Kobotan [32]

Answer:

The margin of error for the survey is 0.016

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 1024

Sample proportion:

$\hat{p} = 89\% = 0.89$

We have to find the margin of error associated with a 90% Confidence interval.

Formula for margin of error:

$z_{stat}\times \sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}$

$z_{critical}\text{ at}~\alpha_{0.10} = 1.64$

Putting the values, we get:

$M.E = 1.64\times (\sqrt{\dfrac{0.89(1-0.89)}{1024}})\\\\M.E=0.016$

Thus, the margin of error for the survey is 0.016

3^b=17 exponentials into log form

IRINA_888 [86]

Solve for the real domain

$3^b = 17$

if f(x) = g(x) , then ln (f(x)) = ln (g(x))

$ln ( 3^b) = ln (17)$

$log _{a} (x^b) = b*log _{a} (x)$

$ln(3^b) = bln(3)$

$bln(3) = ln (17)$

Solve $bln(3) = ln (17)$

$b = \frac{ln(17)}{ln(3)}$

hope this helps !.
