *11 *5 = 27.4

Now area of the who figure is area of rectangle + area of triangle

= 117 + 27.5

= 144.5cm^2

For this case we have that the area of the figure is given by the area of a rectangle plus the area of a triangle.

The area of a rectangle is given by:

[tex]A = a * b[/tex]

Where a and b are the sides of the rectangle.

According to the figure we have:

[tex]a = 13 \ cm\\b = 9 \ cm[/tex]

So, the area of the rectangle is:

[tex]A = 13 * 9\\A = 117 \ cm ^ 2[/tex]

On the other hand, the area of a triangle is given by:

[tex]A = \frac {1} {2} b * h[/tex]

Where b is the base of the triangle and h the height. According to the figure we have:

[tex]b = 13-8 = 5 \ cm\\h = 11 \ cm[/tex]

Substituting:

[tex]A = \frac {1} {2} 5 * 11\\A = 27.5 \ cm ^ 2[/tex]

Adding up we have the total area is:

[tex]A_ {t} = 117 \ cm ^ 2 + 27.5 \ cm ^ 2\\A_ {t} = 144.5 \ cm ^ 2[/tex]

To find the variance, calculate the average of the squared differences between each data point and the mean. The standard deviation is found by taking the square root of the variance.

Explanation:

To calculate the variance, follow these steps:

Find the mean of the data set.

For each data point, subtract the mean and square the result.

Find the average of the squared differences.

To calculate the standard deviation, take the square root of the variance.

For example, if the data set is {2, 4, 6, 8, 10}, the mean is 6. The squared differences are {(2-6)^2, (4-6)^2, (6-6)^2, (8-6)^2, (10-6)^2}, which equals {16, 4, 0, 4, 16}. The average of the squared differences is (16+4+0+4+16)/5 = 40/5 = 8. Therefore the variance is 8. The standard deviation is the square root of the variance, so in this case, the standard deviation is √8 = 2.83.
