Contestants on a game show spin a wheel with 242424 equally-sized segments. Most of those segments show different prize amounts,
ycow [4]

Using the principle of probability, the probability that the outcome of both spins does not land on "<em>bankrupt</em><em>"</em><em> </em>is 1/144

<u>Given</u><u> </u><u>the</u><u> </u><u>Parameters</u><u> </u><u>:</u>

  • Total Number of possible outcomes = 24
  • Number of outcomes labeled bankrupt = 2
  • Labels which aren't labeled bankrupt = 24 - 2 = 22

<u>Recall</u><u> </u><u>:</u>

  • P(A) = <em>required</em><em> </em><em>outcome</em><em> </em><em>/</em><em> </em><em>Total</em><em> </em><em>possible outcomes</em><em> </em>

<u>First</u><u> </u><u>spin</u><u> </u><u>:</u>

  • P(not bankrupt) = 2 / 24 = 1/12

<u>Second</u><u> </u><u>spin</u><u> </u><u>:</u>

  • P(not bankrupt) = 2/24 = 1/12

P(<em>neither</em><em> </em><em>lands</em><em> </em><em>on</em><em> </em><em>bankrupt</em><em>)</em><em> </em><em>=</em><em> </em>1/12 × 1/12 = 1/144

Therefore, the probability that neither lands on bankrupt is 1/144

A 41 gram sample of a substance that's used to detect explosives has a k-value of 0.1392. Find the substance's half life, in day
-BARSIC- [3]

Answer:

The substance half-life is of 4.98 days.

Step-by-step explanation:

Equation for an amount of a decaying substance:

The equation for the amount of a substance that decay exponentially has the following format:

A(t) = A(0)e^{-kt}

In which k is the decay rate, as a decimal.

k-value of 0.1392.

This means that:

A(t) = A(0)e^{-0.1392t}

Find the substance's half life, in days.

This is t for which A(t) = 0.5A(0). So

A(t) = A(0)e^{-0.1392t}

0.5A(0) = A(0)e^{-0.1392t}

e^{-0.1392t} = 0.5

\ln{e^{-0.1392t}} = \ln{0.5}

-0.1392t = \ln{0.5}

t = -\frac{\ln{0.5}}{0.1392}

t = 4.98

The substance half-life is of 4.98 days.

How can you find f(2) if f(x)=3x^2-2
Ganezh [65]

Answer:

f(2) = 10

Step-by-step explanation:

Simply just plug in 2 into the equation

f(2) = 3(2)² - 2

f(2) = 3(4) - 2

f(2) = 12 - 2

f(2) = 10

And we have our final answer!
