The 2 number shape which is 90ﾟcounterclockwise rotation about the origin and 180° rotation about the origin.
What are transformations?
A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure. The original shape of the object is called the Pre-Image and the final shape and position of the object is the Image under the transformation.
Given:
After rotation in sequence we will get 2 number shape which is congruent shape.
According to given question we have
A 90ﾟcounterclockwise rotation about the origin : means a right angle about the origin in opposite direction the needle would point to (9=45 mins)the reflection of it would mean the needle is at 3 = 15 min.
180° rotation about the origin : either in the clockwise or counterclockwise direction, each point of the given figure has to be changed from (x, y) to (-x, -y) .
Therefore, the 2 number shape which is 90ﾟcounterclockwise rotation about the origin and 180° rotation about the origin.

The distance Train A travels is represented by d = 69t, where d is the distance in kilometers and t is the time in hours. The distance Train B travels at various times is shown in the table. What is the unit rate of each train? Which train is going faster?
If d is distance measured in km and t is time measured in hours, then d = 69t tells you that train A is moving at a rate of 69 km/h.
Why? If t = 1, then d is the distance it moves in 1 hour, and that's precisely the unit rate. It's the rate at which the distance changes when 1 unit of time passes.
For train B, use the info in the given table. In 1 hour (between hours 4 and 5), the train covers a distance of 375 km - 300 km = 75 km. So it's moving at a rate of 75 km/h.
It should be clear which train is faster.
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
[tex]d(A) = 69t[/tex]
[tex]d(B) = 75t[/tex]
The unit rate is the coefficient of t which is the slope of the line because the trains distance traveled equation are linear.
Thus :
Train A's unit rate is 69 km per hour.
And
Train B's unit rate is 75 km per hour.
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
Train B is going faster because its unit rate is greater than Train A's unit rate .

What is the value of x?
Enter your answer in the box.
x = ____
Answer:
X=32
Step-by-step explanation:
since it is equilateral, all the angles are the same so they equal 60 , because those are the only possible angle measurements that an equilateral triangle can have.
we know that all the angles are equal to 60 so we set up an equation
2x-4=60

O A 2.200
O B. 2,500
OC. 2,300
OD. 2,400
you’ve have by the end of today (12am)
Answer:
B. 2,500
Step-by-step explanation:
The diagram of the area of the store has been divided A and B as shown in the attachment below.
Dimensions of A:
(*Note: scale = 1 in to 16 ft)
Length = 4 inches
Actual length = 4*16 = 64 ft
Width = 1¾ inches
Actual width = 1¾*16 = 28 ft
Area of A = length * width = 64*28 = 1,792 ft²
Dimensions of B:
(*Note: scale = 1 in to 16 ft)
Length = 2¼ inches
Actual length = 2¼*16 = 36 ft
Width = 3 inches - 1¾ inches = 1¼ inches
Actual width = 1¼*16 = 20 ft
Area of A = length * width = 36*20 = 720 ft²
Area of the store = area of A and area of B = 1,792 + 720 = 2,512 ft²
Approximately, the are is 2,500 ft²

The number of road construction projects that take place at any one time in a certain city follows a Poisson distribution with a mean of 3. Find the probability that exactly four road construction projects are currently taking place in this city.
Answer:
The probability that exactly four road construction projects are currently taking place in this city is 0.168.
Step-by-step explanation:
Let X denote the number of road construction projects that take place at any one time in a certain city.
It is provided that X follows a Poisson distribution with parameter λ = 3.
Then the probability mass function of X is:
[tex]p_{X}(x)=\frac{e^{-\lambda}\cdot \lambda^{x}}{x!};x=0,1,2,3...[/tex]
Compute the probability that exactly four road construction projects are currently taking place in this city as follows:
[tex]P(X=4)=\frac{e^{-3}\cdot 3^{4}}{4!}[/tex]
[tex]=\frac{0.04979\times 81}{24}\\\\=0.16804125\\\\\approx 0.168[/tex]
Thus, the probability that exactly four road construction projects are currently taking place in this city is 0.168.
Using the Poisson distribution, it is found that there is a 0.1954 = 19.54% probability that exactly four road construction projects are currently taking place in this city.
We have only the mean for the discrete distribution, hence, the Poisson distribution is used.
Poisson distribution In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by:[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]
The parameters are:
x is the number of successes e = 2.71828 is the Euler number [tex]\mu[/tex] is the mean in the given interval.In this problem, the mean is of 3, hence [tex]\mu = 3[/tex].
The probability that exactly four road construction projects are currently taking place in this city is P(X = 4), hence:
[tex]P(X = 4) = \frac{e^{-3}3^{4}}{(4)!} = 0.1954[/tex]
0.1954 = 19.54% probability that exactly four road construction projects are currently taking place in this city.

Coliform bacteria are distributed in a river at an average concentration of 1 per 20 cc of water. If we draw from the river a test tube containing 10cc of water, what is the probability that the sample contains exactly 2 coliform bacteria
Answer:
0.5
Step-by-step explanation:
Given that: An average concentration of 1 coliform bacteria per 20 cc of the river water.
This implies that in 20 cc of the water, it is certain that 1 coliform bacteria would be found. So that:
pr(1 bacteria in 20 cc of water) = 1
i.e the probability of getting 1 bacteria in 20 cc of water is 1.
The probability of the 10 cc sample of water containing 2 coliform bacteria can be determined as:
pr(2 bacteria in 10 cc of water) = [tex]\frac{1}{2}[/tex]
= 0.5
Jordan and Micheal are planing a graduation party with 45 guests. They want to seat an equal number of guests at each table.Each table should have more than one guest.List te different ways the guests and tables could arranged. Tell how many tales are needed for each group of guests. guests at each table.Each table should have more than one guest.List different ways the guests and tables
Answer:9 tables with 5 people at each one
Step-by-step explanation:
Using the factorization that defines the arrangement, there can be 9 tables for 45 guests with 5 guests per table. "A large number is factorised, which is the process of breaking it down into smaller numbers that, when multiplied together, produce the original number. A number is factorised when it is divided into its factors or divisors."
What is factorization?The breaking or decomposition of an entity (such as a number, a matrix, or a polynomial) into a product of another entity, or factors, whose multiplication results in the original number, matrix, etc., is known as factorization or factoring in mathematics. The Grouping method, the Difference in Two Squares, the Sum or Difference in Cubes, and the Greatest Common Factor (GCF) are the four main methods of factoring. Divide a number by the smallest prime number (larger than 1) that divides it evenly and leaves no remainder to find its factors quickly. As you receive more numbers, repeat this procedure until you reach 1.
Here,
