solution:
P(passed)=P(Dr. J and passed)+P(Dr. S and passed) =0.4*0.8+(1-0.4)*0.6=0.68
hence probability that she was enrolled in Dr. J's section given passed
=P(Dr. J and passed)/P(passed)=0.4x0.8/0.68=0.4706

Answer:
4x
Step-by-step explanation:
The LCD of 1/17 and 3/14 is 14.
1/7 = 2/14
3/14 = 3/14
2 + 3 = 5
The denominators are the same, so it will remain the same.
= 5/14 <===
5/14 is your answer.
I hope this helps! :)
(a) * (a+1) = 420
a^2 + a = 420
a^2 + a - 420 = 0
(a+21)(a-20) = 0
a = -21 OR 20
The two integers can be -21 and -20, OR 20 and 21.
