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.
Answer:
Step-by-step explanation:
(3/4)/(1/8)
(3/4)(8/1)
24/4
6 pieces of pipe
Let the numerator = x. Then,
The fraction is x/(3x+4).
If both the numerator and denominator are increased by 4, the fraction will be (x+4)/(3x+8), which, according to the question is equal to 9/25. So,
(x+4)/(3x+8) = 9/25
25(x+4) = 9(3x+8)
25x + 100 = 27x + 72
2x = 28
x = 14
Thus, the numerator is 14 and the denominator is (3*14 + 4), which is equal to 46. So the fraction is 14/46.
Answer:
Correct answer B
Step-by-step explanation:
Choose one point of the original rectangle In this case I chose E. I translated it 6 to the left and three down and I ended up at point M. Rotating the rectangle, the original rectangle will match up with the second rectangle.
It is most likely C if I am looking at it in need more information but if it is not C it is B
