Answer:

Fr^2/Gm_2=m_1

Step-by-step explanation:

What you do first is you have to cross-multiply so f*r^2 and 1*gm_1m_2 to get

Fr^2=Gm_1m_2. Next you will divide Gm_2 from both sides to get

Fr^2/Gm_2=m_1 as your answer.

Based on the diagram shown, find θ to the nearest degree.
sattari [20]

Answer:

  θ = 38°

Step-by-step explanation:

The lower right triangle is congruent to the upper left triangle, so we have θ and 20° being the two acute angles in the triangle. The law of sines tells you ...

  sin(θ)/9 = sin(20°)/5

  sin(θ) = (9/5)sin(20°)

  θ = arcsin(9/5·sin(20°)) ≈ 38°

___

Another solution to the triangle is θ = 180° -38° = 142°. The diagram clearly shows θ as an acute angle, so we take this second solution to be extraneous.

"the life length x (in years) of a dvd player" is exponentially distributed with mean 5 years. what is the probability that a mo
loris [4]
The exponential distribution is:
\lambda e^{- \lambda x}
where \lambda = \frac{1}{mean}=\frac{1}{5}

The probability we want is how likely will a dvd player last more than 8 years, given it has already lasted 5 years
To find this, you use conditional probability.
P(A|B) = \frac{P(A and B)}{P(B)}
where A is P(x>8) and B is P(x>5)
To find these probabilities, integrate over the distribution:
P(x \ \textgreater \ N) = \int_N^{\infty} \frac{1}{5} e^{-x/5} dx = e^{-N/5}

Sub into conditional probability formula:

P(x \ \textgreater \ 8 | x\ \textgreater \ 5) = \frac{P(x\ \textgreater \ 8)}{P(x\ \textgreater \ 5)} = \frac{e^{-8/5}}{e^{-5/5}} = e^{-3/5} = 0.549

Final Answer: Given a dvd player is more than 5 years old, the probability that it will last another 3 more years is about 54.9%

Using conversions of mixed numbers, the numbers that are equivalent to 2 and 7/9 are given by:

25/9 and 2.777.

<h3>What are the conversions of the mixed number 2 and 7/9?</h3>

To convert to decimal, we just add the integer part with the fractional part converted to decimal(dividing the numerator by the denominator), hence:

2 and 7/9 = 2 + 7/9 = 2.7777.

To convert to fraction, the procedure is similar, we just apply the least common multiple to add the fraction, as follows:

2 + \frac{7}{9} = \frac{2 \times 9 + 7}{9} = \frac{25}{9}

Hence the numbers that are equivalent to 2 and 7/9 are given by:

25/9 and 2.777.
