Records show that 12% of all college students are foreign students who also smoke. It is also known that 40% of all foreign coll

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%

If 10^2y = 25, then 10^-y equals: (a) -1/5 (b) 1/625 (c) 1/50 (d) 1/25 (e) 1/5

Gemiola [76]

<h3>given:</h3>

$10 ^{2y} = 25$

${10}^{y} = .......$

<h3>solution:</h3>

$10 ^{2y} = 25$

$(10y {)}^{2} = {5}^{2}$

$10y = 5$

$\frac{1}{ {10}^{y} } = \frac{1}{5}$

${10}^{ - y} = \frac{1}{5}$

therefore, the correct answer is option E.

Use the following isosceles triangle to find valur of x and the length of ac.

marissa [1.9K]

Given that the triangle is isosceles, we can say that AB = AC. Using the given expressions we can form the following equation.

$\begin{gathered} AB=AC \\ 5x+8=7x-6 \end{gathered}$

Let's solve for x.

$\begin{gathered} 8+6=7x-5x \\ 14=2x \\ x=\frac{14}{2} \\ x=7 \end{gathered}$

Once we have the value of the variable, we can find the length of AC.

$\begin{gathered} AC=7x-6 \\ AC=7(7)-6 \\ AC=49-6 \\ AC=43 \end{gathered}$ <h2>Therefore, the length of AC is 43.</h2>
