Alab is trying to determine if a new medication is effective at reducing acne breakouts. the results are displayed in the venn diagram below in the attachment:
what is the probability that the person's skin cleared up given that they used the medication?
a. 10%
b. 20%
c. 30%
d. 60%

D. 60%

Step-by-step explanation:

Let A = Event that person's skin cleared up

B= Event that person used the medication.

T be the total number of persons in this experiment.

From the Venn diagram , we have

n(A ∩ B) = 30

n (only A) = 10 and n(only B)=20

so , n(A)=n (only A) +n(A ∩ B) =10+30=40

n(B)=n(only B)+n(A ∩ B) =20+30=50

Now, the probability that the person's skin cleared up given that they used the medication :-

In percent , P(A|B)=60%

Hence, the probability that the person's skin cleared up given that they used the medication = 60%

i do not know the answer i am sorry

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
