Answer:

C. x+log(z)

Step-by-step explanation:

Taking the log of the equation gives ...

log(z) = (x -y)log(1/10) = (x -y)log(10^-1)

log(z) = (x -y)(-1) = y -x

Adding x gives ...

x + log(z) = y . . . . . matches choice C

A recent poll of 80 randomly selected Californians showed that 38% ( = 0.38) believe they are doing all that they can to conserv

Elanso [62]

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%
