Answer:
-2 and -12
Explanation:
A dilation is a transformation of a geometric image that is known to change its size not it shape.
The size of the figure basically depends on the scale factor (k).
When k >1 then there would be expansion.
When k <1 then there would be contraction.
When k=1 then no change in size
I.e for conraction the scale factor (k) must be negative
from the given options, the scale factor produce a contraction under a dilation of the original image would be -2 and -12
<h3 /><h3>Hence the correct answers are:-2 and -12 </h3>

The option that is an accurate statement about Sample Size is; A: A larger sample size is needed for increased accuracy.
<h3>What is true about Sample Size?</h3>
Sample size determination is the act of choosing the number of observations or replicates to include in a statistical sample. The sample size is an important feature of any empirical study in which the goal is to make inferences about a population from a sample.
Now, the smaller the sample size, the lesser the accuracy as you have possibility of biased research from just a handful of people. However, the larger the sample, the greater the degree of accuracy of the research.
Thus, we can say that the option that is an accurate statement about Sample Size is; A: A larger sample size is needed for increased accuracy.
Complete question is;
Which of the following is an accurate statement about sample size?
Select one:
a. A larger sample size is needed for increased accuracy.
b. A smaller sample size will reduce the size of the confidence interval.
c. Sample size is a constant percentage of the population size.
d. Sample size is independent of the confidence interval.
