Given:

The point is B(2,5) and its image is B'(1,2.5).

To find:

The scale factor.

Solution:

If a figure is dilated by the scale factor k and (0,0) is the center of then the scale factor is defined as

[tex]k=\dfrac{\text{x-coordinate of the point on image}}{\text{x-coordinate of the corresponding point on the original figure}}[/tex]

x-coordinate of point B' is 1 and the x-coordinate of point B is 2. So, the scale factor is

[tex]k=\dfrac{1}{2}[/tex]

Therefore, the scale factor is  [tex]\dfrac{1}{2}[/tex] and the correct option is D.

Answer:

12 to 15 ratio of girls to boys

Answer:

Option B

Step-by-step explanation:

Option A, C and D have x- values that repeat and you cannot have that.

Y values can repeat but not x-values.

Option B has all x values with different y-values

Answer:

B.

Step-by-step explanation:

an output can have more than one input but an input can only have one output

basically only one arrow can go from the input to the output and b is the only one who's graph thing is like that

Answer: Samples A and B have the same mean, but Sample A has a larger median then Sample B.

Step-by-step explanation:

The median is the middle number in the sequence.

To find the median, place the numbers in order. Then take away, or cross out, one number from each side. Keep going until you are down to one or two numbers. If there is only one number left, that’s your median. If two, add the numbers together and divide by 2.

The mean is the average. To get the mean you add up all the values and subtract that sum by how many numbers there are in the sequence.

Option D is correct for the given conditions, Samples A and B have the same mean, but Sample A has a larger median than Sample B.

The descriptive summary of a data set is known as the central tendency in statistics. It reflects the center of the data distribution through the use of a single number from the dataset. Additionally, it only provides a summary of the dataset rather than information on specific data within the dataset. In general, several statistical metrics can be used to determine a dataset's central tendency.

Given  the data sets of two sets of quiz scores,

Sample A = 5, 5, 5, 5, 5

sample B = 2, 2, 2, 2, 17

mean is the average of total samples,

mean of sample A = (5 + 5+ 5 + 5 + 5 )/5

mean of sample A = 5

Mean of sample B = (2 + 2 + 2+ 2 + 17)/5

mean of sample B = 5

since the mean of both sample are same,

median is the central digit of sets

median of A is 5 and the median of B is 2,

so the median of sample A is larger than sample B.

Hence option D is correct.

Answer:

x= -9/4

Step-by-step explanation:

1) Isolate X

2) This will give you x+15x+4x=-21-24

(moving terms to another side will make it opposite, in this case positive 24 moving to the right will become negative 24)

3) Add the like terms

x+15x+4x = 20x

-21-24= -45

this will give you 20x=-45

4)Find the value of X by moving the 20 multiplier to the other side (this will become the opposite, division of 20)

x= -45/20

5) Simplify your answer

= -9/4

brainlyst pls I think I spelt is wrong

Step-by-step explanation:

When a line or shape or point is rotated, it must be rotated around a point.

The image of the point is D. (3,4)

The point is given as:

[tex]\mathbf{(x,y) = (-3,-4)}[/tex]

A 180-degree rotation across the origin is represented as:

[tex]\mathbf{(x,y) \to (-x,-y)}[/tex]

Substitute values for the coordinates of the point (x,y)

[tex]\mathbf{(-3,-4) \to (-(-3),-(-4))}[/tex]

Simplify

[tex]\mathbf{(-3,-4) \to (3,4)}[/tex]

Hence, the image of the point is D. (3,4)

The graph formed by equation y= -2/3x+10 will be perpendicular to the graph by equation y=3/2x-10.

A line in the form of ax + by + d = 0 will be a linear equation and if we convert it into the form of y = mx + c where m will be the slope of that equation.

If two lines are perpendicular to each other then the product of their slope of them will be (-1).

⇒  m₁ ₓ m₂ = -1

The slope of line 2x + 3y = 10 will be -2/3

To be any line perpendicular whose slope m with the 2x + 3y = 10

⇒ -2/3 × m = -1

⇒   m = 3/2 so the slope of that line should be 3/2

Hence, line y=3/2x-10 will be perpendicular to the 2x + 3y = 10.

Answer:

37.6 in

48.2 yd

Step-by-step explanation:

The are of a circle is given as :

Area = pi(d²) /4

Area = 1110.4in²

1110.4 = 3. 14 * d² / 4

1110.4 * 4 = 3.14 * d²

4441.6 = 3.14d²

d² = 4441.6 /3.14

d² = 1413.8051

d = 37.600

d = 37.6

8.)

Area, A = 1824.7yd²

1824.7 = 3. 14 * d² / 4

1824.7 * 4 = 3.14d²

7298.8 = 3.14d²

d² = 7298.8 / 3.14

d² = 2323.2801

d = sqrt(2323.2801)

d = 48.200

Hence, diameter = 48.2 yd

x=-4     y=-7

Step-by-step explanation:

-4x+y=9     get y alone

add 4x both sides

y=2x+1

y=2(-4)+1

y=-8+1

y=-7

Answer:

20 is 80 of 25

Explanation:

20x10/8=25

A percentage is a way to describe a part of a whole. 20 is 80% of 25.

A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

Let the number be x. Therefore, we can write,

80% of x = 20

0.80 × x = 20

x = 20/0.8

x = 25

Hence, 20 is 80% of 25.
