How to turn (3,6) and (-6,0) in to slope intercept form
1 answer:
The equation for slope-intercept form is y=mx+b. To begin, let's figure out the slope.
The slope equation is
0 - 6 / -6 - 3 = -6/-9 = 2/3
The next step is plugging it in to find b.
6 = 2/3(3) + b
Simplify both sides.
6 = 2 + b
Subtract 2 from both sides.
4 = b
Now that we have all the variables, plug in the slope (m) and b, and that should be your equation.
<h3>y = 2/3x + 4</h3>

Using the concept of y-intercept, it is found that the response that is not correct is given by:
B) Replace x with -x.
<h3>What is the y-intercept of a function?</h3>It is the value of the function when x = 0, hence it is the point (0, f(0)).
In this problem, the function is:
The y-intercept is given by:
If we just replace x with -x, we still have the same expression as above, hence the y-intercept does not change and option B is the answer to this question.

Answer:
The minimum sample size required to create the specified confidence interval is 1024.
Step-by-step explanation:
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of .
So it is z with a pvalue of , so
Now, find the margin of error M as such
In which is the standard deviation of the population and n is the size of the sample.
What is the minimum sample size required to create the specified confidence interval
This is n when .
The minimum sample size required to create the specified confidence interval is 1024.
