Solve the simultaneous equation <br> 2x-5y=9<br> 3x+4y=2
Dmitriy789 [7]

Answer/Step-by-step explanation:

2x-5y=9

Add 5y  to both sides of the equation.

2x=9+5y

Divide each term by 2 and simplify.

Divide each term in 2x=9+5y by 2

\frac{2x}{2} =\frac{9}{2} +\frac{5y}{2}

Cancel the common factor of 2.

Divide x by 1.

x=\frac{9}{2} +\frac{5y}{2}

y=\frac{-9}{5} +\frac{2x}{5}

----------------------------------------------------------------------------------------------------------------

3x+4y=2

Add 4y to both sides of the equation

3x=2+4y

Divide each term by 3 and simplify.

Divide each term in 3x=2+4y by 3.

\frac{3x}{3} =\frac{2}{3} +\frac{4y}{3}

Cancel the common factor of 3.

Divide x by 1.

x=\frac{2}{3} +\frac{4y}{3}

y=\frac{-1}{2} +\frac{3x}{4}

Suppose P(E) = 81%; P(E and F) = 9%; and P(E or F) = 65%,
PIT_PIT [208]

Using Venn probabilities, it is found that P(F) = -0.07, which is not a probability, as it is a negative value.

------------------

  • We have two events, E and F.
  • Their probabilities are: P(E) = 0.81, P(E \cap F) = 0.09, P(E \cup F) = 0.65
  • The probabilities are related by the following equation:

P(E \cap F) = P(E) + P(F) - P(E \cup F)

  • Replacing into the equation, we can find P(F).

0.09 = 0.81 + P(F) - 0.65

0.16 + P(F) = 0.09

P(F) = -0.07

P(F) = -0.07, which is not a probability, as it is a negative value.

Interval notation, I need help with this and I can't figure out how to do it!!
aliya0001 [1]

To find A∩B, you need to find the values that both data sets include, or where they overlap. Both data sets include the number range of 0 to 3. Because both data sets include 0, but set A does not include 3, the answer is [0, 3).
