Flauer [41]

Answer:

(a) seems to be the closest to being correct of these five statements.

Step-by-step explanation:

Let's go through the list of possible descriptors:

a) There are no outliers.  This seems to be the response most likely to be correct.

b) The distribution is not skewed left.  It's skewed right.

c) The center is not 44.  From what I see, the center is 48.

d) This distribution is not bimodal; it does not have two peaks.

d) The spread is not 38 to 67; it's 29 to 67.

In-s [12.5K]

since line AB and CD make all right angles (given) angles 6+7+8 will equal 90 degrees.


According to the verticle angles rule:

angle 2 is equal to angle 6

angle 3 is equal to angle 7

angle 4 is equal to angle 8.


which proves that angle 2+4+7=90 degrees
