Answer:

Explicit formula is an = 64(-3/4)^(n-1).

Step-by-step explanation:

Looks like a geometric sequence with a negative common ratio.

-48/64 = - 3/4

36 / -48 = -3/4

Now -27/36 = -3/4 so I think there's a typo in the question. Its -27 not -17.

The required formula is 64(-3/4)^(n-1) .

Answer:

900 meters

Step-by-step explanation:

There are about 3 feet in a meter, so to find the answer you have to add up all the meters he swam and then multiply it by that.

So the equations will be: 100+200=300, 300x3=900.

Probability that the first captain's first pick is a girl = 11/21
Probability that the first captain's second pick is a girl = 12/25

the probability that the first captain will pick two girls before picking any boys = 11/21 x 12/25 = 132/525 = 44/175
