Answer: the percent of the students at this university are foreign = 30%
Step-by-step explanation:
Given: Probability that college students are foreign students who also smoke: P(S|F)=0.12
Probability that foreign college students smoke P(S∩F)=0.4
The probability that the students at this university are foreign :
[By conditional probability formula]

Hence, the percent of the students at this university are foreign = 30%
Answer:
-1/2
Step-by-step explanation:
The slope of a perpendicular line is opposite reciprocal. So the opposite of 2 is -2, and the reciprocal of 2 is 1/2.
Replace X and Y in the given equations and see if they are true:
2(5) + 2(1) = 10+2 = 12... does not equal 11 So this in not right.
2(5) +3(1) = 10 + 3 = 13 this is correct.
The answer would be: 2x+3y=13
