Answer:
$21
Step-by-step explanation:
$50×.60=$30
$50-$30=$20
$20×.05=$1
$20+$1=$21
Using Rise/Run, the answer would be y= -3/4x + 3.
Total numbers=10
mean(average)=14.8
standard deviation=3.4254
variance_standard deviation)=11.73333
population standard deviation=3.24962
variance(population standard deviation)=10.56
