Why in these types of questions(the image) I need to multiply the dominator by itself and by the nominator. and why I can't just
Lana71 [14]

Answer:

\frac{\sqrt{5x^{2} } }{\sqrt{3x^{3} } } =\sqrt{\frac{5}{3x} }

Step-by-step explanation:

Simply because

A=\frac{5}{3} = \frac{5}{3}*\frac{3}{3}  = \frac{15}{9} =\frac{5}{3}

So its value remains Constant , It's simply as if you're multiplying by 1 which doesn't change anything at all

but when doing this

A=\frac{5}{3} = \frac{5}{3}*\frac{5}{3}  = \frac{25}{9} \neq \frac{5}{3}\\

You changed its value

A now became A^{2}

Hope you understand it

Assuming a data set with 660 training outcomes of which 368 are positive, what is the Entropy
aleksandrvk [35]

Answer:

0.9905

Step-by-step explanation:

Let p_{1}, p_{2},..., p_{n} be the probabilities of all possible outcomes of an event.

Then Entropy(E) can be calculated using the equation

  • E=-p_{1}*log_{2}(p_{1}) -p_{2}*log_{2}(p_{2}) - ..- p_{n}*log_{2}(p_{n})

In the data set there are two outcomes: <em>positive</em> and <em>negative</em>.

  • p_{positive}=\frac{368}{660} ≈ 0.5576
  • p_{negative}=\frac{292}{660} ≈ 0.4424

Thus, E=p_{positive}*log_{2}(p_{positive}) +p_{negative}*log_{2}(p_{negative}) = -0.5576*log_{2}(0.5576) -0.4424*log_{2}(0.4424)

=-(log_{2}(0.5576^0.5576) +log_{2}(0.4424^0.4424))

=-(log_{2}((0.5576^0.5576)*(0.4424^0.4424)))

=-(log_{2}(0.5033))

=0.9905

Find the supplement of a 118° angle.
wel
Supplementary angles add to equal 180 degrees. Adjacent supplementary angles are supplements of each other. To find the supplement of an angle that measures 118 degrees, subtract 118 from 180.

180 - 118 = 62

Answer:
The supplement of a 118° angle measures 62°.
