According to the general equation for conditional probability if p(a^b) =3/10

The correct answer for the question that is being presented above is this one: "A. (3/8)." According to the general equation for conditional probability if P(AupsidedownuB) = (3/10) and P(B)= (2/5), then P(A|B) is 3/8.
Here are the following choices:
A. (3/8)
B. (1/2)
C. (3/4)
D. (1/16)

If the object travels 3.2 meters in 2 seconds, it would take 4.34 seconds to travel 15 meters.

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

The distance traveled by an object falling freely is proportional to the square of the time passed after the release of the object.

Mathematically speaking:

d = k t²

Where:

d = distance

t = time

k = constant

We have to find the value of "k", using the values of "d" and "t" given .

3.2 = k 2²

3.2 = k 4

3.2 / 4 =k

0.8 = k

Finally, to find the time that takes travel 15 meters:

d = 0.8 t²

15 = 0.8 t²

15/0.8 = t²

√18.75 =t

t= 4.34 seconds

If the object travels 3.2 meters in 2 seconds, it would take 4.34 seconds to travel 15 meters.
