You must find the same denominator by finding the closest common factor of both.
In this case it would be 15 because both 5 and 3 go into 15.
You then have to multiply the numerator by the number you multiplied to get the denominator.
So you multiply

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.

Rewrite ^3 sqrt 27x-81-5 to make it easy to graph a translation. Describe the graph.
iragen [17]
First we have to rewrite this function.Instead of :^3 sqrt (...) we can write : (...)^(1/3).
f ( x ) = ( 27 x - 81 ) ^(1/3) - 5 = ( 27 * ( x - 3 ) ) ^(1/3) - 5 = = 3 * ( x - 3 )^(1/3) - 5 And this makes it easy to graph a translation.The parent function is y = x^(1/3). The zero of this function is ( 0, 0 ).
Then it will be stretched vertically by a factor of 2 and translated: 3 units right and 5 units down.
