Use the calculator to find the Product
Answer: a) 683 b) 1067
Step-by-step explanation:
The confidence interval for population proportion is given by :-

a) Given : Significance level :
Critical value : 
Margin of error : 
Formula to calculate the sample size needed for interval estimate of population proportion :-

Hence, the required sample size would be 683 .
b) If no estimate of the sample proportion is available then the formula to calculate sample size will be :-

Hence, the required sample size would be 1067 .
divide 63 by9
63 / 9 = 7
each piece is 7 meters long
Mapping T'U'V'W' onto TUVW is just the backwards translations of TUVW to T'U'V'W'.
The translation (x + 3, y - 3) moves all x-coordinates 3 units to the right and all y-coordinates 3 units down.
So if we want to move the figure back to its original position, we do the opposite: move all x-coordinates 3 units to the <em>left</em> and y-coordinates 3 units <em>up</em>.
This is expressed as (x - 3, y + 3).
