Answer:

8x + 3y = -47

Step-by-step explanation:

1. Use the y = mx + b form to find b:

$y=-\frac{3}{8} x+b\\-4=\frac{3}{8}(5)+b\\-32=15+8b\\-47=8b\\-\frac{47}{8} =b$

2. Plug in b for the new equation:

$y=-\frac{3}{8} x-\frac{47}{8}$

3. Get rid of the denominators and simplify everything into standard form

(ax + by = c)

$y=-\frac{3}{8} x-\frac{47}{8}\\8y=-3x-47\\3x+8y=-47$

4(p+1.25)=725
divide by 4
p+1.25= 131.25
subtract 1.25 both sides
p = 130

Answer: (0.685, 0.735)

Explanation:

First, we will compute the confidence level of the given:

$\text{ Confidence Level }=\frac{36}{40}\times100\%=90\%$

They gave us a margin of error of 0.025. From the given, we know that p=71%=0.71.

The confidence interval would then be:

$\begin{gathered} (p-E,p+E) \\ =(0.71-0.025,0.71+0.025) \\ =(0.685,0.735) \end{gathered}$

Therefore, the confidence interval would then be (0.685, 0.735)
