Answer:
0.405 or 40.5%
Step-by-step explanation:
Let event A=having a periodontal disease
event B=having a heart attack
we are given
P(A)=P(having a periodontal disease)=0.30
P(B)=P(having a heart attack)=0.15
P(A/B)=P(have a periodontal disease/have a heart attack)=0.81
P(B/A)=P(have a heart attack/have a periodontal disease)=?
P(A/B)=P(A∩B)/P(B)
P(A∩B)=P(B)*P(A/B)=0.15*0.81=0.1215
P(B/A)=P(A∩B)/P(A)=0.1215/0.3=0.405
There is 40.5% probability that if someone has periodontal disease will have a heart attack.
-2x + 60
15,30
15 fruit, 30 vegetable
Divide the amount left by the percentage left:
they sold 35%, so there is 65% remaining.
280 / 0.65 = 430.769
Round to 431
Now check:
431 x 0.35 = 150.85
Round to 151
431 - 151 = 280 left.
They originally had 431 peaches.

I hope this helps!
It's 4.25
5/2= 2.5
7/4=1.75
2.5+1.75=4.25
