<u>Answer in picture.</u>
Answer/Step-by-step explanation:
When the scale factor of a dilation is less than one, the dilation is a reduction. Corresponding sides in similar figures must be proportional. Dilations of an angle are congruent to the original angle. Dilation (scaling) does not affect angle measure. It remains the same. That is, an image of an angle transformed by scaling is an angle of the same measure as an original.
Dilations always increase the length of line segments. If a shape is dilated, the angles remain the same. Dilations increase the measure of angles in a shape. Dilations of a triangle are similar to the original triangle.
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.
Dilation is the increase or decrease in size of an object by a factor k. If k > 1, it is an enlargement but if k < 1, it is a decrease. Dilation preserves the orientation of an object but changes the size.

Answer: 554
Step-by-step explanation:
If prior population proportion is known, then the formula to find the sample size is given by :-
As per given description, we have
p= 0.1
E=0.025
Critical z-value for 95% confidence :
Then,
Hence, the minimum sample size required = 554.
