Answer: stars

Step-by-step explanation: if every 5th row has moons, then only the rows that are multiples of 5 have moons such as row 5, row 10, row 15 etc. since every other row has stars and 24 isn’t a multiple of 5, row 24 has stars :)

Answer:

Step-by-step explanation:

First row has moons, every fifth has moons. Therefore, 1, 6, 11, 16, 21, 26.

When the scale factor of the map is less than 1, then the location will be above the map projection plane

The scale factor is used in the UTM mapping systems.

UTM stands for Universal Transverse Mercator, it is the coordinate grid used for the map projection.

The scale factor is an important part in the UTM mapping. Because it is used to show the distortion from the mapping system. Distortion is because of the Earth is mapped into flat surface.

So we can divide the surface into two, the surface above the mapping projection and the surface below the mapping projection

If the scale factor is less than 1 the location will be above the map projection plane and if the scale factor is greater than 1 the location will be below the map projection plane

Therefore, the scale factor less than 1 shows the location above the projection

The ordered pair which does not satisfy the equation f ( x ) = ( 1/2 ) x - 7 is

A ( 2 , 8 )

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation be represented as A

Now , the value of A is

f ( x ) = ( 1/2 ) x - 7

The value of f ( x ) = y

So , the ordered pair will be of the point A ( x , y )

a)

( 1 , -6 1/2 )

The value of the point A ( x , y ) = A ( 1 , -6 1/2 )

So , the equation is f ( x ) = ( 1/2 ) x - 7

Substitute the value of x and y in the equation , we get

y = ( 1/2 ) x - 7

-6 1/2 = ( 1/2 ) 1 - 7

-6 1/2 = 1/2 - 7

-6 1/2 = -6 1/2

Therefore , the ordered pair A ( 1 , -6 1/2 ) satisfies the equation

b)

( 2 , 8 )

The value of the point A ( x , y ) = A ( 2 , 8 )

So , the equation is f ( x ) = ( 1/2 ) x - 7

Substitute the value of x and y in the equation , we get

y = ( 1/2 ) x - 7

8 = ( 1/2 ) 2 - 7

8 = 1 - 7

8 ≠ -6

Therefore , the ordered pair A ( 2 , 8 ) does not satisfy the equation

c)

( -2 , -8 )

The value of the point A ( x , y ) = A ( -2 , -8 )

So , the equation is f ( x ) = ( 1/2 ) x - 7

Substitute the value of x and y in the equation , we get

y = ( 1/2 ) x - 7

-8 = ( 1/2 ) ( -2 ) - 7

-8 = -1 - 7

-8 = -8

Therefore , the ordered pair A ( -2 , -8 ) satisfies the equation

d)

( 0 , -7 )

The value of the point A ( x , y ) = A ( 0 , -7 )

So , the equation is f ( x ) = ( 1/2 ) x - 7

Substitute the value of x and y in the equation , we get

y = ( 1/2 ) x - 7

-7 = ( 1/2 ) ( 0 ) - 7

-7 = 0- 7

-7 = -7

Therefore , the ordered pair A ( 0 , -7 ) satisfies the given equation

Hence , the ordered pair A ( 2 , 8 ) does not satisfy the equation

To enlarge a figure by scale factor of 1 , multiple the coordinates of pre-image by 1 though scale factor 1 won't affect anything .

Scale factor is a number by which the size of any geometrical figure or shape can be changed with respect to its original size. It is the ratio of the sizes of the original figure with the dilated figure.

The scale factor can either increase the size of an object or decrease the size of an object.

The basic formula:

Scale factor = Dimension of the new shape ÷ Dimension of the original shape.

Enlarging a shape means to change its size. To enlarge a shape, multiply all lengths of the shape by the scale factor. The scale factor tells us how many times larger the shape will be.

When the scale factor is 1 , a copy of a pre-image form . No, change in the image will happen . You will produce you an original image.

Answer:

Step-by-step explanation: No f(x) is not an inverse of g(x)

Answer:

The correct values for points A, B, C, and D on a number line going from negative 2 to positive 2 in increments of 1 are:

A = negative 2

B = negative 3/4

C = negative 1/4

D = 1/4

This can be determined by noting that each mark on the number line represents a distance of 1/4, and by counting the number of marks to the right or left of the given points. For example, point B is 1 mark to the right of negative 2, which means it is located at negative 2 + 1/4 = negative 3/4. Similarly, point C is 1 mark to the left of negative 1, which means it is located at negative 1 - 1/4 = negative 1/4. The other points can be determined in the same way.

AAA is not a congruence shortcut.

SSS, SAS, ASA, and AAS are the four shortcuts that let students know that two triangles must be congruent.

Two figures are considered to be "congruent" if they can be positioned precisely over one another.

Both of the bread slices are the same size and shape when stacked one on top of the other.

Congruent refers to things that are exactly the same size and shape. Even if we flip, turn, or rotate the shapes, the shape and size should remain the same.

AAA is not a congruence shortcut we can easily proof.

An angle is formed when two straight lines or rays meet at a single terminal.

The place where two points converge is known as an angle's vertex.

The name "angel" comes from the Latin word "angulus," which means "corner."

Angles are also produced when two planes intersect.

These are what are known as dihedral angles.

So, according to the given figure of the diagram:

The probability of the given event is 1/9.

The odds against the event are 8 to 1.

What is probability?

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a proposition is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

When we roll 2 dice, then

Sample space i. e possible outcomes are

{(1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (1, 5), (1, 6),

(6, 1), (6, 2), (6, 3), (6, 4), (6, 5), (6, 6)}

n(S) = 36

Let A be the event of getting a total of 5.

Therefore,

A = {(1, 4), (2, 3), (3, 2), (4, 1)}

⇒ n(A) = 4

⇒ P(A) = Probability of A = n(A) / n(S) = 1 / 36 = 1/9

(a) Probability of given event = 1/9

(b) Odds against the event = 1- P(A) / P(A)

                                             = (1 - 1/9) / (1/9)

                                             = (8/9) / (1/9)

                                             = 8/9 x 9/1

  Odds against the event    = 8/1

The reduced odds against the event are 8 to 1.
