To simplify most teachers prefer to round to tenth or hundreth
best answers: 0.9, 0.87
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.
You take 16 and -5 and subtract them to get the answer which is 11

Answer:
33400
Step-by-step explanation:
If it is scaled by a factor of 10, every side length is multiplied by 10. So you can do the work of:
80*30*2 + 80*130*2 + 30*130*2= 33400
