Remember what a standard form equation is. ⇩
Y= mx+ b
Know what this means for your equation⇩
M is the slope and b is the y intercept
Apply this to your equation ⇩
-1/2 is the slope and -4 is the y intercept
How to graph it?⇩
Start by plotting your first point on your y intercept of -4. Then apply rise/run. Since your equation is negative go up 1 and to the left 2. (negative goes to the left and positive to the right) Graph is put above

Answer:
<h2>(f/g)(x) = 3</h2>Step-by-step explanation:
f(x) = 9x + 3
g(x) = 3x + 1
To find (f/g)(x) divide f(x) by g(x)
That's
Factorize f(x)
f(x) = 9x + 3 = 3(3x + 1)
So we have
Simplify
We have the final answer as
<h3>(f/g)(x) = 3</h3>Hope this helps you
Using the z-distribution, it is found that the 95% confidence interval is (0.46, 0.526), and it does not provide strong evidence against that belief.
<h3>What is a confidence interval of proportions?</h3>A confidence interval of proportions is given by:
In which:
is the sample proportion.
- z is the critical value.
- n is the sample size.
In this problem, we have a 95% confidence level, hence, z is the value of Z that has a p-value of
, so the critical value is z = 1.96.
We have that a random sample of 864 births in a state included 426 boys, hence the parameters are given by:
Then, the bounds of the interval are given by:
The 95% confidence interval estimate of the proportion of boys in all births is (0.46, 0.526). Since the interval contains 0.506, it does not provide strong evidence against that belief.
