Recall that parallel lines have the same slope.

A line parallel to y= (-3/5)x + 8 would have the same equation EXCEPT for a different constant, C, replacing that '8.'

This new line passes thru (-5,-3).  In y= (-3/5)x + C, replace x with -5 and replace y with -3.  Then:

-3 = (-3/5)(-5) + C.  Find C:

-3 = 3 + C.  Thus, C = 6


Thus, the equation of the new line is y= -(3/5)x - 6

Check:  Let x = -5 and y = -3.  Is the above equation true?

-3 = (-3/5)(-5) - 6

-3 = 3 - 6, or -3 = -3.

Using a confidence interval of proportions, it is found that the correct statement is given by:

D a confidence interval for estimating the cricket's true probability of landing on its feet is more narrow after the final 10 jumps than it was before the final 10 jumps.

<h3>What is a confidence interval of proportions?</h3>

A confidence interval of proportions is given by:

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which:

  • \pi is the sample proportion.
  • z is the critical value.
  • n is the sample size.

The margin of error is given by:

M = z\sqrt{\frac{\pi(1-\pi)}{n}}

The margin of error is inversely proportional to the square root of the sample size, hence, the higher the sample size, the narrower the interval is, hence option D is correct.

If a line is perpendicular to y=-2/3x+2, will it be perpendicular to 2x+3y=12?
vova2212 [387]

Answer:

<em>3x + 2y = -2 </em>

Step-by-step explanation:

<em>Given Equation is</em> <em>− 2 x  +  3 y  =  12</em>

3 y  = 2 x  +  12

y =  ( 2 /3 )  y  +  12

<em />

<em>Slope of this line is  </em><em>m  =  2/ 3 </em>

<em> Slope of Line A </em><em> m a  =  2 </em>

<em> Slope of Line B  </em><em>m b  =  2/ 3 </em>

<em> Slope of Line C  </em><em>m c  =  − ( 2 /3 ) </em>

<em> Slope of Line D</em>  <em>m d  =  −  ( 3 /2 ) </em>

since  m d  =  − 1 /m  ,  <em>D</em>  is perpendicular to the given line
