How does a 180 degree rotation about the origin change the coordinates of a shape

According to the 180°-rotation rule, you take the OPPOSITE of both the x-coordinate and y-coordinate:

180°: [x, y] → [-x, -y]

The correct answer is A) 0.5531.

We find the z-score associated with each of these values using the formula
z = (X-μ)/σ

z = (125-134)/4.8 = -9/4.8 = -1.875 ≈ -1.88

Using a z-table (http://www.z-table.com), we see that the area under the curve to the left of, less than, this is 0.0301.

z = (135-134)/4.8 = 1/4.8 = 0.2083 ≈ 0.21

Using a z-table (http://www.z-table.com), we see that the area under the curve to the left of, less than, this is 0.5832.

We want the area between them, so we subtract:
0.5832-0.0301 = 0.5531
