Your teacher has 50 pencils. 9 of the pencils are green, 10 are yellow, 7 are

Mathematics

Answer:

B. Dependent, 1/70

Step-by-step explanation:

The probability that the first pencil is yellow is 10/50.

There are now 49 pencils, so the probability that the second pencil is blue is 7/49.

There are now 48 pencils, so the probability that the third pencil is red is 24/48.

The total probability is (10/50) (7/49) (24/48) = 1/70.

Since the pencils aren't replaced after selection, each event changes the probability of the next, so the events are dependent.

Is the​ equation's graph opening up or​ down?
Inessa05 [86]

Answer:

Step-by-step explanation:

Your "y=2xsquared-12x+10" translates into y = 2x^2 - 12x + 10.  This factors into y = 2(x^2 - 6x + 5).

Setting this = to 0 results in y = 2(x - 5)(x - 1) = 0, so that the x-intercepts are (5,  0) and (1, 0).  The x-coordinate of the vertex lies halfway between x = 1 and x = 5, that is, at x = 3.  Using synthetic division to evaluate y = 2x^2 - 12x + 10 at x = 3, we get

3    2    -12    10

              6    -18

     ------------------

      2     -6     -8

Therefore, the vertex is located at (3, -8).

Setting x = 0 results in the y-intercept:  y = 2(0)^2 - 12(0) + 10 => (0, 10)
