For this case we have that by definition, the equation of a line of the slope-intersection form is given by:

Where:
m: It is the slope of the line
b: It is the cut point with the y axis
By definition, if two lines are perpendicular then the product of their slopes is -1.
If we have: 

Thus, the equation is of the form:

We substitute the point:

Finally, the equation is:

Answer:

Using the z-distribution, it is found that the 90% confidence interval is given by: (0.6350, 0.6984).
<h3>What is a confidence interval of proportions?</h3>
A confidence interval of proportions is given by:

In which:
is the sample proportion.
In this problem, we have a 90% confidence level, hence
, z is the value of Z that has a p-value of
, so the critical value is z = 1.645.
The sample size and the estimate are given by:

Hence, the bounds of the interval are given by:


The 90% confidence interval is given by: (0.6350, 0.6984).

Answer:
add multiply divide or subtract make sure to use Pemdas then and you should have your answer
Step-by-step explanation:
Distributive Property is factors a common term by the items that are inside parenthesis.
3(2x + 5)
3 = Factor
3(2x + 5)
2x and 5 = terms
3(2x + 5)
2 = coefficient
The coefficient is the number before the variable.
