Answer: 1068
Step-by-step explanation:
Formula of sample size :
, where p = prior population proportion , E = margin of error , = Critical z- value.
Let p = proportion of visitors who are repeat visitors.
Given : p=0.5
E= 3%= 0.03
critical z-value for 95% confidence = 1.96
Now,
[round to the next integer]
Hence, the required sample size = 1068
The area of the model is 100.25in^2
So, letter D

Answer:
M
Step-by-step explanation:
AB was dilated by scale factor of 2 to create A'B'.
Connect points A and A' with a straight line, connect points B and B' with a straight line. The point where these two straight lines will intersect is the center of dilation.
As you can see, these lines intersect at point M, so, point M is the center of dilation.
