Answer: D. History

Step-by-step explanation:

To answer this question, we need to use the z-score formula written below:

$\frac{x-pop. mean}{stan. devi.}$

Now we'll just plug in the numbers and solve.

History:

$\frac{85-65}{5} = 4$

Biology:

$\frac{90-85}{10} =0.5$

As we can see, history wields a higher z-score than biology, thus leaving us with option D. History

triangle ABC is reflected about the line Y equals negative X to give triangle ABC with vertices A (-1, 1), B (-2, -1), C (-1,0).

Amiraneli [1.4K]

Answer:

A'(-1, 1)
B'(1, 2)
C'(0, 1)

Step-by-step explanation:

Reflection across the line y = -x is accomplished by the transformation ...

(x, y) ⇒ (-y, -x)

Then the images of the given points are ...

A(-1, 1) ⇒ A'(-1, 1) . . . . this point is on the line of reflection, so doesn't move

B(-2, -1) ⇒ B'(1, 2)

C(-1, 0) ⇒ C'(0, 1)
