Y equals thirty two divided by two to the x power
y=32/(2^x)
I don't know how to put this into the form you needed, because I don't think that is possible, but perhaps the first blank is 32 the second is 1 and the third is 2 to the power of x

19. 4x-y+2z =<br> 8x+y-4<br> Find x

Varvara68 [4.7K]

Answer:

x = $\frac{4-2y+2z}{4}$

Step-by-step explanation:

4x-y+2z = 8x+y-4

4x-8x-y+2z = 8x - 8x +y-4

-4x -y +2z= y-4

-4x -y+y +2z = y+y-4

-4x +2z = 2y-4

-4x+2z-2z = 2y-2z-4

-4x = 2y-2z-4

$x= \frac{2y-2z-4}{-4}$ = $\frac{4-2y+2z}{4}$

Claim: Most adults would not erase all of their personal information online if they could. A software firm survey of 677 random

Alika [10]

Answer: The value of test statistic is -0.052.

Step-by-step explanation:

Since we have given that

n = 677

and

$\bar {p}=0.499$

Claim that Most of the adults erase all of their personal details online.

p = 0.5

q = 1-0.5 = 0.5

So, the test statistic would be

$z=\dfrac{\bar{p}-p}{\sqrt{\dfrac{pq}{n}}}\\\\z=\dfrac{0.499-0.5}{\sqrt{\dfrac{0.5\times 0.5}{677}}}\\\\z=\dfrac{-0.001}{0.0192}\\\\z=-0.052$
