Firstly, subtract 3 on both sides of the equation:
Next, divide by a:
Lastly, square root both sides, and your answer will be
<u>Answer:</u>
P (S∩LC) = 0.03
<u>Step-by-step explanation:</u>
We are given that the probability that someone is a smoker is P(S)=0.19 and the probability that someone has lung cancer, given that they are a smoker is P(LC|S)=0.158.
Given the above information, we are to find the probability hat a random person is a smoker and has lung cancer P(S∩LC).
P (LC|S) = P (S∩LC) / P (S)
Substituting the given values to get:
0.158 = P(S∩LC) / 0.19
P (S∩LC) = 0.158 × 0.19 = 0.03
Answer:
x=1 y=2
Step-by-step explanation:
x=1 y=2
8x +4 y=16
8(1) + 4(2)=16
8+8=16
this is correct so now lets check the other one
7y=15-x
7(2)=15-(1)
14=14
this is also correct
Answer:
