Solution:
Formula for calculation of 99% confidence interval is given by:
= 
P= Sample Proportion
N =Sample Size
Also,Number of voters who vote online= 19 % of 1300=19 × 13=247
Sample Population= 
=0.19
Z value for 99% confidence interval=2.58
The number of voters who vote online, who are in the 99% confidence interval for the percent of all voters who would prefer to vote online= 
So, Percent of voters , who are in the 99% confidence interval for the percent of all voters who would prefer to vote online= 100 × 0.2180 or 100 × 0.1619=21.80 % or 16.19 %
That is between, 16.19 % and 21.80 %.
→→Option (A) 19.8 % and Option (B)17.4 % are in 99 % confidence intervals.

If you were calculating it straight off of how it’s written, the answer would be 13. Using PEMDAS, the answer would be 22. I’m not sure how you’re writing it out though.
Answer:
A). y = 1/2x + 5
Step-by-step explanation:
y = 1/2x + b
5 = 1/2(0) + b
5 = 0 + b
5 = b
I believe this is the question: "Quadrilateral ABCD in the figure below represents a scaled-down model of a walkway around a historic site. Quadrilateral EFGH represents the actual walkway. ABCD is similar to EFGH. Two irregular similar quadrilaterals ABCD and EFGH are drawn. AB measures 5 inches, BC measures 4 inches, CD measures 4 inches and AD measures 3 inches. EF measures 45 feet. What is the total length, in feet, of the actual walkway?"
We should determine the ratio(proportionality) of the two similar quadrilaterals. Since AB corresponds to EF, AB=5, EF=45, we know that the side lengths of EFGH is 45/5=9 times those of ABCD. The perimeter of ABCD=5+4+4+3=16 feet, so the perimeter of EFGH, the actual pathway, is 16*9=144 feet.
