a clockwise rotation 90° about the origin followed by a reflection across the y-axis
a reflection across the y-axis followed by a clockwise rotation 90° about the origin
The sequence of transformation is; B. A translation 2 units to the right and 1 unit up followed by a counter-clockwise rotation 90° about the origin.
What is the sequence of Transformation?From the given image in the transformation, we can see that the pre image which is the original image is on the right hand side while the image after transformation is on the left hand side.
Now it will be noticed that in the pre image, all the x and y coordinates are positive while the image after transformation has all the x-coordinates as negative with the y-coordinates as positive.
This transformation when critically examined is seen to be a translation 2 units to the right and 1 unit up followed by a counter-clockwise rotation 90° about the origin.

Show you work for full credit Use the SUBSITUTION method or ELIMINATION method to solve this system of equations. y = 4x and 8x + y = 18
Answer:
A. (3/2, 6)
Step-by-step explanation:
Use the substitution method:
8x + y = 18 and y = 4x
8x +4x = 18
12x = 18
x = 18/12 = 3/2
y = 4x

A regular hexagon is truncated to form a regular dodecagon (12-gon) by removing identical isosceles triangles from its six corners. What percent of the area of the original hexagon was removed
7.2 percent of the area of the original hexagon was removed
The area of hexagon is the region that lies within the sides of the hexagon. A hexagon is a two-dimensional shape that has 6 sides, 6 angles, and, 9 diagonals, and the sum of its interior angles is 720°
Area of the hexagon = (3√3 s2)/2, where 's' is the length of the side of the hexagon.
Her, We have
[tex]\(1-2s=s\sqrt3, 1=2s+s\sqrt3, 1=s(2+\sqrt3), s=\frac{1}{2+\sqrt3}\)[/tex]
Rationalize the denominator to get [tex]\(s=2-\sqrt3\)[/tex]
The area of the hexagon is [tex]\(\frac{3\sqrt3}{2}\)[/tex] and the dodecagon is [tex]\(\frac{3s^2\sqrt3}{2}\).[/tex]

What is similarity?Two objects are similar if they have the same shape, or one has the same shape as the mirror image of the other.
Given:
Using theorem
If two triangles are similar, then the ratio of the area of both triangles is proportional to the square of the ratio of their corresponding sides.
ΔSDF/Δ RTY = (SD/RT)= (DF/TY)= (FS/ YR)
ar ΔSDF² / ar ΔRTY² = 16/81
SD/ RT = 4/9
SD = 4x, RT= 9x
SD= 8
4x = 8
x = 2
So,
RT= 9*2 = 18
SF = RT -2
SF = 16
(SD/RT)= (FS/ YR)

Step-by-step explanation:
You enter a room. 2 dogs, 4 horses, 1 giraffe and a duck lie on the bed. 3 hens fly over a chair. How many legs are there on the floor?.
Answer:
28 legs are on the floor once again
There are no legs on the floor.
Hence answer is zero.
According to the question,
For 2 dogs: Each dog has 4 legs.
Therefore, 2 dogs have a total of 8 legs.
For 4 horses: Each horse has 4 legs.
Therefore, 4 horses have a total of 16 legs.
For 1 giraffe: A giraffe has 4 legs.
For 1 duck: A duck has 2 legs.
For 3 hens: Each hen has 2 legs.
Therefore, 3 hens have a total of 6 legs.
To get the total number of legs on the bed,
we simply add up all the legs of the animals on the bed,
⇒ 8 legs + 16 legs + 4 legs + 2 legs + 6 legs = 36 legs.
Now, to get the number of legs on the floor,
We need to subtract the number of legs on the bed from the total number of legs of all the animals,
For 2 dogs with a total of 8 legs.
For 4 horses with a total of 16 legs.
For 1 giraffe with 4 legs.
For 1 duck with 2 legs.
For 3 hens with a total of 6 legs.
So, the total number of legs of all the animals is,
⇒ 8 legs + 16 legs + 4 legs + 2 legs + 6 legs = 36 legs.
Since all the animals are on the bed,
There are no legs on the floor.
Therefore, the answer is 0 legs on the floor.

When you win 25% of the time based on the probability, this illustrates that the number of products picked will be 7 products.
How to illustrate the probability?Based on the information given, the following can be depicted. It should be noted that there are 6 sides as well as 4 cards.
Therefore, the numbers on the dice i.e from 1 - 6 will be represented 4 times each. This gives a total of (4 × 6) = 24. There are also 4 cards. The total in sample space will now be:
= 24 + 4 = 28
The frequency table will be such that 28 or more have a relative frequency of 9. Therefore, the probability that a person wins the game will be:
= 9/28 = 32.1%
When you win 25% of the time, this illustrates that the number of products picked will be:

Answer:
Experimental Probability = 1/3
Theoretical Probability = 1/6
========================================================
Explanation:
Count how many times the number "2" shows up in the "Result" column. There are 4 instances of this value. This is out of 12 trials total.
Divide the two numbers to get 4/12 = 1/3 as the experimental probability
-------------
In contrast, the theoretical probability is 1/6 because there's 1 side labeled "2" out of 6 sides total.
The decimal form of each fraction is:

∴
The value of the x will be equal to 1.
What is the Pythagorean theorem?The section of the zoo is a right triangle. The new path is in front of the right angle, therefore it is the hypotenuse. To find the length of the hypotenuse we use the Pythagorean theorem:
H² = P² + B²
Given that the hypotenuse is of length 2 and legs of length x+1 and x-1. The value of x will be calculated as:-
H² = P² + B²
2² = ( x + 1 )² + ( x - 1 )²
4 = ( x² + 2x + 1 ) + ( x² - 2x + 1 )
4 = 2x² + 0 + 2
4 - 2 = 2x²
x = √1 = ±1
x = 1 and x = -1 ignore negative value.

Answer:
60 degrees
Step-by-step explanation:
Since all three sides are the same length, all three angles must be the same size. This means the triangle is an equilateral triangle
The angles are 60 degrees
Answer:
Hello! The answer is 60°.
Step-by-step explanation:
As marked by the dashes on each side, the sides are congruent. If the sides are congruent, this means that the angle measures are equal.
Having three equal sides is an equilateral triangle, and the total angle measure sum is 180.
To find the measure of angle y, you will have to divide the total angle measure by the number of angles:

The probability that the mean weight of the sample babies would be less than 3631 grams is 0.1591 or 15.91%.
The mean weight of the babies (μ) = 3685 grams.
The variance (σ²) = 330625.
Therefore, the standard deviation (σ) = √330625 = 575.
The sample size (n) = 113.
The sample mean = μ - 3685 grams.
The sample standard deviation (s) = σ/√n = 575/√113 = 54.09145.
We are asked to find the probability that the mean weight of the sample babies is less than 3631 grams, that is,
P(X < 3631) = P(Z < {(3631 - 3685)/54.09145})
Using the formula: Z = (x - μ)/s,
or, P(Z < -0.9983) = 0.1591 or 15.91%.
From the table of area under the z-score.
P(X < 3631) can also be calculated using calculator function:
Normalcdf(-100000000,3631,3685,54.0195), which gives the value 0.1591 or 15.91%.

Answer:

Step-by-step explanation:
x + y = 5
xy = 6
Solve the first equation for x.
x = 5 - y
Substitute 5 - y for x in the second equation.
xy = 6
(5 - y)y = 6
5y - y² = 6
y² - 5y + 6 = 0
Factor.
(y - 2)(y - 3) = 0
y - 2 = 0 or y - 3 = 0
y = 2 or y = 3
Now substitute 2 for y in the first equation and solve for x.
x + y = 5
x + 2 = 5
x = 3
One solution is x = 3; y = 2, or (3, 2).
Now substitute 3 for y in the first equation and solve for x.
x + y = 5
x + 3 = 5
x = 2
Another solution is x = 2; y = 3, or (3, 2).
