EXPLANATION

In a isometry the distances between points are conserved, so the image of segment PQ has to have the same length as segment PQ.

When we have a translation defined by a vector the x-coordinate of the vector tells the horizontal translation and the y-coordinate the vertical translation.

For this problem, if the vector is <3, 5>, we have to translate each point 3 units to the right and 5 units up.

The endpoints of the image segment are Q'(1, 3) and P'(-1, 1)

The 2000th digit after the decimal point is 5. See the explanation below.

First, we divide the fraction to get the decimal number.

2/13 = 0.15384615384

Paying close attention, you'd notice that after the 6th number forms the decimal point, the number forms a loop that repeats again. That is:

0.153846 153846 154...

Hence, to detect the 2000th number,

we divide 2000/6

we are left with 2

(that is 333 x 6 = 1998)

Hence we count two from the decimal and that gives us the 2000th digit.

That is: 5

The approximate percentage of buyers who paid between $1925 and $2075 is; 68%

The approximate percentage of buyers who paid between $1925 and $2000 is; 34%

We are given;

Mean = $2000

Standard Deviation = $75

1) We want to find the approximate percentage of buyers who paid between $1925 and $2075

The formula that is used to calculate the z-score of a a normal distribution is;

z = (x' - μ)/σ

where;

z is z-score

x' is sample mean

μ is population mean

σ is standard deviation

For a payment of 1925;

z = (1925 - 2000)/75 = -1

For a payment of2075;

z = (1925 - 2000)/75 = 1

Thus, this is 1 standard deviation from the mean.

Thus, this is a percentage of 68%

2) We want to find the approximate percentage of buyers who paid between $1925 and $2000?

For a payment of 1925;

z = (1925 - 2000)/75 = -1

For a payment of 2000;

Explanation

Popular Problems Algebra Solve for h A=1/2h(b+B)

A= 1/2 h(b+B)

Rewrite the equation as

1/2⋅(h(b+B))=A.

1/2⋅(h(b+B))=A

Multiply both sides of the equation by 2.

2(1/2⋅(h(b+B)))=2A

Factor h out of hb+hB.

h(b+B)=2A

Divide each term in h(b+B)=2A by b+B and simplify.

We are required to determine the solution of the given equation.

This is achieved thus:

The only solution to this equation involves complex numbers. So, there is no real solution.

Hence, the answer is:

According to the exterior angle theorem, an external angle's measure is equal to the sum of its remote interior angle's two measurements. The opposite interior angles are another name for the remote interior angles. Where can I determine a triangle's outer angle? In a triangle, how can I determine the interior and outside angles?

Take the total of two interior angles of a triangle that are known and deduct it from 180 to find the internal angle of the triangle.

Simple addition of the triangle's two opposite internal angles will yield the triangle's external angle. 180° minus the inside angle equals each exterior angle. Using this formula requires the knowledge of the corresponding internal angle. Exterior angle = Total.

y = -2x + 12 is the linear equation of the line that passes through the coordinates of points (1, 10) and (2, 8).

The formula for equation of line is expressed as;

y = mx + b

Where m is slope and b is y-intercept.

The slope of a line is expressed as change in y over change in x.

Slope m = (y₂-y₁)/(x₂-x₁)

Given the data in the question;

Point 1 ( 1, 10 )

Point 2 ( 2, 8 )

First, we determine the slope of the line.

Slope m = (y₂-y₁)/(x₂-x₁)

Slope m = ( 8 - 10 )/( 2 - 1 )

Slope m = (-2)/( 1 )

Slope m = -2

Now, determine the y-intercept b, by substituting the slope and the coordinates of one point into the equation of line formula.

y = mx + b

10 = -2(1) + b

Solve for b

10 = -2 + b

b = 10 + 2

b = 12

Now that we have the slope m and y-intercept b, plug these into y = mx + b to determine the equation of the line.

y = mx + b

y = -2(x) + 12

y = -2x + 12

Therefore, the equation of the line that goes through the given points is y = -2x + 12.

Answer:

x = 8, y = 4

This can also be written as an ordered pair: (8, 4)

Step-by-step explanation:

First, set up a system of equations:

x + y = 12, $2x + $6y = $40

The first equation shows that there are a total of 12 tickets, and the other shows that the total of money for all the tickets adds to $40.

Then, solve by elimination by subtracting twice the first equation from the second to isolate y:

  2x + 6y = 40

- (2x + 2y = 24)

  0   + 4y = 16

And now we can solve for y:

4y = 16

y = 4

Then, put this back into the original equation to solve for x:

x + y = 12

x + 4 = 12

x = 8

(2.50 dollars)/(8 juice boxes) = (x dollars)/(24 juice boxes)

2.50/8 = x/24

2.50*24 = 8x

60 = 8x

8x = 60

x = 60/8

x = 7.50

----------------

Another approach:

She paid $2.50 for 8 juice boxes. The unit price is 2.50/8 = 0.3125 dollars per juice box. Multiply this by 24 to get 24*0.3125 = 7.50

----------------

Yet another method:

We know the cost for 8 juice boxes is $2.50

We want to know the cost for 24 juice boxes.

The jump from 8 to 24 is "times 3". So we'll multiply the $2.50 cost by 3 to get 3*2.50 = 7.50

We can think of it like this

[tex]\frac{2.50 \ \text{dollars}}{8 \ \text{juice boxes}}=\frac{3*2.50 \ \text{dollars}}{3*8 \ \text{juice boxes}}=\frac{7.50 \ \text{dollars}}{24 \ \text{juice boxes}}[/tex]

It should be emphasized that a connection is proportional if its graph is a line that passes through its origin.

If the graph of a connection is a line passing through the origin, the connection is proportionate. If it is not a line or ray that fails to achieve this, the ratio is not proportional.

The equation for the proportionality constant is K = y/x. This is the same equation used to get the slope of a straight line with respect to the origin.

If the graph of a connection is a line or ray that goes through the origin, the relationship is proportional. If the line or ray does not pass through the origin, it is not proportional.

Additionally, if anything is not linear, it is not proportional.

10y - 50x = 20 ___(2)

Put (1) in (2):

We have that:

50x + 20 - 50x = 20

=> 50x - 50x = 20 - 20
