Answer:We know that the dilation transformation of a figure either shrink or expand the original figure depending on the scale factor of the dilation.
As here we have scale factor=3>1.
Hence, the dilation changes the original will expand the original figure.
Hence, each of the coordinate of a figure get multiplied by 3.
Hence, the co
ordinates of the image are given as:
i.e. A(0,0) → A'(0,0)
B(2,3) → B'(6,9)
C(1,-2) → C'(3,-6)
D(-3,-3) → D'(-9,-9)

Answer:
0.7325 to 5.6675 ug/dl
Step-by-step explanation:
The middle 90% will be 45% above the mean and 45% below the mean. This means
0.5-0.45 = 0.05 and
0.5+0.45 = 0.95
We use a z table. Look in the cells; find the values as close to 0.05 and 0.95 as we can get.
For 0.05, we have 0.0505 and 0.0495; since these are equidistant from 0.05, we use the value between them. 0.0505 is z=-1.64 and 0.0495 is z=1.65; this gives us z=-1.645.
For 0.95, we have 0.9495 and 0.9505; since these are equidistant from 0.95, we use the value between them. 0.9495 is z = 1.64 and 0.9505 is z=1.65; this gives us z = 1.645.
Now we use our z score formula,
Our two z scores are 1.645 and -1.645; our mean, μ, is 3.2; and our standard deviation, σ, is 1.5:
Multiply both sides by 1.5:
Add 3.2 to each side:
2.4675+3.2 = X-3.2+3.2
5.6675 = X
Multiply both sides by 1.5:
Add 3.2 to each side:
-2.4675+3.2 = X-3.2+3.2
0.7325 = X
Our range is from 0.7325 to 5.6675.
Multiplying length times width, the area of the pool would be 1,250 square feet.
Given relation is not a function
Step-by-step explanation:
When a relation is given in the form of ordered pairs, the first element of each ordered pair is the member of domain set and second element is the member of range set.
In order for a relation to be a function, there should be no repetition in domain as the domain elements should be unique.
Given relation is:
{(1,2) (3,4) (5,8) (1,4)}
The domain is: {1,3,5,1}
As we can see there is repetition in domain i.e. 1 is twice in the set, the given relation is not a function.
Hence,
