Answer:
n=42 adult men
Step-by-step explanation:
-The minimum sample size to get a desired margin of error, E is calculated using the formula:
-Given that 
, we can substitute to solve for n in the above formula:
Hence, the desired minimum sample size, n is 42 adult men.
Answer:
{x,y} = {-2,2}
Step-by-step explanation:
Solve equation [2] for the variable y
7y = 7x + 28
y = x + 4
Plug this in for variable y in equation [1]
-8x + 4•(x +4) = 24
-4x = 8
Solve equation [1] for the variable x
4x = - 8
x = - 2
By now we know this much :
x = -2
y = x+4
Use the x value to solve for y
y = (-2)+4 = 2
Solution :
{x,y} = {-2,2}
and this intersects at only one point so your answer is A
