How do I use elimination process when solving two variable equations?

kenny6666 [7]

Solve simultaneously:

<span>15x-8y=52 and
6x+14y=38
</span>
Let's solve this system thru elimination by addition/subtraction:

Let's get rid of the x terms.
To do this, mult. the first eqn. by -6 and the second by 15. (This is not the only way in which we can do this!!) We get

-90x + 48y = -312
90x +210y = 570
--------------------------
Add all 3 columns together. We end up with:

258y = 258, so y = 1. You can find x by subst. 1 for y in either of the given equations.

If you'd like more help, please be specific about what you want.

In a poll conducted by the Gallup organization in April 2013, 48% of a random sample of 1022 adults in the U.S. responded that t

Answer: 95% confidence interval would be (0.449, 0.511)

Step-by-step explanation:

Since we have given that

n = 1022

p = 48% = 0.48

We need to find the 95% confidence interval first.

z = 1.96

Margin of error would be

$z\sqrt{\dfrac{p(1-p)}{n}}\\\\=1.96\times \sqrt{\dfrac{0.48\times 0.52}{1022}}\\\\=0.031$

95% confidence interval would be

$p\pm 0.031\\\\=(0.48-0.031,0.48+0.031)\\\\=(0.449,0.511)$

It means true proportion who felt that economic growth is more important than protecting the environment is within 0.449 and 0.511 using 95% confidence.
