Arianna sold for $ 299.6
<em><u>Solution:</u></em>
Given that, Part of Arianna’s earnings are based on a 5% commission rate
At the end of the day arianna earned 14.98 in commission
Therefore,
Commission earned = $ 14.98
Commission rate = 5 %
Let "x" be the amount that Arianna sell that day
Therefore, according to question,
5 % of amount earned = 14.98
5 % of "x" = 14.98
<em><u>Solve the above equation for "x"</u></em>
Thus arianna sold for $ 299.6
Answer:
0.8675
Step-by-step explanation:
Given that people ages 16-30 make up 15% of drivers on the road, 80% of drivers are aged 31-64, and 5% of drivers are aged 65+.
Furthermore, suppose drivers in each age range cause car accidents at the rates of 6%, 4%, and 9%, respectively.
age 16-30 31-64 >65
Prob 0.15 0.8 0.05 1
Prob for accidents 0.06 0.09 0.04
Product 0.009 0.072 0.002 0.083
Prob for 31-64 causing it/accident =
Using Bayes theorem we got answer as 0.8675
