\hat{p}=p\pm\frac{\sqrt{p(1-p)}}{\sqrt{n}}\\p=\frac{297}{1873}=0.1586\\ \hat{p}=0.1586\pm\frac{\sqrt{0.1586(1-0.1586)}}{\sqrt{1873}}\\=0.1586\pm\frac{\sqrt{0.1586(0.8414)}}{43.2782}}\\=0.1586\pm\frac{\sqrt{0.1334}}{43.2782}}\\=0.1586\pm\frac{0.3653}{43.2782}}\\=0.1586\pm0.0084

Please help. Explain how.

Answer:

y = \frac{4}{3} x +1

Step-by-step explanation:

1: find the perpendicular gradient - this is the negative reciprocal of the original gradient:

y=\frac{-3}{4}x+ 2 \\y=\frac{4}{3} x+c

2: Substitute in the coordinate to find the value of c:

y=\frac{4}{3}x +c\\5 = \frac{4}{3} (3) + c\\5 = 4+c\\c=1

3: Put it all together:

y=\frac{4}{3}x+1

please help. i’ve been stuck on this question the past 10 minutes i’ve tried multiple times and still don’t get it. i need help
Softa [21]

Answer:

To solve the equation, you have to to isolate the variable. So, first you subtract both sides by 7.

x +7 - 7 = -2 - 7

When you simplify further,

x = -9.

Hope this helps! :)
