Answer:
(2, 0 )
Step-by-step explanation:
To find the x- intercept let y = 0 in the equation and solve for x, that is
8x - (0) = 16, that is
8x = 16 ( divide both sides by 8 )
x = 2 ← x- intercept ⇒ (2, 0 )
Answer:
12
Step-by-step explanation:
A compound interest equation is represented as A = P(1 + r/n)^nt, where n=the number of times per year the interest is compounded. In the given equation, n=12.

Answer:
The margin of error for the 95% confidence interval used to estimate the population proportion is of 0.0209.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.
In which
z is the z-score that has a p-value of .
The margin of error is of:
In a clinical test with 2161 subjects, 1214 showed improvement from the treatment.
This means that
95% confidence level
So , z is the value of Z that has a p-value of , so .
Margin of error:
The margin of error for the 95% confidence interval used to estimate the population proportion is of 0.0209.
