First what you do is divide 14 by 4 and you get 3.5 or 3 feet and 6 inches.
The area of a polygon equals
area = circumradius² * number of sides * sin (360 / # of sides) / 2
area = 77² * 20 * sin (360 / 20) / 2
area = 77² * 20 * sin (18) / 2
area = 118,580 * 0.30902 / 2
area =

/ 2
area =
18,321.8 square millimeters
2x+10 is less than or equal to 20
the domain is 0, 1, 2, 3, 4, 5.
Answer: 1308
Step-by-step explanation:
Given : Level of confidence = 0.97
Significance level : 
Critical value : 
Margin of error : 
If prior proportion of population is unknown , then the formula to find the population proportion is given by :-
Hence, the minimum sample size needed =1308
<span>12(X+20)=372
12X+240=372
Subtract the 240
</span>12X=372-240 ----> 12X=132
Divide by 12
12X/12=132/12 ---> x = 11
