Mathematics
1 answer:
Gwar [14]3 years ago
3 0

Answer:

\boxed{\boxed{\tt B)-2}}

Step-by-step explanation:

\tt 2+\left(-\cfrac{2}{3}\right)2\div \cfrac{1}{3}

Express -2/3 × 2 as a single fraction:

\tt 2+\cfrac{\cfrac{-2\times 2}{3} }{\cfrac{1}{3} }

Multiply -2 × 2 = -4

\tt 2+\cfrac{\cfrac{-4}{3} }{\cfrac{1}{3} }

Now, rewrite fraction \tt \frac{-4}{3} as \tt -\frac{4}{3} by extracting the (-) sign:

\tt 2+\cfrac{-\cfrac{4}{3} }{\cfrac{1}{3} }

Divide - 4/3 by 1/3 by multiplying - 4/3 by the reciprocal → 1/3

\tt 2-\cfrac{4}{3} \times 3

Cancel out 3 and 3:

\tt 2-4

Subtract numbers:

\tt -2

The lifespan, in years, of a certain computer is exponentially distributed. The probability that its lifespan exceeds four years
kompoz [17]

Answer:

The correct answer is "0.300993e^{-0.300993x}".

Step-by-step explanation:

According to the question,

⇒ P(x>4)=0.3

We know that,

⇒ P(X > x) = e^{(-\lambda\times x)}

⇒     e^{(-\lambda\times 4)} = 0.3

∵ \lambda = 0.300993

Now,

⇒ f(x) = \lambda e^{-\lambda x}

By putting the value, we get

           =0.300993e^{-0.300993x}

After robbing a bank in dodge city, a robber gallops off at 14 mi/h. 20 minutes later, the marshall leaves to pursue the robber
Morgarella [4.7K]

For this case we have to write the equation of the position of each one.

We have then:

For the robber:

r = 14t

For the marshall :

r = 16 (t- (\frac{20}{60}))

r = 16 (t-\frac{1}{3})

By the time the marshall reaches the robber we have:

14t = 16 (t-\frac{1}{3})

From here, we clear the time.

We have then:

16t - 14t = \frac{16}{3}

2t = \frac{16}{3}

t =\frac{8}{3}

t = 2.7 h

Answer:

it takes the marshall to catch up to the robber about 2.7 hours.
