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.
Combine like terms
7p+8p-12=59
15p-12=59
add 12 to both sides
15p+12-12=59+12
15p+0=71
15p=71
divide both sides by 15
p=4 and 11/15

Answer:
The unit rate is $0.37 per popsicle.
Step-by-step explanation:
Unit rate represents the rate per one unit. In this case, the unit rate would represent the cost per popsicle. Since one box contains a total of 12 popsicles, we need to take the total cost of the box ($4.44) and divide by the number of popsicles that come in the box, or 4.44/12. When we divide, we get 0.37, or $0.37 per popsicle.
we have that
