Answer:
17.98 square meters
Step-by-step explanation:
find the area of rectangle
length x width
6.2x1.8= 11.16
find area of triangle
base x height x 1/2
base= 6.2
height= 4-1.8= 2.2
area=2.2 x 6.2 x 1/2 = 6.82
add both together to get area of figure
6.82 + 11.16 = 17.98
Answer: we need to survey 2285 Americans.
Step-by-step explanation:
When population proportion (p) is known, then the formula to evaluate the sample size( minimum) is given by :-
, where E = margin of error , z* = critical z-value.
Given: p= 0.61, E=0.02, Critical z value for 95% = 1.96
Required sample size: 
Hence, we need to survey 2285 Americans.
I believe it would be -4/3.
13/4 =12/4 +1/4=3+1/4 so it has to be between 3 and 4 on the number line.Hope this helps and thank you for letting me help you ✅
Angle 1 and 2 are vertical angles
Hope this helps :)
