There are 3 red chips and 2 blue chips. If they form a certain color pattern when arranged in a row, for example RBRRB, how many
svp [43]

Answer:

Option A - 10

Step-by-step explanation:

Given : There are 3 red chips and 2 blue chips. If they form a certain color pattern when arranged in a row, for example RBRRB.

To find : How many color patterns are possible?

Solution :

Total number of chips = 5

So, 5 chips can be arranged in 5! ways.

There are 3 red chips and 2 blue chips.

So, choosing 3 red chips in 3! ways

and choosing 2 blue chips in 2! ways.

As changing the places of similar chip will not create new pattern.

The total pattern is given by,

T=\frac{5!}{3!\times 2!}

T=\frac{5\times 4\times 3!}{3!\times 2}

T=10

Therefore, color patterns are possible are 10.

Option A is correct.

Find the sum of the geometric series 9000-900 +...+ 0.009
bagirrra123 [75]

Based on the calculations, the sum of this geometric series is equal to 9,990.

<h3>The standard form of a geometric series.</h3>

Mathematically, the standard form of a geometric series can be represented by the following expression:

\sum^{n-1}_{k=0}a_1(r)^k

Where:

  • a₁ is the first term of a geometric series.
  • r is the common ratio.

<h3>How to calculate the sum of a geometric series?</h3>

Also, the sum of a geometric series is given by this mathematical expression:

S=\frac{a_1(1-r^n)}{1-r}

<u>Given the following data:</u>

  • First term, a = 9000.
  • Common ratio, r = 900/9000 = 0.1

Substituting the given parameters into the formula, we have;

S=\frac{9000(1-0.1^3)}{1-0.1}\\\\S=\frac{9000(1-0.001)}{1-0.1}

S = 9000(0.999)/0.9

S = 8,991/0.9

S = 9,990.
