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.

Let z = 3x+2. Then, by substitution, your equation is
.. z^2 +7z -8 = 0
_____
This equation can be factored as
.. (z +8)(z -1) = 0
.. x = -8 or +1
Then
.. 3x +2 = -8 or +1
.. 3x = -10 or -1
.. x = -10/3 or -1/3
It’s just 324 x 8 because base x height
2592cm^3
Answer:
He would pay $4,320 back
Step-by-step explanation:
If he pays $120 a month then
$120 x 12 (12 months in a year)
$1440 x 3 = $4,320
He would have to pay $1,320 extra for the car. I wouldn't be willing to buy the car.
