A lab is trying to determine if a new medication is effective at reducing acne breakouts. The results are displayed in the Venn

Diagram below: A Venn Diagram titled Acne medicine probabilities is shown with two circles labeled used the medicine and skin cleared. Inside the used the medicine area is 20. Inside the skin cleared area is 10. In the intersection of the two circles is 30. The area outside the two circles is labeled 40. What is the probability that the person's skin cleared up given that they used the medication?

The probability that the person's skin cleared up given that they used the medication would be 60 percent. From the problem statement, the area given for each section represents the number of data that corresponds to used the medicine, skin cleared and for both. To determine the probability of the person's skin that cleared up using the medication, we simply divide the total number of persons that used the medicine, that is 30+20 = 50, to the number that represent for both which is 30. Therefore,

probability <span>that the person's skin cleared up using the medication = 30 / 50 x 100 = 60 percent</span>

Answer: 3/5 is the probability that person's skin cleared up given that they used the medication.

Step-by-step explanation:

let S represents skin cleared and M represents medicine used.

According to the given Venn diagram,

P(S) = 40

P(M)= 50

P(M\cap S) = 30

Thus by the definition of conditional probability,

If it is given that the skin is cleared then the probability that persons used the medicine,

P(M/S)=\frac{P(M\cap S)}{P(S)}=30/50= 3/5.

P(M/S)=3/5.

Zhang Lei spent $20.00 during his last outing at the bowling alley. This included a one time shoe rental fee of $3.50. He spent
Afina-wow [57]

Answer: The cost per game is $5.5

Step-by-step explanation:

Zhang Lei spent $20.00 during his last outing at the bowling alley. There is a one time shoe rental fee of $3.50. He spent the rest of the money on bowling a number of games.

This means that amount paid for x number of games = 20 - 3.5 = $16.5

If it took Zhang Lei 45 minutes to bowl each game and he spent 2 hours and 15 minutes bowling, total time spent in minutes is 120+ 15 = 135 minutes. Therefore, the number of games is played is 135/45 = 3

If the total number of games played cost 16.5, therefore, the cost per game will be 16.5/3 = $5.5

-4y = 16 <br> identify the slope and y intercept
Shalnov [3]

Answer:

zero slope

y-intercept at y = -4

Step-by-step explanation:

-4y = 16  (divide both sides by -4)

y = 16 / (-4)

y = -4

y = -4 represents a horizontal line that is parallel to the x-axis that crosses the y-axis at y = -4

hence the slope of a horizontal line is zero, and the y-intercept is -4
