So I guess we are solving for x here :)
So here is my work...
a=2x+6xz
Basically I think it would be
a=6xz+2x

WAIT WAIT NO I'M WRONG FORGIVE ME!

It's  x=a/2(1+3z)

Answer:

x = \dfrac{ a}{ 2+ 6z}

Step-by-step explanation:

given,

      a    =  2 x + 6 x z ..........................................(1)

to find the value of x take common from Left hand side of Equation (1)

taking common x

      a    =  ( 2  + 6  z ) x ..........................................(2)

dividing both side by ( 2  + 6  z ) in equation (2) we get

   x = \dfrac{ a}{ 2+ 6z}

hence, the answer is x = \dfrac{ a}{ 2+ 6z}

Sunny_sXe [5.5K]

Answer:  a) Required minimum sample size= 219

b) Required minimum sample size= 271

Step-by-step explanation:

As per given , we have

Margin of error : E= 5% =0.05

Critical z-value for 90% confidence interval : z_{\alpha/2}=1.645

a) Prior estimate of true proportion: p=28%=0.28

Formula to find the sample size :-

n=p(1-p)(\dfrac{z_{\alpha/2}}{E})^2\\\\=0.28(1-0.28)(\dfrac{1.645}{0.05})^2\\\\=218.213856\approx219

Required minimum sample size= 219

b) If no estimate of true proportion is given , then we assume p= 0.5

Formula to find the sample size :-

n=0.5(1-0.5)(\dfrac{z_{\alpha/2}}{E})^2\\\\=0.25(\dfrac{1.645}{0.05})^2\\\\=270.6025\approx271

Required minimum sample size= 271

Solve x;<br> x- 2 (divided by) -8 = 0<br><br> --Please Help! Due in for tomorrow! Xx

X=2
you multiply by 8 on both sides. so that your equation now looks like x-2=0
then you will add by 2 on both sides.
x=2

I would say smaller than because you would be dilating the image by a number less than 1, which is making the image smaller.
