A bag contains 6 gray tiles and 3 blue tiles. Jenny reached into the bag and picked a tile
Arisa [49]

Answer:

The probability that Jenny picked a gray tile with her second pick given that she picked a blue tile with her first pick = 0.25

Step-by-step explanation:

i.) there are 6 gray tiles and 3 blue tiles

ii) the probability that Jenny picked a blue tile first is given by

\frac{number\hspace{0.1cm} of \hspace{0.1cm} blue\hspace{0.1cm}  tiles }{total \hspace{0.1cm}number\hspace{0.1cm} of \hspace{0.1cm}tiles\hspace{0.1cm}  }  = \frac{3}{9}  = \frac{1}{3}

iii) the probability that Jenny picked a gray tile with her second pick without replacing the first tile\frac{number\hspace{0.1cm} of \hspace{0.1cm} blue\hspace{0.1cm}  tiles }{total \hspace{0.1cm}number\hspace{0.1cm} of \hspace{0.1cm}tiles\hspace{0.1cm}  } \times    \frac{number\hspace{0.1cm} of \hspace{0.1cm} gray\hspace{0.1cm}  tiles }{total \hspace{0.1cm}number\hspace{0.1cm } of \hspace{0.1cm}tiles\hspace{0.1cm} - 1 }  = \frac{3}{9} \times \frac{6}{8}  = \frac{1}{3} \times  \frac{3}{4} = \frac{1}{4} = 0.25

The probability that Jenny picked a gray tile with her second pick given that she picked a blue tile with her first pick = 0.25

Write this equation in vertex form.<br> y = x^2 -12x +20
kotegsom [21]

Answer:

y = (x-6) ^ 2 -16

Step-by-step explanation:

The vertex form for a quadratic equation has the following form:

y = (x-h) ^ 2 + k

Where the vertice of the equation is the point (h, k)

To transform the equation y = x ^ 2 -12x +20 in its vertex forms we must find its vertex.

Be a quadratic equation of the form:

ax ^ 2 + bx + c

Where a, b and c are real numbers, then the vertex of the equation will be:

x = - \frac{b}{2a}

For the given equation:

b = -12\\a = 1

Therefore the vertice is:

x = - \frac{-12}{2(1)}\\\\x = 6

Now we substitute x = 6 into the equation and find the value of k.

y = (6) ^ 2 -12 (6) +20\\\\y = -16 = k

Therefore the vertice is: (6, -16)

And the equation is:

y = (x-6) ^ 2 -16

Which number produces an irrational number when multiplied by 1/3
MArishka [77]

We can simply observe that.

  1. 0.777... is rational, because it is a number with infinite but repeating decimal part.
  2. 1/3 is rational, because it's the division between two integers
  3. -\sqrt{16}=-4, so this is rational as well.

Since the product of two rational numbers is always rational, we have that

0.\bar{7}\cdot \dfrac{1}{3},\quad \dfrac{1}{3}\cdot \dfrac{1}{3},\quad -4\cdot \dfrac{1}{3}

are all rationals, since they are the product of two rationals.

On the other hand, we have

\sqrt{27}=\sqrt{9\cdot 3}=3\sqrt{3}

and thus

3\sqrt{3}\cdot \dfrac{1}{3}=\sqrt{3}

which is irrational.
