Answer:

2/3

Step-by-step explanation:

A = Student studying Math

B = Student studying Science

P(B|A) = P(A and B) ÷ P(A).

P(B|A) means the probability of event B given event A.

Given :

P(A and B) = 0.40.

Also P(A) = 0.60.

P(B|A) = 0.40 ÷ 0.60 = 2 ÷ 3.

So, the answer is 2/3.

A certain bacterial culture is multiplying in a culture dish, doubling in size every 6 minutes. It takes exactly an hour to fill

Furkat [3]

Doubling in size,

if the whole dish is filled in an hour (all of it)
how long does it take to fill 1/2 dish?

notice that
1/2 doubled=1/2 times 2=2/2=1 whole dish
therefor it only doubled one more time from the 1/2 point

1hour=all
1hour-6mins=1/2 dish

1hour-6mins=60-6=54 minutes

answer is 54 minutes
