Answer:

  C.

Step-by-step explanation:

The mapping for 90° counterclockwise rotation is ...

  (x, y) ⇒ (-y, x)

If we consider how this applies to points X and Y, which both have a y-coordinate of 0 and a negative x-coordinate, (-a, 0), for example, we see it maps to ...

  (-a, 0) ⇒ (0, -a)

That is, both points X' and Y' will be on the negative y-axis. The only figure showing this is figure C.

______

<em>Comment on the other answer choices</em>

Figures A and D show <em>clockwise</em> rotation. In Figures A and B, the rotation is <em>not</em> about the origin, but is about a different point. (In Figure B, the points easy to consider are the ones on the -x axis, points X and Z. They should appear on the -y axis after rotation, but do not.)

Suppose a six-sided die is tossed 1200 times and a 6 comes up 419 times. (a) Find the empirical probability for a 6 to occur. (E
krok68 [10]

Answer:

Here both probabilities are not equal.

Therefore the die is not fair and biased.

Step-by-step explanation:

Now n= 1200 times and x = 419 times.

a) Empirical Probability:

         =\frac{x}{n} \\\\= \frac{419}{1200}\\ \\=0.349

Probability = 0.349

b) Theoretical Probability:

                     =\frac{1}{6}

Here both probabilities are not equal.

Therefore the die is not fair and biased.

Theorems are understood as true and do not need to be proved.<br><br> True<br><br> False
patriot [66]

The answer is FALSE. Theorem, as applied in mathematics, is a statement that has been proved having a basis of laborious mathematical reasoning. The statement that is assumed to be true without proof is called axiom or postulate. Theorems are proved using axioms.
