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%

Jobisdone [24]

Answer:

92 miles

Write an inequality for the total cost of the rental.

Cost of the rental = 19.50+0.25x<=44

where x is the number of miles driven.

Subtract 19.50 from both sides.

0.25x<=44-19.50

0.25x<=24.5

x<=24.5/0.25

x<=98
