Sati [7]

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 :

P(F)=\dfrac{P(S\cap F)}{P(S|F)}  [By conditional probability formula]

=\dfrac{0.12}{0.4}\\\\=0.3

Hence, the percent of the students at this university are foreign = 30%

  y = -1/2x +12

Help Please?<br> Solve for x. <br><br> x − 2.7 ≥ 10.3<br><br> Solve for x. <br><br> −0.84x ≤ 168
stiks02 [169]
For the first one, we add 2.7 to both sides to get x≥13. Next, we divide both sides by -0.84 to get x≥ 168/-0.84. SInce we multiplied or divided by a negative number, we switch the sign around and end up with x≥200
