Answer:
$226
Step-by-step explanation:
1. define the variable x
x = # of days to rent the carpet cleaner
2. substitute x for 7 days
c(7) = 30(7) + 16
3. solve
c(7) = 210 + 16
c(7) = 226
For 7 days, Rhonda will have to rent the carpet cleaner for $226.
<span>The minus sign of the z-score shows that the score is below the mean.
6 points below the mean means the difference of the score and mean is -6
z = (X-Mean)/SD
-0.50 = -6 / SD
SD = -6/-0.50 = 12
The population standard deviation = 12</span>
