Twenty identical looking packets of white power are such that 15 contain cocaine and 5 do not. Four packets were randomly select
xxMikexx [17]

Answer:

The probability of selecting randomly 6 packets such that the first 4 contain cocaine and 2 not is 0.3522.

Step-by-step explanation:

Probabilities of selecting 4 packets with the ilegal substance:

(\frac{15}{4})\\= \frac{15!}{4!(15-4)!}

Combinassions possible= 1365

Probabilities of selecting 2 packets with white powder:

(\frac{5}{2})= \frac{5!}{2!(5-2)!}

Combinations possible= 10

Probabilities of selecting 6 packets from the totality of them:

(\frac{20}{6}) = \frac{20!}{6!(20-6)!}

Combinations possible= 38760

The probability of picking 4 with the substance and 2 with only white powder is:

\frac{(15ncr4)(5ncr2)}{(20ncr6)} = 0.3522

I hope this answer helps you.

Solve 3(x + 2) &gt;x<br>Please ​
Anon25 [30]

Answer:

x > −3

Step-by-step explanation:

Let's solve your inequality step-by-step.

3(x + 2) > x

Step 1: Simplify both sides of the inequality.

3x + 6 > x

Step 2: Subtract x from both sides.

3x + 6 − x > x − x

2x + 6 > 0

Step 3: Subtract 6 from both sides.

2x + 6 − 6 > 0 − 6

2x > −6

Step 4: Divide both sides by 2.

2x / 2 > −6 / 2

x > −3

Answer:

x > −3

Hope this helps :)

How many circles with a 3ft radius could fill a 100 square foot (10ft x 10ft) space without overlap?
Alborosie

Answer:

1

Step-by-step explanation:

Considering that the circle has radius of 3ft to mean its diameter is twice the radius hence 6 ft

Given that the length of the square is 10 ft

10÷6=1 ⅔ hence only 1 circle

10-6=4 ft

The space of 4ft can't allow another circle to fit without an overlap. Therefore, only one circle can fit
