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.
Answer:
#5 = 6 inches
#6 = 5.8 inches
Step-by-step explanation:
The equation to find the area of a triangle is 1/2bh or 1/2 base*height.
Let’s just insert the known values.
The triangle has a base of 14 and a height of 8.2, so our equation would look like:
1/2(14)(8.2)
Now solve.
7*8.2
57.4
The triangle has an area of 57.4 mm.
Hope this helps!
