A recursive rule for a geometric sequence is
LuckyWell [14K]

Answer:

C. a_n=(9)(\frac{2}{3})^{n-1}

Step-by-step explanation:

Iterative geometric sequence:

a_n=a_1x^{n-1}

Recursive geometric sequence:

a_n=xa_{n-1}

The equations are very similar and you only really need to rearrange it. The factor (2/3) and the first term (9) are given, so you can write the iterative equation:

a_n=(9)(\frac{2}{3})^{n-1}

And so the answer is C.

A box contains 12 balls of which 5 are red, and 7 are blue. If 4 balls are drawn from the box, in how many ways can this be done
mash [69]

Answer:

175 ways

Step-by-step explanation:

5 balls are red, and 7 balls  are blue making a total of 12 balls.

4 balls are drawn from the box,

1 ball is red and 3  balls are blue out of the 4 drawn from the box.

We have to choose 1 ball from 5 red balls and 3 blue balls from 7 blue balls.

Since the order is not essential we use combinations to find out

5C1 * 7C3= 5*35 = 175 ways
