After you solve for both sides x=90
the idea behind the completion of the square is simply using a perfect square trinomial, hmmm usually we do that by using our very good friend Mr Zero, 0.
if we look at the 2nd step, we have a group as x² - x, hmmm so we need a third element, which will be squared.
keeping in mind that the middle term of the perfect square trinomial is simply the product of the roots of "a" and "b", so in this case the middle term is "-x", and the 1st term is x², so we can say that
so that means that our missing third term for a perfect square trinomial is simply 1/2, now we'll go to our good friend Mr Zero, if we add (1/2)², we have to also subtract (1/2)², because all we're really doing is borrowing from Zero, so we'll be including then +(1/2)² and -(1/2)², keeping in mind that 1/4 - 1/4 = 0, so let's do that.
If the probability that she will be picked is 2/38 = 1/19
then the probability that she won't be picked is 36/38 = 18/19
I think the correct given number is 212 base 3 and we are
asked to convert this number into base 2.
We should recall that a number let us say X with a base of
Y can also be written as:
X base Y = log X / log Y
Therefore in this case, the new number base should be
equal to the initial number base. That is:
log 212 / log 3 = log X / log 2
So let us find for X:
log X = (log 212 / log 3) * log 2
X = 10 ^ [(log 212 / log 3) * log 2]
X = 10 ^ (1.467754511
X = 29.36
Therefore the new form would be:
