In order to answer this question, you would need to provide a coordinate, but since this question lacks that, I will explain transformations. Transformations are like moving an object throughout a room, in this case, the room is a graph. The Y coordinate
(X, Y) is moving things higher or lower, or in this case up and down the graph. The X coordinate (X, Y) is moving things forward and backwards, or left and right on the graph. So in order to find your Transformation, you need to take what was your item's original position, it's X and Y locations, and subtract from that your new location.
Here's an example, if I had a triangle with sides and corners labeled A, B, and C or for short, triangle ABC, if A is located at (1 , 0), B is located at (3 , 3) , and C is located at ( 5 , 0) what is its new transformation if it is moved up 3 and right 1?
You would then add 1 to each angle's X coordinate and add 3 to each angle's Y coordinate. Resulting in this:
A (2 , 3)
B (4 , 6)
C (6 , 3)

Answer:
x=1/2 or 0.5
B. 0.5
Step-by-step explanation:
Step one: Add x to both sides
you then get the equation 7=4x+5
Step two: subtract 5 from both sides
you then get the equation 2=4x
Divide both sides by 4 to undo the multiplication.
2/4=4x/4x
you get x=2/4 which simplifies to 1/2.
Answer:
One solution
Step-by-step explanation:
Only one solution, as the lines intersect only at (-2,2).
Answer:
The airplane is 12 ft long.
Step-by-step explanation:
If one inch is 2 feet in real life, if there are six inches, that means there are 12 feet because it is a one to two ratio. :)
Answer: a) α = 0.7927, b) at u=14.8, β = 0.99767, at u = 14.9, β= 0.2073
Step-by-step explanation: a) from the question, u= population mean = 15 and x= sample mean = 14.9
σ = population standard deviation = 0.5, n = sample size = 50.
We get the probability of committing a type 1 error by using the z score.
Z = x - u/(σ/√n)
Z = 14.9 - 15/(0.5/√50)
Z = - 0.1/0.0707
Z = - 1.41.
By checking the the probabilistic value attached to this z score using a standard normal distribution table whose area is to the left of the distribution, we have that
P(z=-1.41) = 0.7927.
Hence the probability of committing a type 1 error is 0.7927
b)
at x = 14.8 ( I let ua=x=14.8)
Z = x - u/(σ/√n)
Z = 14.8 - 15/(0.5/√50)
Z = - 0.2/ 0.0707
Z = - 2.83
Using the standard normal distribution table, we have that
P(z=-2.38) = 0.00233.
But α + β = 1
Where α= probability of committing a type 1 error
β = probability of committing a type 2 error.
β = 1 - α
β = 1 - 0.00233
β = 0.99767
At x = 14.9
Z = x - u/(σ/√n)
Z = 14.9 - 15/(0.5/√50)
Z = - 0.1/0.0707
Z = - 1.41.
P(z=-1.41) = 0.7927.
α = 0.7927.
But α + β = 1
β = 1 - 0.7927
β = 0.2073
