Write the equation of the line that passes through (2, 3) and is parallel to the line 12x – 5y = 2.

Alexeev081 [22]

   12x - 5y = 2
12x - 12x - 5y = -12x + 2
   -5y = -12x + 2
      -5 -5
      y = 2.4x - 0.4
   y - 3 = 2.4(x - 3)
   y - 3 = 2.4(x) - 2.4(3)
   y - 3 = 2.4x - 7.2
         + 3    + 3
      y = 2.4x - 4.2

What is 2/10 divided by 2/4

shtirl [24]

Given:

$\dfrac{2}{10}$ divded by $\dfrac{2}{4}$ .

To find:

The solution for the given division problem.

Solution:

We have, $\dfrac{2}{10}$ divded by $\dfrac{2}{4}$ . It can be written as

$\dfrac{2}{10}\div \dfrac{2}{4}=\dfrac{2}{10}\times \dfrac{4}{2}$

$\dfrac{2}{10}\div \dfrac{2}{4}=\dfrac{2\times 4}{10\times 2}$

$\dfrac{2}{10}\div \dfrac{2}{4}=\dfrac{8}{20}$

$\dfrac{2}{10}\div \dfrac{2}{4}=\dfrac{2}{5}$

Therefore, the solution for the given division problem is $\dfrac{2}{5}$ .

Gnesinka [82]

Answer:

1/41416353 probability of all five numbers and the mega number matching the winning numbers

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question, the order of the numbers is not important. So we use the combinations formula to solve this question.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

Probability of the five numbers matching:

Desired outcomes: 1 -> the matching numbers

Total outcomes: 5 from a set of 47. So

$T = C_{47,5} = \frac{47!}{5!(47-5)!} = 1533939$

Probability:

$p_{S} = \frac{1}{1533939}$

Probability of the mega number matching:

1 from a set of 27. So

$p_M = \frac{1}{27}$

Probability of both matching:

Independent events, so we multiply the probabilities:

$p = p_S*p_M = \frac{1}{1533939}*\frac{1}{27} = \frac{1}{41416353}$

1/41416353 probability of all five numbers and the mega number matching the winning numbers
