Answer:
2 proportions z test
The two populations are named as residents from the first county and residents from the second county.
Step-by-step explanation:
This is testing hypothesis about the difference between two proportions.
When the proportions are tested if they are the test statistic
z= ( p^1-p^2)- (p1-p2) / √p₁q₁/n₁ + p₂q₂/ n₂
where p^1 is the proportion of success in the first sample and p^2 of size n₁ is the proportion of success in the second sample of size n₂ with unknown proportions of successes p1 and p2 respectively.
When the sample sizes are sufficiently large
z= ( p^1-p^2)- (p1-p2) / √p₁q₁/n₁ + p₂q₂/ n₂ is approximately standard normal.
The two populations are named as residents from the first county and residents from the second county.
The factor of 100x to the power of 2 power -9 is 2.
The value of "x" is 
<em><u>Solution:</u></em>
Given f(x) = 4x - 6
g(x) = 8x + 4
<em><u>To find: value of x when f(x) = g(x)</u></em>
We can equate f(x) and g(x) as per given statement and solve for x
f(x) = g(x)
<em><u>Substituting the values of f(x) and g(x) in above expression,</u></em>
4x - 6 = 8x + 4
4x - 8x = 4 + 6
-4x = 10
On solving,
Thus value of "x" is
