While this question lacks the actual choices, determining the correct answer should be fairly easy. The "probability of success" that is being referred to here is the amount of numbers that will be listed. Since a probability of 80% is being looked for, we only have to choose the choice with 8 of the 10 numbers listed. This means that the answer is D. Hope this helps!

To avoid detection at customs, a traveler has placed 6 narcotic tablets in an Urn containing 9 vitamin pills that are similar in
Alexus [3.1K]

Answer:

\frac{4}{91}

Step-by-step explanation:  

We are told that to avoid detection at customs, a traveler has placed 6 narcotic tablets in an Urn containing 9 vitamin pills that are similar in appearance.

To find the probability that the traveler will be arrested for illegal possession of narcotics we will use theoretical probability formula.

\text{Probability}=\frac{\text{Number of favorable outcomes}}{\text{Number of possible outcomes}}

Favorable outcomes will be _{3}^{6}\textrm{C}.

\text{Favorable outcomes}=_{3}^{6}\textrm{C}=\frac{6!}{(6-3)!3!}

\text{Favorable outcomes}=\frac{6!}{3!3!}

\text{Favorable outcomes}=\frac{6\cdot 5\cdot 4\cdot3!}{3\cdot 2\cdot 1\cdot3!}

\text{Favorable outcomes}=\frac{6\cdot 5\cdot 4}{3\cdot 2}

\text{Favorable outcomes}=5\cdot 4=20

Now let us find number of possible outcomes.

\text{Number of possible outcomes}=_{3}^{15}\textrm{C}=\frac{15!}{(15-3)!3!}

\text{Number of possible outcomes}=\frac{15!}{12!3!}

\text{Number of possible outcomes}=\frac{15\cdot 14\cdot 13\cdot 12!}{12!\cdot 3\cdot 2\cdot 1}

\text{Number of possible outcomes}=\frac{15\cdot 14\cdot 13}{ 3\cdot 2\cdot 1}

\text{Number of possible outcomes}=5\cdot 7\cdot 13=455

Upon substituting our values in probability formula we will get,

\text{Probability that the traveler will be arrested for illegal possession of narcotics}=\frac{20}{455}

Upon dividing numerator and denominator by 5 we will get,

\text{Probability that the traveler will be arrested for illegal possession of narcotics}=\frac{4}{91}

Therefore, the probability that the traveler will be arrested for illegal possession of narcotics is \frac{4}{91}.

The cost yy (in dollars) to rent a moving van is proportional to the number xx of days that the van is rented. It costs $140 to
Arturiano [62]

Answer: y= 35x

Step-by-step explanation:

Given : The cost y (in dollars) to rent a moving van is proportional to the number x of days that the van is rented.

It costs $140 to rent a van for 4 days.

i.e. The cost of rent a moving van for 4 days = $140

Then, by unitary method ,

The cost of rent a moving van for 1 day = \dfrac{\$140}{4}=\$35

Now, the cost for renting a van for x days =

Cost of renting van for one day × (x)

= 35x

Then, the required equation that represents the cost to rent a moving van for x days :

y= 35x

What’s the answer??(SOMEONE PLEASE HELP ME)
Evgesh-ka [11]

To find f^{-1}, you can switch the "x" and "f(x) or y" in the equation.

f(x) = \sqrt[3]{x-2} +8

y = \sqrt[3]{x-2}+ 8

x = \sqrt[3]{y-2}+8

Now you need to isolate the "y"

x = \sqrt[3]{y-2}+8   Subtract 8 on both sides

x - 8 = \sqrt[3]{y-2}  Cube ( ³ ) each side to get rid of the ∛

(x-8)^{3} = (\sqrt[3]{y-2}) ^{3}

(x-8)^{3} = y -2   Add 2 on both sides

(x-8)^{3}+2 = y


f^{-1} = (x-8)^{3} + 2
