help Kyle trying to explain to her friend why the placement of an ange and the concept of rigid motions can be used in determini
ng triangle congruence. She illustrates the SAS triangle corerence and the SSA possibility as shown in the diagram with two pairs of triangles. What do you think Kyle said to her friend about the placement of angles and about the relationship between the triangle pairs in terms of rigid motions? Using Kyle's illustration, write an argument for why the placement of the anges and the concept of rigid motions in proving triangle congruence can be critical A E E

Answer:
The correct option is (b).
Step-by-step explanation:
If X N (µ, σ²), then
, is a standard normal variate with mean, E (Z) = 0 and Var (Z) = 1. That is, Z
N (0, 1).
The distribution of these z-variate is known as the standard normal distribution.
The mean and standard deviation of the active minutes of students is:
<em>μ</em> = 60 minutes
<em>σ </em> = 12 minutes
Compute the <em>z</em>-score for the student being active 48 minutes as follows:
Thus, the <em>z</em>-score for the student being active 48 minutes is -1.0.
The correct option is (b).
