Answer:

  y +2 = 2(x +3)

Step-by-step explanation:

The equation in point-slope form for a line with slope m through point (h, k) is ...

  y -k = m(x -h)

The slope of your given line is the coefficient of x, -1/2. The slope of a perpendicular line will be the negative reciprocal of that: -1/(-1/2) = 2. So, you have m = 2, (h, k) = (-3, -2), and your desired equation is ...

  y -(-2) = 2(x -(-3)) . . . . . . which can be simplified to ...

  y +2 = 2(x +3)

Determine the value(s) for which the rational expression 2x^2/6x is undefined. If there's more than one value, list them separat
Dmitry [639]

Answer:

0

Step-by-step explanation:

Hello, dividing by 0 is not defined. so

\dfrac{2x^2}{6x}

is defined for x different from 0

This being said, we can simplify by 2x

\dfrac{2x^2}{6x}=\dfrac{2x*x}{3*2x}=\dfrac{1}{3}x

and this last expression is defined for any real number x.

Thank you

The margin of error given the proportion can be found using the formula

z* \sqrt{ \frac{p(1-p)}{n} }

Where
z* is the z-score of the confidence level
p is the sample proportion
n is the sample size

We have
z*=2.58
p=0.38
n=80

Plugging these values into the formula, we have:
2.58 \sqrt{ \frac{0.38(1-0.38)}{80} } =0.14

The result 0.14 as percentage is 14%

Margin error is 38% ⁺/₋ 14%
