Y=10x+20
y=10×5y+20
y=50y+20
-20=50y-y
-20=49y
y=-20/49
Because it has three legs
$3.00-$2.40 = $0.60
$0.60/$3.00 = $0.2
$0.2x100 = 20% decrease
Answer:
There is 0.1538 or 15.38% probability that the next person Rona sees will be wearing boots.
Step-by-step explanation:
Total number of People = 13
People wearing boot = 2
Experimental Probability = Number of times event occurs / Total Number of Trials
Experimental Probability = 2 / 13
Experimental Probability = 0.1538
Or
Experimental Probability = 15.38%
So, there is 0.1538 or 15.38% probability that the next person Rona sees will be wearing boots.
